文题释义:

支抗:正畸矫治过程中,任何施于施治牙使其移动的力必然同时产生一个方向相反、大小相同的力,而支持这种移动矫正牙体引起的反作用力。实际上支抗是一个提供产生牙齿矫治力的基础。一般在正畸治疗中,支抗部分主要是由非矫治牙组成,腭部及牙槽也可作为支抗部分。支抗部分的牙齿受到矫治力所产生相反方向力即支抗力的作用。支抗分为颌内支抗、颌间支抗和颌外支抗3种。
微型种植体:一般植入上下颌骨牙根之间的牙槽骨上,通过种植体与需要移动的牙齿、牙弓加力,可以达到前牙内收过程中后牙几乎不前移,是传统方法无法比拟的。长度5-12 mm,直径1.3-2.3 mm的种植体支抗,具有体积小,植入方便,效果肯定,价格低,使用完取出方便,且不依赖患者合作程度的特点。

 

背景:传统的支抗方法具有舒适性差、不易控制、影响美观,依赖患者的密切配合等缺点,微型种植体支抗的临床研究和应用时间较短,目前关于微型种植体在口腔正畸治疗中的应用价值存在较大的争议。
目的:研究微型种植体支抗在口腔正畸治疗中的应用价值。
方法:选择2012年1月至2015年6月在雅安市人民医院眼耳鼻喉实验中心接受口腔正畸治疗的80例患者作为研究对象,按照随机数表法将患者分为试验组和对照组,各40例,试验组患者采用微型种植支抗技术,对照组采用口外弓加强支抗正畸法,两组患者均持续治疗2年。
结果与结论:试验组患者治疗成功率明显高于对照组(P < 0.05),患者上中切牙凸距差、上中切牙倾角、磨牙移位、上齿槽座角、尖牙间宽度等均明显优于对照组(P < 0.05)。治疗干预4,8周时,两组患者牙周组织骨保护素表达水平差异无显著性意义(P > 0.05)。但试验组患者的不良反应率明显低于对照组(P < 0.05)。说明微型种植体支抗能够明显提高口腔正畸治疗患者的治疗效果,提高治疗成功率,降低术后感染发生率,具有较好的安全性和稳定性,具有较好的临床应用价值。

Abstract:

BACKGROUND: Traditional orthodontic anchorage has the disadvantages of discomfort, difficult to control, affecting the appearance, and relying on patient’s close cooperation. Because of short-time clinical research and application, mini-implant anchorage has a great controversy in the orthodontic treatment.
OBJECTIVE: To explore the application value of mini-implant anchorage in the orthodontic treatment.
METHODS:Eighty cases undergoing the orthodontic treatment at the Center of Ophthalmology and Otolaryngology, Yaan People’s Hospital in China from January 2012 to June 2015 were enrolled in this study. These patients were equally randomized into test group and control group, which were subjected to mini-implant anchorage or headgear anchorage, respectively. The treatment was continued for 2 years in the two groups.
RESULTS AND CONCLUSION: After the treatment, the successful rate in the test group was significantly higher than that in the control group (P < 0.05); the upper central incisor convex distance difference, inclination angle of the upper central incisor, displacement of the molar, SNA angle, inter-canine width, were significantly better in the test group than the control group (P < 0.05). At weeks 4 and 8 after intervention, there was no difference in the expression of osteoprotegerin in the periodontal tissue between the two groups (P > 0.05), but the rate of adverse reactions was significantly lower in the test group than the control group (P < 0.05). These findings indicate the mini-implant anchorage method can significantly improve the therapeutic efficacy, improve the success rate of treatment, and reduce the incidence of postoperative infections, which has good safety and stability, and has good clinical application value.
