Currently, more emphasis is being placed on non-extraction orthodontic treatment, thereby increasing the possibility of mild dental bimaxillary protrusion post-treatment. This adds to the potential for the return of mild anterior dental irregularity post-retention. For this patient, a comprehensive treatment plan including modification of facial growth has proved that a non-extraction approach for the correction of upper anterior crowding can produce good results without necessarily compromising long term stability.
目前,非拔牙正畸治疗受到更多重视,从而增加了治疗后出现轻度双颌牙前突的可能性。这也增加了保持后轻度前牙不齐复发的可能性。对于该患者,一个包括调整面部生长的综合治疗方案已证明,采用非拔牙方法矫治上前牙拥挤可以取得良好效果,且不一定会影响长期稳定性。
