However, it has been revealed that most failures of fixed prosthetic restorations with endodontically treated teeth are caused by unsuitable post and core. The causes of these failures are based on both wrong judgement of indication and faulty procedure for constructing post and core. This article describes the following clinical criteria for the use of post and core; (1) retention of post and core, (2) mechanical strength of post and core, (3) retention of restoration retained by post and core, (4) tooth fracture, and (5) secondary caries and periodontal diseases.}, pages = {191--205}, title = {失活歯の支台築造}, volume = {13}, year = {1987} }
