摘要: 目的: 探究颧牙槽嵴下微种植体对骨性Ⅱ类错牙合畸形患者微笑美学效果的影响。方法: 选择2017年1月~2021年1月我院收治的103例骨性Ⅱ类错牙合畸形患者,按照随机数字表法分为研究组(n=52,颧牙槽嵴下微种植体+直丝弓矫治)和对照组(n=51,头帽口外弓+直丝弓矫治),比较两组总体疗效、矫治时间、治疗后6个月头影测量指标、微笑美学效果及并发症情况。结果: 两组矫治成功率比较并无差异(P>0.05),而研究组矫治时间[(14.3±3.6)月]低于对照组[(20.1±4.2)月,P<0.05];两组矫治后切牙唇倾度(U1-L1,L1-MP,U1-SN)、ANB、上颌中切牙内收量(U1-Ptm)、上颌磨牙远中移动量(U6-SP)、覆盖(OJ)、覆颌(OB)均明显改善,且研究组矫治前后U6-SP变化量低于对照组,U1-L1、U1-SN、U1-Ptm、L1-MP变化量高于对照组(P<0.05);两组发生牙根吸收、上颌窦底感染、创伤性溃疡、种植体周围炎等并发症比较无明显差异(P>0.05)。结论: 颧牙槽嵴下微种植体矫治骨性Ⅱ类错牙合能缩短矫治时间,前牙内收效果更佳,微笑美观明显提高,值得临床推广。

Abstract: Objective: To explore the smile aesthetic outcomes of infrazygomatic crest miniscrews in patients with skeletal Class Ⅱ malocclusions. Methods: One hundred and three patients with skeletal Class Ⅱ malocclusions admitted to our hospital from January 2017 to January 2021 were selected and assigned into two groups according to the orthodontic treatment plans. Study group (n=52) received infrazygomatic crest miniscrews plus straight-wire appliance, while control group (n=51) was given facebow headgear plus straight-wire appliance. The overall therapeutic efficacy, treatment duration, cephalometric indices six months post-treatment, smile aesthetic effects, and complication rates were compared between the two groups. Results: There was no difference in the success rate of treatment between the two groups (P>0.05),and the treatment time of the study group (14.3±3.6) was lower than that of the control group (20.1±4.2) (P<0.05). There was a notable improvement in the angle formed between the long axis of upper central incisor and the lower central incisor (U1-L1), angle formed between the long axis of lower central incisor and the mandibular plane (L1-MP), angle between the long axis of the upper central incisor and the plane of the anterior skull base (U1-SN), point A-Nasion-point B (ANB) angle, maxillary central incisor adduction (U1-Ptm), maxillary molar distal movement (U6-SP), overjet (OJ), and overbite (OB) in both group after treatment. The amount of change in U6-SP was smaller and the amount of change in U1-L1, U1-SN, U1-Ptm and L1-MP was larger in study group than that in control group before and after orthodontic treatment (P<0.05). There was no statistical difference between two groups in the comparison of the complications such as root resorption, maxillary sinus floor infection, traumatic ulceration, and peri-implantitis (P>0.05). Conclusion: Application of infrazygomatic crest miniscrews in patients with skeletal Class Ⅱ malocclusions can effectively shorten the orthodontic time, improve the maxillary retraction of anterior teeth, and ameliorate the smile aesthetics.
