Management of traumatically intruded immature permanent incisor

Abstract

Intrusive luxation injuries often result in severe damage to the tooth itself and surrounding tissues. Furthermore, treatment outcome is often unpredictable because of the large number of injury-related variables (such as time passed, patient age, comorbidities and related treatment, and patient cooperation) which influence the choice of treatment and prognosis. This report presents the case of an 8-year-old boy with a severely intruded immature permanent upper incisor combined with missing alveolar socket wall. The treatment option chosen by the parents was to replace the tooth and fix it by glass fibers as splinting material. Four months after the trauma, the tooth was vital and asymptomatic, and radiographic examination showed satisfactory periapical and periodontal healing. The outcome of the presented case highlights the importance of the timely and properly performed management together with the regular long-term follow-ups for the survival rate of severely intruded immature teeth, even with a missing supporting alveolar wall due to the facilitated revascularization through their wide open root foramina.
