Abstract
AbstractAimTo explore the clinical effect of autogenous tooth transplantation with the undersized third molar as a donor tooth.Material and methodsThe general situation, donor tooth and recipient area, timing of the operation, intraoperative and post‐operative treatments and curative effect evaluation of 11 patients undergoing autogenous transplantation of the third molar were analysed retrospectively.ResultsA total of 11 patients undergoing autogenous tooth transplantation, including 4 males and 7 females, with an average age of (34.9 ± 7.5) years. Among the donor teeth, 8 were located in the maxilla and 3 in the mandible. In the recipient area, 7 affected teeth needed to be extracted because they could not be reserved, and 4 teeth had been extracted. The recipient area was located in the anterior area in 2 patients, the premolar area in 6 patients and the molar area in 3 patients. Six patients underwent simultaneous tooth extraction and autogenous tooth transplantation, 5 patients underwent two‐stage transplantation, and all patients underwent elastic fixation of the transplanted teeth. During the operation, 8 patients only underwent soft tissue preparation, 3 patients underwent soft and hard tissue preparation, and 4 patients underwent guided bone regeneration. All 11 patients underwent improved root canal treatment, of whom, 9 patients underwent crown restoration. The mean post‐operative follow‐up time was (24.82 ± 16.41) months, the success rate was 90.91% and the survival rate was 100%.ConclusionsThe third molar can be used as the donor tooth for autogenous tooth transplantation with a higher success rate.
