Treatment of concomitant geminated and fused maxillary central incisors: A 5-year follow-up

Abstract

Dental anomalies of form, such as gemination and fusion, are conditions rarely observed in the permanent dentition. Multiple anomalies of form are seldom found in one patient. This report describes the rare case of a 9-year-old boy with two dental anomalies, a geminated maxillary right central incisor and a fused maxillary left central incisor. The treatment plan included extraction of the geminated central incisor, and endodontic treatment and surgical separation of the fused central incisor. The correction of the smile was obtained by orthodontic movement of the mesial half of the fused tooth through the midpalatal suture and subsequent aesthetic and prosthetic rehabilitation procedures. A multidisciplinary approach was essential for the proper planning of complex cases to achieve the best result.
