Objectives: Vertical root fracture is the worst disorder to which tooth extraction is indicated. Vertical fracture causes endodontic-periodontal disease of the tooth, and its prognosis is poor. In recent years, improvement of the adhesive dental material has progressed, and a system which strongly adheres to dentin is used. In this report, the procedures and prognosis of the new treatment for the vertical tooth root fracture tooth reconstructed by intracanal adhesion method by intentional replantation.
Methods: After extracting the vertical fracture tooth, the root canal contents of the broken pieces were removed to the root apex, and root canal dentin was cut along the fracture line from inside the root canal toward the root surface. The interior of the tooth root was cut and removed as much as possible, suction dried inside the enlarged root canal, filled with adhesive core resin, and reinforcing wire was used to prevent refracture. After performing the apicoectomy as necessary, replanting was carried out and temporarily fixed for one week.
The fractured tooth was set full-covered metal crown after 3 month later as a bridge abutment, and 2 years passed and a good prognosis was shown.
Conclusions: Reconstruction with intracanal adhesion with intentional replantation is effective for save the VRF.
