Background: Implant supported crowns can either be screw retained or cement retained. Recent advances in implant dentistry has improved the longevity of the implant restoration and has placed importance on esthetics and function. Cement retained restoration has added advantage of superior esthetics and is preferred by the clinician. However, selecting the ideal type of cement for luting implant supported crown has been a topic of debate. Methodology: A study was conducted at ESIC Dental College & Hospital, Kalaburagi to determine the retentive ability of three different luting agents. 30 samples were divided into three groups and luted with Zinc phosphate, Zinc Polycarboxylate and Glass ionomer cement. The retentive strength was evaluated using universal testing machine. Results: Results proved that zinc poly carboxylate cement had the highest retentive value followed by glass ionomer and zinc phosphate.
