THIS PAPER ILLUSTRATES THE COMBINED NONEXTRACTION ORTHODONTIC TREATMENT WITH THE CORTICOTOMY TECHNIQUE IN AN ADULT PATIENT (AGE: 25 years and 3 months) with severely crowded arches to accelerate tooth movement and shorten the treatment time. Both her upper lateral incisors were congenitally absent and both upper central incisors' roots were short. Initial fixed orthodontic appliances (bidimensional) were bonded and one week later buccal and lingual corticotomy with alveolar augmentation procedure in the maxilla and mandible was performed. Orthodontic activation to level and align and unravel the crowding was performed every two weeks. The total treatment time was 8 months with no adverse effects observed at the end of active treatment. The addition of the decortication procedure to the conventional orthodontic therapy decreased the duration of treatment significantly. Successful alignment of both arches with ideal overbite and overjet as well as adequate occlusion was achieved.
本文阐述了在一名成年患者(年龄:25岁3个月)中,联合应用皮质切开术进行非拔牙正畸治疗,该患者牙弓严重拥挤,目的是加速牙齿移动并缩短治疗时间。她的上颌双侧侧切牙先天缺失,上颌双侧中切牙牙根短。最初粘结了固定正畸矫治器(二维的),一周后在上颌和下颌进行了颊侧和舌侧皮质切开术及牙槽嵴增高术。每两周进行一次正畸加力以排齐整平并解除拥挤。总治疗时间为8个月,在积极治疗结束时未观察到不良反应。在传统正畸治疗中增加去皮质术显著缩短了治疗时间。成功排齐了两个牙弓,达到了理想的覆合覆盖以及良好的咬合关系。
