Root perforation associated with the use of a miniscrew implant used for orthodontic anchorage: a case report.

AIM To highlight one of the possible complications associated with the inter-radicular placement of orthodontic miniscrews. SUMMARY This case report describes the endodontic treatment and surgical repair of an iatrogenic root perforation involving a maxillary first molar tooth following the placement of an orthodontic miniscrew placed for anchorage purposes in the treatment of an adult patient. The orthodontic treatment plan was completed. The long-term follow-up shows a successful treatment outcome. KEY LEARNING POINTS Inter-radicular placement of orthodontic miniscrews is a valuable source of anchorage in the treatment of orthodontic patients. Root perforation is a possible complication from inter-radicular placement of orthodontic miniscrews. Root perforation can be successfully treated, but may involve apical surgery.
