Single-tooth dento-osseous osteotomy is known to be one of the orthognathic surgery. Advantages of this method are speed of treatment, the ability to move segments in any direction and perform under local anesthesia, and elimination of long-term retention appliance, and improved stability. So it can be considered to be a effective method for malposition of individual tooth.<BR>Four cases of ankylosed anterior maxillary tooth have been treated with single stage surgical technic for immediate reposiotioning of single-tooth dento-osseous osteotomy. In these cases, conventional orthodontic treatment did not work at all.<BR>Incision was made at the labial mucosa slightly away from buccogingival sulcus and reflected as a full-thickness mucoperiosteal flap. Then we ascertained macroscopically the apices of ankylosed tooth and interdental area. Buccal vertical interdental osteotomies were made, horizontal osteotomies extended at least about 5mm above the apices of the ankylosed tooth. The single-tooth dento-osseous segment were then fully mobilized and repositioned desirable posotion. Fixation was accomplished with activated wire tooth bracket.<BR>Occlusal deformities by ankylosed tooth have been successfully corrected by single-tooth dento-osseous osteotomy. Healing of the soft tissue and bony incisions was uncomplicated. Postoperative radiographs show consolidation of the osteomised segments. No relapse, tooth mobility and root resorption was existed. Only one case, we recognized increase of cervical resorption which had been existed before operation.
