Bilateral dental fusion of the upper central incisors: a multidisciplinary approach.

UNLABELLED: The multidisciplinary treatment of a case of bilateral dental fusion of the upper central incisors with maxillary constriction, crowding, and palatal inversion of one of the lateral incisors is reported. The rarity with which this anomaly appears, along with its complex characteristics, often make it extremely difficult to treat. It requires the involvement of different specialists to find the most suitable treatment for each individual patient. CLINICAL SIGNIFICANCE: This particular case of bilateral dental fusion required the involvement of orthodontists, periodontists, endodontists, and restorative specialists. For the individual evaluation of these extremely complex cases, the esthetic and functional results to be reached must be assessed compared to treatment times and biologic and economical costs. The long-term prognoses of these complex therapies also must be borne in mind.
