In recent prosthodontic procedures in crowns and bridges on endodontically treated teeth, root fractures have become a more critical issue to be discussed since practitioner have often met as many clinical problems associated with the phenomenon as those of dislodgement of post and core. One of the main reasons for this phenomenon may be a mechanical stress concentration on cast post and core which may be caused by a difference of elastic modulus between tooth structure and post core. Hence, as a preventive measure, the use of flexible fiber posts is thought to be effective clinically. Therefore, direct post and core employing stock posts and adhesive resins are now highly recommended to clinicians. However, in Japan, cast metal post and core have been primarily used as laboratory process, and general practitioner may not be used to the direct procedure. There are technical difficulties to the progress of indirect procedure of resin post and core using a fiber post and working cast such as inefficient light curing and the necessity of separating agent application on a cast. Hence, in this particular clinical report, a unique and effective laboratory process technique is introduced and discussed.
