Full textAbstract:
Introduction. A flexible partial denture, as a treatment solution for partial edentulousness, is a current alternative in dental prosthetics, due to simplified design, aesthetic and biomechanical qualities of resin materials, that contribute to the favourable distribution of masticatory forces on the dental and mucosal support. Objective. This study aims to highlight the medical perception of Romanian dentists regarding the evolution of patients treated with flexible partial dentures. Material and method. The research was carried out over a period of two years (2017-2019), on a study group composed of 84 Romanian dentists. Subjects were asked to answer an anonymous questionnaire consisting of 14 closed questions, to outline frequently aspects encountered in practice related to the clinical evolution of the patient rehabilitated with flexible partial removable dentures. Outcomes. Patient comfort (76%) and higher aesthetic properties (54%) were the main reasons why dentists chose a partially flexible prosthetic for the prosthetic treatment of the patient. In the evolution of prosthetic patient, the main problems found at the partial flexible prosthesis were food pigment impregnation of the base (51%) and limited possibilities of repair (34%). Changes in maintenance, support, stability, aesthetic or possible fractures of base and clasps were seen by 46% of respondents, at approximately 1 to 2 years after the application of flexible partial dentures. Conclusions. Flexible partial prosthesis is a method of treatment, whose main advantages are represented by esthetics and superior adaptation of the patients, but because of the deficiencies that occur over time, it is better to be recommended as a provisional treatment solution.

Objectives. To describe dental prosthesis provision in the Brazilian public health service and report the performance of dental prosthesis procedures according to the Brazilian macroregions. Methods. A structured interview was conducted with senior-level health professionals from each of the 18,114 oral health teams (OHT). The dependent variables were performance of removable prostheses and prosthesis procedures, including provision of fixed prostheses by OHT. Descriptive statistics were produced together with performing a cluster analysis using SPSS version 19.0. Results. The manufacture of any type of prosthesis was done by a minority of OHT (43%). The most commonly provided types of dental prosthesis were removable full and partial dentures. Cluster 1 (teams that performed prosthesis procedures the most) was composed of a smaller number of teams (n = 5,531), and Cluster 2 (composed of teams that do not perform prosthetics or that perform them in small amounts) consisted of 12,583 teams. The geographic distribution of clusters reveals that the largest proportion of Cluster 1 teams is located in the Northeast (33.9%) and Southeast (33.6%). Conclusions. A minority of OHT produce dental prostheses. There is an unequal geographical distribution of clusters.

The various treatment options for the aesthetic and functional rehabilitation of partially edentulous patients are conventional fixed partial dentures, implant supported fixed partial dentures and removable partial dentures. In some cases, removable partial dentures may be the only choice which is available other than implants and fixed partial denture. Removable cast partial dentures are used as definitive removable prostheses when indicated, but location of clasps is not aesthetically pleasant. So, when patient is concerned about aesthetics, flexible partial dentures which is aesthetically superior may be considered. But for the success of flexible removable partial denture, proper diagnosis, treatment planning, insertion, wearing and maintenance of this prosthesis is very important.

Full textAbstract:
The basic conditions that ensure good functional qualities and durability of prosthetic structures from the point of view of biomechanics, undoubtedly include an optimal way of fixing a partial removable prosthesis, which consists in the correct choice of the clamping system that ensures reliable fixation of the prosthesis in the given position and at the same time causing a minimum of harm supporting teeth, as well as the most rational distribution of occlusal loads transmitted to the supporting tissues, since it is these factors that determine the durability functioning dentures. The purpose of biomechanical studies is to analyze the stress-strain state of the supporting teeth of partial removable prostheses replacing the included and terminal defects of the dentition when fixing the prosthesis on the supporting teeth with the help of holding and supporting-retaining clamps. The studies were performed on a model of the mandible with overall dimensions of the cross section corresponding to some average dimensions. The first volumetric finite element model was developed to study the stress-strain state of periodontal ligaments of supporting teeth and supporting gingival tissues when the incomplete and bilaterial end defects of the dentition were replaced (1 class 1 subclass by Kennedy) of the mandible by a removable denture with fixation by retaining clamps on the canines and the first premolars. The second volumetric finite element model is designed to study the stress-strain state of periodontal ligaments of supporting teeth and supporting gum tissues when the included and two-sided end defects of the dentition of the lower jaw are replaced by a removable clasp prosthesis with fixation of support-retaining clamps on canines and first premolars with support arms of clamps from the distal sides of premolars. As a result of the studies performed, the following conclusions can be drawn: In both considered variants fixation of removable clasp prostheses loaded with maximum values of equivalent stresses in the periodontium of the supporting teeth is localized at the apex of the alveolar ridge, which indicates the transfer of the "clutching" supporting teeth of the clasp prosthesis. The maximum values f equivalent stresses in the periodontitis of the supporting teeth during fixation of the removable clasp prosthesis by the support-retaining clamps on the canines and the first premolars exceed the corresponding values of the equivalent stresses for the case of fixing the prosthesis with retention clamps by 30-140%! With an increase in gum compliance, the values of equivalent stresses in the periodontitis of the supporting teeth during fixation of the removable clasp prosthesis by the retaining clasps vary insignificantly within 25%, and an increase in the corresponding equivalent stresses with the use of support-holding clasps may be 65%. In order to ensure the maximum sparing regimen of periodontal tissues of supporting teeth and as a result - the possibility of the most prolonged use of the prosthesis without loosening of the supporting teeth, it seems more expedient to give preference to the use of clasp prostheses with the fixation of the retaining clasps.

The main aim of prosthetic dentistry is restoring the form, function, comfort and appearance of the patient by the placement of a prosthesis replacing the missing teeth and contiguous tissues.1 Various prosthetic options for partially edentulous patients include an interim removable partial denture (RPD) to a cast partial denture, a fixed dental prosthesis (FDP), and a more implant-retained prosthesis. However, FDP and implant-retained prosthesis are not always feasible, particularly in patients with excessive residual ridge resorption and jaw defects due to trauma and / or surgical ablation. In such a situation, a dentist may resort to another option of fixed-RPD prosthesis, to restore the defective hard and soft tissues to achieve natural aesthetics, phonetics, comfort, and better hygiene. This hybrid prosthesis fulfils the objectives of the rehabilitation such as support, stability, and retention characteristics similar to a fixed prosthesis and aesthetics and hygiene maintenance of a removable prosthesis.2,3,4,5 Any prosthesis designed or fabricated should be based on the prosthetic principles of support, stability, retention, and preservation of remaining structures.1 From the patient's perspective, retention is one of the important factors for its acceptability. These retentive options range from simple bar and clip attachments to more sophisticated spark erosion overdentures.6,7 Spark erosion prosthesis is technique sensitive, bulky, and requires expensive equipment.6,7 On the other hand, precision attachments provide better vertical support and stimulation to the underlying tissue through intermittent vertical massage.8 Treatment with a hybrid denture is an affordable choice to fulfil the patient's aesthetic demands along with providing a good prognosis for the prosthesis and preservation of the remaining dentition. This article presents two case reports of prosthodontic rehabilitation of a patient with mandibular defects using an attachment-retained fixed-removable hybrid prosthesis.

BACKGROUND: The morphology of the retention tooth often does not correspond with the required design; hence there is often an indication for enamel recontouring or other restorative procedures.AIM: The study aimed to determine the impact of changing the path of insertion of the prosthesis by reshaping the anatomical and morphological structures of the natural teeth predetermined for the retention of the prosthesis.MATERIAL AND METHODS: The group of 40 patients with Class II, Subclass 1 according to Kennedy was formed, and 120 approximal surfaces of retention teeth were obtained. Two different types of prostheses were made on the models: one group in the zero point position of the model, and another group in the zero position of the model, with changing of the direction of input at an angle of 2˚.RESULTS: The difference between the established and theoretical normal distribution of frequencies was tested with the Kolmogorov-Smirnov and Lilliefors tests (r < 0.10; r < 0.01). The first group showed a retention force of 0.08 N. In the second group the retention force was 0.94 N.CONCLUSION: It could be concluded that the change in the path of insertion of the dental prosthesis with conservative restorations as composite inlays, as well as the accurate extension of the prosthesis onto guiding plane surfaces, will undoubtedly increase the retention force of the prosthesis.

Purpose: This work aims to present a methodology developed for dimensional analysis of removable partial dentures, following a route with a model manufactured by additive manufacture and a further casting process of a Co-Cr alloy part. Design/methodology/approach: The method for designing and manufacturing removable partial dentures (RPD) is focused on their completely virtual design. They are manufactured with resin additive manufacturing chrome-cobalt cast alloys. A 3D image correlation scanner was used for dimensional and geometrical tolerance analysis. Findings: The prostheses manufactured by CAD-CAM route are more accurate than conventional ones, but they suffer distortion during the casting process. This distortion did not interfere with the patient's well-being or with the adaptation to the prosthesis. Research limitations/implications: The technique presented herein paper allows preparing better fitting prosthesis. Providing the best comfort and masticatory power. Practical implications: Improving the precision in the manufacturing process of a removable partial denture is very important for professional dentists and their patients. Originality/value: The proposed technique and the work approach provide the prosthesis preparation with shorter ambulatory time in addition to greater comfort to the patient.

Improvements in oral health including increased retention of natural teeth have given rise to a partially dentate older population. Replacement of missing natural teeth is important to improve function, aesthetics and quality of life for this patient group. A variety of options are available to replace missing teeth in partially dentate older adults, including fixed, removable and implant retained prostheses. This article will discuss the provision of removable partial dentures including treatment planning and denture design. When planning removable partial dentures, careful attention must be paid to stabilising the patient prior to delivering any prosthesis. Partial dentures should be designed to minimise the potential for plaque accumulation with carefully designed metal based frameworks. Acrylic resin can also be utilised with attention to detail to minimise the risk of damage to delicate supporting tissues. Removable dentures have the advantage that they can be readily added to in the event of further tooth loss which may be particularly relevant for older adults. Partial dentures which optimise support, retention and stability can function very successfully and significantly improve patients’ oral health related quality of life.

ABSTRACT A 66-year-old man visited our department with the chief complaint of poor esthetics due to loss of a fixed partial denture in a maxillary incisor tooth and difficulty in mastication due to an ill-fitting, mandibular removable partial denture. An analysis of the occlusal vertical dimension resulted in a diagnosis of infraocclusion. After increasing vertical dimension with a provisional restoration and treatment denture which covered the attritioned surface, a definitive prosthesis was applied. Untreated loss of molars and severe attrition of the remaining teeth caused infraocclusion in this patient, which increased occlusal loading on the incisor teeth and induced detachment of the prosthesis in the maxillary incisors. Esthetic appearance was improved and masticatory dysfunction restored by increasing vertical dimension and oral rehabilitation. Mildly invasive prosthetic treatment involved application of a removable partial denture which covered the attritioned surface, not only infraocclusion but masticatory dysfunction and poor esthetics were also treated.

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.

Most removable partial denture (RPD) wearers are satisfied with their prostheses, but the factors that influence satisfaction and acceptance are still not determined. OBJECTIVE: This study explored technical, biological, and satisfaction variables for the functioning of RPDs after five years, and compared the evaluation by the patient and by the clinician. MATERIAL AND METHODS: Fifty adults (39 females, 11 males) were re-examined after five years of RPD service. Data were collected through clinical examination and a structured questionnaire to record the conditions of supporting soft tissues, prosthesis acceptance and technical characteristics, mastication, esthetics, comfort, hygiene, and need for professional intervention. Data were analyzed by descriptive statistics and Spearman correlation. RESULTS: More than 50% of patients classified their RPDs as excellent regarding retention, mastication, esthetics, comfort, and hygiene. In the professional evaluation, retention and stability were considered excellent in more than 66% of cases, and hygiene of teeth and prostheses was considered good in 52% and 46%, respectively. The metallic framework and acrylic base were considered adapted in 92% of cases. Prosthesis acceptance was associated with retention, mastication, esthetics, hygiene, and comfort evaluated by the patient, and with retention, stability, and condition of the framework evaluated by the clinician. Retention and mastication/comfort evaluated by the patient had moderate positive correlation with retention and stability measured by the clinician. There was no association of hygiene evaluation by the patient and by the clinician. CONCLUSIONS: After five years, the oral rehabilitation with RPDs was satisfactory for most cases. There was correspondence between retention/retention and mastication-comfort/stability variables evaluated by the patient and by the clinician. Oral and prosthesis hygiene were not related.

Despite the achievements in medical rehabilitation of patients with partial and complete absence of teeth, rehabilitation is not a definitely settled issue for orthopedic dentistry. According to the World Health Organization, about 26% of patients do not use full dentures for various reasons. The most common reasons for non-adaptive removable dentures are poor denture fixation or pain under prosthesis, which may be associated with the development of prosthetic stomatitis. We elaborated a method for the prevention and treatment of prosthetic stomatitis (toxic and allergic), using the magnetron coating with fullerene C60 surface of the prosthesis base.
 The aim of the research is the study of bioelectric activity of the masseter muscle in patients with manifestations of intolerance to acrylic base plastic after covering the prosthesis base with C60 fullerene in the observation period of up to 3 months.
 Material and methods of the research. We examined 29 subjects who presented to the orthopedic dentistry clinic for restoration of dentitions, using of partial and full laminar removable dentures. Patients were divided into 3 groups. The first group embraced patients with complete dentitions without dentures (9 people). The second group comprised patients who used partial and complete removable dentures with acrylic base for 1-3 months and they were diagnosed with prosthetic stomatitis (10 people). The third group included patients, implanted with partial and complete laminar removable dentures with the phenomena of prosthetic stomatitis, which underwent isolation of the prosthesis base using magnetron nano-coating with C60 fullerene (10 people).
 The functional state of the masseter muscles was determined by superficial electromyography, taking into account the condition of the prosthetic bed tissues and the period of using the dentures with nano-coating for 1 day, 15 days, 30 days and 2 months after denture placement.
 Results of the studies and their discussion. As shown by our studies, patients who used partial and complete removable prostheses with symptoms of prosthetic stomatitis (toxic and allergic stomatitis) demonstrated a significant effect on the bioelectric activity of the proper masseter muscles as compared with patients in group 1. The average amplitude of volitional compression was less at 2.8 times and the average amplitude of arbitrary chewing was less at 2.1 times, the dynamics of the states of rest and activity of chewing muscles was impaired. A reduction in the activity time and a slight increase in the resting time both on the working side and on the balancing side, as compared to patients in group 2 were observed in the first day after prosthetics with magnetron C60 fullerene nano-coating. Patients in group 3 demonstrated an increase in bioelectric activity (the amplitude of biopotentials increased), as compared with group 2, both in volitional compression and in arbitrary chewing. On the 15th day of observation, the electromyographic pattern in patients of group 3 changed and was characterized by a pronounced tendency to normalized indicators of the activity and rest time. The electromyogram amplitude of the masseter muscles increased significantly, but at this time the observations did not reach the values of group 1. One month after applying the dentures, electromyograms of patients demonstrated a more pronounced alternation of activity waves with periods of rest, the amplitude of biopotentials oscillation increases. One month after denture placement, the indicators of group 3 approached the data, obtained in patients of group 1. After conducting the electromyographic study within 3 months, we found that in group 3, the values of average amplitude of arbitrary chewing and the amplitude of volitional compression of the masseter muscles were 2 times higher than those of group 2. The time of activity and rest became more balanced and did not differ significantly from indicators in group 1.

INTRODUCTION: The difficulty in accessing oral health services and the practice of dental mutilation has led to a high number of individuals affected by edentulism. In order to reverse this situation, the National Oral Health Policy was implemented and with it the Dental Prosthesis Laboratories. OBJECTIVE: To evaluate the productivity of the dental prothesis of these laboratories in the state of Bahia, in 2016. METHODOLOGY: This was a quantitative-descriptive study in which data were collected from Outpatient Information System of the Unified Health System regarding dental prosthesis productivity. The information of physical structure, human resources of the laboratories and their distribution by health regions were collected in the site of the National Registry of Health and other information about the municipality in the Brazilian Institute of Geography and Statistics. The absolute and relative frequency of the variables and the comparison of productivity with the structural characteristics of the laboratories and health regions of Bahia were presented. RESULTS: We analyzed 51 municipalities that offer dental prosthesis services in SUS, of these 32 have CEO. A total of 46,870 prostheses produced of the type dentures, partial removable, fixed and on implant were observed, with the cities with CEO producing 66.49% and the 19 cities without CEO produced 33.51%. The type of prosthesis most performed was the total (58.73%) followed by the removable partial prosthesis (40.07%). The South region presented the highest productivity of dental prostheses (24.26%) while the region Center North produced the lowest amount (2.28%). CONCLUSION: Although there is a considerable amount of prostheses produced, only 12.2% of the municipalities in Bahia have a dental prosthesis laboratory, even demonstrating a considerable amount of productivity.

Tooth loss is a common dental problem. Impairment of oral functions and masticatory efficiency is a result of tooth loss. The negative effects of tooth loss can be managed by the fixed and removable prosthesis. This study was conducted to determine the influence of gender in selecting prosthesis. This study was a retrospective observational study conducted in a university hospital in Chennai. Data collection was done with the help of the electronic dental record of the university- Dental information archiving software (DIAS). It records all patients data from initial visit to last visit chronologically. This was followed by Excel tabulation. Data was analysed using SPSS Software. The association of study variables was calculated using the Chi-Square test. Within the limits of the study, female patients were willing for replacement of teeth than male patients (55%). There was a significant difference in choosing the type of prosthetic treatment. It was seen that fixed partial denture was chosen over removable prosthesis (59.8%).

Full textAbstract:
Oral rehabilitation of partially edentulous arches requires careful treatment planning before any prosthodontic intervention. The connection of the metal framework of fixed (fixed dental prosthesis (FPD)) and removable partial denture using adhesive attachments is a good alternative prosthetic option when solely fixed prosthesis (FPD or implant) cannot be used due to anatomical limitation. Attachments are the tiny interlocking devices that act as a hybrid link to join removable prosthesis to the abutment and direct the masticatory forces along the long axis of the abutment. This joint acts as a non-rigid stress breaker, which helps in distributing the occlusal load. Precision and semiprecision attachment have always been bordered by an aura of mystery due to technique sensitive procedure and lack of knowledge. The following case describes a combined contemporary and conventional approach and treatment sequence with the use of attachments for the rehabilitation of partially edentulous arches.

Removable partial denture is a repulsive modality of treatment that we still must rely upon for certain cases and is a part of the practice. But these patients expect it to look as esthetic as any other contemporary modality of treatment. This article thus focuses on the esthetic aspects that a clinician must place emphasis upon during the designing and fabrication of prosthesis to provide the desirable outcome.Kathmandu Univ Med J 2013; 11(4): 344-348

Full textAbstract:
The aim of this systematic review was to evaluate the functionality of fixed and removable partial dentures as test interventions in relation to variations in the opposing dentition and their prosthetic restoration. The abstracts identified in the respective databases were screened independently by two investigators. RCTs and uncontrolled studies were considered, provided the patients were included consecutively and the confounding variables were adequately monitored. Seventeen papers were included. The study and publication quality was assessed using a “biometric quality” tool showing an overall poor quality. The reported outcomes, such as survival rates, were in each case obtained from a single study. Two possible trends could be deduced for the endpoint longevity: (a) the first trend in favor of removable partial dentures, compared to fixed partial dentures, with a fully edentulous opposing arch fitted with a removable prosthesis; (b) the second trend in favor of implant-supported partial dentures, compared to conventionally fixed partial dentures, with natural opposing dentition or with a removable partial denture in the opposing arch. No evidence could be generated as to whether, and if so how, variations in the opposing dentition have a bearing on the decision to fit a partially edentulous arch with a fixed or removable partial denture.

This study examined the prevalence of self-perceived chewing discomfort depending on the type of dental prosthesis used in South Korean adults. The subjects were 12,802 people over 20 years of age who participated in a health interview and dental examination. Chewing discomfort was examined using a self-assessed report with a structured questionnaire. Using multivariable logistic regression analysis, adjusted odds ratios were evaluated along with their 95% confidence intervals (α = 0.05). After adjusting for covariates, including age, gender, smoking, drinking, hypertension, diabetes, body mass index, education, income, and toothbrushing frequency, the odds ratios (95% confidence intervals) for chewing discomfort in groups without a dental prosthesis, with fixed dental prostheses, with removable partial dentures, and with removable complete dentures were 1 (reference), 1.363 (1.213–1.532), 2.275 (1.879–2.753), and 2.483 (1.929–3.197), respectively. The association between the prevalence of chewing discomfort and the type of dental prosthesis used was statistically significant even after adjusting for various confounders (p < 0.0001). The type of dental prosthesis was related to chewing discomfort among South Korean adults.

ABSTRACTFor patients with shortened dental arches, many treatment options are available. The existing situation can be maintained by stabilizing the present dentition and improving the occlusion without extending the arch. Alternatively, the shortened dental arch can be extended by either a free-end saddle removable partial denture, cantilevered fixed bridge, or by an implant-supported prosthesis. The free-end saddle removable partial denture can be considered a simple, non-invasive, and relatively cheap treatment option for the shortened dental arch. It was believed that such prosthodontic rehabilitation would be beneficial for the patients in terms of improving oral functions. However, the existing literature indicates that the prognosis of free-end saddle removable partial denture is not predictable, it is problematic, and its contribution to oral functions in patients with shortened dental arches is considered to be dubious. This paper reviews and summarizes the current literature about the outcome of extending the shortened dental arch by a free-end saddle removable partial denture. It also outlines factors that may affect the prognosis of this prosthetic treatment.

ABSTRACT Aim Surgical removal of tumors in the mandible leads to discontinuity of bone which requires surgical reconstruction of the defect to provide a suitable tissue foundation for an acceptable prosthesis. At times when reconstructive surgeries are not possible, prosthetic rehabilitation is a successful alternative. In the present article, prosthetic rehabilitation using neutral zone technique has been discussed in the patient of marginal mandibulectomy. Methods The fabrication procedure of the removable partial denture was modified to achieve adequate retention and stability in a 22-year-old female patient with the anterior mandibulectomy. Polished surface contours and tooth positioning were recorded with modified neutral zone technique and mandibular teeth were characterized to provide esthetics. Conclusion The modified neutral zone technique enhanced the stability of the partial denture. A marked improvement in esthetics, function and psychology was noticed.

Use of attachment in providing retention to removable prosthesis is an old treatment modality with better success. It highly improves the comfort, aesthetic, function, and patient satisfaction, especially in the patients with long span edentulism where implants and fixed partial denture (FPD) are not indicated and cast partial dentures are barely satisfactory. Proper diagnosis and treatment planning is necessary for selection of appropriate attachment type. A comprehensive evaluation, multi-disciplinary approach and sequential treatment planning is needed for long-term successful outcome. This case report describes the use of an extra coronal semi-precision attachment to enhance retention of removable prosthesis.

Background: Losing posterior teeth for a long time would occasionally lead to the sharpening of alveolar process. The removable partial denture usually have problems when used during mastication, because of the pressure on the mucosa under the alveolar ridge. Purpose: The purpose of this case report was to manage patients with sharp mandibular alveolar process by wearing hybrid prosthesis with extra coronal precision attachment retention and soft liner on the surface base beneath the removable partial denture. Case: A 76 years old woman visited the Prosthodontic Clinic Faculty of Dentistry Airlangga University. The patient had a long span bridge on the upper jaw and a free end acrylic removable partial denture on the lower jaw. She was having problems with mastication. The patient did not wear her lower denture because of the discomfort with it during mastication. Hence, she would like to replace it with a new removable partial denture. Case management: The patient was treated by wearing a hybrid prosthesis with extra coronal precision attachment on the lower jaw. Soft liner was applied on the surface of the removable partial denture. Hybrid prosthesis is a complex denture consisting of removable partial denture and fixed bridge. Conclusion: It concluded that after restoration, the patient had no problems with sharp alveolar process with her new denture, and she was able to masticate well.Latar belakang: Kehilangan geligi posterior dapat menimbulkan processus alveolaris tajam.

Prosthodontic rehabilitation can be accomplished with fixed, overdenture, complete, or implant-retained prostheses. Dental treatment overcomes the patient’s functional, psychological, esthetic and phonation problems. Remaining healthy teeth may allow the dentist to fabrícate a removable partial overdenture, fixed partial prosthesis or implant - supported prosthesis. The retention of a number of abutments helps maintain a positive ridge form with greater height and volume of the alveolar bone, improving masticatory performance, as well as providing a more stable prostheses. Dental patients who have medical problems need many treatment procedures. Multidisciplinary treatment planning is invaluable for patient’s dental health. Progeria is a rare genetic condition where symptoms resembling aspects of aging are manifested at an early age. characteristic clinical findings of Progeria disease include abnormalities of the skin and hair in conjunction with char-acteristic facial features and skeletal abnormalities. The characteristic facies show protruding ears, beaked nose, thin lips with centrofacial cyanosis, prominent eyes, frontal and parietal bossing with pseudohydrocephaly, midface hypoplasia with micrognathia and large anterior fontanel. The other reported anomalies are dystrophic nails, hypertrophic scars and hypoplastic nipples. The findings that are nearly interested in dentistry are delayed dentition, anodontia, hypodontia, or crowding of teeth. This article presents the multidisciplinary dental treatment planning includes surgical, endodontic and prosthetic treatment of a patient with a history of progeria. In this case complete-arch fixed prostheses in both maxilla and mandible, supported by a combination of im-plants and teeth are reported.

In the elderly and senile age, the need for medical care, including dental care, is increasing. The untimely appeal for dental care entails a change in the KPI index, as a result of which a partial or complete loss of teeth occurs. Complete absence of teeth is accompanied by morphofunctional changes of all elements of the dentoalveolar system, a significant decrease in chewing ability. Providing orthopedic dental care to the population of elderly, senile and old age is not easy due to the peculiarities of adaptation to removable dentures. In this study, the impact of removable dentures on the quality of life of a dental patient was assessed. The study involved 217 people aged 75 to 95 years. All patients needed removable prosthetics. Before the prosthetics, a questionnaire was conducted using the OHIP-14 questionnaire. The questionnaire showed the level of satisfaction with their dental health of the patients being examined. Then proceed to prosthetics. In the first group, the prosthesis was manufactured using a standard method. In the second group, the impression was removed using a modified individual spoon, which should improve adaptation to a removable denture. One month after the prosthesis, when all patients had complete adaptation to a removable denture, a second questionnaire was conducted using the OHIP-14 questionnaire. In order to reveal the dynamics of the quality of life of the patients being examined. The results showed the effectiveness of the proposed method. The number of patients with a good standard of living in group 2 increased by 58.8%, and in group 1 only by 34.5%. In group 2, adaptation to removable dentures was more rapid.

The present study was aimed at reviewing the studies that used finite element analysis (FEA) to estimate the biomechanical stress arising in removable partial dentures (RPDs) and how to optimize it. A literature survey was conducted for the English full-text articles, which used only FEA to estimate the stress developed in RPDs from Jan 2000 to May 2021. In RPDs, the retaining and supporting structures are subjected to dynamic loads during insertion and removal of the prosthesis as well as during function. The majority of stresses in free-end saddle (FES) RPDs are concentrated in the shoulder of the clasp, the horizontal curvature of the gingival approaching clasp, and the part of the major connector next to terminal abutments. Clasps fabricated from flexible materials were beneficial to eliminate the stress in the abutment, while rigid materials were preferred for major connectors to eliminate the displacement of the prosthesis. In implant-assisted RPD, the implant receive the majority of the load, thereby reducing the stress on the abutment and reducing the displacement of the prosthesis. The amount of stress in the implant decreases with zero or minimal angulation, using long and wide implants, and when the implants are placed in the first molar area.

Relevance: the search for ways to improve the efficiency of dental orthopedic rehabilitation of patients with dentition defects is relevant. Most people with overweight and obesity over 45 years old with a high incidence of pathology in the form of partial absence of teeth. Reducing the effectiveness of chewing, taking highly carbohydrate foods contribute to an increase in the growth of plaque, the intensity of the carious process and the deterioration of hygienic indicators of the mouth.Purpose – to assess the hygienic condition of the oral cavity in patients with an excess of body mass index after orthopedic treatment with removable prostheses.Materials and methods: the survey was conducted to 57 individuals with excess body mass index (BMI): overweight and obesity at various times after the manufacture of partial removable laminar dentures after 1 month, 3 and 6 months after prosthetics. The dental formula, dentition classification in Kennedy’s modification and mucosa according to Supple, the presence of periodontal diseases, dental indexes were determined by the simplified hygiene index of the oral cavity ОНJ-S (Oral Hygiene Index Simple) and the gingivitis index GI (Gingivitis Index).Results: When using removable dentures, indicators of oral hygiene indices sharply deteriorated. After the first month of wearing prostheses, the ONJ-S Green index increased by one third, after 3 months and 6 months, it worsened over the period of observation of patients. The Silnes–Low Index increased 1.5 times after a month of wearing a prosthesis, after 3 months – almost 2 times, after 6 months – 3.7 times, which corresponded to moderate gingivitis.Conclusion: studies have shown that overweight, obese people using removable dentures after prosthetics showed a deterioration in the index indicators – OHJ-S and Silnes–Low in the dynamics during the observation period for patients.

<p>Deficiencies in the alveolar ridge, dental migration and malocclusion are conditions that may hamper restorative treatment and thus must be resolved by taking a multidisciplinary approach. This clinical case report is associated with orthodontics, implantology and prostheses for rehabilitation. A 34-year-old male patient presented himself in a private practice complaining of aesthetics and discomfort when chewing. At the clinical examination, teeth numbers 11, 12, 21, 22 and 25 were absent, with a removable partial denture replacing them. Due to the prolonged use of this prosthesis, wear of the artificial teeth and the extrusion of the anterior inferior teeth were present. A depression was also present in the vestibular region of the upper incisors, which did not provide adequate lip support. The tomographic examination revealed that despite the deficiency of the vestibular-lingual bone volume, the remnant in this region allowed for the implantation of implants. Orthodontic treatment was performed for the intrusion of the inferior elements and the alignment of the arches, with the goal of providing more spaces for rehabilitation. Afterward, the patient underwent surgery to install implants in the 11, 21 and 25 regions, concomitantly with bone regeneration in the vestibular region of the upper incisors. During this time, the patient used a new removable partial denture. After eight months, the prosthetic phase was started. Ten years after the end of treatment, the patient is satisfied with the results and performs maintenance every six months.</p><p><strong>Keywords</strong></p><p>Tooth movement techniques; Dental implants; Bone transplantation; Dental prosthesis.</p>

Background: Distal extension edentulism can affect the patients ability to function as a dentate person. A well-made removable partial denture that has appropriate extensions, borders and ridge-to-dentition relationship will benefit the partially edentulous patient by providing increased comfort and improved dental function. This article described a patient who had a bilateral distal extension removable partial denture in both upper and lower arch. The prosthesis showed a successful rehabilitation with proper function and aesthetics. Methods: A Kennedy class I bilateral free end saddle edentulous arch in both upper and lower arch was rehabilitated with removable cast partial denture. The case had the reasonable amount of crown: root ratio for the remaining abutment teeth for placement of metal framework, occlusal rest and cast clasp. Results: The delivered denture showed proper sitting of occlusal rest and cast clasp. Retention and stability was acceptable. Occlusion had achieved its desired occlusion scheme. Conclusion: Removable cast partial denture is a suitable option for the rehabilitation of partially edentulous case if the case has such amount of abutment teeth remaining with healthy periodontal condition.

Full textAbstract:
ABSTRACT It has been well documented that anterior ridge defects present in a patient are very difficult to treat properly. These defects have been treated with great amount of planning and complexities while using the conventional treatment approaches like removable or fixed prosthesis and options of implant. Though totally implant-supported restorations are very successful, dentists may resort to prescribe implant overdentures because of functional, anatomical economical or esthetic considerations. However, the loading conditions of the partially implant- supported overdenture may affect the long-term predictability of this type of restoration. The concept of the Andrew's bar system can be utilized. In some cases the Andrew's bar system is superior to the implant-supported fixed partial denture and other techniques for implant overdentures. The purpose of this article is to evaluate and describe the Andrew's bar system (a fixed removable partial denture), to treat a class III anterior ridge defect using natural teeth as abutments for its fixed component followed a removable component. The use of Andrew's bar system over implants offered the dentist another option in meeting patient's needs.

Full textAbstract:
Removable prosthesis is considered as a device with therapeutic, rehab and prophylactic functions, which allows to improve the quality of life of the dentist. Its use is always aimed at solving three problems: restoration of chewing; restoration of pronunciation of sounds; restoration of aesthetic norms of a person.
 Fixation of the complete removable denture depends on the anatomical retention, which is determined by the area and form of the prosthetic bed; from adhesion (capillary forces, viscosity of saliva) and from the functional suction of the prosthesis. For the stabilization of prostheses, the contour of the alveolar appendix and the production of artificial teeth are of special importance.
 Therefore, a complete removable denture is a complex design, which always has a single plan of construction (basis and artificial teeth), but in each case is made taking into account the individual characteristics of the patient's body.
 Adaptation to a complete removable denture is a multi-layered process. Its inalienable component is neuro-reflex mechanisms. From these positions, the habit of prosthetics is explained by the development of cortical inhibition, which leads to the disappearance of the feeling of a foreign subject in the oral cavity. These changes occur on the basis of the general law, according to which repeatedly the stimulus becomes a brake agent. Based on masticatography, it has been established that addiction to prosthetics is associated with the appearance, perfection and consolidation of new conditioned motor reflexes. An important component of the adaptation process in patients with prosthetics is psychological adaptation. It is believed that it represents the sum of complex conditioned-reflex responses of the patient, which belong to the sphere of human emotions and determine the degree of satisfaction with dentures. The significance of psychological factors in the development of adaptation to prosthetics stimulates the creation of new and improved existing methods for assessing the psycho-emotional state of orthopedic dental patients. According to the results of these methods, high personal anxiety is the main factor that causes the development of psycho-emotional stress during orthopedic treatment.
 There is also a speech adaptation, which is the result of the interaction of the active organs of the articulation apparatus with dentures. The appearance of improper pronunciation of sounds is considered as a result of motor and sensory disorders of the central or peripheral nature: changes in the structure of the articulation apparatus and violations of muscle inertia involved in articulation; reduction of peripheral hearing and violations of the auditory perception of the central character. Wrong pronunciation is most often observed in groups of whistling, silent sounds, [p], [l], which are characterized by complexity of sounding and, accordingly, the complexity of articulation work. A certain range of works is devoted to methods of studying pronunciation of sounds from different points of view: physical (acoustic), anatomical-physiological and linguistic.
 Detection of defects of articulation was done by listening. In a number of studies the study of violations of articulation of sounds was carried out using anatomical-physiological and acoustic characteristics with the help of apparatus. Modern methods of speech research are based on listening, audiometry and spectral analysis of sound.
 Consequently, the features of rehabilitation of toothless patients with the help of a complete removable denture are widely covered in the literature. The concept of pathogenesis of violations with full or partial adentia and about mechanisms of their overcoming with the help of dentures is deepened. However, until now, the literature remains almost uninvolved into the consideration of phonetic aspects as in the analysis of anatomical and physiological features of the toothless mouth during preparation for prosthetics, and at different stages of the use of dentures.
