Abstract
This clinical report presents three cases of autogenous tooth plantation of wisdom tooth to replace missing premolar. In the first case, the lower wisdom tooth was transplanted to replace the upper premolar; in the second case the upper wisdom tooth to replace the upper premolar; and in the third case the upper wisdom tooth to replace the lower premolar. During the 3～7 year follow-up, all three cases have seen no trouble such as root resorption. Though wisdom teeth suitable for the replacement of premolars are rarely available, these cases suggested possibilities of autogenous tooth plantation to replace a missing premolar. As presented in the forth complementary case, at my clinic, if a wisdom tooth suitable for such autogenous transplantation is found in the patient's mouth, the patient would be communicated about the possibility of the future possibility of transplantation though maintenance of sound dentition and prevention of periodontal disease are of the utmost priority. This clinical policy is in line with the philosophy of the Japan Health Care Dental Association, namely, always taking into consideration the possibilities of trouble in the future and preparing for life-long oral health.
