Effect of Opaque Porcelain Thickness Bond Strength of Porcelain to Ni-Cr Alloys
Objectives: Metal-ceramic restorations are the standard by which all esthetic restorations are measured. Fracture of dental restorations is a multifactorial problem, which is serious and costly. Debonding of porcelain from metal substructure and the bond strength depend on many factors. The purpose of this study was to determine whether or not the opaque porcelain thickness has a significant ef...
متن کاملBond strengths of porcelain to cobalt-chromium alloys made by casting, milling, and selective laser melting.
STATEMENT OF PROBLEM Cobalt-chromium (Co-Cr) alloys have been widely used for metal-ceramic fixed prostheses and can be fabricated using conventionally cast or new computer-aided technology. However, the effect of different manufacturing methods on the metal-ceramic bond strength needs further evaluation. PURPOSE The purpose of this in vitro study was to evaluate the metal-ceramic bond streng...
متن کاملEffect of Casting Temperature and Atmosphere on Castability of Ni-Cr Alloys: A Comparative Study with Direct Flame Casting Method
The purpose of this study was to compare the effect of casting temperature and atmosphere on the castability of three Ni-Cr alloys against direct flame casting method. Vera Bond (VB), Vera Bond 2 (VB2) and Wiron 99 (W99) were cast at three temperatures: VB and VB2 (1310 °C, 1340 °C and 1370 °C); W99 (1400 °C, 1430 °C and 1460 °C) in atmosphere, vacuum and direct flame. Each alloy was cast in se...
متن کاملComparison of the Effect of Three methods of Porcelain Surface Treatment on Shear Bond Strength of Composite to Porcelain
Background and Aim: Several methods are available for intraoral repair of chipped porcelain restorations by composite resin. Also, there is still controversy regarding the best method of porcelain repair in terms of bond strength and cost effectiveness. This study aimed to compare three methods of porcelain surface treatment on shear bond strength (SBS) of composite to porcelain. Materials a...
