Abstract
There is an increasing demand for dental implant treatment. Currently, dental implant crowns are formed by cutting semi-sintered ceramics (composite functional ceramics material) and then sintering the ceramics at a high temperature. Hence, there are some concerns that the form accuracy of the workpiece cannot be maintained. Meanwhile, it is usually difficult to machine sintered ceramics with high precision and high efficiency. In this study, we investigated the basic grinding characteristics of dental ceramics due to lack of data on wheel wear, removal quantity, surface property, etc. The results showed that sintered ceramics can be ground with high precision and efficiency.
