摘　　要：目的研究不同因素对颧牙槽嵴种植支抗稳定性的影响。方法选取2017年6月至2019年6月在江门市口腔医院就诊的50例使用颧牙槽嵴种植支抗的正畸患者,共植入100颗种植钉。根据患者性别、年龄、负载时间及种植钉尺寸回顾性分析颧牙槽嵴种植支抗的松动率。结果青少年组种植钉松动率为22.7%,成年组松动率为7.14%,两组比较,差异有统计学意义(P<0.05)。1.6 mm×11.0 mm组种植钉松动率为25.0%,2.0 mm×13.0 mm种植钉松动率为10.0%,两组比较,差异有统计学意义(P<0.05)。结论颧牙槽嵴种植支抗的稳定性与年龄、种植钉尺寸有关,与性别、负载时间无关。【Objective】To study the influence of different factors on the stability of infrazygomatic crest implant anchorage.【Methods】A total of 100 implant screws were implanted in 50 orthodontic patients.According to the patient’s sex,age,loading time and miniscrew size,the failure rate of implant anchorage was analyzed.【Results】The failure rate of miniscrew was 22.7%in adolescent patients and 7.14%in adult patients,and the difference was statistically significant(P<0.05).The failure rate of 1.6 mm×11 mm miniscrew was 25.0%,and that of 2.0 mm×13 mm was 10.0%(P<0.05).【Conclusion】The stability of infrazygomatic crest implant anchorage is related to age,miniscrew size,but not related to sex and loading time.
