Immediate autotransplantation of a mandibular premolar with complete roots to a fractured tooth site, using platelet ‑rich fibrin in an orthodontic patient, report of a case

This study reports the treatment results of a16 ‑year‑old female with severe crowding in upper and lower arches and a fractured mandibularpremolar with a poor prognosis. The crowding of the lower left quadrant was relieved by theextraction of the first premolar. This extracted tooth with a complete root was transplanted to theright quadrant with the fractured tooth. Platelet ‑rich fibrin can stimulate and accelerate periodontalhealing. The platelet concentrate of this patient was prepared and applied to the socket wall at thetime of surgery. The acceptable occlusion and the excellent 4 ‑year prognosis of the transplantedtooth are presented.Key Words: Autologous, platelet ‑rich fibrin, tooth fracture, transplantation
