Spontaneous reeruption after intrusive luxation of the permanent incisors by incomplete root formation. Two case...

In the context of tooth trauma mostly the maxillary central front teeth are involved, whereby their roots are in some cases in developing stage (immature). The intrusive luxation represents one of the most severe types of dental trauma because of the damage to the periodontal ligament, alveolar bone and pulp. Principally, three different treatment options are available: 1. Spontaneous reeruption, 2. orthodontic extrusion, 3. surgical repositioning. This report is aiming to illustrate, by two cases, that traumatic intruded teeth with incomplete root formation, treated without active repositioning (waiting for spontaneous reeruption), seem to be associated with the lowest risk of healing complications. Therefore, the decision of the treatment procedure should be based mainly on the stage of root development and only secondarily on the degree of intrusion.
