本研究的目的是探索使用微型植入物进行骨骼固定，并评估其稳定性和失败原因。正畸治疗中使用了 45 个微型种植体。种植体的直径为2毫米，长度为8、10、12和14毫米。钻孔手术直接穿过皮质骨，无需任何切口或皮瓣手术。两周后，通过弹性链或镍钛螺旋弹簧施加 100-200 g 的力。使用卡方或费舍尔精确检验（如适用）对微型植入物失败的风险因素进行统计检查。微型种植体的平均植入时间约为 10-15 分钟。正畸力加载后，四个微型种植体松动。总体成功率为91.1%。种植体的位置是与失败相关的重要因素。总之，微型种植体易于插入骨骼固定，并且可以成功控制牙齿移动。
The aim of this study was to explore the use of mini-implants for skeletal anchorage, and to assess their stability and the causes of failure. Forty-five mini-implants were used in orthodontic treatment. The diameter of the implants was 2 mm, and their lengths were 8, 10, 12 and 14 mm. The drill procedure was directly through the cortical bone without any incision or flap operation. Two weeks later, a force of 100-200 g was applied by an elastometric chain or NiTi coil spring. Risk factors for the failure of mini-implants were examined statistically using the Chi-square or Fisher exact test as applicable. The average placement time of a mini-implant was about 10-15 min. Four mini-implants loosened after orthodontic force loading. The overall success rate was 91.1%. The location of the implant was the significant factor related to failure. In conclusion, the mini-implants are easy to insert for skeletal anchorage and could be successful in the control of tooth movement.
