摘　　要：目的:比较不同种植系统、不同牙位的单个种植牙修复后的人造冠松动率,探讨引起冠松动的因素。方法:对320个单牙种植体进行2年随访,观察2年内冠松动情况,分析引起冠松动的因素。结果:Frailit-2、XIVE系统、BLB系统及IMZ系统松动率分别为1.2%、0%、4.8%及16.7%,前牙及后牙的松动率分别为0.7%、6.4%。结论:对于单个种植牙修复病例,IMZ系统较其它3种种植系统更易导致冠松动,后牙较前牙易出现冠松动,可能与后牙区咀嚼力较大有关。Objective： To compare the crown loosening rate among different implant systems and region in single implant supported dentrue.nethod： 320 single-tooth implants were followed to evaluate the crown loosening rate in two years after restoration.Result： The crown loosening rate for Frailit-2 implants systems,XIVE implants systems ,BLB implant system and IMZ implant systems was 1.2% ,0% ,4.8% and 16.7% respectively. The loosening rate in anterior region and posterior region was 2.1%,6.4% respectively.Conclusion： Restoration in IMZ implant systems have a higher crown loosening rate than the other implant systems for singer-tooth implants. Restoration in posterior region have a higher crown loosening rate than anterior region.
