目的:探讨微型种植体支抗在口腔正畸中的临床应用。方法:选取在我院接受口腔正畸的患者66例,分为观察组和对照组,两组患者均采用直丝弓矫治技术,拔除4颗第一前磨牙后观察组患者采取微型种植体支抗技术,对照组患者采取常规正畸支抗技术,对比两组患者治疗前后的头影测量数据,比较种植支抗与常规支抗的效果。结果:观察组患者磨牙前移量明显少于对照组,上中切牙唇倾角及凸距的减少量明显多于对照组,差异具有统计学意义(P<0.05)。结论:微型种植体支抗与常规支抗相比,支抗效果更好,且操作简便、损伤小、可即刻加力,应用于口腔正畸中的效果显著,值得在临床中推广。
Objective: To investigate the clinical application of mini-implant anchorage in orthodontics. Methods: Sixty-six patients with orthodontics in our hospital were divided into observation group and control group. The technique of straight wire arch was used in both groups. After removal of the four first premolar teeth, the patients in the observation group were treated with mini-implant Anti-technique, the control group of patients to take conventional orthodontic technique, compared two groups of patients before and after treatment of cephalometric data to compare the effect of implant support and conventional support. Results: The molars removal in the observation group was significantly less than that in the control group. The decrease of the lip inclination and the convex distance of the upper incision was significantly more than that of the control group, with statistical significance (P <0.05). CONCLUSION: Compared with conventional anchorage, the anchorage effect of micro implant is better, and its operation is simple, less damage and immediate force. It has obvious effect in orthodontics and is worth popularizing in clinic.
