Different outcomes of managing severe intruded immature permanent incisors: A report of two cases

Abstract

Intrusion is a very severe injury involving damage to the periodontal ligament, cementum, alveolar bone, and neurovascular pulp supply. Current management strategies include passive repositioning by waiting for the tooth to regain its preinjury position, and active repositioning, i.e., immediate surgical repositioning or repositioning with traction. This report describes the interdisciplinary management of complete intrusions of the maxillary right central incisors with an immature open apex in 2 different patients of a similar age but with different outcomes. The most likely causes of these differences were: ankylosis; inflammatory root resorption; and the systemic condition of the 2nd patient. A number of preinjury and injury factors have a significant influence on the healing outcome. According to this report, prognosis after intrusive luxation appears to depend not only on the severity of the trauma, stage of root development and treatment method, but also probably on the patient’s systemic condition. Therefore, the patient’s current complex medical history should be taken into consideration as a factor significantly affecting the healing outcome and long-term prognosis.
