Statement of problem Ceramic restorations are popular because of their excellent optical
properties. However, failures are still a major concern, and dentists are confronted with the …

Objective Dental all-ceramic restorations of zirconia, with and without an aesthetic veneering
layer, have become a viable alternative to conventional metal-ceramic restorations. The aim …

PURPOSE The aim of the study was to evaluate and compare the fracture resistance and
modes of fracture of monolithic zirconia crowns with two preparation designs. MATERIALS …

Bilayer zirconia restoration is one of the most commonly used restorations in dental practice,
but the high frequency of the cohesive/adhesive fracture of veneered porcelain is still a …

PURPOSE To evaluate and compare the effect of different materials and techniques on the
shear bond strength of veneering ceramic materials to zirconia. MATERIALS AND …

Purpose: To investigate the influence of occlusal interference using finite element analysis
(FEA). Materials and Methods: The FEA model designed for this study centered on an all …

Aim: To compare the fracture resistance and the mode of failure between monolith second-
generation zirconia and bilayered first-generation zirconia single crowns cemented by resin …

Brushing with bonded abrasives is a flexible finishing process used to reduce the roughness
of technical surfaces. Although industrially widespread, especially for the finishing of metallic …

The present study evaluated the average (Ra) and total (Rz) roughness, crystallography
(XRD), flexural strength (FS), and Weibull modulus (m) of a monolithic zirconia subjected to …

Objective The purpose of this study was to evaluate the influence of the connector area on
the chipping rate of the VM9 veneering ceramic in a 4-unit yttria-stabilized tetragonal …
