“…33 The use of a fine grit rotary instrument was supported by Li et al 34 who concluded that teeth prepared with finer grit rotary instruments had smoother tooth surfaces, resulting in cast metal crown restorations with better internal adaptation. Taman et al, 35 using mCT, also showed that feldspathic CAD-CAM crowns had lower marginal gaps with preparations done with fine grit diamond rotary instruments than when done with coarse grit diamond rotary instruments.…”

“…The multiple causes and development of NCCLs require comprehensive treatment. Some researchers report the need for orthodontic correction in conjunction with cavity closure [ 47 ]. The use of veneer onlays in conjunction with direct restorations is common [ 48 ].…”

This paper deals with direct restorations of teeth with non-carious cervical lesions (NCCL). NCCL defects are capable of gradual growth and are accompanied by the degradation of the surrounding tissue. Direct restorative treatment, in which the cavity is filled with a cementing agent, is considered to be an accessible and common treatment option. The study included simulations of the teeth without lesions, the teeth with V and U lesions and the tooth-restorative system. Parameterised numerical tooth models were constructed. Two cases with defect depths of 0.8 mm and ~1.7 mm and three variants with fillet radii of the defect end of 0.1, 0.2 and 0.3 mm were considered. The effect of two biomaterials for restorations was studied, namely Herculite XRV (Kerr Corp, Orange, CA, USA) and Charisma (Heraeus Kulzer GmbH, Hanau, Germany). The models were deformed with a vertical load of 100 to 1000 N from the antagonist tooth. The tooth-restorative system was considered, taking into consideration the contact interaction in the interface areas with the tooth tissues. Within the limits of the research, the character of the distribution of the deformation characteristics and their dependence on the level of loading, the depth of the defect and the radius of the curvature of the “wedge” were established.

“…Preparations restored with zirconiaenhanced lithium silicate appear to perform better in sealing the external margin after cyclic fatigue. 25 Tamam et al 26 evaluated the fit of CAD-CAM ceramic restorations following different preparation procedures with micro-CT. In the study, monolithic feldspathic ceramic crowns with a total of 28 anatomical contours were produced for 4 tipodont teeth.…”

Today, the use of micro-computed tomography is becoming widespread in almost every field of dental research. When the national review articles on micro-computed tomography are examined, it is seen that the focus is on endodontic and surgical dental applications. As prosthodontists, our article, which was compiled in order to deepen the specific usage areas of micro-computed tomography applications and to review the studies done in this area, provides information about the use of micro-computed tomography method in prosthetic dentistry. Micro-computed tomography is a powerful in vitro research method. Micro-computed tomography was used; marginal and internal compatibility of restorations, cement spacing of restorations, adaptation of denture bases, accuracy of prosthetic measurements, effects of occlusal irregularities, volumetric changes in teeth due to dental post application, biomechanical evaluation of implant-abutment connection, and compatibility of maxillofacial prostheses.
