Supernumerary teeth in the maxillary midline are common and can present both esthetic and pathologic problems that can be extremely difficult to solve. Early detection of the mesiodens is most important if such complications are to be avoided. This case required both surgical and orthodontic treatment to bring an unerupted, impacted maxillary central incisor into position. Using a combination of conservative surgical treatment and careful orthodontic management, the tooth was brought into good position in the dental arch and injury to root structure and surrounding oral tissues was avoided.
上颌中线多生牙很常见，会引发美观和病理问题，而这些问题极难解决。若要避免此类并发症，早期发现正中牙至关重要。该病例需要手术和正畸治疗，以使一颗未萌出、阻生的上颌中切牙归位。通过保守手术治疗与精心正畸管理相结合的方法，这颗牙齿在牙弓中归位良好，且避免了牙根结构和周围口腔组织受损。
