Comparative Evaluation of Two Chairside CAD CAM Systems
In the 1950s and 1960s when prototypes of computer aided design (CAD) and computer-aided manufacturing (CAM) were introduced into industrial settings. Early dreamers like Mörmann, Durret and colleagues and Rekow were intrigued by the possibilities of using CAD-CAM in dentistry continued to work, and CAD/CAM systems are now part of everyday dentistry. The success of CAD CAM systems reflects in t...
متن کاملOverview of CEREC CAD/CAM chairside system.
This article describes CAD/CAM technology used in dentistry and different restorative materials used in conjunction with adhesive cementation with particular attention given to the evolution of the CEREC system, as well as various ceramics developed for this system. Advantages and limitations of materials and technique are also discussed.
متن کاملEvaluation of marginal fit and internal adaptation of zirconia copings fabricated by two CAD - CAM systems: An in vitro study
STATEMENT OF PROBLEM Three main factors which determine the success of an All-ceramic restoration are esthetic value, resistance to fracture and third being the marginal fit. Marginal fit and internal adaptation are crucial factors in increasing the longevity of the restoration. Newer and economical CAD CAM systems have been introduced claiming better marginal fit and adaptation of All ceramic ...
متن کاملMarginal discrepancy and microleakage in crown-copings fabricated by three CAD/CAM systems: An in vitro study
The purpose of this study was to evaluate and compare the microleakage and marginal discrepancy of ceramic crown-copings fabricated by three different CAD/CAM systems. Material and methods: Thirty extracted premolars were prepared for complete allceramic crowns with: total convergence 10-degree, 2 mm occlusal reduction, 4.5 mm height, 1.3 mm circular reduction and chamfer marginal preparation. ...
متن کاملMarginal and internal fit of all-ceramic crowns fabricated with two different CAD/CAM systems.
This study evaluated the accuracy of marginal and internal fit between the all-ceramic crowns manufactured by a conventional double-layer computer-aided design/computer-aided manufacturing (CAD/CAM) system and a single-layer system. Ten standardized crowns were fabricated from each of these two systems: conventional double-layer CAD/CAM system (Procera) and a single-layer system (Cerec 3D). The...
