Pre-sintered ceramic block used for dental restoration, its manufacturing method and its application

摘要

Examples of the present application disclose a pre-sintered ceramic block used in a dental restoration. The pre-sintered ceramic block does not contain a crystalline phase and has a Vickers hardness of 0.5-2 GPa. Because of its low hardness and clearly lower than the ceramic block containing the lithium metasilicate crystal phase, the pre-sintered ceramic block provided by the present application can not only employ dry machining when machined into the shape of a dental restoration, but also at the same time Wet machining can also be employed.
