发明名称 Glass-infiltrated sapphire/alumina composites for tooth restorations and preparation method thereof
摘要 <p>The present invention relates to a glass-infiltrated sapphire/alumina compound for tooth restoration and a method for preparing the same. According to the present invention, when compared to a conventional glass-filtrated ceramic compound, the glass-infiltrated sapphire/alumina compound for tooth restoration has a remarkably excellent light transmission property, and the glass water permeates into the gaps between the pores of a porous preform (preform) during a sintering and heat treatment process so that no shrinkage is occurred, thereby having a net-shape property with high accuracy size. Thus, the accuracy size and mechanical strength of a crown used for treatment are excellent, thereby being able to be used as a coping material for the core. Also, the glass-infiltrated sapphire/alumina compound is able to be used as a material for crowns including inray, onray, veneer, and crowns; thereby being useful as a glass filling material for various dental compounds.</p>
