铸造陶瓷冠具有较金瓷冠技术相对简单的优点。在结晶化和着色时需热处理,本文探讨了热处理对磷灰石铸造陶瓷冠的尺寸改变和变形的影响。材料和方法:①代型:硬质不锈钢代型,做成类似下颌后磨牙全冠预备体的形态,锥度4℃。②蜡型:采用嵌体蜡,在80℃左右温度下堆加,加压(15kg/cm~2),维持5分钟而制得。放置于室温2小时以上让蜡内剩余应力释放。12mm长的铸道插于蜡型(牙合)面中央,从代型
Casting ceramic crowns has the advantage of being relatively simpler than gold ceramic crowns. In the crystallization and coloring heat treatment, the paper discusses the heat treatment on the size of the apatite ceramic crown deformation and deformation. Materials and methods: ① generation: hard stainless steel substituting, made similar to the mandibular premolars after molar morphology, taper 4 ℃. ② wax type: using inlay wax, heap temperature at about 80 ℃, pressure (15kg / cm ~ 2), maintained for 5 minutes and prepared. Allow to stand for more than 2 hours at room temperature to release the residual stress in the wax. 12mm long cast inserted in the wax type (occlusal) face center, from the generation
