目的探讨在口腔正畸治疗中使用微型种植体的效果,并对其疗效进行系统评价。方法鹤岗矿业集团公司总医院于2014年3月-2015年6月期间正畸科收治的22例因牙列不齐及牙弓前突需要矫治的患者,对其临床资料进行分析,并随机分为观察组和对照组各11例,观察组患者采用微型种植体支抗,对照组采用Nance弓支抗,并对其疗效进行评价。结果观察组11例患者中无种植体失败,有2例患者出现种植体周围红肿现象,口服消炎药后症状消失。观察组患者间隙关闭时间、前突内收时间、上牙或下牙完全压低时间均优于对照组,差异具有统计学意义(P<0.01)。结论微型种植体支抗具有安全、有效、舒适、美观的效果,是一种突破性的技术,值得在临床上推广应用。
Objective To investigate the effect of using mini implants in oral orthodontic treatment and to evaluate its efficacy. Methods Totally 22 patients with orthognathic department who were treated by Hegang Mining Group General Hospital from March 2014 to June 2015 due to malformation of the dentition and protrusion of the dental arch had analyzed their clinical data and randomized Divided into the observation group and the control group of 11 cases, the observation group patients with micro-implant support, the control group with Nance bow support, and its efficacy evaluation. Results In the observation group, there was no implant failure in 11 patients. There were two cases of erythema around the implant. The symptoms disappeared after oral administration of anti-inflammatory drugs. The patients in the observation group had significantly shorter gap closure time, protrusion of the protrusion, and complete depression of the upper teeth or lower teeth than the control group. The difference was statistically significant (P <0.01). Conclusion Micro-implant anchorage is safe, effective, comfortable and beautiful. It is a breakthrough technique that is worth popularizing in clinic.
