OBJECTIVE
To describe an orthodontic treatment that combines an esthetic approach (clear aligners) with surgery (alveolar corticotomy).
MATERIALS AND METHODS
A patient with moderate dental crowding and Class I skeletal and molar relationships was selected. Orthodontic records of the patient were taken. Periodontal indexes, oral health-related quality of life (OHRQoL), and treatment time were evaluated. After we reflected a full-thickness flap beyond the teeth apices, the cortical bone was exposed on the buccal aspect and a modified corticotomy procedure was performed. Interproximal corticotomy cuts were extended through the entire thickness of the cortical layer, just barely penetrating into medullary bone. Orthodontic force was applied on the teeth immediately after surgery.
RESULTS
Total treatment time was 2 months. Periodontal indexes were improved after correction of crowding. A deterioration of OHRQoL was limited to 3 days following surgery.
CONCLUSION
This case report may encourage the use, limited to selected cases, of corticotomy associated with clear aligners to treat moderate crowding.
目的
描述一种将美学方法（透明矫治器）与手术（牙槽骨皮质切开术）相结合的正畸治疗方法。
材料与方法
选取一名患有中度牙列拥挤且骨骼和磨牙关系为I类的患者。采集该患者的正畸记录。评估牙周指数、口腔健康相关生活质量（OHRQoL）和治疗时间。在将全厚瓣翻至根尖以外后，暴露颊侧皮质骨并进行改良的皮质切开术。邻间皮质切开切口贯穿皮质层全层，仅轻微穿透至髓质骨。术后立即对牙齿施加正畸力。
结果
总治疗时间为2个月。牙列拥挤矫正后牙周指数得到改善。OHRQoL的恶化仅限于术后3天。
结论
本病例报告可能会鼓励在特定病例中使用与透明矫治器相关的皮质切开术来治疗中度牙列拥挤。
