Management of Complicated Crown–Root Fracture

Abstract Crown–root fractures are traumatic injuries that frequently extend below the gingival margin and present restoration complications due to biologic width violations, isolation issues, and structural loss. In this case report, a 16-year-old boy presented with fractured maxillary lateral and central incisors 24 h after trauma. Cone-beam computed tomography imaging revealed a complex crown–root fracture of the tooth with palatal subgingival extension. After stabilizing the fragment, root canal treatment was performed, a full-thickness flap was elevated, and the margin was exposed using osseous recontouring. A crown made of lithium disilicate was luted with resin cement. A 1-year follow-up revealed stable periodontal and periapical health with satisfactory esthetics and function.
