摘　　要：目的探讨数字化隐形矫治系统与传统的功能矫治器前导下颌的疗效对比分析。方法收集2019年10月至2021年1月绍兴市口腔医院收治的下颌后缩儿童72例进行回顾性分析,采用随机数字表法分为隐形矫治组(Inv组)和传统功能矫治(Fun组),每组各36例。Inv组采用时代天使A6矫治系统,Fun组采用双颌垫(Twin-block)功能矫治器,两组患者均要求每天佩戴20h以上。佩戴10个月后,两组患者拍摄头颅侧位片及口内照片。通过模型测量磨牙关系和覆盖变化及头影测量分析等对比两组患者的临床疗效及美观程度,比较治疗满意度。结果治疗后两组治愈率比较,差异无统计学意义(P>0.05);患者停戴半年后比较两组治愈率,差异无统计学意义(P>0.05)。治疗前后头侧片分析表明,反映下颌位置的颅底-下齿槽座角(sella nasion B point angle,SNB)度数在Inv组和Fun组均变化显著,且Fun组的变化显著高于Inv组,差异有统计学意义(P<0.05)。上下齿槽座角(ANB angle,ANB)变化与SNB变化趋势一致,差异有统计学意义(P<0.05)。Inv组下前牙唇倾度变化高于Fun组,差异有统计学意义(P<0.05)。调查问卷结果显示,Inv组的舒适性和依从性远高于Fun组,差异有统计学意义(P<0.05)。结论时代天使A6矫治系统与Twin-block矫治器均能导下颌向前治疗下颌后缩畸形,Twin-block矫治器骨性效果显著大于A6系统,但A6系统佩戴舒适,患者依从性好,故其治愈率优于传统的功能矫治。Objective To investigate the comparative analysis of the efficacy of digital invisible orthodontic system and traditional functional orthodontic appliances for anterior mandibular guidance.Methods A total of 72 cases of children with receding mandibles admitted to Shaoxing Dental Hospital from October 2019 to January 2021 were collected for retrospective analysis and divided into the invisible orthodontic group(Inv group)and traditional functional orthodontic treatment(Fun group)according to the random number table method,with 36 cases in each group.The Inv group used the Times Angel A6 orthodontic system and the Fun group used the Twin-block functional orthodontic appliance with double jaw pads(Twin-block),and patients in both groups were required to wear the appliance for more than 20 hours a day.After 10 months of wear,lateral cephalograms and intraoral photographs were taken in both groups.The clinical outcomes and aesthetics of the two groups were compared by model measurements of molar relationships and changes in coverage and cephalometric analysis,and compared the satisfaction with the two orthodontic appliances.Results There was no statistically significant difference in the cure rate between the two groups after treatment(P>0.05);the difference was not statistically significant when comparing the cure rate between the two groups six months after patients stopped wearing them(P>0.05).Analysis of the lateral cephalometric films before and after treatment showed that the sella nasion B point angle(SNB),which reflects the position of the lower jaw,changed significantly in both the Inv and Fun groups,and the change in the Fun group was significantly higher than that in the Inv group,with a statistically significant difference(P<0.05).The change in ANB angle(ANB)was consistent with the change in SNB,and the difference was statistically significant(P<0.05).The change in the labial inclination of the lower anterior teeth in the Inv group was higher than that in the Fun group and the difference was statistically
