Fusion has been described as a development anomaly characterized by the union of two adjacent teeth. Proper combined endodontic and orthodontic treatment resulted in maintaining one tooth half and solving the aesthetic and functional problem of a fused tooth.

• Autotransplantation is a viable option for the treatment of a missing tooth or for the replacement of a traumatized tooth when there is a donor tooth available. • Autotransplantation of a premolar for replacement of a missing anterior tooth is sometimes a suitable alternative to conventional prosthetic rehabilitation or implant treatment in young individuals. • Proper combined endodontic and orthodontic treatment of autotransplanted teeth might be possible without periodontal complications.

Special techniques of skeletal intermaxillary fixation are described, which may be used in edentulous patients or those with many missing teeth or multiple fractures of the jaw. Two such cases are described in which the usual fixation techniques could not provide sufficient stabilization because of linguoversion and mesioversion or lack of teeth, resulting in inability to maintain a vertical interocclusal relationship.Two long eight-hole Champy miniplates were therefore used distally to the canines on both sides. In the first case, they provided fixation following a sagittal ramus osteotomy to advance the mandible, and in the second case they were used in the treatment of a mandibular fracture.
