Introduction We report a case of successful autotransplantation of a premolar impacted with a dentigerous cyst and transplanted with collagen plugs for initial support. Methods An 18-year-old man had an impacted premolar accompanied with a large dentigerous cyst. The tooth was extracted surgically and transplanted to an edentulous alveolar ridge, and a collagen sponge was inserted to ensure proper healing and initial support. Root canal treatment was performed 3 weeks after the surgery. Results The previous lesion was healed, and the transplanted tooth was functional without any pathologic signs. Conclusions Our protocol provides a viable option for saving an impacted tooth in the case of cyst enucleation.
