The influence of the resin- based cement layer on ceramic-dentin bond strength

, , , and | June 3rd 2021

 -

The purpose of the study was to measure the cement thickness obtained when ceramic rods were luted to dentin and to analyze the relation between cement thickness and the previously published tensile bond strength of similar test specimens. In addition, the ISO standard 4049:2019 method was used to determine the film thickness of the used […]
Scaffold-Free Engineering of Human Cartilage Implants

Despite new strategies in tissue engineering, cartilage repair remains a major challenge. Our aim is to treat
patients with focal lesions of articular cartilage with autologous hyaline cartilage implants using a scaffold-free approach. In this article, we describe experiments to optimize production of scaffold-free cartilage discs.
Residual stress in bench- and furnace-cooled porcelain-fused to zirconia appliances

 -

A new study of veneered zirconia shows that the magnitude of residual stresses can only be estimated reliably from the manufacturers’ thermal expansion coefficients if the veneered prosthesis is cooled slowly after the final firing.
Thermal induced deflection of a porcelain–zirconia bilayer: Influence of cooling rate
