Rapid canine distalization is a technique involving periodontal ligament distraction. The primary aim of this technique is to distalize the canines without anchorage loss and to shorten the duration of orthodontic treatment. After the rapid canine distalization, the healing process of the periodontal ligament is similar to rapid palatal expansion and requires a consolidation period. The long consolidation period of the technique conflicts with the second aim. Skeletal anchorage systems seem to compensate for this conflict because they can be also used for retraction of incisors during consolidation period. This case report presents the orthodontic treatment of a 16-year-old female, who had a bimaxillary retrusion and a dental Class II division I malocclusion. Upper first premolars were extracted and, while the canines were being distalized rapidly by periodontal ligament distraction, the incisors were retracted using a zygomatic anchorage system. The treatment of the patient was completed in five months without any anchorage loss.
快速犬齿远中移动是一种涉及牙周膜牵张的技术。该技术的主要目的是在不丧失支抗的情况下使犬齿远中移动，并缩短正畸治疗时间。快速犬齿远中移动后，牙周膜的愈合过程与快速腭扩展相似，需要一个巩固期。该技术较长的巩固期与第二个目的相冲突。骨支抗系统似乎可以弥补这一冲突，因为它们也可用于在巩固期内回收切牙。本病例报告展示了一名16岁女性的正畸治疗过程，该患者双颌后缩且为安氏II类1分类错牙合。拔除上颌第一前磨牙，在通过牙周膜牵张使犬齿快速远中移动的同时，使用颧骨支抗系统回收切牙。患者的治疗在五个月内完成，未出现任何支抗丧失。
