摘要
在建立基牙牙冠数学模型和卡环数学模型的基础上,并分析卡环不锈钢丝的金属功能,选择应用冷冲模制作工艺,并研制出正型卡环机,制作出系列商品化成品卡环已用于临床。
Based on the establishment of mathematical models of abutment crown and clasp,and analyze the function of the metal clasp stainless steel wire,select the application of Die production process,and develop a positive clasp machine,to create a series of commercialization of the finished card ring.And it has been used clinically.
