When inadequate tooth structure remains for retention of a restoration, clinically acceptable method is the fabrication of a post and core. For many years, cast post and core. For many years, cast post and core has been in practice even they were time consuming. Prefabricated posts came into practice that seemed to be time saving and economical. Present study compares the retention of three different prefabricated post systems. Group I (control group) : Custom Cast Posts. Group II, III and IV : Prefabricated Para Post, Titanium threaded posts and Fiber glass posts respectively. Group III (titanium threaded posts) showed maximum retention values followed by custom cast posts para posts and galss fiber posts in descending grades of retention.
