Sintered glass-ceramics for dental applications

Abstract

Sintered glass-ceramics are very important to the development of biomaterials for restorative dentistry. The following systems have shown to be particularly suitable: SiO₂-Al₂O₃-Κ₂O (leucite), SiO₂-Al₂O₃-Κ₂O-CaO-P₂O₅-F (leucite,apatite), SiO₂-Al₂O₃-CaO-P₂O₅-F (apatite), Li₂O-SiO₂ (lithiumdisilicate) and SiO₂-P₂O₅-Li₂O-ZrO₂ (ZrO₂ crystals). The principles involved in developing materials of this kind and the applications of these materials will be shown in the following survey.
