**Abstract**

A tooth that has been properly treated endodontically should have a good prognosis. It can resume full function and if necessary serve satisfactory as an abutment for a fixed and removable partial denture. However special techniques are needed to restore such a tooth. Traditionally, a pulpless tooth received a dowel or post to "reinforce" it and a crown to "protect" it. Until the introduction of ZnPO4 cement in the last century. The major problem with their use was that of post retention. Currently, the clinician can use a variety of port and core systems for the different endodontic and restorative requirements. However, no single system provides the perfect restorative solution for every clinical circumstance, and each situation requires individual evaluation.
