除了力学性能、生物相容性、耐腐蚀性能和成本外 ,对于一种潜在的牙科材料而言其铸造成型性也影响着该材料最终能否得到应用。在义齿件方面以牙冠件最为常见 ,合金必须具有良好的铸造性能才能铸出完整的牙冠。在前期新型牙科用Ti合金开发工作基础上 ,试验采用纯钛铸造系统制备出了新型牙科用Ti合金牙冠 ,经肉眼观察及X光检查 ,表明不存在表面和内部铸造缺陷 ,牙冠合格 ,能够满足义齿件铸造成型要求 In addition to its mechanical properties, biocompatibility, corrosion resistance and cost, its casting formability for a potential dental material also influences the end-use of the material. Denture parts in the crown to the most common parts, the alloy must have good casting properties in order to cast a complete crown. Based on the development of the new dental Ti alloy, a new Ti alloy dental crown was prepared by the pure titanium casting system. The naked eye and X-ray examination showed that there were no surface and internal casting defects, Denture casting to meet the casting requirements
