摘要:

文题释义:
生理性支抗Spee氏弓矫治系统(Physiological Anchorage Spee’s Wire System,PASS):目前正畸治疗中,PASS矫治器是在传统方丝弓、直丝弓矫治器以及自锁托槽矫治器基础上改良而来,目前国内对于PASS矫治器各方面的性能研究还处于萌芽状态,对于PASS矫治器在青少年后牙垂直控制方向的控制研究还在起步阶段。

背景:目前国内对于PASS矫治器的性能研究尚处于起步阶段,关于PASS矫治器在青少年后牙垂直控制方向的量化研究报道较少。
目的:分析垂直方向支抗控制与PASS矫治技术中上颌前突患者颌平面角变化、颏部形态的关系。
方法:以2016年3月至2019年3月在邢台医学高等专科学校第二附属医院进行治疗的120例上颌前突患者为观察对象,均采用微种植支抗治疗,随机分为2组,每组60例。对照组患者采用PASS矫治器治疗;观察组患者在PASS矫治器治疗基础上采取双侧上颌第一磨牙之间的垂直支持矫治器治疗。采用口腔X射线侧位片进行影像学诊断,对比两组患者治疗效果以及颏部形态的差异。
结果与结论:①治疗后4周,观察组患者上中切牙与前颅底平面相交的内下角、下中切牙长轴与下颌平面的内上角、下颌平面角、两垂足距离、下唇凸点到审美平面的距离显著低于对照组(P < 0.05),上下中切牙长轴交角显著高于对照组(P < 0.05);②治疗后4周,观察组患者的根尖点颏厚度、颏前点颏厚度、颏凹陷、颏倾斜度、颏软组织厚度显著低于对照组(P < 0.05),颏高度、颏突度、颏曲度、颏软组织凹陷深度显著高于对照组(P < 0.05);③提示在错牙合畸形患者的治疗中,相比单独使用PASS矫治器,采取PASS矫治器联合微种植支抗以及垂直方向的控制措施,可有效改善患者的颏部形态,效果显著。

Abstract: BACKGROUND: At present, the research on the performance of Physiological Anchorage Spee's Wire System (PASS) appliance in China is still in its infancy. Quantitative analysis of the effect of vertical anchorage control using PASS appliance for teenagers is seldom reported.
OBJECTIVE: To analyze the relationship between the vertical anchorage control and the changes of jaw plane angle and chin shape in patients with maxillary protrusion treated by PASS appliance. 
METHODS: 120 patients with maxillary protrusion were treated in the Second Affiliated Hospital of Xingtai Medical College from March 2016 to March 2019. The patients undergoing micro-implant anchorage treatment were randomly divided into observation group and control group, with 60 patients in each group. PASS appliance was used in the control group, and vertical support appliance between the first molars of both sides was used in the observation group. Oral X-ray lateral radiographs were used for imaging diagnosis to compare the effect and the difference of the chin shape between the two groups. 
RESULTS AND CONCLUSION: (1) At 4 weeks after treatment, the inner lower angle between the upper central incisor and the anterior skull base plane, the inner upper angle between the long axis of the lower central incisor and the mandibular plane, the angle of the mandibular plane, the distance between the two feet, and the distance from the lower lip bump to the aesthetic plane were significantly lower in the observation group than those of the control group (P < 0.05). The angle of the long axis of the upper and lower central incisors was significantly higher in the observation group than that of the control group (P < 0.05). (2) At 4 weeks after treatment, the apical point chin thickness, anterior chin thickness, chin depression, chin inclination, and chin soft tissue thickness of the observation group were significantly lower than those of the control group (P < 0.05), and the chin height, chin protrusion, and chin curvature and the depth of the soft tissue depression of the chin were significantly higher than those of the control group (P < 0.05). (3) It is concluded that in the treatment of patients with malocclusion, compared with PASS appliance, micro-implant anchorage combined with vertical control measures can effectively improve the shape of the chin, and the effect is significant.
