目的利用Tip-Edge plus托槽的独特性探索差动力技术矫治安氏Ⅱ1类错的疗效观察。方法收集25例安氏Ⅱ1类错患者,均采用Tip-Edge plus技术进行矫治,检测矫正前后头颅侧位片硬组织和软组织观察指标,并进行比较分析。结果所有患者矫治效果显著,前牙覆覆盖均达到正常范围,两侧磨牙、尖牙关系变成中性关系,侧貌改善明显。矫治前后硬组织测量结果差异均有统计学意义(均<0.05),矫治前后软组织测量结果差异均有统计学意义(均<0.05)。结论 Tip-Edgeplus技术在矫治安氏Ⅱ1类错能快速有效地打开咬内收压低上下前牙,明显改善软组织侧貌,疗效显著,值得临床推广。
Objective To explore the curative effect of differential technique in treatment of Class Ⅱ 1 malocclusion by using the uniqueness of Tip-Edge plus brackets. Methods Twenty-five patients with Class Ⅱ 1 malocclusion were collected. The patients were treated with Tip-Edge plus technique. The indexes of hard tissue and soft tissue before and after correction were measured and compared. Results All patients had significant effect of orthodontic treatment. The coverage of both anterior and posterior teeth reached the normal range. The molars and canines on both sides became neutral and the lateral appearance improved obviously. Before and after the treatment of hard tissue measurements were statistically significant differences (all <0.05), before and after correction of soft tissue measurement results were statistically significant (all <0.05). Conclusion Tip-Edgeplus technology in the treatment of Class Ⅱ Division 1 malocclusion can rapidly and effectively open the lower bite occlusal lower anterior teeth, significantly improve the soft tissue profile, the effect is significant, worthy of clinical promotion.
