Endodontic considerations in restoration of partial overdenture abutments.

Overdenture abutment teeth often require endodontic treatment. Various factors, such as status of the pulp, periodontal state of the tooth, and the sequence of overdenture treatment, influence endodontic management of the patient. After completion of endodontic treatment, the coronal part of the root filling is removed, leaving an adequate amount of the root filling in the apical part of the root canal undisturbed. The abutment tooth is then permanently restored with a filling material, or is prepared for a cast restoration.
