Clinical of abutment build up with composite resin and fiber post

Abstract

Post and core restoration can compensate for loss of tooth structure and permits restoration of an abutment tooth into a suitable shape for the attachment of crown restoration devices. It is therefore a procedure of considerable clinical significance. Abutment build-up with composite resin has many advantages compared to metal casting abutment. Based on previous clinical studies, we have drawn up clinical guidelines to build-up an abutment for an endodontically treated tooth from the remaining coronal tooth structure, presupposing the use of a bonding agent. These clinical guidelines are classified from I to V, according to the amount of remaining tooth structure. The results indicate the amount of remaining structure necessary for post-hole preparation. They also indicate the usefulness of composite build-up and a fiber post.
