Mobilization of malpositioned dental implant using segmental osteotomy: A case report.

By increasing the number of replaced tooth with dental implants, the number of poorly positioned implants is also increased. In this article, we present our experience about a 48-year-old female who was referred to our department for resolving prosthetic problem regarding two malpositioned implants inserted in the upper jaw. The interocclusal space was insufficient and the two adjacent implants had excessive buccal angulation. To overcome these problems, segmental osteotomy of the alveolar bone containing two implants has been done. After palatal and apical repositioning of the bone block, rigid fixation was performed using a 4-hole miniplate and four 5mm monocortical screws. Two weeks after the procedure, a conventional fixed prosthesis was constructed with regard to the esthetic and functional aspects. During the two-year follow-up, the patient was satisfied with the result and there were no complications, such as alveolar bone necrosis, marginal bone loss, implant failure or infection.
