外側皮質骨分割により埋伏下顎第二,第三大臼歯の抜歯を行った1例

The extraction of impacted mandibular third molar is a frequently performed as minor oral surgery. We report a case of the extraction of impacted mandibular second and third molars by sagittal splitting method. A 31-year-old woman referred to our hospital because of the pain and the swelling of right mandibular angle. She was diagnosed as pericoronitis of second and third molar of the right mandible. Panoramic radiograph revealed that the second molar was impacted in the lower region of the mandible. We judged that it was difficult to extract this tooth by a normal method. Then, we extracted by sagittal splitting of the lateral cortical bone under general anesthesia. The course after the operation was good and the paresthesia of right mental region did not appear.
