直丝弓技术结合平面导板矫治前牙深覆牙合的效果分析

Effects of straight arch wire technique combined with flat bite plate correction on front teeth deep overbite

目的:了解直丝弓技术结合平面导板矫治前牙深覆牙合的临床效果。方法:对我院2012年3月-2014年3月收治的前牙深覆牙合患者进行抽样,选取76例患者随机分成两组。对照组单纯应用直丝弓固定矫治器打开咬合,实验组应用直丝弓技术结合平面导板进行矫治,观察两组临床治疗效果。结果:实验组总有效率(94.74%)明显优于对照组(65.79%),且咬合完全打开平均时间(3.42±1.21)个月明显低于对照组(5.62±1.51)个月,差异有统计学意义(P<0.05)。结论:直丝弓技术结合平面导板矫治前牙深覆牙合临床疗效确切,安全指数高,值得临床积极推广与应用。

Objective To study the clinical effect of straight arch wire technique combined with flat bite plate correction on front teeth deep overbite. Methods Selecting 76 patients with front teeth deep overbite in the hospital from March,2012 to March,2014,and randomly dividing them into two groups. The control group only received straight arch wire fixed correction machine to open bite, and the experimental group received straight arch wire technique combined with flat bite plate correction.The clinical effect of the two groups was compared. Results The total effective rate of the experimental group（94.74%）was superior to the control group（65.79%）,and the average time of complete bite open in the experimental group,which was（3.42±1.21）months,was significantly lower than the control group, which was（5.62 ± 1.51）months,with significantly statistical meaning（P〈0.05）. Conclusion There is exact clinical effect of straight arch wire technique combined with flat bite plate correction on front teeth deep overbite,with high safety index.So it is worth clinical promotion and application.
