Regenerated treated incisors subjected to orthodontic movement

---

With an increasing number of anterior traumatized teeth treated with regenerative endodontic procedures nowadays, orthodontic movement of such teeth is expected to become a common scenario in everyday clinical practice. However, little is known about the clinical implications and the response capacity of regenerated tissues to orthodontic forces.

The aim of this clinical article was to report on four cases of regenerative endodontic procedure (REP)-treated immature anterior permanent teeth subjected to orthodontic forces. Authors aimed to describe the long-term response of the regenerated apical and intracanal tissues.

Signs of orthodontic-induced external root resorption were observed in two of the four presented cases without, however, the presence of any associated adverse events. No other complications were observed, either clinically or radiographically, throughout the observation period.

In the long term, all four cases responded favorably to orthodontic forces, maintaining healthy apical tissues and structural integrity of both intracanal as well as apically regenerated tissues.

The orthodontic movement of REP-treated teeth seems feasible, nevertheless, special care should be implemented.

Lightly acting orthodontic forces, short duration of active movement and close monitoring of the patient seem to be prerequisites to limit complications to a minimum and achieve a favorable healing of REP-treated teeth in the long-term following orthodontic treatment completion.
