The restoration of endodontically treated teeth.

Procedure Following nonsurgical root canal treatment, a post space is created in the root canal by careful removal of the coronal canal obturating material. A sufficient amount of material must be retained in the apical portion of the canal to maintain an adequate apical seal. A custom or proprietary post is fitted and cemented into the root canal for core retention. The post should be passively retained and is cemented and/or bonded into place so that no voids exist between the post and the surrounding tooth structure and root canal filling material. Preparation of the post space and placement of the post should be accomplished using an aseptic technique with dental dam isolation.
