摘　　要：目的：通过对微螺钉种植体在正畸支抗中的稳定性研究,为临床提供理论依据。方法：按微螺钉种植体标准操作规程对80例各类错牙合畸形患者采用直丝弓配合自攻型微螺钉种植体进行矫治,共种植微螺钉216枚,负载期为8-12个月,评价各个临床变量对微螺钉种植体稳定性的影响。结果：微螺钉种植体成功率为93.5%,下颌平面角高低、微螺钉直径、口腔卫生状况对微种植钉稳定性影响明显,而微种植钉的定位及加力情况对微种植钉稳定性无显著影响。结论：选择较粗的螺钉,对下颌平面角较高的患者采取谨慎设计,维持好的口腔卫生是微螺钉种植成功及能否稳定行使功能的关键。Objective：To support the solid theoretical for clinical application of microbolt implant anchorage based on the study on the stability of microbolt implant in anchorage.Methods：Following the standard proceduce of microbolt anchorage implant,the straight wire arch diorthosis combined with microbolt anchorage implant was utilized to treat 50 cases of diverse malocclusion.Totally,135 microbolt were implanted to evaluate the effect of the clinical variables to the stability of the microbolt anchorage implant;every microbolt was capable to work on 8 to 12 months.Results：The success ratio of microbolt implant was 95.6%.The important factors to affect the stability of microbolt anchorage implant included mandibular plane angle,the diameter of microbolt and the situation of patients′ oral health.And there was no significant effect concerned with the locations where the microblots were implanted and the stress distributions.Conclusions：Choosing the thick size microblots,carefully designing especially for the patients with a large mandibular plane angle,accurately following the operation procedure,and maintaining the oral health are all the critical factors to the successful implant and stable operation of the microbolt implant.
