A definition of labial incompetence is given and emptrasis placed on the fact that this is a symptom of maxillodental dysmorphism (MDD) and not of nasal dyspermeability. Pathogenic features are discussed, the relevant clinical and paraclinical diagnostic features of MDD outlined, and the different alveolodental and/or bony (maxillary or mandibular) dysmorphias responsible for labial incompetence described. Principles of orthodontic and surgical treatment are centered on re-establishment of a correct articulation and therefore labial competence.
给出了唇功能不全的定义，并强调这是颌牙畸形（MDD）的一种症状，而非鼻通气障碍。讨论了致病特征，概述了MDD相关的临床和辅助临床诊断特征，并描述了导致唇功能不全的不同牙槽牙和/或骨（上颌或下颌）畸形。正畸和外科治疗的原则以重新建立正确的咬合关系从而恢复唇功能为核心。
