Abstract

Intrusive luxation that takes approximately three percent of permanent teeth commonly occures at anterior teeth. This intrusion frequently leads to pulp necrosis, root resorption, marginal bone loss and these complications are influenced by depth of intrusion and stage of root development. Various treatment approaches have been suggested to manage of intrusive luxation. Techniques aiming to reposition the intruded tooth include an observation for spontaneous re-eruption, surgical or orthodontic repositioning. We report two cases with clinically satisfactory results for traumatically intruded maxillary central incisor. In one case which has a large open apex and mild intrusion depth, we observed for spontaneous eruption and then repositioning by forced eruption method. In other case, which has been completely intruded, was repositioned by surgical extrusion and followed by apexification.

Key Words: Traumatic intrusion, Forced eruption, Surgical reposition
