title: Long-term Stability of Autotransplanted Premolars as a Substitute for Molars in Adults.
abstract: Autotransplantation is a viable treatment option for tooth replacement when a suitable donor tooth is available. This case report presents 2 cases that describe successful treatment outcome and prognosis after autotransplantation of a mature premolar as a missing molar. The first premolar was extracted for orthodontic purposes and transplanted to the missing first molar site in the mandible. The transplanted tooth was monitored up to 7 years. The transplant was functional and maintained a normal bone level throughout the follow-up period. Clinical examination showed normal physiologic movement without any signs of ankylosis and root resorption. Autotransplantation of a mature premolar to a molar site is a viable treatment option showing successful results. The selection of a functional donor tooth, adequate surgical procedures, and timely application of orthodontic movement may have positively contributed to the favorable prognosis.
