An endodontic-orthodontic technique for esthetic stabilization of externally resorbed teeth.
Previous studies reveal that external root resorption is often coincident with orthodontic therapy. Some investigators have reported that root resorption ceases when orthodontic therapy is terminated. However, this is not always the case. The purpose of this article is to present an 11-year history of an unusual case in which root-resorptive processes continued for 3 years after orthodontic treatment had been discontinued. The article also describes and discusses a combined endodontic-orthodontic approach to halt external root resorption and stabilize mobile maxillary anterior teeth. Calcium hydroxide therapy was instituted to inhibit inflammatory apical root resorption. A rectangular orthodontic wire was adapted and inserted intracoronally to splint the teeth esthetically. The advantages and disadvantages of this intracoronal splinting technique are compared with other extracoronal splinting methods. Examination of one-year recall radiographs suggested inhibition of the root resorption. Masticatory function was restored for the patient. Considerations for monitoring patients with this problem are discussed.
