微型种植钉支抗在口腔正畸中的临床应用效果

Clinical Application Effect of Micro-Planting Nail Support Anti-Orthodontics

目的探讨口腔正畸患者接受微型种植钉支抗的治疗效果,为该病症治疗提供理论依据。方法选择2016年4月—2017年8月在该院接受口腔正畸治疗的70例患者,随机分为对照组30例与观察组40例,对照组应用口外弓强支抗治疗,观察组患者接受口外弓强支抗治疗,对比两组病例临床治疗效果与不良反应发生情况。结果观察组临床治疗有效率为95.0%,高于对照组73.3%,组间差异有统计学意义(χ~2=6.572,P<0.05);观察组不良反应发生率为7.5%,低于对照组36.7%,组间差异有统计学意义(χ~2=5.120,P<0.01);观察组上中切牙唇倾角、凸距减少量和磨牙位移分别为(0.73±0.64)mm、(29.68±6.90)°、(4.63±0.85)°,对照组上述指标检测结果分别为(3.74±0.65)mm、(12.35±4.50)°、(2.56±0.64)°,组间数据差异有统计学意义(t=11.547、14.021、10.245,P<0.05)。结论采用微型种植钉支抗矫正口腔畸形,操作灵活,稳定性优良,疗效显著,不良反应发生率低,值得进一步推广。

Objective To investigate the therapeutic effect of micro-planting nail anchorage in orthodontic patients, and to provide theoretical basis for the treatment of this disease. Methods Seventy patients who underwent orthodontic treat- ment in the hospital fi＇om April 2016 to August 2017 were randomly divided into the control group of 30 patients and the observation group of 40 patients. The control group received extraoral arch strong anchorage therapy. The patient received an extra-oral bow strong-resistance treatment, and the clinical treatment effect and adverse reactions occurred in the two groups. Results The effective rate of clinical treatment was 95.0% in the observation group, which was high- er than 73.3% in the control group. The difference between the two groups was statistically significant （χ2=6.572, P〈 0.05）. The incidence of adverse reactions in the observation group was 7.5%, lower than that in the control group of 36.7%, the difference between the groups was statistically significant （χ2=5.120, P〈0.01）; in the observation group, the upper incisor lip inclination, the reduction of the convex distance and the molar displacement were （0.73.±0.64） mm, re- spectively （29.68 ±6.90）°, （4.63±0.85）°, the results of the above indicators in the control group were （3.74±0.65） mm, （12.35±4.50）°, （2.56±0.64）°, and the differences between the groups were statistically significant （t=11.547, 14.021, 10.245, P〈0.05）. Conclusion The use of micro-planting nails to correct oral deformities, flexible operation, excellent stability, significant curative effect, low incidence of adverse reactions, it is worth further promotion.
