The interdisciplinary treatment provided for a 12-year-old boy with fusion of his left central and lateral incisors and concomitant distal space loss is described. His treatment was initiated with orthodontic therapy followed by endodontic treatment of the fused tooth. A conservative zirconia and porcelain cantilevered bonded fixed dental prosthesis was then completed to replace his left lateral incisor.

A 12-year-old boy presented for prosthodontic treatment to correct space and esthetic discrepancies on his left and right sides associated with fusion of his maxillary left central and lateral incisors. (Fig. 1) Periodontal probing of the fused tooth and left canine were 3 mm or less. An esthetic evaluation was completed and detailed measurements were made to determine the difference in spacing between his left and right sides. His dental midline was coincident with his facial midline. His

DISCUSSION

This patient’s treatment illustrates the coordinated efforts of the specialties of orthodontics, endodontics, and prosthodontics to correct a large esthetic discrepancy on the patient’s left anterior maxillary segment associated with fusion of the left central and lateral incisors. Zirconia fixed dental prostheses, with or without facial porcelain application, have been well documented to conservatively treat patients missing 1 anterior tooth.13, 16, 18 The ovate pontic design allowed for a

SUMMARY

The combination of orthodontic, endodontic, and prosthodontic treatment allowed this patient to have a normal appearance for the first time since his permanent dentition with the placement of a conservative bonded fixed dental prosthesis. The goal in providing this treatment was to retain the prosthesis until facial growth was complete. At that time an implant-supported prosthesis to replace the lateral incisor could be considered.
