Objectives Clinical data on survival rates reveal that all-ceramic dental prostheses are
susceptible to fracture from repetitive occlusal loading. The objective of this review is to …

Objectives To survey simple contact testing protocols for evaluating the mechanical integrity
of zirconia dental ceramics. Specifically, to map vital material property variations and to …

The limit of applicability of the correlation between the ratio of hardness to elastic modulus
(H/E) of coating systems and their wear resistance has been explored. Experimental …

S100/calgranulin polypeptides are present at sites of inflammation, likely released by
inflammatory cells targeted to such loci by a range of environmental cues. We report here …

A study has been made of the effects of sandblasting on the strength of Y‐TZP and alumina
ceramic layers joined to polymeric substrates and loaded at the top surfaces by a spherical …

Hard and brittle solids with covalent/ionic bonding are used in a wide range of modern‐day
manufacturing technologies. Optimization of a shaping process can shorten manufacturing …

Ceramic-based crowns, particularly molar crowns, can fail prematurely from accumulation of
fracture and other damage in continual occlusal contact. Damage modes depend on …

OBJECTIVES: The purpose of this study was to test in vitro the fatigue and fracture
properties of the Zirconia Everest® core material after being veneered with a sintered or a …

Failure due to fatigue manifests itself in dental prostheses and restorations as wear,
fractured margins, delaminated coatings, and bulk fracture. Mechanisms responsible for …

Threshold damage mechanisms in brittle covalent–ionic solids are outlined. Fracture and
deformation modes are analyzed in terms of classical contact mechanics. Distinctions are …
