The invention discloses a kind of customized type fixed denture care of patients underwent ceramic veneer, mould teeth restoration form in order to the porcelain porcelain direct heap of powder that leucite is main component, the constituent of this care of patients underwent ceramic veneer includes: SiO 2 ,Al 2 O 3 ,K 2 O,Na 2 O,Li 2 O,BaO,B 2 O 3 ,CaO,Sb 2 O 3 ,ZrO 2 ,SnO 2 ,CeO 2 ,F,TiO 2 The manufacture method of this care of patients underwent ceramic veneer is: make the high temperature resistant die of tooth body, and it is carried out pretreatment, die immersion, it is possible to carry out porcelain and sintering, successively coat successively and combine porcelain, body porcelain, cut porcelain, the sintering of different temperatures will be carried out every time after porcelain in sintering furnace, after sintering, form can slightly be made polishing finishing, last glazing, again enter stove sintering, finally removing Die material, take off veneer, the overall thick of veneer is about 0.5 0.7mm.This veneer histocompatibility is good, stable chemical performance, High anti bending strength, and color and luster is adjustable to be coordinated with natural teeth, and the clinical practice for oral cavity Ceramic prosthesis lays the first stone. |
