Marginal 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...
متن کاملMarginal fit of all-ceramic crowns fabricated using two extraoral CAD/CAM systems in comparison with the conventional technique
OBJECTIVE The purpose of this study was to determine the effect of two extraoral computer-aided design (CAD) and computer-aided manufacturing (CAM) systems, in comparison with conventional techniques, on the marginal fit of monolithic CAD/CAM lithium disilicate ceramic crowns. STUDY DESIGN This is an in vitro interventional study. PLACE AND DURATION OF STUDY The study was carried out at the...
متن کاملInternal fit of two all-ceramic systems and metal-ceramic crowns
OBJECTIVES The aim of this study was to investigate the internal fit (IF) of glass-infiltrated alumina (ICA--In-Ceram Alumina), yttria-stabilized tetragonal zirconia polycrystals (Y-TZP--IPS e.max ZirCAD), and metal-ceramic (MC--Ni-Cr alloy) crowns. MATERIAL AND METHODS Sixty standardized resin-tooth replicas of a maxillary first molar were produced for crown placement and divided into 3 grou...
متن کاملClinical marginal and internal gaps of zirconia all-ceramic crowns.
PURPOSE Marginal and internal gaps of NobelProcera crown zirconia were clinically evaluated using silicone materials. MATERIALS AND METHODS Ninety-one crowns were examined before final cementation, and white and black silicone materials were used to record the marginal and internal fit. The silicone materials were sectioned bucco-lingually and mesio-distally, and the thickness of the silicone...
متن کاملMarginal and internal adaptation of zirconium dioxide ceramic copings and crowns with different finish line designs.
The present study evaluated the marginal and internal adaptation of single-tooth zirconium dioxide (ZrO2) ceramic copings or crowns with three different finish line designs. Twenty-four steel dies were prepared for maxillary central incisor crowns with the following finish line designs: shoulder (S), rounded shoulder (RS), and chamfer (C) preparations. Twenty-four standardized ZrO2 ceramic copi...
