Late Reimplantation after Tooth Avulsion: Clinical and Tomographic Success with 3-Year Follow-up

Avulsion of permanent teeth is one of the most severe traumatic injuries and can significantly compromise the aesthetics of the smile, impacting the individual’s social interactions, in addition to causing damage to the periodontal ligament, pulp, and, in some cases, the alveolar bone. Ideally, the reimplantation of avulsed teeth should be performed within 60 minutes for a favorable prognosis. Therefore, the aim of this case report was to describe a rare case of successful late reimplantation, performed after 12 hours outside the socket and improper storage, in which, through a cone-beam computed tomography performed three years after treatment, the absence of periradicular lesion and root resorption was confirmed. This late reimplantation case demonstrates that even under unfavorable conditions such as improper storage and prolonged time out of the socket, a satisfactory result can be achieved. However, when deciding on late reimplantation after an avulsion, it is essential to inform the patient about the requirements, options, and commitment involved, as the prognosis of reimplantation depends on multiple interrelated factors that can vary considerably from case to case.

KEY WORDS: avulsion, dental trauma, delayed tooth reimplantation.
