The longevity of endodontically involved teeth has been greatly enhanced by continuing
developments made in endodontic therapy and restorative procedures. It has been reported that a large number of endodontically treated teeth are restored to their original function with the use of intraradicular devices. These devices vary from a conventional custom cast post and core to one visit techniques, using commercially available prefabricated post systems. In the last few decades, various prefabricated posts systems have been developed. The selection of post design is important, because it may have an influence on the longevity of the tooth (Sorensen JA et al 1990).
