钛合金与钴铬合金铸造支架的对比研究

Comparison Study of Ti-75 Alloy and Co-Cr Alloy Casting Denture Framewonk

目的 :对比分析Ti- 75合金和Co6 5Cr2 8Mo7合金的力学性能和物理性能 ,为义齿支架的合理选材和设计提供依据 .方法 :对两种合金进行性能测试 ,显微组织观察及临床试验 .结果 :Ti- 75具有更优良的延展性 ,且密度低得多 .结论 :推荐优先选用Ti- 75作为义齿支架材料 。

Objectives: Comparison of mechanical and physical properties between alloys of Ti-75 and Co65Cr28Mo7 is made for better design and choice of denture framework. Methods: Property measurement, microstructure analysis and clinical test were carried out. Results: Except density and ductility, there is no considerable difference in mechanical properties between the two alloys. Conclusion: Ti-75 is recommended as preferential denture framework material for thinner design.
