目的观察青少年口腔正畸临床治疗效果。方法选取医院2014年1月-2015年12月收治的口腔正畸青少年100例,按照随机数字表法分为观察组和对照组各50例,观察组患者给予微型种植体支抗正畸治疗,对照组给予常规正畸方法,观察2组临床疗效;对2组患者磨牙移位、上中切牙倾角差及上中切牙凸距差进行记录;详细统计2组患者不良反应发生情况,如口腔炎症、不适感及组织轻度水肿等。结果观察组患者治疗总有效率为96.0%显著高于对照组的74.0%,差异有统计学意义(P<0.05);磨牙移位距离短于对照组,上中切牙倾角差、上中切牙凸距差高于对照组,差异均有统计学意义(P<0.05);观察组患者的不良反应发生率为8.0%低于对照组的30.0%,差异有统计学意义(χ~2=15.7245,P=0.0000)。结论在青少年口腔正畸中,微型种植体支抗正畸有利于提高治疗有效率,不良反应少,安全性更高,具有重要的应用价值。
Objective To observe the effect of clinical treatment of adolescent orthodontics. Methods 100 orthodontic adolescents admitted from January 2014 to December 2015 in our hospital were divided into observation group (50 cases) and control group (50 cases) according to the random number table. The patients in the observation group were given orthodontic treatment with micro-implant, The control group was given conventional orthodontic method to observe the clinical curative effect of the two groups. The molars displacement, the incisive incisors of the upper and middle incisors and the convex distance of the upper incisors were recorded. The incidence of adverse reactions in the two groups were statistically analyzed, Oral inflammation, discomfort and mild edema and so on. Results The total effective rate of observation group was 96.0%, which was significantly higher than that of control group (74.0%), the difference was statistically significant (P <0.05); the distance of molars shift was shorter than that of control group (P <0.05). The incidence of adverse reactions in the observation group was 8.0% lower than that in the control group (30.0%), the difference was statistically significant (χ ~ 2 = 15.7245, P = 0.0000). Conclusion In orthodontics of adolescents, micro-implant orthodontics is beneficial to improve the treatment efficiency, less adverse reactions, higher safety, and has important application value.
