OBJECTIVE: To investigate the dental practitioner's knowledge, attitude and practice towards dental implants. METHODOLOGY: This study was carried out from May'2019 - Oct 2019. 752 dental practitioners who were currently practicing were included in the study. A well-structured questionnaire was used for data collection. SPSS-25 was used for statistical analysis. Spearman correlation was used to find the effect of gender, knowledge and attitude. The P <0.05 was considered statistically significant. RESULTS: In this study 80.9% dental practitioners were aware of the appropriate implant material while, 57.9% had knowledge about the types. 30.3% knew about the implant surface modifications whereas 46.1% dentists were aware of possible implant placement approaches. 49.3% believed that the distance between dental implants to be 3mm and between a dental implant and natural tooth to be 1.5 mm. 76% dentists claimed that dental implants have biomechanical complications. Whereas 67.8% knew about the Branemark's theory of osseointegration. Regarding the attitude of dental practitioners, 28.9% had received implant hands on trainings while 9% felt competent to place an implant. CONCLUSION: This study describes that dental practitioners had an appropriate knowledge of each aspect of implantology. Moreover despite the fact majority felt that they are not competent enough to practice it. Thus, it is important that the curriculum, teaching standards, the materials and methods regarding dental implants need to be reviewed and more exposure of hands-on workshops is to be provided not only for the graduates but also the undergraduates during their clinical learning.

Patients with total edentulism can be treated with fixed or mo- bile prosthetic implant rehabilitation with dental implants as part of implanto-prosthetic therapy. Of the three dental implant loading options/protocols (conventional, early loading, and im- mediate loading), removable prosthetic works are most often conventionally loaded and then they represent standard and reliable forms (with a high success rate) of implanto-prosthetic therapy.

INTRODUCTION: Identification of dental implant types can be a complex process for inexperienced health care professionals. Dental implants can have subtle differences in their morphology, which make it difficult to distinguish them from one another The unique appearance of dental anatomy and the placement of custom restorations ensure accurate identification of bodies or human remains when radiographic techniques are correctly applied. AIMS AND OBJECTIVES: To develop a radiographic dental implant guide for ten common dental implant types currently used in the Western Cape, South Africa; using their morphological characteristics observed on pantomographs. DESIGN: The methodology considered for this research study was a positivist approach through a quantitative, exploratory, non-experimental research design. METHODS: Ten commonly used dental implants were radiographed at straight tube (ST), off-centre (OC) and severe off-centre (SOC) angles to create a reference instrument Two reviewers used the morphologies of the different dental implant types, namely the apex, thread and neck, observed on ante-mortem pantomographs, and compared it to the appearance of the dental implants in the reference instrument to make a positive identification match. The straight tube image of all ten dental implant types in the reference instrument was used as the initial point of reference to positively identify the morphological characteristics of each dental implant type on the pantomographs. RESULTS: A total of 380 dental implants could be identified on 105 pantomographs reviewed. Of the 380 dental implants, 350 dental implants (91%) were identified as dental implant types listed in the reference instrument while 30 dental implants were identified as another type of dental implant type not listed in the reference instrument A total of 208 dental implants (54.2%) could be positively identified on the ante-mortem pantomographs using the straight tube images in the reference instrument. The morphological characteristics of the dental implant types were described using x-ray imaging of dental implants. The ten commonly used dental implants types could be positively identified by two independent reviewers and based on this a radiographic dental implant guide was developed. CONCLUSION: Each dental implant type had unique morphological characteristics as well as similarities which enabled distinction between the different dental implant types. The dental implant guide developed could be used by dentistry and radiography students. The dental implant guide may be useful in the field of forensic dentistry and forensic radiology.

Objectives: The demand for dental care is expected to increase as the population ages. This study aimed to predict the utilization of dental implant care following the expansion of national health insurance benefits for dental implants. Methods: Multiple linear regression analysis was performed on HIRA big data open portal data and DNN-based artificial intelligence models to forecast the utilization of dental care in relation to the national health insurance coverage for dental implants. Results: National health insurance coverage of dental implants was found to be associated with the number of patients using dental implant services and demonstrated a statistical significance. The dental implant services utilization increased with the increased dental implant health insurance benefits for the elderly population, increased mean by region, increased number of dental institutions by region, and increased health insurance coverage rate for dental implants. However, the dental implant services utilization decreased with the increased number of older people living alone and increased size of dental institutions. Conclusions: With the expansion of the national health insurance coverage for dental implants, it is predicted that the utilization of dental implant medical services will increase in the future.

Full textAbstract:
Data on dental implant treatment's success and survival rate are still limited. Meanwhile, the data on the success and survival after implant placement and restoration can be used to evaluate materials, improve the dental implant treatment, and enhance the service quality at Hasanuddin University Dental Hospital. The purpose of this study is to analyze the dental implant survival rate, the contributing factors that enhance the survival rate, and the factors causing the failure of the dental implants at the Prosthodontic Clinic of Dental and Oral Hospital, Hasanuddin Uni-versity. The final study group consisted of 11 patients with 20 implants. Implant failure was categorized based on implant loss, mobility, or removal due to severe peri-implant infection or implant fracture. Implant survival rates were grouped based on sex, age, smoking habit, placement location, diameter, length, and placement time. The value of implant survival rate was assessed based on the presentation of successful implants. Of all 20 cases, five implants failed, indicating a cumulative implant survival rate of 75%. Based on the failure period, there are initial failure cases before loading and late failure cases after loading. One implant failed within the first six months, and two implants failed 2 years after insertion of the superstructure. The leading cause of implant failure before loading is osseointe-gration failure. In the case of implants that failed after installing the superstructure, peri-implantitis occurs continous-ly. It was concluded that the implant survival rate for patients at the Hasanuddin University Dental Hospital is 75%. Dental implant survival rates include gender, age, implant placement location, smoking habits, implant diameter, length, and immediate or delayed implant placement. The factors causing the failure of the implant in this study were osseointegration failure and peri-implantitis

Full textAbstract:
The lack of compatible prosthetic components can be a complication during oral rehabilitation using outdated implants. The aim of the present clinical report was to describe an alternative technique for the fabrication of a maxillary implant-supported overdenture in a patient with 20-year-old dental implants using castable spherical patterns and ball attachments. The patient had been wearing a relined bar/clip overdenture in the mandible on 4 external-hexagon dental implants and a relined complete denture in the maxilla on 4 internal-hexagon implants due to abutment screw fracture inside of the implants, losing the attachment system. The remaining maxillary dental implants did not possess attachments compatible with current systems due to configuration changes by the manufacturer in the dental implant's platform and the components over time. Therefore, castable spherical patterns and cast ball attachments were used to fabricate a maxillary implant-supported overdenture. The mandible rehabilitation was performed using 4 osseointegrated dental implants with a fixed implant-supported prosthesis. The use of cast ball attachments on the maxillary dental implants avoided invasive procedures on the remaining implants. Considering the lack of available compatible prosthetic components for the osseointegrated implants, this technique was considered a viable and satisfactory treatment option.

The aim of this prospective cohort observational field trial was to examine 1-year survival and success rates of a recently introduced tapered implant system with switched platform conical abutments and to evaluate patient related outcomes of therapy. Partially edentulous patients aged between 18 and 75 years, with available bone height for dental implants ≥10 mm desiring to restore the missing tooth/teeth with implant supported restoration, were recruited by 7 periodontists in their respective private practices. Dental implants were installed according to standard implant therapy protocol. Three to 6 months postoperatively, after evaluating interim implant success, implants were restored by the referring dentists. Patient, Ramfjord teeth, and implant data, including baseline and 1-year postoperative, were collected. A total of 60 patients were recruited and received 117 implants. Complete 1-year clinical and radiographic data were available for 83 and 65 implants, respectively. Two implants failed during the first year, resulting in a 1-year survival rate of 98.3%. Mean implant probing pocket depth was 2.29 ± 0.84 mm. Mean radiographic bone distance from implant's shoulder at the mesial and distal sites at 1 year was 0.66 ± 0.5 and 0.79 ± 0.64mm, respectively, resulting in a success rate of 95.4%. Patient subjective evaluation of therapy exhibited a median pain experience of 1 and median esthetics, function, and general satisfaction evaluation of 10 on a scale of 1 to 10. The tapered conical connection dental implant system, used in private dental practices, shows good 1-year survival and success rates that are similar to other implant systems on the market.

Background. Improving the implantation conditions in order to reduce the failure is always desirable for researchers. The aim of this study was to compare two different types of dental implant materials from biomechnical viewpoint in order to introduce a novel simulation method to select suitable materials for dental implants. Methods. In this research, drilling process was performed in the cortical bone of the mandible by finite element analysis simulation. Then, a 3D model of the produced hole in the drilled site was derived and a dental implant model by ITI design was inserted into the cavity. The space remaining between the implant and cavity was considered as a newly formed cortical bone area. Implant loading was performed on two dental implants with different types of material. The change in the volume of the cortical bone around each implant was considered a criterion for evaluating bone damage. Additionally, the micromotion of dental implant in the mandible after implantation was used for investigating dental implant stability. Results. After implant loading, the volume changes in newly formed cortical bone around Ti and Zr-2.5%Nb dental implants were measured at 0.010809 and 0.010996 mm3 , respectively. Furthermore, micromotion of Ti and Zr-2.5%Nb dental implants were measured at 0.00514 and 0.00538 mm, respectively. Conclusion. This study showed that Ti dental implant creates better conditions than Zr-2.5%Nb dental implant in the maxillofacial region

Purpose. To investigate effects of number and location on patterns of von Mises stress distribution and volume average stress on abutment tooth, edentulous ridge, mini dental implant, and surrounding bone of mini dental implant-assisted mandibular Kennedy class I removable partial denture. Materials and Methods. Eight three-dimensional finite element models of mandibular Kennedy class I with different numbers and locations of mini dental implants were constructed. Mini dental implants were generated in the area of second premolar, first molar, and second molar, respectively. A static load of 400 N was applied on all models. The von Mises stress and volumetric average stress were calculated by three-dimensional finite element analysis. Result. The minimum volumetric average stress of abutment tooth was found in the model, where there was one mini dental implant at the second molar position and 2 mini dental implants at first molar and second molar positions. The model with three mini dental implants had reduced volumetric average stress of abutment tooth, which was not different from the model with two mini dental implants. However, the minimum volumetric average stress of mini dental implant and surrounding bone were found when three mini dental implants were applied, followed by two and one mini dental implants, respectively. Conclusion. Placing at least one mini dental implant at a second molar position can help reduce stress transferred to the abutment tooth. Stresses around each implant and surrounding bone reduced with increased numbers of mini dental implants.

ABSTRACT Objective: A comparative study between threaded and plain dental implant designs was performed to find out a new criterion for dental implant selection. Materials and Methods: Several dental implant designs with a systematic increase in diameter and length were positioned in a cylindrical-shaped bone section and analyzed using finite element method. Four loading types were tested on different dental implant designs; tension of 50 N, compression of 100 N, bending of 20 N, and torque of 2 Nm, to derive design curves. Results: Better stress distribution on both spongy and cortical bone was noted with an increase in dental implant diameter and length. With the increase in dental implant side area, a stress reduction in the surrounding bones was observed, where threaded dental implants showed better behavior over the plain ones. Conclusions: Increasing value of ratio between dental implant side area and its cross-sectional area reduces stresses transferred to cortical and spongy bones. The use of implants with higher ratio of side area to cross-section area, especially with weak jaw bone, is recommended.

Full textAbstract:
Achieving primary stability in dental implants is crucial factor for accomplishing successful osteointegration with bone. Micro-motions higher than the threshold of 50 to 100 μm can lead to formation of fibrous tissue at the bone-to-implant interface. Therefore, osteointegration may be vitiated due to insufficient primary stability. Osseointegration is defined as a direct and functional connection between the implant biomaterial and the surrounding bone tissue. Osseointegration development requires an initial rigid implant fixation into the bone at the time of surgery and a secondary stage of new bone apposition directly onto the implant surface. Dental implants function to transfer the load to the surrounding biological tissues. Due to the absence of a periodontal ligament, its firm anchorage to bone, various forces acting on it and the presence of prosthetic components, they share a complex biomechanical relationship. The longevity of these osseointegrated implants depend on optimizing these complex interactions. Hence, the knowledge of forces acting on implant, design considerations of implant and bone mechanics is essential to fabricate an optimized implant supported prosthesis.

Background: Metallic dental implant materials play a pivotal role in modern dentistry, serving as a key component in the restoration of missing teeth. Patients' knowledge and experiences related to these metallic materials are essential aspects in understanding the overall success and acceptability of dental implant procedures. Objective: To determine the patients' knowledge and experience (satisfaction and problems) associated with Metallic Dental Implant Material. Study Design: Cross-sectional survey-based study. Settings: Bhittai Dental Hospital Mirpur Khas and Hamdard University, Dental Hospital, Karachi Pakistan. Duration: Six months from march 2021 to August 2021. Methods: All the patients above 18 years of age, both gender, individuals who have previously undergone dental implant procedures involving metallic materials, those who are considering dental implant procedures with metallic materials were included. Data was collected using a structured questionnaire consisting of closed-ended questions regarding patients' knowledge and experience associated with metallic dental implant material. Data analysis was done by using SPSS version 26. Results: A total of 89 individuals were interviewed; out of them 55.15 were females and 44.9% were males. Most of the cases had heard about dental implant by medicos, random people and relatives. 37.1% patients had financial issues regarding dental implants, 25.8% had pain/discomfort after having an implant, 31.5% cases were facing to infection, 67.4% cases had limitation regarding meals after having a dental implant. Out of all 57.3% individuals were satisfied regarding their dental implants. Conclusion: Patients' knowledge and experience associated with metallic dental implant material observed to be average. Financial, fear of surgery, discomfort and infection issues were a major concern for a significant proportion of patients, indicating that cost may be a barrier to receiving dental implants for some patients. Despite these challenges, the majority of patients expressed satisfaction with their dental implants, indicating that the benefits of the procedure may outweigh the challenges.

In oral rehabilitation with dental implants, severely resorbed alveolar ridges are a challenging problem due to the reduced height of the residual bone. Continuous search for minimally invasive procedures has resulted in the conception of reduced-length dental implants, decreasing the necessary amount of bone for implantation, thereby reducing the need of bone-grafts. Given the growing demand in the field of implant dentistry and the continuous development of surgical techniques, this study aimed to review the current literature on the predictability and success rate of short implants. Relevant articles published in the PubMed database between the years of 2004 and 2014 were selected using the following key-words: short dental implants, extra-short implants, survival rate, implant, mandible, maxilla, prognosis, implant survival, implant length. Based on the literature review, we concluded that short implants showed high predictability and high success rate in the short term, therefore they are one of the current options for the rehabilitation of atrophic alveolar ridges. Further longitudinal studies are necessary to define more reliably parameters for their proper use, ensuring the achievement of high success rates and survival rates with the use of this type of implant.o assess the attitude and practice of dental professionals towards using of advance radiographic technique.

Background & Objectives: The use of dental implants in partially or completely edentulous patients has proved effective and an accepted treatment modality with predictable long-term success. Dental implants are becoming a popular choice for replacing the missing teeth because of increased awareness about implants both in dentists and patients. The objective of the study was to assess the basic knowledge and education about dental implants among general dental practitioners (GDPs) of Nepal.Materials & Methods: A cross sectional questionnaire was carried out among 110 GDPs which consist of twenty questions that were divided into three categories; first with some basic knowledge in implant dentistry, second with clinical knowledge of dental implants and third with dental implant education and training.Results: Out of 110 GDPs, 72.7% had basic knowledge about implant dentistry and 65.5% were not aware about advance surgical procedures like sinus lift and guided bone regeneration. All the GDPs were positive regarding more training and education in dental implants and 95.5% of them would like to incorporate dental implant treatment in their practice in future. Conclusion: GDPs should have adequate knowledge and training of dental implants which can be incorporated at undergraduate or post doctoral level so that they are skilled to provide quality dental implant therapy to their patients confidently.

The objectives of this study were to evaluate osseointegration of dental implant in the jaw bone in the young and elderly population and comparing the results to assess indicators and risk factors as age for the success or failure of dental implants. A retrospective study of 107 implants (Impladent, LASAK, Czech Republic) was prepared. The patients at implants surgery were divided in three groups. The patients were followed-up for a 7-year period. We evaluated osseointegration from long term point of view as a change of marginal bone levels close to dental implant. Marginal bone levels were recorded and analysed with regard to different patient- and implant-related factors. An influence of chronological age on change of marginal bone levels during 6-year retrospective study vas evaluated. The study examined 47 patient charts and 107 implants from the Second Faculty of Medicine, Charles University and University Hospital Motol. We proved that young healthy patients with long bridges or Branemarks have the same progression of marginal bone levels changes. The chronological age hasn’t therefore direct influence on the osseointegration from long term point of view. But we found that the length of dental suprastrucure-prosthetic construction negatively influences marginal bone changes, though these results weren’t statistically significant. More extensive dental implant suprastrucure undergoes smaller osseointegration. On the other hand the length of dental suprastrucure (prosthetic construction) negatively influences dental osseointegration in both groups of patient.

Dental implants are widely used tooth replacement tools owing to their good oral rehabilitation and reconstruction capacities. Since dental implants are designed as a replacement for natural teeth, multi-functional abilities are desired to achieve successful implant treatment with improved osseointegration through promotion of mammalian cell activity and prevention of bacterial cell activity. In this study, we developed a graphene–chitosan hybrid dental implant (GC hybrid implant) using various concentrations of graphene, which demonstrated the different surface properties including increased wettability and roughness. Importantly, the GC hybrid implant under the optimal condition (i.e., 1% GC hybrid implant) could significantly promote osteoblast proliferation while reducing biofilm formation and bacterial activity. Our study demonstrates the potential of using this GC hybrid implant as a new type of dental implant, which can offer an effective design for the fabrication of advanced dental implants.

In a daily routine practice dental implants has been widely used and dental implants are considered as a one of the good treatment option in replacing the single tooth in the oral cavity or replacing the multiple teeth in the oral cavity. With the use of dental implants, a dentist can replace the single tooth or multiple teeth or with the help of dental implants one can provide the whole full arch implant supported prosthesis. The survival rate of the implants are dependent on so many conditions , like patient systemic condition, bone quality and amount of bone available, sterilization protocol during the placement of the implant. In some cases failing of implant were also seen due to systemic condition, due to mechanical failure such as loosening of the implant, loosening of the screw. So a dentist should have a basic knowledge of the implant along with its all components, causes of implant failures and how to avoid the causes of implant failure as well as how to manage.

Abstract Titanium and titanium alloys are widely used for fabrication of dental implants. Because of potential immunologic and possible esthetic compromises with titanium implants, novel implant technologies are being developed. However, these novel technologies must maintain the characteristics that provide titanium implants with their high success rates. Zirconia implants were introduced into dental implantology as an alternative to titanium implants. Zirconia seems to be a suitable implant material because of its toothlike color, mechanical properties, biocompatibility, and low plaque affinity. The aim of this study is to review clinical and research articles conducted on zirconia dental implants, compare them with titanium dental implants, and provide information on zirconia dental implant osseointegration and mechanical strength. Zirconia dental implants have the potential to become alternative dental implants to titanium dental implants, but they are not yet in routine clinical use.

The objective of this research was to investigate dental bridges with and without implants. Threedimensional (3D) mandible models were reconstructed by computer tomography (CT) to simulate biting behaviors. The dental implant is an important factor in dental bridge applications. Several studies have investigated finite element models for dental implants; however, few have examined a model for dental bridge with implant. The results revealed that stress was significantly increased when dental bridge was used with implant. Moreover, the dental bridge with implant group demonstrated a relatively big stress in mandible, which was 4.01% lower compared with that of the control group. Dental bridge would be an effective means of recovering dental performance. However, the present research stated that the implant of dental bridge has a potential to increase abnormal stress, and uniformly distributing stress in the dental bridges.

The development of dental implant science and technology has developed rapidly, the installation of dental implants is an option in replacing missing teeth. Recently, the construction of denture bridges with implant supports has been widely used and is often successful, however this does not rule out the possibility of failure in dental implant treatment. Granting additional authority to dentists with the aim of equal distribution of health services in Indonesia, there are no rules that clearly regulate the authority of dentists in placing implant dentures. This research is structured using the type of normative legal research, namely research that is focused on examining legal norms in an applicable statutory regulation related to the subject matter. The purpose of this study was to analyze the authority of dental implant placement by dentists and to analyze the legal consequences associated with the risk of dental implant placement in patients. The results of this study indicate that dental implants are the clinical authority of specialist dentists, dentists' authority in installing dental implants is limited to theoretical understanding, regarding various types of dental implant therapy, mastering application theories in dental implant cases only. Regarding the risk of failure in installing dental implants by dentists, legal remedies that can be taken by patients for losses experienced are by way of a civil suit to the local district court on the basis of liability for losses due to unlawful acts

Today, an artificial tooth root called a dental implant is used to replace lost tooth function. Treatment with dental implants is considered an effective and safe method. However, in some cases, the use of dental implants had some failures. The success of dental implants is influenced by several biomechanical factors such as loading type, used material properties, shape and geometry of implants, quality and quantity of bone around implants, surgical method, lack of rapid and proper implant surface's integration with the jaw bone, etc. The main purpose of functional design is to investigate and control the stress distribution on dental implants to optimize their performance. Finite element analysis allows researchers to predict the stress distribution in the bone implant without the risk and cost of implant placement. In this study, the stresses created in the 3A.P.H.5 dental implant's titanium fixture and screw due to the change in abutment angles tolerance have been investigated. The results show that although the fixture and the screw's load and conditions are the same in different cases, the change of the abutment angle and the change in the stress amount also made a difference in the location of maximum stress. The 21-degree abutment puts the fixture in a more critical condition and increases the chance of early plasticization compared to other states. The results also showed that increasing the abutment angle to 24 degrees reduces the stress in the screw, but decreasing the angle to 21 degrees leads to increased screw stress and brings it closer to the fracture.

One of the recent advances in the field of dentistry is to provide prothesis that can replace lost natural teeth. Over several decades, researches were endeavouring to create dental implants with optimized criteria that allow long-term function and stability. After notable success, the use of dental implant has become an almost daily routine in dental practice. However, many factors can influence the success of dental implantation procedures. Primary implant stability remains the most reliable predictor of dental implants success, and many factors are known to have a considerable impact on the implant stability such as the thread morphology, the implant size and length, the implant body shape, the surgical technique use, and the underlying bone heath. Knowledge of these factors is essential for optimizing the outcome of dental implantation procedures even in unfavourable conditions. Therefore, this article aims at reviewing and discussing the various dental implants designs, characteristics, and stability.

Many patients travel abroad seeking cosmetic dental treatment, in particular dental implants. However, there are hundreds of dental implant systems being used globally by dentists of all training backgrounds. Furthermore, complications can occur that patients may expect their general dental practitioner in the UK to be able to manage. The following report describes the case of a 71-year-old, medically compromised patient who presented with complaints consistent with the immediate failure of dental implants that happened to be placed abroad. On closer examination, the dental implants themselves were highly questionable in their design and placement. An incidental finding was also made in the maxillary sinus. CPD/Clinical Relevance: To acknowledge that implant dentistry is increasing in popularity as patients have the freedom to access dental implant treatment globally. UK dentists are expected to manage these dental implants on the return of patients to the UK who may present with post-operative complications involving unknown dental implant systems.

Dental implants, or completely said as dental implant bodies, function as analogues of tooth roots, achieving aunion directly with jawbone following their insertion into a prepared socket in the bone. Implant system have threebasic components, namely the dental implant body that is lying in the jawbone, abutment that lies on the jawboneand the prosthesis. Dental implants may stabilize a removable prosthesis, complete or partial overdentures, and orsupport and stabilize a fixed prosthesis. In designing implant-supported removable prostheses, there are three formsof anchorage frequently used, namely bar/sleeve (clip) joints which links two or more implants, ball/cap anchoragesapplied individually to two or more isolated implants, and magnets/magnetic keepers. Implant-supported fixedprosthesis is either screwed to or cemented on to the abutment.

Today, in clinical practice, the loss of marginal bone mass around dental implants in the early stages after the installation and opening of the implant is increasingly common. Early clinical publications suggested that this bone loss occurred during the first year of prosthetics. Thus, numerous attempts have been made to minimize or eliminate such bone loss. However, the timing and cause of bone loss are not always obvious. The purpose of this review was to analyze data on marginal bone loss around dental implants in terms of biological implications to help understand changes in marginal bone around dental implants. One hypothesis for bone loss around dental implants has been related with infected interface between the implant and abutment. This review article shows that bone loss of 1.5 to 2.0 mm occurred around implant-abutment junctions at the bone level. The bone loss level was correlated with implant-abatement interface size. Recent publications indicate that such dental implant systems with large prosthetic-implant gaps may cause peri-implantitis with further implant loss.

Background/Aim. Flapless implant surgery has become very important issue during recent years, mostly thanks to computerization of dentistry and software planning of dental implants placements. The aim of this study was to compare flap and flapless surgical techniques for implant placement through radiographic and radiofrequency analyses. Methods. The experiment was made in five domestic pigs. Nine weeks following domestic pigs teeth extraction, implants were placed, on the right side using surgical technique flap, and flapless on the left side. Digital dental Xrays were applied to determine primary dental implant stability quality (ISQ). At certain intervals, not later than three months, the experimental animals were sacrificed, and just before it, control X-rays were applied to measure dental implants stability. Results. Radiographic analysis showed that peri-implant bone resorption in the first 4 weeks following placement implants with flap and flapless surgical techniques was negligible. After the 3 months, mean value of peri-implant bone resorption of the implants placed using flap technique was 1.86 mm, and of those placed using flapless technique was 1.13 mm. In relation to the primary dental implant stability in the first and second week there was an expected decrease in ISQ values, but it was less expressed in the dental implants placed using the flapless technique. In the third week the ISQ values were increased in the dental implants placed by using both techniques, but the increase in flapless implant placement was higher (7.4 ISQ) than in flap implant placement (1.5 ISQ). The upward trend continued in a 4- week period, and after 3 months the dental implant stability values in the implants placed using flap technique were higher than the primary stability for 7.1 ISQ, and in the implants placed using flapless technique were higher comparing to the primary stability for 10.1 ISQ units. Conclusion. Based on the results of radiographic and resonance frequency analyses it can be concluded that the flapless technique in surgical implants placemat, leads to better results.

Objective:
To assess the possible risk factors that contribute to early dental implant failures in a teaching hospital.
Materials and Methods:
This cross sectional study evaluated past records of the 24 patients treated with 53 dental implants and were divided into two groups, one with failed dental implants before occlusal loading and the other with successful implants. Variables such as Age, gender, location of implants (maxilla or mandible), type of implant healing (single or double stage) and timing of implant placement (fresh extraction sockets or healed sites) were assessed.
Results:
About 4 (7.5%) out of 53 dental implants failed to osseointegrate before the prosthetic phase. The difference between the two groups was statistically significant p= 0.032 regarding the healing of dental implant (single or double stage), however, it was not significant in terms of age, gender, site and timing of implant p>0.05.
Conclusion:
Single stage implant surgery may be an important risk factor for early Implant failure however, more studies with larger sample size should be done to investigate risk factors that contribute to early failures.

The aim of the present research was to evaluate the biomechanics of dental bridge with and without implant. Oral models were reconstructed by 3D computer tomography images to simulate oral environment. The stress is an important role in dental bridge applications for osseointegration. Many studies have investigated finite element researches for dental implants; however, few have evaluated a model for dental bridge with and without implant. The results revealed that abnormal focusing stress was found when dental bridge was used with implant. Moreover, the unbalance situation was found on the model with only one implant, the highest stress appeared in the present group. Dental bridge with implants would be an effective means of recovering dental performance. However, the present study showed that if only one pier with dental implant in bridge treatment has a potential to increase abnormal stress, and uniformly distributing stress.

ABSTRACT Introduction One of the most common and effective ways of replacing missing teeth is by dental implants. Both quality and quantity of bone along with the area of implant placement govern the prognosis of the implant procedure. Certain risk factors predispose the implant treatment to high failure rate. Hence, we assessed the implant patients who were referred from private practitioners to the specialty hospitals from 2010 to 2014. Materials and methods All the patients being referred from private clinics to the specialty dental hospital for the purpose of prosthetic rehabilitation by dental implants from June 2010 to July 2014 were included in the present study. Skilled oral and maxillofacial surgeons were appointed for performing the implant surgical procedures. Prosthetic rehabilitation was done after 6 to 8 weeks and after 10 to 14 weeks in implant cases without and with bone augmentation procedures respectively. Distribution of dental implants based on the indications, location, dimension of augmentation procedure, and complication of implants was analyzed and assessed for the level of significance. Results Of the patients, 712 were females, while the remaining were males. Most of the patients were in the age group of 50 to 59 years. As compared with completely edentulous patients, most of the patients required rehabilitation by a single implant. Maximum dental implants were placed in maxillary premolar region and mandibular first molar region. Over 1,000 cases in this study required rehabilitation by augmentation procedure. Conclusion Partially edentulous patients are most commonly referred to specialized dental hospitals for prosthetic rehabilitation by dental implants, mostly with the purpose of implant placement. Failure rate can be minimized by following strict patient selection protocols along with following a standard surgical criterion. Clinical significance Following standard surgical protocols and strict treatment planning, prognosis of the dental implant procedures can be improved to a greater extent, thereby increasing its clinical success rate.

The purpose of this study was to analyze the influence of the digital mock-up and operator experience on the dental implant planning position. A total of 200 dental implants were planned, which were distributed into two study groups: A. dental implant planning by dental surgeons with 5–10 years of experience (n = 80); and B. dental implant planning by dental surgery students without experience (n = 120). Operators were required to plan eight dental implants in the same maxillary edentulous case uploaded in 3D implant-planning software, before and after using the digital mock-up. Deviations between the dental implant planning positions before and after using the digital mock-up were analyzed at platform, apical and angular levels, and were analyzed using a 3D implant-planning software using Student’s t test. The paired t-test revealed statistically significant differences between the deviation levels of participants with 5–10 years’ experience and no experience at the platform, apical and angular levels. Digital mock-ups allow for more accurate dental implant planning regardless of the experience of the operator. Nevertheless, they are more useful for operators without dental surgery experience.

ABSTRACT Introduction Ever since its introduction in 1977, a minimum of few months of period is required for osseointegration to take place after dental implant surgery. With the passage of time and advancements in the fields of dental implant, this healing period is getting smaller and smaller. Immediate loading of dental implants is becoming a very popular procedure in the recent time. Hence, we retrospectively analyzed the various risk factors for the failure of delayed and immediate loaded dental implants. Materials and methods In the present study, retrospective analysis of all the patients was done who underwent dental implant surgeries either by immediate loading procedure or by delayed loading procedures. All the patients were divided broadly into two groups with one group containing patients in which delayed loaded dental implants were placed while other consisted of patients in whom immediate loaded dental implants were placed. All the patients in whom follow-up records were missing and who had past medical history of any systemic diseases were excluded from the present study. Evaluation of associated possible risk factors was done by classifying the predictable factors as primary and secondary factors. All the results were analyzed by Statistical Package for the Social Sciences (SPSS) software. Kaplan–Meier survival analyses and chisquare test were used for assessment of level of significance. Results In delayed and immediate group of dental implants, mean age of the patients was 54.2 and 54.8 years respectively. Statistically significant results were obtained while comparing the clinical parameters of the dental implants in both the groups while demographic parameters showed nonsignificant correlation. Conclusion Significant higher risk of dental implant failure is associated with immediate loaded dental implants. Tobacco smoking, shorter implant size, and other risk factors play a significant role in predicting the success and failure of dental implants. Clinical significance Delayed loaded dental implant placement should be preferred as they are associated with decreased risk of implant failure.

ABSTRACT This study addresses the durability and complications of zirconia dental implants through a prospective clinical investigation. Zirconia implants are increasingly utilized in dental implantation, and a comprehensive understanding of their long-term performance is essential. Background: Zirconia dental implants have gained attention due to their biocompatibility and aesthetics. However, research on their extended success and complication rates is limited. Materials and Methods: A prospective clinical study involved the placement of 30 zirconia dental implants in patients requiring tooth replacement. The implants were followed up for five years. Success was defined as the implant remaining stable and functional. Complications, including peri-implant mucositis and peri-implantitis, were monitored. Statistical analysis included descriptive statistics, Chi-square test, and P-values were set at P < 0.05. Results: The long-term success rate of zirconia dental implants was found to be 93.3%. Among the 30 implants, only 2 exhibited failure. The most common complication was peri-implant mucositis, occurring in 16.7% of implants. Notably, the incidence of peri-implantitis was limited, observed in 6.7% of implants. Statistical analysis showed significant associations between implant failure and smoking (P = 0.021). Conclusion: Zirconia dental implants demonstrated a high long-term success rate of 93.3% over five years. Peri-implant mucositis was the predominant complication, with a relatively low occurrence of peri-implantitis. The findings underscore the potential of zirconia implants for reliable dental implantation. Addressing modifiable risk factors, such as smoking, could further enhance implant success. Continued research is recommended to validate and expand upon these outcomes.

Dental implants are a proven therapeutic option for replacing missing teeth, with positive long-term health outcomes. Dental implant performance is largely determined by the implant’s primary durability, which is affected by surgical procedure, bone quality and quantity, implant surface characteristics, implant geometry, and implant surface characteristics. The implant’s geometry and surface can be modified. The implant geometry and surface can be changed if needed to achieve good primary stability and long-term implant therapy effectiveness. Implant architecture refers to the implant’s three-dimensional structure, as well as all of the components and elements that make it up. Different surface topographies can affect a sequence of coordinated actions such cell proliferation, osteoblast transformation, and the production of bone tissue. At the macro, micro, and increasingly nano sizes, surface topography of implants may be detected. The surgical location of end osseous oral implants is influenced by the prosthetic architecture, as well as the shape and quality of the alveolar bone. There are several alternatives for replacing missing teeth, but within the past few decades, dental implants have been one of the most common biomaterials for replacing one (or more) missing teeth. In a substantial number of patients, titanium dental implants have been shown to be secure and reliable. This study examines the most important historical information of dental implants, as well as the various vital factors that will ensure successful Osseo-integration and a safe prosthesis anchorage.

Nowadays the problem of optimal restorative prosthetics on dental implants is of paramount importance for solving a number of clinically difficult cases and extends beyond the alternative treatment at the complete and partial adentia both on the upper and lower jaws. An essential factor here is understanding of the biomechanical behaviour of the implant-abutment interface, because an optimal implant-abutment interface simulates the biophysical behaviour of natural teeth and ensures the long-term function of the prosthetic restoration. The optimal method for assessing the implant-abutment junction is the static tensile strength method. The limit is determined by performing a single loading of the dental implant in the implant-abutment area.The aim of the study was to assess the implant-abutment deformation of demountable and non-demountable structures of the 4x10 cylindrical and cone-shaped dental implants with determination of their static strength limit.Materials and methods. Two brands of dental implants have been chosen as the objects of research – cylindrical implant LIKO M 4x10 and cone-shaped implant LIKO M DG 4x10. A subject of the research is the ultimate strength of the implant-abutment unit of demountable and non-demountable abutment design.Results. Static loading tests with estimation of the deformation limit of the implant-abutment unit were carried out along with the comparative estimation of the strength of demountable and non-demountable abutment constructions of dental implants of various shapes.Conclusion. The carried out comparative analysis of the static strength makes it possible to optimise the process of prosthodontic treatment on dental implants taking into account the maximal limits of the loaded structures and to carry out the equilibrium load distribution.

Full textAbstract:
Dental implants are frequently used to support fixed or removable dental prostheses to replace missing teeth. The clinical success of titanium dental implants is owed to the exceptional biocompatibility and osseointegration with the bone. Therefore, the enhanced therapeutic effectiveness of dental implants had always been preferred. Several concepts for implant coating and local drug delivery had been developed during the last decades. A drug is generally released by diffusion-controlled, solvent-controlled, and chemical controlled methods. Although a range of surface modifications and coatings (antimicrobial, bioactive, therapeutic drugs) have been explored for dental implants, it is still a long way from designing sophisticated therapeutic implant surfaces to achieve the specific needs of dental patients. The present article reviews various interdisciplinary aspects of surface coatings on dental implants from the perspectives of biomaterials, coatings, drug release, and related therapeutic effects. Additionally, the various types of implant coatings, localized drug release from coatings, and how released agents influence the bone–implant surface interface characteristics are discussed. This paper also highlights several strategies for local drug delivery and their limitations in dental implant coatings as some of these concepts are yet to be applied in clinical settings due to the specific requirements of individual patients.

Full textAbstract:
Micromotion of dental implants may interfere with the process of osseointegration. Using three different types of virtual biomechanical models, varying contact types between implant and bone were simulated, and implant deformation, bone deformation, and stress at the implant-bone interface were recorded under an axial load of 200 N, which reflects a common biting force. Without friction between implant and bone, a symmetric loading situation of the bone with maximum loading and displacement at the apex of the implant was recorded. The addition of threads led to a decrease in loading and displacement at the apical part, but loading and displacement were also observed at the vertical walls of the implants. Introducing friction between implant and bone decreased global displacement. In a force fit situation, load transfer predominantly occurred in the cervical area of the implant. For freshly inserted implants, micromotion was constant along the vertical walls of the implant, whereas, for osseointegrated implants, the distribution of micromotion depended on the location. In the cervical aspect some minor micromotion in the range of 0.75 μm could be found, while at the most apical part almost no relative displacement between implant and bone occurred.

Aim: Dental implant failure might be brought on by an early postoperative infection. The purpose of this study was to assess the prevalence of acute postoperative infection in survived and failed implants and the associated factors. Methods: This cohort cross-sectional study held in the Oral surgery department of Altamash Institute of Dental Medicine, Karachi for two-years duration from January 2021 to December 2022 and evaluate early postoperative infection after dental implant surgery. The location of the implant, the patients' ages and genders, smoking, postoperative antibiotic therapy, bone augmentation and the time of infection development or diagnosis were among the study variables. The study's results showed which implants failed and which survived. Two groups of patients; those who survived implants included in Group A and those who had failed implants were included in group B. Results: Out of 190 patients, 12 (6.3%) patients, including 8 men and 4 women, experienced a postoperative infection after implant insertion. In group A of implant survival, 5 implants (41.7%) acquired post-operative infection while 7 implants (58.3%) in the failed group experience infections. The significant variations among the both groups were noted in terms of the smoker patients, the timing of diagnosis, patients who got bone transplant and fresh socket versus delayed implant placement. Relating to the variables, the Kaplan-Meier analysis revealed that when infection developed 4 days after surgical procedure in subjects not given antibiotic treatment postoperatively, the probability of implant failure increased by 1.1 times (hazard ratio). If the infection developed after six days in people who smoked and after nine days in people who do not smoked and were given antibiotics postoperatively, the likelihood of failure rose. Conclusion: In light of the study's findings, it appears that smoking, early infection, implants placement in newly created sockets, and implants placement in conjunction with bone substitutes may all enhance the failure ratio of dental implants following acute infection. Keywords: antibiotic, implant, infection, and bone

Full textAbstract:
Resonance Frequency Analysis (RFA) is a noninvasive intraoral method designed to assess bone-implant interface and may therefore provide clinical evidence of implant stability. To achieve osseointegration of dental implants, certain biological and biomechanical requirements must be met. One of the most important requirements is the absence of micro-movements during the stage of osseous cicatrization. In classic implant products, implants receive no functional load until bone and implant surface are closely jointed together, as this assures permanent implant stability throughout the stages that follow implant placement.This article discusses the RFA -method for determining the stability of a dental implant of the "Implant.uz" system at various times after dental implantation.

Short dental implants have been successfully used to support single and multiple fixed reconstructions in atrophic jaws, despite an increased crown-to-implant ratio. The use of short dental implants allows the treatment of patients for whom complex surgical techniques cannot be performed for medical, anatomical, or financial reasons. Furthermore, the use of short dental implants in clinical practice reduces morbidity, cost, and treatment time and reduces the need for complex surgery. The aim of this review is to evaluate the survival rates of short and extra-short dental implants and to discuss the impact of an increased crown-to-implant ratio on biologic and technical complications.

Nowadays, dental implants are a prominent therapeutic approach among dentists for replacing missing teeth. Failure in dental implants is a severe challenge recently. The factors which lead to dental implant failure are known. These factors can be categorized into different groups. In this article, we discussed the immunological aspects of implant failure as one of these groups. Cytokines and immune cells have extensive and various functions in peri-implantitis. The equilibrium between pro and anti-inflammatory cytokines and cells, which involve in this orchestra, has a crucial role in implant prognosis. In conclusion, immune cells, especially macrophages and dendritic cells, almost increased in the patients with implant failure. Also, proinflammatory cytokines were proposed as diagnostic factors according to their higher levels in dental implant rejection.

Full textAbstract:
Nowadays the problem of optimal restorative prosthetics on dental implants is of paramount importance for solving a number of clinically difficult cases and extends beyond the alternative treatment at the complete and partial adentia both on the upper and lower jaws. An essential factor here is understanding of the biomechanical behaviour of the implant-abutment interface, because an optimal implant-abutment interface simulates the biophysical behaviour of natural teeth and ensures the long-term function of the prosthetic restoration. The optimal method for assessing the implant-abutment junction is the static tensile strength method. The limit is determined by performing a single loading of the dental implant in the implant-abutment area.
The aim of the study was to assess the implant-abutment deformation of demountable and non-demountable structures of the 4*10 cylindrical and cone-shaped dental implants with determination of their static strength limit.
Materials and methods. Two brands of dental implants have been chosen as the objects of research – cylindrical implant LIKO M 4x10 and cone-shaped implant LIKO M DG 4x10. A subject of the research is the ultimate strength of the implant-abutment unit of demountable and non-dismountable abutment design.
Results. Static loading tests with estimation of the deformation limit of the implant-abutment unit were carried out along with the comparative estimation of the strength of demountable and non-demountable abutment constructions of dental implants of various shapes.
Conclusion. The carried out comparative analysis of the static strength makes it possible to optimise the process of orthopaedic treatment on dental implants taking into account the maximal limits of the loaded structures and to carry out the equilibrium load distribution.

Full textAbstract:
Longitudinal studies have shown that successful implants are colonized by a predominantly Gram-positive, facultative flora, which is established shortly after implantation. Repeated microbiological sampling in patients with clinically stable implants showed no significant shifts in the composition of this flora over five years. In patients with bone loss and pocket formation around implants, however, a significantly different flora was found: Gram-negative anaerobic bacteria, particularly fusobacteria, spirochetes, and black-pigmenting organisms such as Prevotella intermedia were often present in high proportions. Antimicrobial treatment with agents specifically active against anaerobes could halt progression of peri-implant infections in such cases. Although there may be non-microbial primary causes for implant failure, these studies show that Gram-negative anaerobes may play a role in peri-implant infections, and that their elimination leads to improvement of the clinical condition.

Full textAbstract:
Background. With various surgical and prosthetic component designs being introduced in dental implants, decisions have to be made when choosing a system and a certain prosthodontic protocol. A survey of implant prosthodontic specialists has not been previously performed in the Middle East. Aim. This study aimed to determine selection criteria and choice of dental implants and restorations by prosthodontic specialists in the Emirate of Dubai, United Arab Emirates. Materials and Methods. A validated 16-item questionnaire was used in the survey which included demographic information, implant training and experience, implant treatment planning, implant restoration, and implant system preference. The research protocol was approved by the Research and Ethics Committees of Hamdan Bin Mohammed College of Dental Medicine and Dubai Health Authority. Prosthodontists were identified from regulatory authority websites and contacted by e-mail with the questionnaire attached. Results. A total of 84.6% (77) of the registered prosthodontists in Dubai completed the questionnaire with 66.2% reported practicing implant dentistry. Out of which, 54.9% reported surgically placing dental implants and 45.1% restore them only prosthetically. Prefabricated metal abutments were the most commonly selected abutments for single crowns (76.0%) and for fixed dental prostheses (66.7%). Screw retention is preferred mostly for single crowns (68.0%) and fixed dental prostheses (74.0%). Locators were the most commonly selected type of attachment for implant-retained/supported overdentures (49.0%). Conventional loading was the most selected type of loading in all oral conditions. Conclusion. Within the limitations of this study, it can be concluded that most prosthodontists in Dubai practice implant dentistry and more than half surgically place dental implants. Prefabricated metal abutments are the most selected type of abutments. Most prosthodontists use screw-retained implant restorations and prefer locator attachments for implant-retained/supported overdentures. Conventional loading is the most preferred implant loading method in all oral conditions. Implant company/system selections are various and there is no major preference for a certain system. The majority of prosthodontists select implant systems based on implant features, literature review, and simplicity of restorative kit.

Full textAbstract:
Dental implants have become a routine component of daily dental practice and the demand for dental implants is expected to increase significantly in the future. Despite the high success rates of dental implants, failures do occur, resulting in discomfort, rampant destruction of the oral health, or painful and costly surgical replacement of a failed implant. Peri-implant diseases are inflammatory conditions affecting the soft/hard tissues surrounding a functional dental implant. Plenty of experimental evidence indicates that the accumulation of dental plaque at the soft tissue–implant interface and the subsequent local inflammatory response seems to be key in the pathogenesis of the peri-implant mucositis. Such peri-implant–soft tissue interface is less effective than natural teeth in resisting bacterial invasion, enhancing vulnerability to subsequent peri-implant disease. Furthermore, in certain individuals, it will progress to peri-implantitis, resulting in alveolar bone loss and implant failure. Although early diagnosis and accurate identification of risk factors are extremely important to effectively prevent peri-implant diseases, current systematic reviews revealed that a uniform classification and diagnostic methodology for peri-implantitis are lacking. Recent progress on fluorescence-based technology enabled rapid diagnosis of the disease and effective removal of plaques. Here, we briefly review biofilm-associated peri-implant diseases and propose a fluorescence-based approach for more accurate and objective diagnoses. A fluorescence-based diagnosis tool through headlights combined with special-filtered dental loupes may serve as a hands-free solution for both precise diagnosis and effective removal of plaque-biofilms.
