Gemination of maxillary incisors.

Gemination is defined as a shape anomaly of teeth caused by an incomplete division of a single tooth bud. Its aesthetic and functional implications usually require a complex endodontic, restorative, periodontal, surgical, and orthodontic treatments. Three cases of gemination of maxillary incisors, resolved by different therapeutic approaches, are reported. The 1st case (germination of 2.1) was resolved by a simple crown-plasty. The 2nd case (gemination of 1.1 and 2.1) was resolved by a crown-plasty of 2.1 and an interradicular section of 1.1 with extraction of lateral root. The 3rd case (2.2 supernumerary and gemination of 1.2) was resolved by sacrifice of 1.2, extraction of 2.2 and its implantation in 1.2 region. In order to obtain an acceptable aesthetic and functional restoration, as in the cases presented, a good team-work, where all the specialists contribute to the selection of the more suitable treatment possible, is mandatory.
