目的针对乳前牙反,对比“复合树脂唇切面斜导板法”与“上颌垫式矫治器”的疗效及复发率。方法选择乳前牙反患儿46例,实验组23例用“复合树脂唇切面斜导板”矫治,对照组23例用“上颌牙合垫式矫治器”进行矫治,分析了两个组不同时间点达到矫治人数的构成比,和两组的复发率。结果实验组和对照组的复发率差异无统计学意义(P>0.05),实验组和对照组的不同时间点达到矫治人数的构成比差异无统计学意义(P>0.05)。结论复合树脂唇切面斜导板法在乳前牙反矫治上疗效肯定,并且操作简便,费用低廉,适合基层医院推广应用。
Objective To evaluate the efficacy and recurrence rate of the anterior tibialis anterior crossbite and the “composite resin lip incline oblique guide plate method” and the “maxillary pad orthotic appliance”. Methods A total of 46 cases of anterior tinea capitis were selected, and 23 cases in the experimental group were treated with “composite resin lip incline guide plate ”. The control group was treated with “maxillary occlusal pad appliance” and analyzed The two groups at different time points to reach the composition ratio of the number of patients, and the recurrence rate of the two groups. Results There was no significant difference in relapse rate between the experimental group and the control group (P> 0.05). There was no significant difference between the experimental group and the control group (P> 0.05). Conclusions The composite resin lip incision diagonal plate method is effective in the treatment of anterior crossbite of the anterior teeth and is easy to operate with low cost and suitable for the popularization and application of primary hospitals.
