生长发育期唇腭裂患者的序列正畸治疗

Sequential orthodontic treatment for cleft lip and palate in the period of growth and development

唇腭裂是口腔颜面部最常见的先天性发育畸形,这类患者常伴随严重的错牙合畸形。正畸治疗是唇腭裂序列治疗的重要组成部分,贯穿于唇腭裂患者生长发育期的各个阶段。婴儿期鼻齿槽塑形术可重塑鼻、齿槽形态,为手术创造条件;替牙期是唇腭裂正畸治疗的关键时期,通过适时的植骨术前正畸治疗、扩弓和前方牵引等治疗,可以为尖牙的萌出创造条件,有效改善咬合及美观。

Cleft lip and palate is the most common cranio-facial birth defect, which is often accompanied by serious mal- occlusion. As an important part of the treatment for cleft lip and palate, sequential orthodontic treatment is applied in all stages of growth and development. Presurgical nasoalveolar molding can improve the nasoalveolar profile of the cleft lip and palate in infancy to prepare for the future operation. Denti- tion is the critical orthodontic period to treat cleft lip and pal- ate, which can facilitate the eruption of canines and effective- ly improve the occlusion and appearance through the orthodon- tic treatment before alveolus bone grafting, arch expansion and maxillary protraction in this period.
