Influence of cervical finish line type on the marginal adaptation of zirconia ceramic crowns.
The current study evaluated the effect of different cervical finish line designs on the marginal adaptation of a zirconia ceramic. Four different marginal finish lines (c: chamfer, mc: mini-chamfer, fe: feather-edge and s: rounded shoulder) were prepared on phantom incisors. Die models for each preparation group (N = 28, n = 7 per finish line design group) were made of epoxy resin. Y-TZP (ICE Z...
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 کاملThe Effect of Different Marginal Designs on the Fracture Resistance of Monolithic Zirconia Crowns
Abstract Background and Aim: One of the major problems of all ceramic restorations is their probable fracture against the occlusal force. The aim of the present in vitro study is to compare the effect of three marginal designs (shoulder, sloped shoulder, chamfer) on the fracture resistance of monolithic zirconia crowns. Materials and methods: In this in vitro study, three PEEK dies with cham...
متن کاملChairside Fabrication of an All-Ceramic Partial Crown Using a Zirconia-Reinforced Lithium Silicate Ceramic
The chairside fabrication of a monolithic partial crown using a zirconia-reinforced lithium silicate (ZLS) ceramic is described. The fully digitized model-free workflow in a dental practice is possible due to the use of a powder-free intraoral scanner and the computer-aided design/computer-assisted manufacturing (CAD/CAM) of the restorations. The innovative ZLS material offers a singular combin...
متن کاملEvaluating The Opacity of Two Super high Translucent Zirconia and Lithium Disilicate Reinforced Glass Ceramic
Abstract Background and Aim: The opacity of dental ceramics has important role in final appearance of all ceramic restorations. opacity of super high translucent zirconia is not clearly determined.The aim of this study was evaluating the opacity of two super high translucent zirconia (zolid fx and DD cubeX2 ) and lithium disilicate reinforced glass ceramic(IPS e.max CAD LT). Materials and Metho...
