Management of a severely extruded immature permanent maxillary incisor: A case report and 6-year follow-up

Background: Extrusive luxation, also known as partial avulsion, refers to the partial displacement of a tooth out of its socket following the application of an oblique or axial force. This type of dental trauma often results in disruption of the periodontal ligament and neurovascular supply, predisposing the affected tooth to pulp necrosis, root resorption, or arrest of root development—particularly in immature teeth.Case presentation: This report describes the immediate management of a moderately severe extrusive luxation injury involving an immature permanent maxillary central incisor. The tooth was promptly repositioned into its socket and stabilized using a flexible splint. The patient was followed up periodically, and at the six-year review, the tooth remained asymptomatic with normal color and function. Radiographic assessment demonstrated continued root development, an intact lamina dura, and absence of periapical pathology, although partial pulp canal obliteration was evident.Conclusion: Favorable outcomes in extrusive luxation depend largely on prompt diagnosis, immediate repositioning, and appropriate splinting. Early intervention and long-term monitoring are crucial to preserving vitality and ensuring optimal periodontal healing.
