[Mechanical properties of metal-ceramic systems from nickel-chromium and cobalt-chromium alloys].
BACKGROUND/AIM Metal-ceramic bond strength and alloys' elastic modulus clearly determine the potential of alloy application, because the ceramic integrity during mastication depends on these two characteristics. The aim of this study was to evaluate metal-ceramic bond strenght and elastic modulus of cobalt-chromium alloys in making porcelain-fused-to-metal restorations, regarding the applicatio...
متن کاملComparative Evaluation of Metal-ceramic Bond Strengths of Nickel Chromium and Cobalt Chromium Alloys on Repeated Castings: An In vitro Study
BACKGROUND Recasting the base metal alloys is done as a routine procedure in the dental laboratories whenever there is casting failure or to decrease the unit cost of a fixed partial denture. However, this procedure may affect the metal ceramic bond. Furthermore, it is unclear, as to which test closely predicts the bond strength of metal-ceramic interface. The aim was to compare the bond streng...
متن کاملEvaluation of the Effect of recasting Nickel-chromium Base Metal Alloy on the Metal-ceramic Bond Strength: An in vitro Study.
AIM The aim of this study was to evaluate the effect of recasting base metal alloy on the metal-ceramic bond strength. MATERIALS AND METHODS A total of 60 test samples were prepared from new and recast nickel-chromium alloy and divided into six groups. In group A0, test samples were prepared from 100% new alloy. Groups A1, A2, A3, A4, and A5 were prepared from 50% new alloy and 50% casting re...
متن کاملShear Bond Strength of Porcelain Veneering to Nickel-Chromium, Chromium-Cobalt, Zirconia and Lithium Disilicate
Background and Aim: High chipping rates of the veneering porcelain in zirconia ce-ramic restorations have been reported in many clinical studies. However, information on the bonding behavior of veneering porcelain to zirconia and lithium disilicate frameworks is limited. The purpose of this study was to evaluate the bond-ing strength of porcelain veneering to zirconia, lithium disilicate, nicke...
