Abstract

Transverse and oblique crown-root fractures constitute a major therapeutic problem, particularly in young dentitions. Because crown-root fracture may involve enamel, dentin, pulp, and periodontal tissues, management of the injuries must be modified accordingly. When the fracture line was located under the alveolar crest. there are several methods for crown-root fractured teeth with pulp exposure, such as extruding the root fragment with orthodontic force and restoring it, or intentionally extracting the tooth and replanting it to a position which it can be restored. This case, the fractured tooth is intentionally extracted atraumatically, and replanted by rotating approximately 180 degree into the original socket and fixing with an orthodontic wire. At the 8-month recall examination, the root still showed normal mobility and there was not observed any inflammatory or replacement root resorption in the periapical radiograph.

Key Words: Replantation, Crown-root fracture
