Marginal and internal fit of nano-composite CAD/CAM restorations.
OBJECTIVES The purpose of this study was to compare the marginal and internal fit of nano-composite CAD-CAM restorations. MATERIALS AND METHODS A full veneer crown and an mesio-occluso-distal (MOD) inlay cavity, which were prepared on extracted human molars, were used as templates of epoxy resin replicas. The prepared teeth were scanned and CAD-CAM restorations were milled using Lava Ultimate...

background and aims. cad/cam systems facilitate the use of zirconia substructure materials for all-ceramic copings. this in vitro study investigated the marginal and internal fit of zirconia copings made with cad/cam system and slip-casting method. materials and methods. sixteen cad/cam made zirconia copings and 16 slip-cast made zirconia copings were fabricated and cemented with glass-ionomer ...
متن کاملEffect of sintering on the marginal and internal fit of CAD/CAM-fabricated zirconia frameworks.
The aim of this study was to investigate the effect of post-machining sintering on marginal and internal fit of CAD/CAM-fabricated zirconia frameworks. Single crown copings (A: abutment), three-unit bridge frameworks (APA, P: pontic), four-unit bridge frameworks (APPA), and five-unit bridge frameworks (A1P1A2P2A3) were fabricated with raw-stage zirconia blanks using a commercial CAD/CAM system ...

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...
