Long-Term Clinical Management of Recurrent Traumatic Crown–Root Fracture in a Permanent Maxillary Incisor Through Fragment Reattachment: A Three-Year Case Report and Outcome Analysis
Year: 2026
Type: article
Abstract: Traumatic crown–root fractures of permanent anterior teeth represent a complex clinical challenge due to the simultaneous involvement of enamel, dentin, cementum, and, in many cases, the periodontal attachment apparatus. Preservation of aesthetics, restoration of function, maintenance of periodontal health, and prevention of recurrent fracture remain the principal objectives of treatment. Fragment reattachment has emerged as a conservative and biologically favorable treatment modality that preserves natural tooth structure while achieving acceptable esthetic and functional outcomes. Despite advances in adhesive dentistry and trauma management protocols, long-term evidence regarding recurrent traumatic crown–root fractures managed through fragment reattachment remains limited. This research and review article presents a comprehensive analysis of the long-term clinical management of a recurrent traumatic crown–root fracture in a permanent maxillary incisor treated through fragment reattachment and monitored over a three-year period. The study integrates current evidence from dental traumatology literature, evaluates biological and restorative considerations, and examines factors influencing treatment success. The article further discusses diagnostic protocols, adhesive strategies, periodontal management, follow-up assessment, and long-term outcomes associated with conservative fragment reattachment techniques. Findings indicate that successful management depends on accurate diagnosis, preservation of the fractured fragment, appropriate adhesive protocols, periodontal stabilization, and continuous monitoring. Long-term outcomes demonstrate favorable esthetic integration, functional stability, and patient satisfaction when multidisciplinary principles are applied. The study supports fragment reattachment as a viable treatment option for recurrent crown–root fractures while highlighting limitations related to fracture pattern, biological width involvement, and reinjury risk.
