STATEMENT OF PROBLEM Intraoral scanners may use proprietary acquisition and manufacturing processes. However, limited information is available regarding their accuracy, their precision, and the influence that refraction or coating may have on their output. PURPOSE The purpose of the study was to evaluate the scanning accuracy and precision of 4 intraoral scanners and to assess the influence o...

Dr. Duret first introduced the CAD/CAM concept to dentistry in 1973 in Lyon, France in his thesis entitled Empreinte Optique, which translates to Optical Impression. The concept of CAD/CAM systems was further developed by Dr. Mormann, a Swiss Dentist, and Mr. Brandestini, who was an electrical engineer. 8 CEREC was the first commercially available digital impression system for use in the field ...

The purpose of this study was to evaluate the effect of changes in the tapering angle of inlay casting, adhesive gap and cavosurface margin on the cavity wall adaptability of the inlay made by the dental CAD/CAM CEREC 2 system. Designed inlay castings were fabricated at three different tapering angles: 0, 3, and 6 degrees. Adhesive gap of 0, -50, -100 microns and adhesive gap of 0 micron combin...

PURPOSE This systematic review sought to determine the long-term clinical survival rates of single-tooth restorations fabricated with computer-aided design/computer-assisted manufacture (CAD/CAM) technology, as well as the frequency of failures depending on the CAD/CAM system, the type of restoration, the selected material, and the luting agent. MATERIALS AND METHODS An electronic search from...

AIM To achieve satisfactory aesthetic appearance of ceramic veneers food debris retention and plaque formation, resulting in possible irritation of surrounding tissues, should be avoided. It is, therefore, necessary to decrease the roughness of ceramic surfaces as much as possible. The aim of this study was to evaluate surface roughness of ceramic veneers after polishin15038787 g with four diff...

Aim: As a result of large coronal destruction in endodontically treated teeth, significant losses occur the dentin tissue around pulp and need for prosthetic treatment occurs. In this case series, endocrown applications produced single session with CAD/CAM system are presented as an alternative to crown restoration traditionally applied premolar molar teeth excessive destruction.
