Extrusive luxation results in damage to the periodontal tissues and the apical neurovascular bundle as the tooth is displaced in a coronal direction. Immediate treatment is necessary in order to save the tooth and its vitality, especially in immature teeth.

Aim: To present a clinical case of extrusive luxation and uncomplicated crown fracture of immature maxillary central incisor.

Materials and methods: Eight–year old boy is referred for dental treatment three weeks after he had sustained an injury, which had led to extrusive luxation and uncomplicated crown fracture of the right maxillary central incisor. The tooth is splinted and the exposed dentin is covered with resin modified glass ionomer cement. Loss of vitality occurs two months later, which necessitates conducting an endodontic treatment. Calcium hydroxide is placed in the root canal for one week, followed by creation of MTA apical barrier and filling of the canal with lateral condensation technique.

Results: The provided treatment protocol ensures saving of the tooth without clinical complications. Healing is observed on the follow – up radiographic examination.

Conclusion: Delayed treatment of luxated immature permanent teeth may lead to loss of vitality and disturbance in root development. Mineral trioxide apical plug method is a good alternative of classical apexfication technique using calcium hydroxide when treating permanent teeth with incomplete root development.
