摘　　要：目的探讨微螺钉种植体支抗在口腔正畸中的临床效果。方法按诊断标准选取2015年9月—2019年9月河南省人民医院收治的80例错颌畸形患者,随机分为研究组和对照组,每组各40例。两组患者首先进行牙周清洁,有龋洞者先行龋洞治疗,后再用直丝弓自锁金属托槽矫治。待上、下牙列排齐整平后更换不锈钢丝,然后研究组给予微螺钉种植体支抗治疗,对照组采用非种植体支抗即口外弓强支抗进行治疗,两组患者均在治疗开始和结束时拍摄头颅正位、侧位片,测量分析X线头影,对两组不同支抗的临床矫治效果进行比较。结果本组患者中23例在上颌植入,17例在上、下颌位置均植入种植体,研究组患者40例共植入了93枚。微螺钉种植体研究组治疗总有效率为97.5%,对照组的总有效率为85.0%,两组疗效差异有统计学意义(P<0.05);研究组并发症如牙根吸收的发生率为37.5%,与对照组(22.5%)相比差异无统计学意义(P>0.05)。结论在口腔正畸技术中作为一种新的医疗技术出现的微螺钉种植体支抗,可以最大限度地改善患者的口腔功能及颜面美观状况,尽管微螺钉种植体支抗在临床正畸治疗中虽然也会发生牙根吸收情况,但整体疗效明显优于非种植体支抗,所以值得在临床上广泛使用。Objective To investigate the clinical effects of micro-screw implant anchorage in treatment of orthodontics.Methods Totally 80 patients with malocclusion admitted to our hospital from September 2015 to September 2019 were selected according to diagnostic criteria and randomly divided into study group and control group, 40 patients in each group. Patients in the two groups received periodontal cleaning first, caries were treated first, and then fixed with straight wire arch self-locking metal bracket. For upper and lower teeth row of neat after replacement of stainless steel wire, then the team implants micro screw was given by implants then control group, outmouth bow strong resistance to treatment, two groups of patients were taken in the treatment of the start and end head is, side slice, measurement analysis X thrum, on two groups of different resistance to compare the clinical treatment effect.Results In this study, 23 patients were implanted in the upper jaw, 17 were implanted in the upper and lower jaw, and a total of 93 implants were implanted in 40 patients in the study group. total effective rate was 97.5%;In the control group, total effective rate was 85.0%;The difference was statistically significant(P<0.01).In study group,the incidence of complications such as root resorption was 37.5% higher than that of the 22.5% in the control study(P<0.05).Conclusion Micro-screw implant anchorage in orthodontics in a significant effect,but either have a certain rate of occurrence of root resorption,its effect was significantly better than non-orthodontic implant anchorage,worthy of clinical use.
