Autotransplantation of a first premolar with buccal root amputation using a 3-dimensionally printed replica of the donor tooth

This case report presents the successful treatment of a woman (aged 23 years) with unilateral molar Brodie bite, crowding, midline deviation, and a convex profile. The extraction of two maxillary premolars was performed to establish facial esthetics. Three-dimensional printing-assisted autologous tooth transplantation was performed to replace the residue root of the mandibular left first premolar with the extracted maxillary left first premolar. Accurate recipient socket preparation, minimum extraalveolar time of the donor tooth, and better fitting were ensured via a digital setup and 3-dimensional printing technique. The total treatment procedure was performed over 46 months. After a 3-year follow-up, the transplanted tooth remained healthy and stable.
