“…The preparation of the guiding surfaces mostly depends on the experience and ability of the dentist [ 15 ]. Friction retention or retention created from contact on guiding surfaces is an excellent source of retention force in the prosthesis, but often cannot be accomplished, because the leading surfaces must always be parallel.…”

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.

“…2 Once approved, silicone matrices of the waxing can be used to define the tooth preparation. [12][13][14][15][16][17][18][19][20] Limitations of this conventional workflow include the time and effort needed to produce a conventional diagnostic waxing and trial restoration and their associated costs. One further limitation is the predictability of the transfer of this plan to the patient.…”

Recent developments in digital technologies in dentistry have led to significant changes of treatment concepts in prosthodontics. Optical scanning allows digitalization of the initial clinical situation, delivering virtual files of the initial status of the dentition in the standard tessellation language (STL) format. The STL files can be input into a computer-aided design (CAD) software program and analyzed. 1 Digital diagnostics, including digital waxing and trial restorations, can then be performed. Subsequently, the type and design of the planned restorations can be exported as digital files and milled or printed by means of computer-aided manufacturing (CAM) technology to fabricate CAD-CAM trial restorations. 2 After tooth preparation, the planned restorations can be fabricated with the CAD-CAM technology.Different types of ceramic and composite resin materials have been developed for fabrication, opening up new prosthetic treatments. Less-invasive restorations, such as veneers, onlays, and partialcoverage crowns, can be milled from ceramic or composite resin materials and cemented with adhesive material as an alternative to conventional fixed prostheses. 3,4 Studies have shown 5,6 that conventional preparation of complete coverage ceramic crowns necessitates anterior or posterior tooth reduction ranging between 40% and 70%. In contrast, tooth reduction for ceramic veneers on maxillary central incisors ranges between 17% and 30%. 5,6 Extensive tooth preparation can cause hypersensitivity and pulpal damage. [7][8][9][10][11] For this reason, and consistent with the development of materials and adhesive dentistry, current prosthodontic concepts have proposed less-invasive restorations before preparing a crown.
