| 摘 要： | 为探讨前牙３２１缺失中不同种植基桩数目对Ｎｉ－Ｃｒ合金种植固定桥桥支架适合性的影响，采用三维坐标测量法对３组分别含有１，２，３个种植基桩的五单位双端固定桥试件进行测量。结果显示选择不同的种植基桩数目对同一长度的铸件的精度有差别，含有２个基桩的试件精度最高。固位体的理论边缘间隙值在５０－１５０μｍ，理论浮升量在１００－２５０μｍ。

| Abstract: | Good fitness of osseointegrated frameworks was a key factor to protect implant for function. The purpose of this study was to evaluate the fitness of anterior implant fixed bridge in one-piece casting made of Ni-Cr alloy in different numbers of fixture abutments. The specimens were measured by the three-dimensional measurement system (German Opton uMM550). The results demonstrated that there were statistically significant differences in dimensional changes among one, two or three fixture numbers, the space of retention was 50-150 microns, and the flow of retention was 100-250 microns. |
