Abstract:

Objective    To analyze the clinical efficacy of 2D lingual brackets self-ligating technique in the treatment of malocclusion of adult patients. Methods    The clinical data of 30 adult patients with malocclusion treated in our hospital between December 2014 and December 2015 were reviewed. The plaster dental model， profile and oral photograph，and the satisfaction rate of patients in this group were observed，and the cephalometric parameters of the patients before and after the treatment were compared. Results    The total effective rate of plaster dental model，profile and oral photograph in this group of patients after the treatment was up to 83.33%，and the satisfaction rate amounted to 96.67%. The changes of cephalometric parameters before and after treatment in Angle classⅠpatients showed no significant difference（P＞0.05）. Conclusion    The treatment with 2D lingual self-locking appliance technology for adult skeletalⅠmalocclusion（bite）anomalies has good effect，and for skeletal ClassⅠ non-extraction cases it has clinical value.

摘要：

目的    分析2D舌侧自锁矫治技术矫治成年骨性Ⅰ类错牙合畸形患者的临床有效性。方法    2014年5月至2015年5月山西省大同煤矿集团有限责任公司总医院口腔科诊治的30例成年错牙合畸形患者临床资料，观察对比患者矫治前后模型、面部牙合照片，并通过问卷形式调查患者矫治满意度。结果    根据患者矫治前后模型、面牙合照片对比判定，矫治总有效率为83.33%；问卷调查结果显示，患者满意度为96.67%；患者矫治前后X线头影测量指标未发生明显改变（P＞0.05）。结论    2D舌侧自锁矫治技术矫治成年骨性Ⅰ类错牙合畸形效果良好，对于骨性Ⅰ类非拔牙病例具有临床应用价值。
