无托槽隐形矫治技术与固定矫治技术的临床疗效分析

CURATIVE EFFICACY OF NON- BRACKET ORTHODONTIC TECHNIQUE VERSUS FIXED ORTHODONTIC TECHNIQUE

目的 分析无托槽隐形矫治技术与固定矫治技术的临床疗效。方法 随机选自2012年8月～2014年8月本院收治的牙齿正畸患者86例,随机分为两组,各43例,对照组予固定矫治技术,研究组予无托槽隐形矫治技术,分析两组的临床效果。结果 研究组倾斜牙矫正、转位牙扭正与治疗完成时间均短于对照组,差异具有统计学意义（p〈0.05）。对照组除龈沟探诊深度无明显变化外,其他各项指数均明显增加（p〈0.05）。两组治疗前各项牙周指数无明显差异,治疗后研究组菌斑指数明显低于对照组（p〈0.05）,其他指数相比无明显差异。结论 相较于固定矫治技术,无托槽隐形矫治技术具有较高正畸效率,且其对患者牙周健康影响较小,值得临床推广应用。

Objective To analyze the clinical efficacy of non - bracket orthodontic technique versus fixed orthodontic technique. Methods 86 cases receiving orthodontics in our hospital from August 2012 to August 2014 were selected. They were randomly divided into two groups, each with 43 cases. The control group was treated with fixed orthodontic technique, whereas the study group was treated with non - bracket technique. The clinical curative effects of the two groups were analyzed. Results The time of correction of inclined teeth and transpositioned teeth and completed treatment time in the study group were shorter than those in the control group, with significant difference （p 〈 0.05 ）. The gingival sulcus and probing depth in the control group showed no obvious changes, but other indexes were significantly increased （p 〈0.05 ）. And each periodontal index showed no significant difference between the two groups before treatment. But after treatment, the plaque index of the study group was significantly lower than that in the control group （p 〈 0.05 ）. There were rio significant differences in the other indexes between the two groups. Conclusion Compared with fixed orthodontic technique, non - bracket orthodontic technique is of higher orthodontic efficiency and less harm to periodontum, so it is worthy of clinical application.
