既往采用锤造无缝冠法制作后牙固定义齿。此法不仅工序复杂,患者就诊次数多,而且当咀嚼力过大时,焊接处易发生断裂。为此,我院自拟固定义齿一板成形法,经多年临床应用500例,使用5年左右者无一例失败,证明效果良好。制作方法:①按常规取印模,灌注工作模和对颌模,并在上下颌模型上划出(牙合)对线,修整基牙的龈边缘。②在阳性工作模上,将缺失牙处填塞软蜡,按咬(牙合)关系雕刻出缺失牙的逼真模型,在基牙
Past use of hammer-made seamless crown production denture fixed denture. This method is not only complicated process, the patient visits more often, and when the chewing force is too large, the weld prone to fracture. To this end, our hospital self-fixed denture plate forming method, after many years of clinical application of 500 cases, the use of about 5 years without a failure, prove good. Production methods: ① according to conventional take impression mold, perfusion working mode and jaw mode, and in the jaw model drawn (occlusion) on the line, trimming abutment gingival margin. ② in the positive working mode, the missing tooth wax filling Department, according to bite (occlusion) relationship carved out of the realistic model of missing teeth in the abutment
