Autogenous tooth transplantation by using the undersized thi
The study result shows that the third molar can be used as the donor tooth for autogenous tooth transplantation. It was published in Oral Surgery.

The aim was to explore the clinical effect of autogenous tooth transplantation with the undersized third molar as a donor tooth.

The general situation, donor tooth, and recipient area, timing of the operation, intraoperative and postoperative treatments, and curative effect evaluation of 11 patients undergoing autogenous transplantation of the third molar were analyzed retrospectively.

Among the donor teeth, 8 were located in the maxilla and 3 in the mandible. In the recipient area, 7 affected teeth need 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 success rate was 90.91% and the survival rate was 100%.

In summary, the third molar can be used as the donor tooth for autogenous tooth transplantation with a higher success rate.
