[en] Recent introduction of computer-aided design/computer-aided manufacturing (CAD/CAM) monolithic zirconia dental prostheses raises the issue of material Low Temperature Degradation (LTD), a well-known problem with zirconia hip prostheses. This phenomenon could be accentuated by masticatory mechanical stress. Until now zirconia LTD process has only been studied in vitro. The main objective of this study was to evaluate in vivo LTD of second-generation zirconia restorations using an original protocol including ex vivo analyses of zirconia crystalline microstructure, focusing on the effect of occlusal stress and glaze protection.
