Customized fixed partial denture porcelain veneer

Abstract

The invention discloses a customized fixed partial denture porcelain veneer. Porcelain powder with leucite as the main ingredient is directly used for paste-on-paste decoration of tooth repair form. The porcelain veneer comprises SiO2, Al2O3, K2O, Na2O, Li2O, BaO, B2O3, CaO, Sb2O3, ZrO2, SnO2, CeO2, F and TiO2. A method for preparing the porcelain veneer comprises the steps of making a high-temperature resistant tooth die, conducting pretreatment and soaking on the die so that porcelain coating and sintering can be conducted, coating combination porcelain, dentin porcelain and cutting porcelain in sequence, conducting sintering in a sintering furnace at different temperatures every time porcelain coating is conducted, conducting form polishing and finishing after sintering, then conducting glazing, conducting sintering in the furnace again, removing the die material, and taking off the veneer with overall thickness of 0.5-0.7 mm. The veneer has high tissue compatibility, stable chemical performance and high breaking strength, the color of the veneer can be adjusted to be matched with natural teeth, and a basis is laid for clinical application of porcelain repair of oral cavity.
