Abstract : This case report describes the procedures and prognosis of internal adhesive treatment and intentional replantation for maxillary premolars with crown/root fracture. Two cases with buccal and lingual fragments caused by crown/root fracture are presented : one was a vital tooth and the other was a non-vital tooth. The teeth were extracted and stored in commercial balanced saline solution. The two fragments were repositioned, and the fracture surface was removed from the internal canal using a micromotor with a long carbide bar until the bar was visible. The cavity was dried using a capillary suction tip and treated with dentin conditioner. Dual-cure core resin and a 0.9-mm U-shaped orthodontic wire were used to fill and reinforce the root canal cavity. The end of the root apex was retrofilled with composite resin and replanted in the socket. The patient's prognosis was favorable and the teeth retained occlusal function at the 3-year follow-up. Our results showed that intentional replantation after internal adhesive treatment with dual-cure resin and a metal wire is an effective and practical treatment for crown/root fracture of maxillary premolars.
