title: The resin-bonded cast post core: technical preparation and cementation protocols.
abstract: Post and core restorations have been widely utilized in the reconstruction of endodontically treated teeth. This study compares the traditional cast post core with the bonded type, and reviews the restoration of devitalized teeth without imposing frictional forces within the root canal walls. Clinical and laboratory aspects are discussed, with emphasis on the cementing procedure. Several resin cements are evaluated and compared to traditional zinc oxide phosphate cement techniques; microleakage test results are presented. The learning objective of this article is to outline the clinical indications, advantages, disadvantages, and the clinical techniques employed for resin-bonded cast post core restoration. A case of an endodontically treated maxillary left central incisor following a direct trauma is used to illustrate the procedure of resin-bonded post core placement. Biocompatibility of the cast post core is confirmed by a radiograph 2 years postoperatively.
