marginal adaptation of spinell inceram and feldspathic porcelain laminate veneers
background: this in vitro study investigated the marginal fit of two porcelain laminate veneers to help the selection of more accurate veneers in discolored teeth. materials and methods: thirty impressions of metal master die created from the prepared labial surface of an acrylic maxillary central incisor were made and poured with type iv stone. the dies were distributed into test groups (n = 1...
متن کاملIn vitro analysis of the marginal adaptation and discrepancy of stainless steel crowns
Aim: The purpose of the study was to assess the marginal adaptation and discrepancy of SSC's. Differences in adaptation and discrepancy between the four surfaces (mesial, lingual, distal, and buccal) were evaluated. Methods: The placement of stainless steel crowns were completed on a phantom head in accordance with the clinical technique. The ideal tooth preparation was made and this 'master to...
متن کاملSurface treatment of feldspathic porcelain: scanning electron microscopy analysis
PURPOSE Topographic analysis of treated ceramics provides qualitative information regarding the surface texture affecting the micromechanical retention and locking of resin-ceramics. This study aims to compare the surface microstructure following different surface treatments of feldspathic porcelain. MATERIALS AND METHODS This in-vitro study was conducted on 72 porcelain discs randomly divide...

15 صفحه اولMarginal 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...
