Interdisciplinary management of dental anomalies: fusion and supernumerary teeth.

A 16-year-old boy presented with a fused permanent maxillary left central incisor with a supplemental tooth and an additional supplemental tooth lingual to the permanent maxillary right central incisor. Following leveling, alignment, and endodontic therapy, the maxillary fused left central incisor was sectioned and the mesial portion extracted as planned. Fixed orthodontic treatment commenced after 10 days to align the maxillary anterior segment. After completion, the midline diastema was closed with veneers. This case highlights the treatment options of a fused tooth and the need for multidisciplinary planning and treatment.
