无托槽隐形矫治技术用于牙齿正畸治疗中的临床效果观察

Clinical effects of invisible orthodontic brackets in orthodontic treatment

目的:探讨无托槽隐形矫治技术用于牙齿正畸治疗中的临床效果。方法:按随机数字表法将2016年2月至2018年3月在我院行牙齿正畸治疗90例患者分为两组,对照组45例患者给予传统固定矫治术治疗,观察组45例患者给予无托槽隐形矫治技术治疗。对比两组患者的疗效(转位牙扭正、倾斜牙矫正、治疗完成时间)以及治疗3个月后牙周健康指标,包括龈沟探诊深度(Sulcus probing depth,SPD)、龈沟出血指数(Sulcus bleeding index,SBI)、菌斑指数(Plaque index,PLI)、牙龈指数(Gingival index,GI)。结果:与对照组相比,观察组转位牙扭正、倾斜牙矫正、治疗完成时间均显著短于对照组(P<0.05);与对照组相比,观察组治疗后SPD、SBI、PLI较高(P<0.05),对照组与观察组治疗后GI对比,差异无统计学意义(P>0.05)。结论:无托槽隐形矫治技术用于牙齿正畸治疗中对牙周健康影响较小,可有效提高临床疗效。

Objective:To explore the clinical effects of invisible orthodontic brackets in orthodontic treatment.Methods:All together 90 cases of orthodontic treatment in our hospital from February 2016 to March 2018 were divided into two groups according to a random number table with 45 cases in each group.Patients in the control group were treated with traditional fixed orthodontic treatment.And patients in the observation group were treated with invisible orthodontic brackets.The efficacy and periodontal health index of the two groups was compared.Results:The observation group had shorter time for orthodontic treatment,inclined tooth correction and treatment(P<0.05)than the control group.The observation group had significantly higher SPD,SBI,PLI after treatment than the control group.Conclusion:Invisible orthodontic treatment without bracket has little effects on periodontal health and can effectively improve the clinical effects.
