摘　　要：目的:分析不同植入部位、不同植入时间微小种植体支抗的脱落的情况,寻找导致微小种植体脱落的最可能原因,以利于临床工作需要。方法:记录176例患者植入的349枚微小种植体植入部位、植入时间及其中脱落的29枚微小种植体的植入部位、植入时间并进行统计分析。结果:植入总成功率为91.6%。植入在腭侧的19枚,及植入在上下颌两侧第二前磨牙近中区域的28枚微小种植体均未见脱落;微小种植体上下颌脱落率有显著性差异;不同年份微小种植体脱落率有显著性差异。结论:植入手术操作是影响微小种植体植入成功率的最主要因素。Objective To find the most possible contributing factors for abscission of Mini-implant, we analyzed the abscission of Miniimplant anchorage in the different position and different time. Methods The data of implantposition and implanttime of 349 Miniimplants in jaw of 176 patients and implant-position and implanttime of 29 abscising Miniimplants among them were recorded and statistically analyzed. Results We had 91.6% success rate in implanting.Abscission hasn＇t been record in regions of the palate,which implanted 19 miniscrews,and regions between the mesial of the second premolar in maxillary and mandible,which implanted 28 miniscrews.There were significant differences in the abscising rate between maxillary and mandible and between different times. Conclusion The most possible contributing factors of success implanting rate is operation itself.
