This paper presents an orthodontic case of a large (14.5 mm) maxillary midline diastema that was related to the presence, and subsequent removal of 2 median maxillary supernumerary teeth and resulting bone loss. A combined orthodontic and maxillofacial approach involving bone grafting and fixed appliances was used to close the space. This episode of care was organized as interceptive treatment during development of the permanent dentition.
本文介绍了一例正畸病例，患者上颌中线出现较大间隙（14.5毫米），这与两颗上颌正中多生牙的存在及随后拔除多生牙导致的骨质流失有关。采用正畸与颌面联合治疗方法，包括植骨和固定矫治器来关闭间隙。此次治疗安排在恒牙列发育期间进行的阻断性治疗。
