Dental avulsion is one of the most frequent injuries in permanent teeth and higher complexity in terms of treatment and prognosis. The International Association of Dental Traumatology divides this trauma into several categories and guides the conduct according to each category. The aim of the present study is to report a case of dental reimplantation of the upper central incisor in a patient with incomplete rhizogenesis. An 8-year-old male patient sought care after undergoing avulsion of upper left central incisor and left superior deciduous lateral incisor teeth and subluxation of the upper right central incisor tooth. The upper left central incisor tooth was maintained in dry medium and reimplanted in < 60 min after avulsion. The flexible restraint from the upper right canine deciduous to upper left canine deciduous remained for approximately 21 days. The clinical-radiographic follow-up was periodic and after 34 months posttrauma was observed crown integrity, root growth continuity, calcification of the canal of upper left central incisor, absence of radiographic image compatible with periapical lesion, and negative response to the pulp vitality test in the upper left central incisor tooth. We conclude from the exposed clinical case that, even with predictable sequelae, such as calcification of the root canal space and dental reimplantation is the procedure of choice in cases of dental avulsion.
