title: Traumatic intrusion of maxillary permanent incisors into the nasal cavity: report of a case.
abstract: Complete intrusion injuries in the mixed or permanent dentition are relatively rare and represent one of the most serious injuries to the periodontal ligament in dental traumatology. This paper describes the case history of a 7-year-old boy who sustained displacement of central incisors into the nasal cavity. Surgical repositioning was undertaken and a splint was placed.
