the influence of porcelain firing cycle on marginal fitness of electroformed metal-ceramic crowns
background and aim: metal ceramic restorations are widely used in crowns. the marginal fitness of these artificial crowns is prone to alteration during the firing cycle of porcelain. gold electroformed metal-ceramic restorations have been introduced as alternatives to conventional metal-ceramic restorations. however little is known about the relationship between procelain firing procedures and ...

15 صفحه اولMarginal and Internal Crown Fit Evaluation of CAD/CAM versus Press-Laboratory All-Ceramic Crown
The aim of this article is to evaluate marginal and internal fit between the all-ceramic crowns manufactured by the conventional press-dental laboratory and CAD/CAM systems. Methods: Tooth #14 was prepared per standard specification to receive an all-ceramic crown restoration. Forty-five prep tooth #14 were duplicated and randomly divided into three groups (n=15). All-ceramic CAD/CAM system (Gr...
متن کاملMarginal Strength of Collarless Metal Ceramic Crown
Metal ceramic restorations have been implicated for the discoloration in area of labiogingivalmargin. Attempts to rectify this, by altering the design of metal frameworkswill lead to decrease in fracture strength atmargin. This in vitro study compared the fracture strength at margins of metal ceramic crowns cemented to metal tooth analogs. Crowns evaluated with different marginal configurations...
