Abstract:
Introduction: Dental implants are increasingly used to restore missing dentition. These titanium implants are surgically installed in the edentulous alveolar ridge and allowed to osteointegrate with the bone during the healing phase. After osseo-integration, the implant is loaded with a prosthesis to replace the missing tooth. Conventional implant treatment planning uses study models, wax-ups and panoramic x-rays to prefabricate surgical stent to guide the preparation of the implant site. The drilling into the alveolar ridge is invariably a “blind” procedureas the part of the drill in bone is not visible. Stereotactic systems were first introduced into neurosurgery in 1986. Since then, computer-assisted navigational technology has brought major advances to neuro-, midface and orthopaedic surgeries, and more recently, to implant placement. Clinical Feature: This paper illustrates the use of real-time computer-guided navigational technology in enhancing safety in implant surgical procedures. Outcome and Conclusion: Real-time computer-guided navigational technology enhances accuracy and precision of the surgical procedure, minimises complications and facilitates surgery in challenging anatomical locations.

Abstract:
This retrospective analysis was undertaken to evaluate the effect of immediate implant restoration using a computer-assisted technique in partially edentulous sites on interimplant and intertooth bone level stability and papilla formation. Nine partially edentulous patients received a total of 23 implants that supported immediately placed implant restorations. Planning was accomplished using a radiographic guide, which allowed visualization of the emergence profile from the platform of the implant to the cervical of the planned restoration. Guided implants were placed according to the manufacturer's instructions, and restorations were screw retained directly to the implant. Multiple implants were splinted at surgery with autopolymerizing resin. Measurements were made at a mean of 545 days (range 288–958) postoperatively on the basis of radiographs and photographs. Measures were: (1) distance from bone crest to platform, (2) bone crest to contact point, (3) interimplant distance at the outer diameter of the platform, and (4) papilla from highest point to a reference line. At follow-up time, the bone ridge was located higher than the implant platform (mean 0.57 mm) compared to implants whose interimplant distance was less than 3 mm (mean 0.27 mm). Mean increase of the bone level between insertion and approximate 1-year follow-up was 0.047 mm. The mean distance from the contact point to bone was 2.39/3.93 mm postoperatively, resulting in 91/71% papilla fill between implants and between implant and adjacent tooth, respectively. Computer-assisted surgery with the preplanned immediate restoration seems to be an effective method to minimize bone loss at the implant platform resulting in support for papilla.

Abstract:
Compared to traditional implant surgical guides, computer-assisted implant surgical guides can be considered for positioning implants in the final prosthesis. These computer-assisted implant surgical guides can be easily fabricated with personal 3D printers after being designed with implant planning CAD software. Although the accuracy of computer-assisted implant surgical guides fabricated using personal 3D printers is an important factor in their clinical use, there is still a lack of research examining their accuracy. Therefore, this study evaluated the accuracy of computer-assisted implant surgical guides, which were designed using two implant planning CAD software programs (Deltanine and R2gate software) and fabricated with personal 3D printers using a non-radiographic method. Amongst the patients who visited Kyungpook National University Dental Hospital, one patient scheduled to undergo surgery of the left mandibular second premolar was randomly selected. Twenty partially edentulous resin study models were produced using a 3D printer. Using the Deltanine and R2gate implant planning CAD software, 10 implant surgical guides per software were designed and produced using a personal 3D printer. The implants (SIII SA (Ø 4.0, L = 10 mm), Osstem, Busan, Korea) were placed by one skilled investigator using the computer-assisted implant surgical guides. To confirm the position of the actual implant fixture, the study models with the implant fixtures were scanned with a connected scan body to extract the STL files, and then overlapped with the scanned file by connecting the scan body-implant fixture complex. As a result, the mean apical deviation of the Deltanine and R2gate software was 0.603 ± 0.19 mm and 0.609 ± 0.18 mm, while the mean angular deviation was 1.97 ± 0.84° and 1.92 ± 0.52°, respectively. There was no significant difference between the two software programs (p > 0.05). Thus, the accuracy of the personal 3D printing implant surgical guides is in the average range allowed by the dental clinician.

Abstract:
In this paper, we investigate a motion-tracking system for robotic computer-assisted implant surgery. Failure of the accurate implant positioning may result in significant problems, thus an accurate real-time motion-tracking system is crucial for avoiding these issues in computer-assisted implant surgery. Essential features of the motion-tracking system are analyzed and classified into four categories: workspace, sampling rate, accuracy, and back-drivability. Based on this analysis, requirements for each category have been derived to ensure that the motion-tracking system meets the desired performance criteria. A novel 6-DOF motion-tracking system is proposed which demonstrates high accuracy and back-drivability, making it suitable for use in computer-assisted implant surgery. The results of the experiments confirm the effectiveness of the proposed system in achieving the essential features required for a motion-tracking system in robotic computer-assisted implant surgery.

Abstract:
Dental implants have been placed millions of times worldwide, and the surgical procedure and implant design have steadily improved. The basic prosthetic connection, which makes use of an abutment, has changed little over the past decades. These days, implant placement with immediate provisionalization is an essential stage in implant dentistry and interdisciplinary treatment strategies. Temporary computer-aided design and computer-aided manufacturing (CAD/CAM) of implant-supported crowns restore esthetics and guarantee function during the restoration process and the osseointegration of the dental implant. This case report describes the digital planning; the immediate, static, computer-assisted implant surgery, and the immediate chairside provisionalization of a novel implant system that is directly screw-retained without an abutment.

Abstract:
Purpose. Computer-assisted stereolithographically guided surgery allows an ideal implant placement for prosthetic restoration. Two types of stereolithographic templates are currently available: a fully guided template and a pilot-drill guided template. The purpose of this study was (i) to evaluate the accuracy of implant insertion using these types of surgical templates and (ii) to define parameters influencing accuracy. Materials and Methods. 20 patients were enrolled and divided into 2 study groups: in group A, implants were placed using CAD-CAM templates with fully guided sleeves; in group B, implants were placed with a template with only pilot-drill guided sleeves. Pre- and postoperative computed tomographies were used to measure differences between final positions of implants and virtually planned positions. Three linear discrepancies (coronal, apical, and depth) and two angular ones (buccolingual and mesiodistal) were measured. Correlations between accuracy and jaws of interest, implant length and diameters, and type of edentulism were also analysed. Results. A total of 50 implants were inserted in 15 patients using CAD-CAM templates: 23 implants in group A and 27 in group B. The mean coronal deviations were 1.16 and 1.11 mm (P = 0.35), respectively; the mean apical deviations were 1.65 and 1.71 mm (P = 0.22); the mean depth deviations were 0.95 and −0.68 mm (P = 0.032); the mean buccolingual angular deviations were 4.16° and 6.72° (P = 0.042); and the mean mesiodistal ones were 2.81° and 5.61° (P = 0.029). In addition, the accuracy was statistically influenced only by implant diameter for coronal discrepancy (P = 0.035) and by jaw of interest for mesiodistal angulation (P = 0.045). Conclusion. Fully guided implant surgery was more accurate than pilot-drill guided surgery for different parameters. For both types of surgery, a safety margin of at least 2mm should be preserved during implant planning to prevent damage to nearby anatomical structures.

Abstract:
Abstract Computer-assisted surgery is based on computerized tomography (CT) scan technology to plan the placement of dental implants and a computer-aided design/computer-aided manufacturing (CAD-CAM) technology to create a custom surgical template. It provides guidance for insertion implants after analysis of existing alveolar bone and planning of implant position, which can be immediately loaded, therefore achieving esthetic and functional results in a surgical stage. The absence of guidelines to treat dentulous areas is often due to a lack of computer-assisted surgery. The authors have attempted to use this surgical methodology to replace residual teeth with an immediate implantoprosthetic restoration. The aim of this case report is to show the possibility of treating a dentulous patient by applying a computer-assisted surgical protocol associated with the use of a double surgical template: one before extraction and a second one after extraction of selected teeth.

Abstract:
Computer-assisted implant planning and subsequent production of a surgical template based on this plan has gained attention because it provides restoratively driven esthetics, patient comfort, satisfaction, and the option of flapless surgery and immediate restoration. However, it adds expense and requires more time. Another significant but not so apparent advantage may be improved survival and success over freehand techniques in types III and IV bone. This retrospective analysis was undertaken to examine that possibility. It reports 1-year outcome for 80 implants in 27 consecutively presenting patients treated over a 7-year period using computer-assisted techniques across all bone qualities in commonly encountered treatment indications in private practice. Implants were placed to support single teeth, small bridges, and complete arch restorations in exposed or immediately restored applications, based on primary stability as determined by insertion torque, resonance frequency analysis, and Periotest. For the 80 implants supporting 35 restorations, the median observation period is 2.66 years; 73 implants supporting prostheses in 22 patients had readable radiographs at 1 year. There was a 1-year overall implant survival and a success rate of 100%. Radiographic analysis demonstrated the change in bone level from the platform at 1-year is less than 2 mm. Intra-operative median measurements of primary stability were insertion torque, 40 Ncm; resonance frequency, 76 ISQ; and Periotest, −3. All intra-operative measurements were consistent for acceptable primary stability regardless of bone density. Restoratively driven diagnosis and precision planning and initial fit were possible with computer-assisted techniques resulting in the achievement of high primary stability, even in areas of less dense bone. The ability to plan implant position, drill sequence, and implant design on the basis of predetermined bone density gives the practitioner enhanced pretreatment information which can lead to improved outcome.

Abstract:
Dental implants are widely recognized as a dependable and cost-effective solution for replacing missing teeth. Achieving successful outcomes in modern implantology and prosthetics depends on rigorous diagnostic methods and diligent planning that meet the expectations of patients and dentists and leverage advancements in materials and digital technologies. The predictability and success rates of implant dentistry have significantly improved following the development of computed tomography, implant planning software, guided implant surgery techniques, and advanced materials. This report presents the case of a 54 year-old healthy male with partial tooth loss who received seven implants in the upper jaw and six in the lower jaw. Based on comprehensive Cone Beam Computed Tomography imaging, the treatment plan was devised to support a fixed prosthesis. Precise implant placement, guided by the treatment plan, addressed the optimal prosthodontic requirements while minimizing invasiveness through a flapless surgery approach. The landscape of rehabilitation practices is evolving due to the incorporation of computer-aided design in treatment planning and the increased application of computer-assisted manufacturing. Guided implant techniques have emerged as a means to mitigate the limitations associated with traditional methods. Compared to conventional approaches, guided implant surgery significantly improves implant placement precision by reducing chairside time, involves minimally invasive procedures, and augments predictability.

Background. The probability of cranial lesions in fibrous dysplasia reaches 50%. A pre-operative computer-assisted planning provides opportunities for precise radical bone resection and customized xenograft manufacturing. Objective. To evaluate postoperative outcomes in patients with fibrous dysplasia of the cranial vault and base, achived by means of preoperative computer-assisted planning and modeling. Material and methods. There were 32 patients with fibrous dysplasia of skull cranioorbital and vault localisation in Moscow National Medical Research Center for Neurosurgery named after Academician N.N. Burdenko from 2008 to 2024. All patients underwent a virtual lesion resection, a surgical template and a customized implant or its mold modelling. Implants were mostly manufactured from polymethylmethacrylate either before or during the surgery. The peculiarities of surgeries were application of template to dysplastic bone, resection within appropriate contour and subsequent cranioplasty with customized cranial implant. After surgery, we performed CT and analyzed deviations between postoperative and virtual skull. Reconstruction quality was assessed evaluating cranial asymmetry by means of craniometric analysis. Results. Craniometric measurements of asymmetry proved the effectiveness of surgical skull correction. The part comparison analysis of skull models after a computer-assisted planning and operations revealed convenience and predictability of the chosen approach. Conclusion. The developed complex of preoperative computer-assisted planning and modeling significantly improved resection and cranioplasty quality.

Abstract:
Traditional dental implant surgery has been challenged by the phenomenal progression in computer-assisted surgery (CAS) that we have been witnessing in recent years. Among the computer-aided technologies, computer-aided design and computer-aided manufacturing (CAD/CAM) techniques represent by far the most attractive and accepted alternatives over their dynamic counterpart, navigational assistance. Based on many years of experience, we have determined that CAD/CAM technology for guiding dental implant surgery is valuable for rehabilitation of the anterior maxillary region and the management of complete or severe partial edentulism. The technology also guarantees the 3D parallelism of implants. The purpose of the present report is to describe indications for use of CAD/CAM dental implant guided surgery. We analyzed the clinical and radiological data of thirteen consecutive edentulous patients treated using CAD/CAM techniques. All of the patients had stable cosmetic results with a high rate of patient satisfaction at the final follow-up examination. No intra- and/or postoperative complications were encountered during any of the steps of the procedure. The application of CAD/CAM techniques produced successful outcomes in the patients presented in this series.

The aim of this study is to assess the accuracy of immediately placed implants using Anatomage Invivo5 computer-assisted design/computer-assisted manufacturing (CAD/CAM) surgical guides and compare the accuracy to delayed implant placement protocol. Patients who had implants placed using Anatomage Invivo5 CAD/CAM surgical guides during the period of 2012–2015 were evaluated retrospectively. Patients who received immediate implant placements and/or delayed implant placements replacing 1–2 teeth were included in this study. Pre- and postsurgical images were superimposed to evaluate deviations at the crest, apex, and angle. A total of 40 implants placed in 29 patients were included in this study. The overall mean deviations measured at the crest, apex, and angle were 0.86 mm, 1.25 mm, and 3.79°, respectively. The means for the immediate group deviations were: crest = 0.85 mm, apex = 1.10, and angle = 3.49°. The means for the delayed group deviations were: crest = 0.88 mm, apex = 1.59, and angle = 4.29°. No statistically significant difference was found at the crest and angle; however, there was a statistically significant difference between the immediate and delayed group at the apex, with the immediate group presenting more accurate placements at the apical point than the delayed group. CAD/CAM surgical guides can be reliable tools to accurately place implants immediately and/or in a delayed fashion. No statistically significant differences were found between the delayed and the immediate group at the crest and angle, however apical position was more accurate in the immediate group.

Abstract:
Successful implant placement in augmented sites depends on the appropriate bone volume and quality, as well as careful planning of the procedure. Minimizing risks during the surgical and healing phases is also of great importance. A very promising technique has been introduced, which partially meets the above criteria. This technique is designed to increase the precision and reduce the invasiveness associated with surgical procedures during implantation. The aim of this clinical study was to analyze the accuracy of computer-guided implant surgery in augmented sites in patients treated with dental implants introduced using dynamic implant navigation. Eleven healthy patients who had planned and performed implant-prosthetic treatment after bone augmentation were analyzed. Twenty-three implants were placed with Navident dynamic navigation using the tissue punch flapless technique. This study evaluated the position of the inserted implant relative to the virtual plan and determined the correlation. The treatments were successful in all the treated patients, and the integration period (3 or 6 months) was uneventful and enabled implant-prosthetic treatment. The accuracy values provided in this study are comparable to, but not better than, data provided in the literature on dynamic and static computer-assisted surgery. Dynamic navigation may improve the quality and safety of surgical procedures and reduce the risk of complications.

Abstract:
Introduction: Techniques and workflows have been developed to use guided surgery in most clinical patient case applications, such as immediate implant placement; tilted implant/hybrid restoration and implant placement. Aims: Integrating the guide sleeves is a manual process, as is the removal of holding or support structures. Methods/Materials: Different techniques have been developed to transfer the ideal implant position to the surgical field, using templates. Implant planning software matches CT data to wax up information, allowing the clinician to view a 3D image of the jaw when planning implant position. Results: Guided implant surgery makes it easy for the clinician in rendering optimal clinical outcome. Computer-assisted implantology has found to overcome the errors encountered during implant site preparation more precisely. Conclusion: The protocols that need to be followed by this technique are based upon the concept of prosthetic-driven implantology and CT-scan analysis.

Abstract:
OBJECTIVES To compare 2D CT alone with 2D + 3D reconstruction for pre-operative planning of implant placement. METHODS Spiral CT scans of 33 consecutive patients were used for both reformatted 2D and 3D computer-assisted planning. The number, site and size of implants and the occurrence of anatomical complications during planning and implant placement were statistically compared using the percentage agreement and the Kendall's correlation coefficients (tau). Although planning was performed in 33 patients, implants were only placed in 21 patients. In 11 patients surgery was based on 2D + 3D imaging and in ten patients on 2D planning. RESULTS Agreement between planning and placement of implants was highly significant for the implant sites selected. For 2D based planning and placement, agreement reached 68% (tau = 0.94). For 2D + 3D based planning and placement, agreement attained 73% (tau = 0.89). For planning and placement of implant size based on 2D images, agreement was 31% and not significant (tau = 0.23). When based on 2D + 3D images, agreement for implant size was 44% (tau = 0.5). Agreement was not significant for anatomical complications: 69% for 2D planning and 71% for 2D + 3D planning (tau = 0.24 for 2D and tau = 0.21 for 2D + 3D). CONCLUSIONS The 3D planning system is a reliable tool for pre-operative assessment of implant placement. Both 2D and 2D + 3D planning have a good predictability for the number and site of the implants but less so for anatomical complications. However, the 2D + 3D planning provides a better pre-operative assessment of implant size.

Abstract:
Computer-assisted surgery (CAS) has revolutionised surgical procedures in both medicine and dentistry. This review explores the benefits and limitations of CAS in maxillofacial surgery. Virtual surgical planning allows for a clear declaration of surgical intentions, avoiding conflicts between resection and reconstruction teams, and enabling communication of preferences and uncertainties. CAD-CAM software facilitates virtual surgery and generates templates and cutting guides for precise implementation in the operating room. CAS has had a significant impact on dental implant placement, enabling accurate positioning and improved outcomes. It also aids in skull base surgery and the removal of foreign bodies. Navigation systems provide real-time tracking and visualisation, ensuring accuracy and safety. However, because of the mandible's movement, there are restrictions, especially in mandibular surgery. Despite these challenges, CAS offers numerous advantages, including increased precision, reduced anaesthesia time, and improved efficiency

Abstract:
Background and Objectives: The present systematic review and meta-analysis undertake a comparison of studies that examine the accuracy of robot-assisted dental implant placement in relation to static computer-assisted implant surgery (SCAIS), dynamic computer-assisted implant surgery (DCAIS), and freehand procedures. This study aims to provide a comprehensive understanding of the precision of robot-assisted dental implant placement and its comparative efficacy in relation to other placement techniques. Methods: The guidelines recommended by Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) were used to organize and compose this review. Four electronic databases (PubMed, Web of Science, Scopus, and Cochrane) were systematically searched for pertinent articles. Articles were selected following the inclusion and exclusion criteria. Qualitative and quantitative analyses of the selected articles were performed. Results: The initial electronic search resulted in 1087 hits. Based on the inclusion and exclusion criteria, five articles were selected for qualitative analysis, out of which three were considered for quantitative analysis. Three parameters were considered for accuracy evaluation (angular, coronal, and apical deviation). The mean angular deviation was −1.22 degrees (95% CI, −1.06–−1.39), the mean coronal deviation was −0.15 mm (95% CI, −0.24–−0.07), and the mean apical deviation was −0.19 mm (95% CI, −0.27–−0.10). Conclusions: The robotic implant system was found to have significantly lower angular deviations and insignificantly lower coronal and apical deviations compared to DCAIS. Within the limitations of this review, it can be concluded that robot-assisted implant placement in resin models permits higher accuracy compared to DCAIS and SCAIS systems. However, due to the limited number of comparative studies with high heterogeneity, the findings of this review should be interpreted with caution. Further research is necessary to confirm the clinical application of robotics in implant surgery.

Abstract:
Virtual and augmented reality are both integrated into mixed reality, enabling users to interact with real or artificial environments based on their needs. Integrating mixed reality into dental loupes could reduce treatment time and minimize the need to constantly look away from patients to consult computer screens. This study aims to determine the impact of mixed reality adoption by examining digital screen usage in X-Guide navigated implant surgeries, and to evaluate whether newly adopted assisted reality for navigated implant surgeries reduces computer screen dependency. This retrospective analysis involves two oral surgeons with a total of 55 treated patients. Data from these practitioners will assess mixed reality implementation in dental loupes, measuring their interactions with digital computers based on the treatment type. All implant surgeries utilized X-Guide by X-Nav Technologies. Statistical analysis was conducted using two-sample t-tests to identify whether the usage of assisted reality glasses in implant surgeries reduces treatment time and computer usage. An ANOVA test revealed significant variance in computer usage, indicating that mixed reality benefits vary across oral surgical procedures. Two independent two-sample t-tests revealed a statistically significant 22.1% reduction in treatment time and an 66.7% reduction in computer usage in X-Guide implant surgeries utilizing assisted reality. The findings on computer usage indicated that oral surgery could benefit significantly from mixed reality adoption. Digital implant surgeries with mixed reality integrated loupes would be more advantageous for implant procedures by enabling hand interaction, a feature not available in the screen-mirroring assisted reality glasses used in this study.

Abstract:
This study compared the accuracy of static computer-assisted implant surgery (sCAIS) planned through dental surface image registration and fiducial marker registration. Stone models of 30 patients were converted into digital dental casts by using a desktop scanner. Cone-beam computed tomography (CBCT) was performed and superimposed to the digital dental casts with two methods: matching the dental surface images or matching the fiducial markers on a stereolithographic radiographic template. Following the implant planning, stereolithographic surgical guides were fabricated, and 56 fully guided implants were inserted by the same doctor. Deviations between planned and inserted implants were measured and compared using postoperative CBCT images. After adjustment for other potential influencing factors, compared with the fiducial marker registration group, significantly larger mean lateral deviations were noted in the dental surface registration group at both the implant platform and apex (p = 0.0188 and 0.0371, respectively). However, the mean lateral deviations for the dental surface registration (0.83 ± 0.51 mm at implant platform and 1.24 ± 0.68 mm at implant apex) were comparable to the literature. In conclusion, our findings indicate that although sCAIS planned using dental surface image registration was not statistically as accurate as that using fiducial marker registration, its accuracy was satisfactory for clinical use.

Full text
Abstract:
Shoulder arthroplasty, including total shoulder arthroplasty (TSA) and reverse shoulder arthroplasty (RSA), is a well-established procedure for treating degenerative, post-traumatic, and inflammatory conditions of the shoulder joint. The success of these surgeries depends largely on the precise placement of implants, which helps restore proper joint mechanics, reduce complications, and extend the lifespan of the prosthesis. However, achieving accurate implant positioning can be challenging, especially in cases involving severe bone loss, anatomical deformities, or prior surgeries. Poor alignment can lead to instability, implant loosening, and the need for revision surgery. Computer-assisted navigation has become an important tool in shoulder arthroplasty, providing real-time intraoperative guidance to improve surgical accuracy and consistency. By integrating preoperative 3D imaging with intraoperative tracking, navigation technology allows surgeons to optimize glenoid component placement, reducing the risk of malalignment and mechanical failure. Research suggests that navigation-assisted techniques improve precision, enhance functional outcomes, and may even reduce complication rates by optimizing fixation strategies, such as using fewer but longer screws in RSA. Despite its benefits, navigation in shoulder arthroplasty is not without challenges. It requires additional surgical time, increases costs, and demands a learning curve for surgeons. However, with advancements in artificial intelligence, augmented reality, and robotic-assisted surgery, navigation is expected to become even more effective and accessible. This review explores the current impact of navigation on clinical outcomes, its role in complex cases, and the future potential of this technology. While early results are promising, further long-term studies are needed to fully assess its value and establish best practices for its routine use in shoulder arthroplasty.

Abstract:
The aim of the current study was to evaluate the learning curve and accuracy of implant placement by young professionals using a dynamic computer-assisted surgical system for dental implant placement. Ten students tried to place eight implants with a dynamic surgical system in predefined positions on two consecutive weekends, resulting in 160 implant placements in total. Postoperatively, the positions of the implants were scanned with an intraoral scanner and compared for deviations at the entry point, the apex, as well as angular deviations to the master model. The mean values of all measurements improved; statistical significance was found for the changes in the angle as well as for the position of the implants to the apex (p &lt; 0.001). Furthermore, the young professionals indicated subjective improvement in handling the dynamic surgery system. Navigated surgical dental implant placement can be learned quickly and can support young professionals in everyday clinical practice, especially in difficult anatomic situations.

Abstract:
Abstract BACKGROUND The development of computer-assisted design, virtual modeling, and computed tomography has allowed precise customization of implants for patients who undergo neurosurgical or craniofacial surgery procedures. However, such techniques and implant designs have not adequately addressed temporal asymmetry due to postoperative bone resorption, temporalis muscle malposition/foreshortening, and/or temporal fat pad atrophy. OBJECTIVE We hypothesized that an alteration in customized craniofacial implant (CCI) design with a strategic extension inferolaterally and excessive material bulking would provide simultaneous reconstruction of coexisting temporal skull defects and therefore reduce the effect of soft tissue deformities. METHODS A single-surgeon, single-institution retrospective cohort study was performed to include 10 consecutive subjects who underwent cranioplasty reconstruction with modified implants during a 3-year period. Implants were placed with the use of our previously described pericranial-onlay technique. With the use of a computed tomography-based, computer-assisted design/manufacturing methodology, novel dual-purpose implants were designed to prevent and/or correct persistent temporal hollowing. The efficacy of the new CCI shape and design for cranial restoration of temporal symmetry was analyzed in both 2 and 3 dimensions. RESULTS In 2-dimensional analyses, the modified implant provided enhanced lateral projection (21%; 1.06 cm) in areas closest to the temporal arch. Three-dimensional volumetric analyses demonstrated that additional bulking totaled 24 ± 11 cm3 (range, 9-43 cm3), which essentially replaced 40 ± 13.7% (range, 26%-60%) of the absent temporal volume contributing to persistent temporal hollowing. CONCLUSION Computer-designed, dual-purpose CCIs can be safely created with unprecedented shape to prevent and/or eradicate postoperative temporal deformity.

Abstract:
Background: Recently, intraoral scanning (IOS) has been proposed as a new tool to evaluate the accuracy of static computer-assisted implant surgery (s-CAIS); however, further research is needed to improve the precision of IOS for full-arch impressions. The purpose of the study was to assess the accuracy of s-CAIS in an edentulous patient either in vivo or in vitro with two different evaluation techniques and to investigate if their results are comparable. Methods: A patient with terminal dentition was selected and four implants were placed using s-CAIS with a bone-supported stackable template. Segmentation used for designing a template was 3D printed, and then four implants were placed in the model following the same protocol as for s-CAIS. The model then underwent cone beam computed tomography (CBCT) and laboratory scanning to evaluate its accuracy. Data were uploaded to specific software, and accuracy values were automatically generated. Results: A statistical analysis was not attempted since all measurements were performed on the same patient and model. When descriptively comparing the accuracy of the two methods of treatment evaluation in the in vitro scenario, comparable results were obtained between IOS and CBCT, except for the angle. Conclusions: As the intraoral scanning procedure in fully edentulous patients is not yet clinically validated, utilizing CBCT can still be recommended for the accurate evaluation of computer-assisted implant placement.

The exact location of the maxillary sinuses, and other relevant vital structures such as mandibular canal, mental and incisal foramen canal. Once the images are imported, to the software the clinician can then virtually begin treatment planning. The type and size of the planned implant, its position in the bone, its relationship to the restoration and adjacent teeth and/or implants, and its proximity to vital structures can be determined prior to surgery. Computer-generated surgical drill guides can then be manufactured from the virtual treatment plan.

Purpose. To compare knee alignments in total knee arthroplasty (TKA) using computer-assisted navigation versus conventional guiding systems. Methods. Five men and 49 women aged 49 to 79 years underwent TKA for primary osteoarthritis of the knee with varus deformity. All valgus knees were associated with inflammatory arthritis and thus excluded. Computer-assisted navigation was used for the first 35 TKAs, whereas conventional extramedullary tibial and intramedullary femoral guiding systems were used for the next 35 TKAs. The mechanical axis, coronal tibial and femoral angles, sagittal tibial and femoral angles in the 2 groups were compared. Results. Sagittal tibial and femoral angles aligned more optimally in TKAs using computer-assisted navigation. In the respective computer-assisted navigation and conventional guiding systems, 33 (94%) and 26 (74%) of the TKAs attained a postoperative mechanical axis of &lt;3° varus/valgus. Conclusion. Computer-assisted navigation gives a more consistent alignment correction and reduces outliers during implant positioning.

Abstract:
Abstract Surgical guides have evolved to the point that they can be created with the aid of computer-assisted tomography (CT) technology. Surgical guides also are used in construction of the prosthesis prior to implant surgery. With existing guide techniques, the prosthesis is screw retained, or cone-shaped temporary abutments may be used to overcome the lack of parallelism of the implants. With the New Twist technique, we are able to create the surgical guide in such a way that optimum bone may be used and the rotational position of the implant may be established for the surgeon and for the laboratory. Custom abutments are inserted at the time of surgery, as is an esthetic, functionally provisional cemented prosthesis. Castings for the finished ceramo-metal bridge are fabricated before surgery is performed. The final prosthesis then is easily constructed by the restorative dentist during just 3 simple patient visits.

The aim of our randomized clinical study was to analyze the influence of surgical experience and bone density on the accuracy of static computer-assisted implant surgery (CAIS) in edentulous jaws using a mucosa-supported surgical template with a half-guided implant placement protocol. Altogether, 40 dental implants were placed in the edentulous jaws of 13 patients (novice surgeons: 18 implants, 6 patients (4 male), age 71 ± 10.1 years; experienced surgeons: 22 implants, 7 patients (4 male), age 69.2 ± 4.55 years). Angular deviation, coronal and apical global deviation and grey level measurements were calculated for all implants by a blinded investigator using coDiagnostiX software. 3DSlicer software was applied to calculate the bone volume fraction (BV/TV) for each site of implant placement. There were no statistically significant differences between the two study groups in either of the primary outcome variables. There was a statistically significant negative correlation between angular deviation and both grey level measurements (R-value: −0.331, p &lt; 0.05) and BV/TV (R-value: −0.377, p &lt; 0.05). The results of the study suggest that surgical experience did not influence the accuracy of implant placement. The higher the bone density at the sites of implant placement, the higher the accuracy of static CAIS.

Abstract:
Introduction: In recent years, computer-assisted surgery has made it possible to undergo surgery with a high degree of precision. This study aimed to investigate the usefulness of computer-assisted surgery for femoral trochanteric fractures using the ADAPT (ADAptive Positioning Technology) system. Methods: A total of forty patients with femoral trochanteric fracture underwent intramedullary nailing for fracture fixation: in twenty patients, the ADAPT system (ADAPT group), and in the other twenty, it was not used (control group). The operative time, intraoperative fluoroscopy time, tip apex distance (TAD), and tip to head surface distance (TSD) were measured and compared between the two groups to assess the efficiency and accuracy of the surgery. Results: The operative time was significantly shorter (P &lt; 0.05), intraoperative fluoroscopy time was significantly reduced (P &lt; 0.01), and implant placement was significantly better in the ADAPT group (P &lt; 0.01). Conclusion: Navigation systems have been developed to improve the efficiency of surgery. The ADAPT system was considered a very useful device for intramedullary nailing of femoral trochanteric fractures, as it reduced the intraoperative fluoroscopy time and improved the accuracy of implant placement, also reducing the operative time.

Abstract:
Purpose: When compared to conventional freehand procedures, the development of computer-assisted techniques in dental implant insertion surgery has significantly changed traditional practices, bringing about a movement toward improved precision and predictability. The purpose of this study was to evaluate the efficiency of traditional freehand methods versus static–dynamic computer-assisted dental implant placement procedures in terms of accuracy and precision. Methodology: This study followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, screening 438 articles from databases such as PubMed, Embase, Scopus, and Web of Science. The inclusion criteria were randomized and nonrandomized control trials, case controls and retrospective case studies, focusing on platform deviation, angular deviation, and apical deviation in dynamic, static, and freehand surgeries. Eleven studies were selected for a review, with nine studies included in the meta-analysis. Heterogeneity was analyzed using appropriate statistical models to ensure robust findings and reliability of the results. Results: The meta-analysis included nine studies comparing dental implant accuracy across dynamic, static, and freehand placement techniques. Dynamic systems showed superior accuracy, with platform deviations of 0.64–1.73 mm, angular deviations of 2.49°–5.75°, and apical deviations of 0.89–1.86 mm. Static systems showed slightly greater variability, with platform deviations of 0.97–2.34 mm and angular deviations of 2.2°–4.98°. Freehand techniques demonstrated the highest deviations, with platform deviations up to 3.48 mm and angular deviations up to 10.09°. Prediction intervals indicated consistent superiority of dynamic guidance across metrics. Conclusion: When compared to static and freehand methods, dynamic computer-assisted dental implant surgery provides more accuracy and precision. In implant dentistry, adopting dynamic guided systems is essential to attaining the best clinical results and raising patient satisfaction.

Abstract:
Orthopaedic procedures have changed dramatically in the last several years due to the spectacular developments in joint replacement surgery. The purpose of this review article is to clarify the various developments in joint replacement surgery with an emphasis on improving patient satisfaction and long-term results. The study looks at five important topics: patient selection, prosthetic materials, surgical techniques, technological advancements, and long-term outcomes.&#x0D; Precision and implant longevity have been transformed by technological advancements such as 3D printing, robotic-assisted surgery, and computer-assisted navigation. Modern surgical methods have a strong emphasis on tissue preservation, less invasive procedures, and improved recovery protocols, which greatly lower postoperative problems and speed up recovery. Prosthetic material advancements including highly cross-linked polyethylene and customised designs have enhanced patient-specific results and implant longevity. In order to maximise surgical success and satisfaction, patient selection criteria, customised care regimens, and psychological support have become essential. When long-term results are assessed, functional abilities, implant durability, and patient satisfaction all show notable improvements; nonetheless, problems with complications and revision operations still exist.

Abstract:
As a person ages, usually after age 50, knee joint bone damage caused by osteoarthritis can occur. It is to cause pain in the knee joint so that its function moves abnormally. The knee joint bone damage could be replaced with a prosthesis (Total Knee Replacement, TKR) to restore the knee joint's normal movement function. However, orthopaedic doctors sometimes have difficulty choosing standard implant designs available for patients' knees when performing TKR surgery, especially for Asian patients, including Indonesians. It is due to the geometry of the standard implant being different from the patient's knee anatomical shape. As a result, postoperative pain reactions can occur. Therefore, this study is to customize the TKR femoral implant's design according to the knee bone's geometry, especially in Indonesian patients. Reverse Engineering (RE) technology assisted by the CT-Scan and the boundary surface technique was applied for reconstructing the patient's knee bone into a femoral implant. The application of RE is initially, the patient's knee bone sample was scanned with Computer Tomography (CT) Scan. Then, the femur implant model was designed on the surface of the patient's knee bone using the boundary surface method. The 3D model of the TKR femoral implant was successfully designed to match the geometry of the patient's femur bone. It will be a reference for designing other TKR implants, namely the tibia component.

Abstract:
Abstract Introduction Reports on the use of computer-assisted trauma surgery of comminuted scapula fracture are still quite rare. In this article, we present a case of comminuted scapula fracture, the surgical reconstruction of which was pre-operatively planned using a complex software solution. Materials and methods For surgical planning of the fracture, we used the TraumaTech software facilitating virtual reconstruction (both manual and automatic), surgery planning, design of the implant, planning of screw placement and lengths, and production of a 3D print model of the fracture and the implant. The software also supported ordering such custom-made plate from a plate producer who was capable of fast and precise production of the plate. Results The surgery using the custom-ordered plate was successful. The actual used screw lengths did not differ from the planned ones by more than 2 mm. One year after the surgery, the patient was capable of more demanding activities and doing sports activities. Conclusion This approach provides a great way to prevent complications of the surgery and to shorten its duration. To the best of our knowledge, this is the first description of the treatment of a scapula comminuted fracture utilizing computer-assisted preoperative planning.

Abstract:
One of the techniques available for prosthetic rehabilitation of lost teeth are implants. Earlier implants were placed in a surgically driven treatment approach. Later the idea of placing implants on the basis of prosthetically driven treatment approach was derived by introduction of computer assisted surgery. Dynamic navigation is a technique of computer assisted surgery where the operator can perform accurate, easy and flapless implant insertion surgeries even within a single day. These navigation systems are continuously evolving to achieve even better ways of implant placement. This review will briefly highlight on the details of this navigation implant surgery.
