The pure titanium cast frameworks were made using an arc-melting pressure and vacuum casting apparatus invented by Sato, and an experimental investment material. The salient features of the method and the cast frameworks were as follows: 1. The casting apparatus used was capable of making both complete and partial denture frameworks with pure titanium. It reduced casting errors and the interaction between titanium and the casting mold, producing less porous casted frameworks with a smooth surface. 2. The experimental investment material made a firm heat-resistant investment model with a smooth surface. It showed appropriate expansion and also excellent strength at room temperature after the burn out of the wax pattern. 3. The titanium casted frameworks fitted to the model and the oral cavity closely, and yielded satisfactory clinical results in more than 15 patients.
纯钛铸造支架采用佐藤发明的电弧熔炼压力和真空铸造设备以及一种实验性包埋材料制成。该方法及铸造支架的显著特点如下：1. 所使用的铸造设备能够用纯钛制作全口和局部义齿支架。它减少了铸造误差以及钛与铸模之间的相互作用，使铸造支架气孔更少且表面光滑。2. 实验性包埋材料制作出表面光滑且耐热性强的包埋模型。在蜡型熔失后，它显示出适当的膨胀以及在室温下优异的强度。3. 钛铸造支架与模型和口腔贴合紧密，在超过15例患者中取得了满意的临床效果。
