Modern Applications in Technology of Post and Core Restorations

Abstract Post and core devices are elements that contribute to the complete restoration of the coronary abutment, over which the final prosthetic restoration will be created. Their role is to retain the coronary portion of the restoration and to protect the remaining coronary structures. The retention function is dictated by the major indication of the method, massive coronary destruction that does not provide conditions for coronary aggregation of the restoration. Thus, this material is approaching two unique methods of making post and core devices totally metallic and/or hybrid (metal + totally ceramic component), using both classical technology, modern technologies, but also combinations of them.
