Abstract Aim: The aim of this RCT is to compare the effect of using two different techniques in manufacturing copings in telescopic overdenture retained by two dental implants in the interforaminal region on patient satisfaction and retention Methods: 20 completely edentulous patients were randomly divided into two equal groups: (10 patients each). group I (The Control group) For patients in this group, the secondary crowns of the telescopic overdenture were made of Cast metal copings hand free technique. group II (The intervention group) For patients in this group, the secondary crowns of the telescopic overdenture were made of cast metal copings by indirect 3d printing. Results: There was a significant difference in overall retention forces between observations. There was no significant difference in overall retention forces between groups. There was a significant difference in patient satisfaction between observations. There was no significant difference in patient satisfaction between the groups. Conclusion: Indirect 3D printing can be an alternative to conventional free hand waxing up of Co-Cr copings to save time taking into consideration increased cost and complex workflow.
