Computer-aided implantology has developed rapidly in recent years, this study aimed to compare the accuracy of guided-surgery between anterior immediate and delayed implantation, and simultaneously assess the effect of full-guided and half-guided templates on accuracy values. Seventy-six implants were inserted in 63 patients using full-guided or half-guided template in the anterior zone. Postoperative cone beam computed tomography (CBCT) was matched with preoperative planning to evaluate the deviation between actual and planned implants. No statistical difference was found in any deviation between immediate and delayed implantation (p > 0.05). In anterior immediate implantation, the global coronal, apical, depth and angular deviations of full-guided templates were all significantly lower than those of half-guided templates (0.66 ± 0.26 vs. 1.10 ± 0.76 mm, 0.96 ± 0.41 vs. 1.43 ± 0.70 mm, 0.46 ± 0.24 mm vs. 0.93 ± 0.79 mm and 1.69° ± 0.94° vs. 2.57° ± 1.57°). While in delayed implantation, full-guided templates only perform better with statistical significance on global apical and depth deviation (1.01 ± 0.42 vs. 1.51 ± 0.55 mm and 0.32 ± 0.26 vs. 0.71 ± 0.47 mm). After excluding the influence of depth deviation, the coronal and apical deviations between the two systems in immediate implantation and the apical deviations in delayed implantation had no statistical difference. Within the limit of this study, the results suggested the accuracy of guided-surgeries for anterior immediate and delayed implantations was comparable, and full-guided template was more accurate for immediate and delayed implantation.

<p>The palatal coverage is considered as an auxiliary element in the distribution of tensile strains on implant maxillary total prosthesis (implant overdentures) bases, either implant-supported or retained. However, complaints in some patients due to palate and phonetic impairment are constant. The palatal coverage removal would allow the improvement of these issues as well as pharyngeal control, salivary flow and hygiene. Thus, this literature review proposed to analyze the survival rates of dental implants retaining an implant maxillary overdenture without palatal coverage in edentulous maxilla. The review was conducted in Medline database, via PubMed between 2000 to 2016 period, and limited to English language publications. The search strategy took the following key-words, referencing title and / or abstract: dental implants; maxilla; maxillary; overdenture; and palatal coverage. According the data, the rehabilitation of the maxillary edentulous with four implant-supported overdentures with bar attachments and implant-retained with ball attachments has shown great survival rates of dental implants, but there are a few studies reporting the survival rate of implant overdentures.  It was concluded that the prosthetic rehabilitation of total maxillary edentulous patients is viable through palateless implant overdentures when a minimum of four to six implants were used with careful planning and execution.</p><p> </p><p><strong>Keywords</strong></p><p>Dental Implants; Maxilla; Overdenture and Palatal coverage.</p>

Introduction: In the context of implant dentistry, dental implants represent about 1,000,000 procedures per year worldwide. Virtual implant planning systems integrate cone beam computed tomography (CT) data to assess the amount of bone and virtual models for the project of a dental implant. Objective: It presented, through a systematic review, the main considerations of guided surgery in implant dentistry through evidence from clinical studies and important systematic reviews on the subject. Methods: The research was carried out from May 2021 to June 2021 and developed based on Scopus, PubMed, Science Direct, Scielo, and Google Scholar, following the Systematic Review-PRISMA rules. The quality of the studies was based on the GRADE instrument and the risk of bias was analyzed according to the Cochrane instrument. Results: A total of 112 articles were found on guided surgery and implantology. Initially, duplication of articles was excluded. In total, 54 articles were fully evaluated and 23 were included and evaluated in this study. In the GS scenario, advances in technology have contributed to the improvement of models with favorable positioning of implants in aesthetic terms. This provides the predictability of techniques and difficulties that may be encountered during surgical intervention, reducing time and the possibility of errors, allowing for an overall reduction in the costs of oral rehabilitation. Conclusion: Guided surgery is considered accurate and reliable compared to free implant surgery. However, the learning curve is undeniable and a clinician with basic surgical skills, including conventional implant dentistry.

Abstract Background The aim of this study was to assess the accuracy of virtual planning of computer-guided surgery based on the actual outcomes of clinical dental implant placement. Methods This retrospective study enrolled patients among whom implant treatment was planned using computer-guided surgery with cone beam computed tomography (CBCT). The patients who received implant according to the guide with the flapless and flapped approach were classified as group 1 and 2, respectively, and the others who could not be placed according to the guide were allocated to the drop-out group. The accuracy of implant placement was evaluated with the superimposition of CBCT. Results We analyzed differences in the deviated distance of the entrance point and deviated angulation of the insertion of implant fixtures. With regard to the surgical approach, group 2 exhibited greater accuracy compared to group 1 in deviation distance (2.22 ± 0.88 and 3.18 ± 0.89 mm, respectively, P < 0.001) and angulation (4.27 ± 2.30 and 6.82 ± 2.71°, respectively, P = 0.001). The limitations of guided surgery were discussed while considering the findings from the drop-out group. Conclusions Computer-guided surgery demonstrates greater accuracy in implant placement with the flapless approach. Further research should be conducted to enhance the availability of guides for cases with unfavorable residual bone conditions.

Introduction: Dental implant procedures have increased worldwide, reaching approximately one million dental implants per year. The optimization of faster and more accurate techniques by dentists and postoperative surgeons with better results and quality of life stimulated the development of numerous software and hardware for performing computer-guided surgeries, so-called virtual surgeries (VS). Objective: to present, through a systematic review, the main considerations of virtual surgery in dentistry and their respective advantages, disadvantages, and limitations. Methods: The model used for the review was PRISMA. We used databases such as Scielo, Lilacs, Google Scholar, PubMed. Major findings: In the scenario of VS in dentistry, advances in technology have contributed to the improvement of the models, since there was only the direct molding technique to obtain patient models, with the positioning of implants not very favorable in terms aesthetics. The information that is acquired in the 3D reconstructions allows us to determine the quantity and quality of the available bone and also allows the simulation of the installation of the implants in a virtual environment. This provides predictability of techniques and difficulties that can be encountered during surgical intervention, reducing the time and the possibility of errors, allowing the overall reduction of oral rehabilitation costs. Conclusion: Preoperative virtual planning and reconstruction of the mandible guided by dental implants through preoperative designs provide high success rates for the implant and dental rehabilitation, benefiting also prosthetic restorations supported by fixed implants. Still, the concept of using personalized implants with the help of 3D virtual treatment planning, stereolithographic models, and computer-assisted design greatly improves the mandibular restoration and helps to obtain a good facial profile, aesthetic and dental rehabilitation, avoiding complications with the grafts autologous.

Abstract Purpose Dental implant surgery was developed to be the most suitable and comfortable instrument for dental and oral rehabilitation in the past decades, but with increasing numbers of inserted implants, complications are becoming more common. Diabetes mellitus as well as prediabetic conditions represent a common and increasing health problem (International Diabetes Federation in IDF Diabetes Atlas, International Diabetes Federation, Brussels, 2019) with extensive harmful effects on the entire organism [(Abiko and Selimovic in Bosnian J Basic Med Sci 10:186–191, 2010), (Khader et al., in J Diabetes Complicat 20:59–68, 2006, 10.1016/j.jdiacomp.2005.05.006)]. Hence, this study aimed to give an update on current literature on effects of prediabetes and diabetes mellitus on dental implant success. Methods A systematic literature research based on the PRISMA statement was conducted to answer the PICO question “Do diabetic patients with dental implants have a higher complication rate in comparison to healthy controls?”. We included 40 clinical studies and 16 publications of aggregated literature in this systematic review. Results We conclude that patients with poorly controlled diabetes mellitus suffer more often from peri-implantitis, especially in the post-implantation time. Moreover, these patients show higher implant loss rates than healthy individuals in long term. Whereas, under controlled conditions success rates are similar. Perioperative anti-infective therapy, such as the supportive administration of antibiotics and chlorhexidine, is the standard nowadays as it seems to improve implant success. Only few studies regarding dental implants in patients with prediabetic conditions are available, indicating a possible negative effect on developing peri-implant diseases but no influence on implant survival. Conclusion Dental implant procedures represent a safe way of oral rehabilitation in patients with prediabetes or diabetes mellitus, as long as appropriate precautions can be adhered to. Accordingly, under controlled conditions there is still no contraindication for dental implant surgery in patients with diabetes mellitus or prediabetic conditions.

Abstract Objectives The aim of this research was to develop a sensor of approximation by reflectance for guided surgery with dental implants without flap detachment, and verify the effectiveness of this system. Materials and Methods Ten models of total edentulous arches were divided into two groups. Two implants of 3.5 × 11.5 mm (NeoDent) were inserted in each model; in Group 1 (G1), a stereolithographic guide NeoGuide system was used. In Group 2 (G2), the experimental approximation sensor was used for the insertion of the implants. The evaluation of the results was performed by overlapping the virtual planning images with the tomographies of the models of the implants inserted. Results There were no statistically significant differences between the guide and the sensor groups. The averages and standard deviations observed at the angulation of the guide was 4.15 (2.65 degrees) and 5.48 (2.85 degrees) at the sensor. The linear deviations at the cervical level were 0.002 (1.37) and 0.11 (1.47) mm and at the apical level 0.19 (1.28) and 0.21 (1.42) mm, respectively. Conclusions The use of a guide is important for the stabilization of the drills; the greatest challenge is to control the apical position of the implants, especially in highly reabsorbed edges. The experimental sensor can become an auxiliary tool to the stereolithographic guides; however, several difficulties must still be overcome to recommend the use of a sensor.

The loss of teeth is always challenging for the patients. It is not only a functional loss but also a psychological and social loss. But with the advent of dental implants, this clinical situation can be dealt with tactfully. In an edentulous arch, prosthetic rehabilitation by all on 6 implants require accurate placement of implants for a successful result. A computer-guided surgical stent can be advantageous over arbitrary placement of implants and can overcome the difficulties associated with arbitrary placement. Using the cone beam computed tomography of the patient, virtual planning of implant is done. The exact implant angulations can be visualized to achieve the best possible esthetics and occlusion. This information is then converted to fabricate a stent using three-dimensional printing. Using this stent, a flapless surgical implant placement can be done which will reduce the post-operative trauma. This case report describes a case of a patient having an edentulous mandibular arch. The prosthetic rehabilitation of the mandibular arch was done by flapless surgical placement of six implants using a computer-guided surgical stent.
