摘要: 替牙期是儿童牙合颌面生长发育变化最活跃的时期之一,是唇腭裂患者许多错牙合问题出现并加重的阶段,也是唇腭裂序列治疗中重要的治疗阶段。唇腭裂患者由于先天畸形、手术创伤及瘢痕等因素影响,常造成上颌骨的发育不足,从而引起颌间横向及矢状向关系的异常,表现为前、后牙的反牙合;先天缺牙及因牙齿发育不良和口腔卫生维护不佳所致的牙齿早失,常使唇腭裂患者的错牙合畸形更加复杂。对唇腭裂患者替牙期存在的颌间横向及矢状向关系异常的矫治和常见的牙齿异常的治疗,可以减轻患者牙合颌面畸形,改善口颌系统功能,为牙合颌面继续正常发育创造条件。替牙期所进行的牙槽突裂植骨是唇腭裂序列治疗中的关键治疗,为患者后续错牙合畸形的正畸治疗打下良好的基础,而植骨前必要的正畸有望提高植骨的疗效。本文将针对唇腭裂患者替牙期常见的错牙合畸形及其矫治进行阐述。

Abstract: The mixed dentition period is one of the most active periods of occlusal and maxillofacial growth and development. It is the period when the problems of malocclusion appear and aggravate in patients with cleft lip and palate, and an important treatment stage in the sequential treatment of cleft lip and palate. Due to congenital malformation, surgical trauma and scarring, patients with cleft lip and palate often suffer from maxillary underdevelopment, which causes abnormal intermaxillary transverse and sagittal relationships, manifesting as anterior and posterior crossbite. Congenital missing teeth and early tooth loss due to poor tooth development and poor oral hygiene further complicate the malocclusion in patients with cleft lip and palate. During the mixed dentition period, orthodontic treatment of abnormal intermaxillary transverse and sagittal relationship and the treatment of the tooth abnormalities in patients with cleft lip and palate can alleviate occlusal and maxillofacial deformities, improve the function of the stomatognathic system, and be beneficial to the occlusal and maxillofacial development. The alveolar bone grafting during the mixed dentition period is vital in the sequential treatment of cleft lip and palate, which lays a good foundation for the subsequent orthodontic treatment of malocclusion. The necessary orthodontic treatment before bone grafting is expected to improve the treatment effect of bone grafting. In this article, we will address the common malocclusion and the corresponding orthodontic treatment in patients with cleft lip and palate during the mixed dentition period.
