Complicated Crown-root Fracture Management Using the 180-degree Rotation Method

Abstract

Aim: The aim of this article is to report a successful treatment of a complicated crown-root fracture. Background: The management of complicated crown-root fracture in young patients is challenging as the fracture line is below the bone crest and the pulp is exposed. Treatment options include crown lengthening, orthodontic extrusion, and intentional replantation. Case description: Here, a case of complicated crown-root fracture of tooth number 11 in a ten-year-old boy is presented. Intentional replantation with 180° rotation and slight extrusion and fixation was performed. In addition, root canal therapy was done and tooth was restored with a composite resin after four weeks. The patient was asymptomatic clinically and radiographically after three-year follow-up. Conclusion: Intentional replantation with 180° rotation is a valuable treatment for crown root fractures. Clinical significance: The management of complicated crown-root fracture using intentional replantation with 180° rotation can help to maintain natural dentition and interdental papilla.
