Review on dental ceramics grinding

Dental ceramic restorative materials take a dominant place due to the advantages such as excellent biocompatibility, unique aesthetic and stable chemical properties.However, complex surface characteristics and hard-brittle properties of dental ceramic restorative materials caused difficulties in the computer aided design/computer aided making (CAD/CAM) processing and subsequent grinding, such as complicated craft, high failure rate and surface damage of dental ceramics.Thus, it is of great importance for reducing material damage to fully understand the special grinding tools and their performance and to optimize the parameters.Methods and tools of denture processing are introduced, as well as the removal mechanism, grinding force and grinding surface quality of dental ceramic restorative materials.In the end, main directions for further developing are put forward.
