[Orthodontic treatment in multidisciplinary sequential treatment of patients with cleft lip and palate].

Cleft lip and palate is the most common congenital maxillofacial defect. The modern treatment of cleft lip and palate is a sequential treatment with multidisciplinary collaboration, which can restore the maxillofacial morphology and function, and rebuild the psychosocial adaptation of the patients. Orthodontic treatment is almost throughout whole process of the sequential treatment. Due to the professional attention to maxillofacial growth and development, orthodontists have become one of the most crucial members during the multidisciplinary treatment of cleft lip and palate. Orthodontists are required in the different stages of maxillofacial growth and development to provide suggestions and necessary treatment. By orthodontic treatment, it can not only solve the problem of malocclusion and promote the maxillofacial growth and development, but also create a favourable condition for other therapies of sequential treatment, such as cleft lip and palate repair, bone grafting, prosthodontics, and even mental health. In order to improve the therapeutic effect of comprehensive treatment and to alleviate the burden of patients, orthodontists should learn more about the treatment of cleft lip and palate. This article mainly introduced the craniofacial deformities of cleft lip and palate and the progress of orthodontic treatment in the multidisciplinary treatment of cleft patients.唇腭裂是颌面部常见先天畸形，现代治疗是多学科协作的序列治疗，使患者能在（牙合）颌面形态及功能恢复正常的同时保持良好的社会心理适应性。唇腭裂序列治疗中正畸治疗几乎贯穿始终，正畸医师对（牙合）颌面发育的专业性关注，使正畸医师成为唇腭裂多学科联合治疗中的关键成员。唇腭裂生长发育的不同阶段均需要正畸医师的参与以提供治疗建议及必要的治疗。正畸治疗除解决患者错（牙合）问题、促进（牙合）颌面正常生长发育外，还为序列治疗的其他治疗如唇腭裂手术、植骨、修复乃至患者心理健康创造条件。正畸医师也应更多地了解唇腭裂的相关治疗，以提高唇腭裂综合治疗效果并减轻患者治疗负担。本文主要介绍唇腭裂常见（牙合）颌面畸形和序列治疗中的正畸治疗及相关研究进展。.
