Hydrothermal degradation of a 3Y-TZP translucent dental ceramic: A comparison of numerical predictions with experimental data after 2 years of aging.

Objectives: The purpose of the study was to assess the hydrothermal resistance of a translucent zirconia with two clinical relevant surface textures by means of accelerated tests (LTD) and to compare predicted monoclinic fractions with experimental values measured after two years aging at 37°C.

Methods: Polished (P) and ground (G) specimens were subjected to hydrothermal degradation by exposure to water steam at different temperatures and pressures. The t-m phase transformation was quantified by grazing incidence X-ray diffraction (GIXDR).

Three- to nine-year survival estimates and fracture mechanisms of zirconia- and alumina-based restorations using standardized criteria to distinguish the severity of ceramic fractures.

Objectives: The aims of this study were set as follows: 1. To provide verifiable criteria to categorize the ceramic fractures into non-critical (i.e.

TiNOx coatings increase human primary osteoblasts proliferation independently of the substrate: a short report.

Introduction: When applied onto SLA titanium, Titanium Nitride Oxide (TiNOx) coatings are known for their stimulating effect on osteoblast proliferation while maintaining a high degree of differentiation.

Objective: To determine whether the stimulating effect of TiNOx coatings is or is not dependent of the metal substrate.

Methods: A TiNOx coating was deposited on roughened stainless steel (SS-SLA-TiNOx).

TiNOx coatings on roughened titanium and CoCr alloy accelerate early osseointegration of dental implants in minipigs.

Introduction: Titanium nitride oxide (TiNOx) coatings are known for their biocompatibility, hardness and high resistance to corrosion and wear. Further, they can be applied by plasma vapor deposition onto a wide variety of metallic, mineral, or organic substrates. In cell cultures, TiNOx coatings applied onto SLA (sandblasted, large grit, acid etched)-roughened titanium surfaces increased human primary osteoblast proliferation by 1.

Implementation of the "loaded implant" model in the rat using a miniaturized setup--description of the method and first results.

Objective: To miniaturize the "loaded implant" model to permit its application to small rodents. In this model, two titanium implants are placed 8 mm apart with their heads protruding from the skin and are forced together by a dedicated actuator. To assess the effect of (i) the post-implantation healing period and the duration of stimulation and (ii) the intratissular strain level on the microtomographical bone parameters BV/TV, Tb.
