Intrusive luxation: Spontaneous re-eruption of permanent teeth with incomplete root formation case report

Abstract

Intrusive luxation defined as an axial displacement of a tooth into its own socket, is one of the most severe types of dental trauma. When intrusion occurs in permanent teeth, it could potentially lead to healing complications, such as pulp necrosis, inflammatory radicular resorption, ankylosis, loss of marginal bone support, pulp canal obliteration, paralysis or disturbance of the radicular development and gingival retraction. Management is based on both clinical and radiological diagnosis.Passive repositioning or spontaneous re-eruption is reserved to the immature teeth in first intention, however this passive method requires a regular monitoring.The purpose of this article is to report a case of an intrusive luxation of both upper permanent immature central incisors which re-erupted within one month with a 18 month follow up.
