无托槽隐形矫治法与固定矫治法对成人错牙合畸形的诊治效果

目的 对比采用无托槽隐形矫治器和固定矫治器对成人错牙合 畸形的诊治效果。 方法 选择2015年1月-2016年12月在杭州市萧山区第一人民医院就诊的122例成年首诊错牙合 畸形患者作为研究对象。男性34例,女性88例。平均年龄(28.0±4.5)岁。根据患者的意愿,54例采用固定矫治器(固定矫治器组),另外68例采用无托槽隐形矫治器(隐形矫治器组)治疗。观察指标:治疗完成时间(倾斜牙矫正、转位牙扭正),矫治效果及患者满意度。 结果 固定矫治器组倾斜牙矫正时间、转位牙扭正时间及治疗完成平均时间分别是(30.81±3.04)周、(27.46±4.22)周、(76.35±8.29)周,比隐形矫治器组的相应指标值都要长[分别是(15.96±3.03)周、(18.47±3.50)周、(42.55±3.68)周](均P<0.05),但固定矫治器组与隐形矫治器组的矫治效果ABO总评分[分别是(29.36±2.21)分、(29.98±2.60)分]比较,差异无统计学意义(t=1.423,P>0.05)。隐形矫治器组在咀嚼功能(8.47±1.26)、语言功能(9.13±1.34)、美观(8.24±1.45)、舒适(9.35±0.48)的满意度评分(分),均较固定矫治器组[分别是咀嚼功能(6.79±1.05)分、语言功能(7.45±1.30)分、美观(6.08±1.47)分、舒适(6.96±0.88)分]更高(均P<0.05)。 结论 无托槽隐形矫治器与固定矫治器均可获得较为满意的矫治效果,但前者治疗所需时间更短、患者满意度更高。 

Comparison of the effect of invisible braces and conventional braces in treatment of adult malocclusion

Objective To compare the curative effect of invisible braces and conventional fixed appliances in the treatment of malocclusion in adults. Methods From January, 2015 to December, 2016, 122 adults with malocclusion diagnosed in our department were selected as the subjects. There were 34 males and 88 females. The average age was (28.0±4.5) years. According to the wishes of the patients, 54 cases were treated with fixed appliances (fixed appliances group), and the other 68 cases were treated with invisible orthodontic appliances (invisible orthodontic appliance group). The observation indicators included treatment completion time (tilt teeth correction, transposition teeth torsion), treatment effect and patient satisfaction. Results The correction time (week), orthodontic time (week) and the average time of treatment (week) in the fixed appliances group were 30.81±3.04), (27.46±4.22) and (76.35±8.29), respectively, which were longer than those of the invisible orthodontic appliance group[(15.96±3.03), (18.47±3.50) and (42.55±3.68)], respectively, P<0.05. In the fixed appliances group and invisible orthodontic appliance group, the total score of the correction effect (scores) were (29.36±2.21) and (29.98±2.60), respectively, the difference was not statistically significant (t=1.423, P>0.05). In the invisible orthodontic appliance group, the chewing function (8.47±1.26), language function (9.13±1.34), beauty (8.24±1.45), and comfort (9.35±0.48) were higher than those of the fixed appliances group[chewable function (6.79±1.05), language function (7.45±1.30), beauty (6.08±1.47), and comfort (9.35±0.48)respectively (all P<0.05)]. Conclusion Both invisible orthodontic appliances and conventional fixed appliances can obtain satisfactory curative effect, but the treatment time of invisible orthodontic appliance is shorter and the patient's satisfaction is higher.
