Cast titanium restoration for molars has high biocompatibility and is covered by the Japanese national health insurance. Titanium casting requires specific investment material and casting apparatus. A cast restoration for the mandibular left second molar was fabricated using titanium in this study. A wax pattern fabricated on a definitive cast was invested in calcium aluminate-bonded magnesia investment material. Titanium was cast using an argon gas pressure one-chamber casting apparatus. No defects were observed on the surface and the hole was clearly reproduced. A smooth surface on the restoration was obtained by polishing at low speed. Reproductivity and polishing properties of the titanium restoration fabricated in this study were comparable to those of conventional dental metal restorations.

磨牙用铸钛修复体具有高生物相容性，并受日本国家健康保险的保护。钛铸件需要特定的投资材料和铸造设备。在这项研究中，使用钛制造了下颌左第二磨牙的铸件修复体。在确定的铸件上制作的蜡模被投入铝酸钙粘结的氧化镁熔敷材料中。使用氩气压力一室铸造设备铸造钛。在表面上未观察到缺陷，并且清楚地再现了孔。通过低速抛光获得修复体上的光滑表面。在这项研究中制造的钛修复体的生殖能力和抛光性能与常规牙科金属修复体相当。
