摘要

目的:当一个或多个上门牙咬合舌下门牙时,出现前交叉牙合。采用几种技术矫正前牙合。本文的目的是介绍使用多环弓丝治疗I类关系下的前牙合。方法:一名24岁女性,主诉前牙合。她的牙齿轮廓凹,除上颌犬齿外所有牙齿都存在,4毫米的反向覆盖,4毫米的下前牙拥挤,25%的覆盖。治疗从下牙弓开始,拔除下第一前磨牙。采用不同顺序的镍钛合金和不同顺序的不锈钢弧线。结果:18个月矫正成功。完成了正常的上喷、上咬合和正颌剖面。结论:采用后缩多环弓治疗前牙合,可达到正常的上牙合和上牙合。

Treatment of anterior dental crossbite in adult Libyan patient
Objective: Anterior crossbite presents when one or more of the upper incisors occlude lingual to lower incisors. Several techniques were used to correct anterior crossbite. The aim of this article was to present the treatment of anterior crossbite under skeletal Class I relationship using multilooped archwire. Methods: A 24-year-old female has a complaint of anterior crossbite. She has concave profile, all her teeth present except the maxillary canines, 4 mm reverse overjet, 4 mm crowding in the lower anterior and 25% overbite. The treatment was started in the lower arch by the extraction of the lower first premolars. Different arch sequences of nickel–titanium alloys, followed by different sequences of stainless steel archwires were used. Results: The correction of crossbite was achieved successfully within 18 months. Normal overjet and overbite and orthognathic profile were accomplished. Conclusion: The treatment of anterior crossbite was achieved using retraction multilooping arch to achieve normal overjet and overbite.
