Repair of washout defects.
Endodontic therapy may be needed after extensive fixed partial denture treatment. When endodontic access preparation is performed through a cast restoration, retention of the restoration is reduced and the underlying abutment structure may be weakened. Eventually, it may give way to cement breakdown and caries, resulting in a washout defect, which can jeopardize the restoration's longevity. This paper describes the clinical management of such a situation using stainless steel prefabricated posts and a bonding cement.
