Traumatic tooth injuries are common in children. When permanent teeth are involved, it can be a challenge to save these teeth. This clinical case study describes the multidisciplinary treatment of a complex crown fracture and luxation of a right maxillary incisor along with esthetic management. After periodontal surgery including guided bone regeneration and endodontic treatment, we used a glass-fibre-reinforced composite post to increase retention and distribute stress along the root. The restoration was completed using composite in an incremental technique. During follow-up appointments, clinical and radiographic examinations revealed no root canal or periodontal problems, suggesting the efficacy of the treatment in retaining the fractured tooth. Periodontal surgery with endodontic treatment is an alternative treatment for severe trauma in permanent teeth.
