Abstract
Since the late 90s the use of zirconia in dentistry increases, it is used for example for all-ceramic restorations, brackets and implants. This article will deal with all-ceramic restorations. For the production of these restorations many manufacturing steps are necessary: Pre-sintering of the ceramic powder, soft machining (pre-sintered condition), sintering and a pre-processing of the ‘finished’ geometry like hard machining (fully sintered) or grit blasting (GB) in combination with a final staining or veneering step. Most of the steps (excluding soft machining in a pre-sintered condition and sintering) are still carried out manually. All these techniques are associated with the production of flaws in different scales, in conjunction with thermal and residual stresses and phase transformations. This study investigates how those surface and subsurface properties, which arise due to the manufacturing process, influence the bonding between a framework ceramic and a veneering ceramic. This will be investigated by means of a scratch test.
