Vital root submergence of immature permanent incisors after complicated crown-root fracture followed by orthodontic space maintenance: A presentation of two cases

Complicated crown-root fractures are considered rare occurrences in young permanent dentition; however, they pose a particularly difficult clinical challenge, especially when the traumatized tooth is immature. Two cases of complicated crown-root fractures of immature incisors are presented. In both cases, vital root submergence with no treatment to the exposed pulp was introduced as a stage in a complex treatment plan with the primary goal of preserving the shape of the alveolar ridge in the traumatized area until the root was completely formed or facial growth was finished. No inflammatory symptoms were detected either radiographically or clinically during the 15- and 16-month follow-up periods. In the chosen clinical cases, vital root submergence followed by orthodontic space maintenance can be beneficial to young patients if other treatment options are limited by the depth of the crown-root fracture or if the patient suffers from high dental fear and presents a particularly low level of compliance.

Key words
