OBJECTIVES The aim of this study was to evaluate the effect of the airborne-particle abrasion and liner application on the interfacial toughness between veneering porcelain and zirconia core by means of a fracture mechanics test. METHODS Beam-shaped zirconia specimens were sectioned and divided into 4 groups according to different surface treatments as(More)
STATEMENT OF PROBLEM Chipping of veneering porcelain and delamination of a zirconia-veneer interface are 2 common clinical failure modes for zirconia-based restorations and may be partially due to weak interface bonding. The effect of liner on the bond strength of the interface has not been clearly identified. PURPOSE The purpose of the research was to(More)
Few studies have focused on the interface fracture performance of zirconia/veneer bilayered structure, which plays an important role in dental all-ceramic restorations. The purpose of this study was to evaluate the fracture mechanics performance of zirconia/veneer interface in a wide range of mode-mixities (at phase angles ranging from 0° to 90°), and to(More)
PURPOSE The purpose of the study was to verify the finite element analysis model of three-unite fixed partial denture with in vitro electronic strain analysis and analyze clinical situation with the verified model. METHODS First, strain gauges were attached to the critical areas of a three-unit fixed partial denture. Strain values were measured under 300(More)
PURPOSE The aims of this study were to reveal the mechanism of failure of bilayered beams and to assess the thickness ratio effect on the load-bearing capacity of the bilayered beams. MATERIALS AND METHODS Both analytical and finite element analysis methods were used to analyze the stress distributions of bilayered beams subjected to three-point bending(More)
