Introduction
The anomalies of shape are the most frequent class of anomaly a general dentist can encounter in the daily practice. The dental anomaly named as double tooth derives from the fusion of two or more adjacent tooth germs during the embryological period. If the fusion is complete, the crown appears clinically large, without any substantial groove. If the fusion is incomplete, the crown appears with a separating groove mainly situated on the vestibular surface. In addition, tooth transposition is an anomaly described as the positional interchange of two teeth in the same quadrant.
Case Description
In the present clinical report, a 15-year-old male patient has visited our clinic with a complaint of a gap between his teeth and an aesthetically unpleasant smile. In clinical and radiological examination, fusion between permanent teeth numbered 21 and 22 and transposition of teeth numbered 11 and 12 have been identified. Department of Orthodontics and Prosthodontics have reached a consensus to close the diastemas in the lower jaw and appropriately distribute the gaps for prosthetic restoration in the upper jaw. After orthodontic leveling and alignment, the gaps in the lower jaw arch were closed. The gaps in the upper jaw arch were also distributed according to the recommendation of the Department of Prosthodontics. The orthodontic treatment was completed in 21 months. Following orthodontic treatment, a 6-unit fixed restoration was planned between the maxillary canine teeth of the patient. Before preparation, root canal treatment was applied to the fused teeth. Following root canal treatment, the preparation of the relevant teeth was completed, and the patient's fixed prosthesis was finalized. Monolithic zirconia was chosen as the material for the fixed partial prosthesis.
Discussion
The patient was satisfied in terms of gingival health, aesthetics, function and phonation of the prostheses at the 1 and 6 month-follow-up periods.
