摘要

Traumatic dental injuries in the anterior maxilla may result in late complications such as pulp necrosis, periapical pathology, and progressive alveolar bone loss, compromising esthetic rehabilitation. This case report describes the staged management of a traumainduced dentoalveolar defect using guided bone regeneration (GBR) with titanium mesh, soft tissue augmentation, and implant-supported rehabilitation. A 29-year-old female presented with chronic periapical infection and severe alveolar bone loss associated with a previously traumatized maxillary central incisor. Following extraction, ridge reconstruction was performed using autogenous bone combined with xenograft and stabilized with titanium mesh. After 6 months, sufficient bone regeneration allowed implant placement. Connective tissue grafts were used to enhance peri-implant soft tissue volume. A contralateral incisor later required immediate implant placement following vertical root fracture. Final restorations achieved stable functional and esthetic outcomes. Clinical and radiographic follow-up over 5 years demonstrated maintenance of peri-implant tissue health, preservation of hard and soft tissue architecture, and long-term esthetic stability. This case highlights the predictability of staged regenerative strategies for managing complex trauma-related defects in the esthetic zone and supports their long-term success.
