“…This takes advantage of the software precision in measurements and quantification. On the 3D models, volumes and distances can be precisely measured [19], and in the dental practice, analysis of tooth preparation can occur prior to prosthesis fabrication. In some instances, where the tooth preparation is not ideal or restoration thickness is minimal, modifications of the tooth preparation can be recommended to reduce the risk of mechanical failure of the prosthesis.…”

In prosthodontics, conventional methods of fabrication of oral and facial prostheses have been considered the gold standard for many years. The development of computer-aided manufacturing and the medical application of this industrial technology have provided an alternative way of fabricating oral and facial prostheses. This narrative review aims to evaluate the different streams of computer-aided manufacturing in prosthodontics. To date, there are two streams: the subtractive and the additive approaches. The differences reside in the processing protocols, materials used, and their respective accuracy. In general, there is a tendency for the subtractive method to provide more homogeneous objects with acceptable accuracy that may be more suitable for the production of intraoral prostheses where high occlusal forces are anticipated. Additive manufacturing methods have the ability to produce large workpieces with significant surface variation and competitive accuracy. Such advantages make them ideal for the fabrication of facial prostheses.

“…Microcomputed tomography is an available and commonly used technology in dental materials research with its use being described for over 20 years. When processed by appropriate software, the obtained images can be combined to generate three‐dimensional models, and to identify and dissociate materials of dissimilar densities . This technology was used in the presented workflow to gather useful information for the fabrication of a highly customized restoration, following natural dentin and enamel morphology.…”

“…When processed by appropriate software, the obtained images can be combined to generate three-dimensional models, and to identify and dissociate materials of dissimilar densities. [6][7][8][9][10][11][12][13] This technology was used in the presented workflow to gather useful information for the fabrication of a highly customized restoration, following natural dentin and enamel morphology. Annual debonding rates of 2.89 for metal-ceramic, 4.17 for metalacrylic, 1.72 for fiber-reinforced composite, 1.42 for zirconia and no debondings for glass-infiltrated and glass-reinforced ceramic frameworks have been reported.…”

The paper presents selected methods of assessment of tooth preparation based on the literature, among others, computer software cooperating with scanners, e.g. Preppr, DentSim, PREPassistant, E4D Compare, PrepCheck and Simodont Dental Trainer. During tooth preparation for prosthetic restorations, it is necessary to create sufficient space, which will allow the technician to construct an aesthetic and durable restoration. Hard tissues should be prepared very sparingly, while at the same time providing retention and stabilization as well as marginal integration for future restoration. The anatomy of the occlusal surface should be preserved, and the axial walls reduced to the proper thickness to obtain an optimal degree of convergence angle, which equals 6 o. The most common errors in tooth preparation for crowns are inadequate reduction of the occlusal surface, the lack of functional cusp bevel and incorrect finish line width. The occlusal surface is excessively reduced on average by 15%, whereas the width of the finish line on the vestibular surface is about 28% too small. The results of the convergence angle measurement exceed three times the recommended values in the literature, which can adversely affect the retention of restoration.
