PURPOSE
To investigate the immediate load stability of domestic micro-titanium screws for anchorage in orthodontics.
METHODS
Adult orthodontic patients needing the greatest anchorage were included in the study. Domestic micro-titanium screws were used to be orthodontic anchorage, immediate implantation and loading were conducted.
RESULTS
A total of 52 implants of domestic micro-titanium anchorage in 20 patients were used. Forty-seven implants were successful in 20 patients,5 failed. The total loading time was 3-8 months.
CONCLUSIONS
Domestic micro-titanium implant screws for anchorage can meet the needs of clinical orthodontics. However, immediate loading results in 10.4% failure rate, especially for the implant with a diameter of 1.2mmx7mm.

目的
研究国产微型钛钉在正畸治疗中支抗的即刻加载稳定性。
方法
选取需要最大支抗的成年正畸患者纳入研究。采用国产微型钛钉作为正畸支抗，进行即刻植入和加载。
结果
共对20例患者植入52枚国产微型钛钉支抗。20例患者中47枚植入成功，5枚失败。总加载时间为3 - 8个月。
结论
国产微型钛钉支抗可满足临床正畸需求。然而，即刻加载导致10.4%的失败率，尤其是直径为1.2mm×7mm的种植体。由上海市奉贤区科学技术发展基金资助（项目编号：090602）。
