One of the most common areas affected by trauma in the mouth is maxillary central incisors. Case Presentation: A10-year-old boy fractured his maxillary central incisors. The fracture line involved the pulp and extended subgingivally on the palatal aspect invading the biologic width. The procedure used to manage this case included endodontic treatment of residual teeth and surgical extrusion to move the fracture line above the alveolar bone. Finally, the teeth were restored with composite build-up. Conclusion: During 24-month follow-up period, the teeth did not show any signs of root resorption. Therefore, surgical extrusion is recommended as a treatment option for crown/root fractures.
