摘　　要：通过预测铸造参数对铸造缺陷的影响,应用有限元模拟分析软件ProCAST模拟铸造纯钛义齿支架的充型及凝固过程。结果表明:铸造成功率与铸造参数相关;通过对原铸造参数的改进,铸圈温度为150℃,铸造压力为0.2MPa时,保证了纯钛义齿支架的质量。Mold- filling and solidification process in pure titanium denture frameworks investment are performed using the finite element analysis software ProCAST before predicting the effects of the casting parameters on the casting defects. The results show that Casting parameters influence the success rate of casting; Through optimizing and quantify the optimal casting parameters, of which casting ring temperature is 150 o C and casting pressure is 0.2MPa , sound frameworks were made.
