目的:研究上颌颊侧区微种植支抗的成功率的影响因素。方法:选取2008年1月至2013年12月北京大学深圳医院收治的77例患者,共植入微支抗钉158枚,统计分析影响种植支抗成功的相关因素。结果:158枚钉脱落27枚,成功率83.1%。77名患者中,18名患者有种植钉脱落,成功率81.7%,患者性别、牙齿移动方式、种植钉材质、直径、长度与成功率无关。口腔卫生状况、手术医生等几个因素影响成功率。结论:患者年龄、口腔卫生状况、操作者技术是影响微种植支抗成功的关键因素。
Objective: To study the influencing factors of success rate of maxillary buccal microinjection support. Methods: A total of 77 patients with micro-anchorage were implanted in Shenzhen Hospital of Peking University from January 2008 to December 2013. A total of 158 microinvasive screws were implanted. Statistical analysis of the factors influencing the success of implantations was performed. Results: There were 27 spikes out of 158, with a success rate of 83.1%. Eighteen of the 77 patients had implant splinters, with a success rate of 81.7%. The gender of the patient, the mode of tooth movement, the material of the implant, diameter, length and success rate were not related. Oral hygiene, surgeons and several other factors affect the success rate. Conclusions: Patient age, oral hygiene status, and operator skills are key factors that influence the success of micro-implantations.
