<p>In the article on the basis of the literature are shown main errors during dental implantation, as well as the difficulties encountered by the dentist orthopedist during the stage of prosthetics on implants<br />in the absence of parallel superstructures, as well as improperly installed cylindrical implants. On the example of the technology of the planning of surgical stage of implant placement using a surgical<br />template and software complex IMPLANT-ASSISTANT® is shown that orthopedist can not only plan the position of the implants, but also to predict the outcome of orthopedic treatment of partial or total loss of teeth with implants. The article shows the algorithms of treatment of patients with surgical guide and software complex IMPLANT-ASSISTANT®, as well as on clinical examples illustrates the results of this technology. It is talked about future work results of the medical team in Yekaterinburg.</p>

Purpose: To compare virtual planning accuracy of novel computer-assisted, template-based implant placement techniques, which make use of CAD/CAM stereolithographic surgical templates with or without metallic sleeves. Furthermore, to compare open versus closed sleeves for templates without metallic sleeves. Materials and methods: Any partially edentulous patients requiring at least one implant to be placed according to a computer-assisted template-based protocol were enrolled. Patients were randomized according to a parallel group design into two arms: Surgical template with or without metallic sleeves. Three deviation parameters (angular, horizontal, vertical) were defined to evaluate the discrepancy between the planned and placed implant positions. Results: No implants failed, and no complications were experienced. Forty-one implants were placed using surgical templates with metallic sleeves while 49 implants were placed with a surgical template without metallic sleeves. Of these, 16 implants were placed through open sleeves and 33 through closed sleeves. There was a statistically significant difference in angle (p = 0.0212) and in the vertical plan (p = 0.0073) with lower values for implants placed with a surgical template without metallic sleeves. In the test group, close sleeves were more accurate compared with open sleeves in angle (p = 0.0268) and in horizontal plan (p = 0.0477). Conclusion: With the limitations of the present study, surgical templates without metallic sleeves were more accurate in the vertical plan and angle compared to the conventional template with metallic sleeves. Open sleeves should be used with caution in the molar region only in case of reduced interarch space. Further research is needed to confirm these preliminary results.

Subject. Since the mid-20th century, there has been an increase of interest in implantation for the treatment of partial and complete loss of teeth. P. I. Branemark was one of the first pioneers who developed an implant that forms osseointegration. Anatomical restrictions and restorative requirements prompt the implantologist to achieve the accuracy of planning and surgical positioning of dental implants. The ideal placement of the implant facilitates the creation of favorable forces on implants and prosthetic structures, and also provides an aesthetic result. Therefore, it is advisable to establish a logical continuity between the planned restoration and the surgical stages, it is important to use the transmitting device, which undoubtedly increases the effectiveness of the implantation. In 1987, M. J. Edge et al. recommended the use of surgical guides before the implantation operation. Currently, surgical templates have become increasingly used. The article presents data on the features of planning of implant placement and the technology of applying a surgical template for positioning the dental implant unit. Goal. To show the value of using surgical templates for the rational installation of dental implants and preventing possible errors and complications. Methodology. A search for literature using search engines such as Google, Yahoo and scientific bibliographic databases such as PubMed, Medline and textbooks was conducted until September 2017 using medical thematic headings like «Dental Implants», «Surgical Templates». More than 300 sources of literature were identified, after studying which they reduced to 28 sources of articles and literary reviews. Conclusions. The study of available to us literature, revealed the advantages and disadvantages of using surgical templates. The main advantages: precise placement of implants, preservation of anatomical structures; three-dimensional technology allows to accurately estimate anatomical points, such as the size of the maxillary sinus in the upper jaw and the location of the alveolar nerve in the lower jaw, high observable accuracy of 0.1 mm, reduction of the time of surgical intervention. Disadvantages: lack of visibility and tactile control during the surgical procedure, insufficient opening of the mouth jeopardizes the result of complex treatment, there is a risk of damage to vital anatomical structures.

Guided implant dentistry using computed tomographic (CT) scans, virtual planning software and mucosa-supported surgical templates is an upcoming technology with the potential for more predictable and less invasive implant placement. While generally associated with a flapless approach, soft tissue punching and removal may not be indicated if available width of keratinized mucosa is limited prior to implant surgery. Two techniques to preserve keratinized peri-implant mucosa (Punch Reposition Technique and Topical Flap Technique) are presented and indications outlined. Appreciation of soft tissue conditions as well as functional and esthetic consequences of mucosal deficiencies (mucosal-driven approach) is recommended to supplement bone- and prosthetic-driven considerations in guided oral implant placement (Trinity Approach).

Scope.To demonstrate guided implant placement and the application of fixed, implant-supported prosthetic restorations with a fully digital workflow.Methods.Over a 2-year period, all patients with partial edentulism of the posterior maxilla, in need of fixed implant-supported prostheses, were considered for inclusion in this study. The protocol required intraoral scanning and cone beam computed tomography (CBCT), the superimposition of dental-gingival information on bone anatomy, surgical planning, 3D-printed teeth-supported surgical templates, and modelling and milling of polymethylmethacrylate (PMMA) temporaries for immediate loading. After 3 months, final optical impression was taken and milled zirconia frameworks and 3D-printed models were fabricated. The frameworks were veneered with ceramic and delivered to the patients.Results.Fifteen patients were selected for this study. The surgical templates were stable. Thirty implants were placed (BTK Safe®, BTK, Vicenza, Italy) and immediately loaded with PMMA temporaries. After 3 months, the temporaries were replaced by the final restorations in zirconia-ceramic, fabricated with a fully digital process. At 6 months, none of the patients reported any biological or functional problems with the implant-supported prostheses.Conclusions.The present procedure for fully digital planning of implants and short-span fixed implant-supported restorations has been shown to be reliable. Further studies are needed to validate these results.
