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.
在进行广泛的固定局部义齿治疗后，可能需要进行牙髓治疗。当通过铸造修复体进行牙髓通路预备时，修复体的固位力会降低，其下方的基牙结构可能会被削弱。最终，可能会导致粘结剂崩解和龋齿，从而形成冲刷性缺损，这可能会危及修复体的使用寿命。本文介绍了使用不锈钢预成桩和粘结剂对此类情况的临床处理方法。
