Objective: To compare microleakage and retention of all-ceramic crowns cemented to zirconia implant abutments using three different luting agents. Material and Methods: 42 internal hex zirconia abutments were assembled on 42 Implant Directs Legacy then lithium disilicate ceramic crowns with overhanging margins were fabricated and cemented to their corresponding assembly. All specimens were stored in water at 37°C for 24 hours then subjected to 3500 thermocycling. The all-ceramic crowns were pulled off to accomplish the retention test. The microleakage between all crowns and zirconia abutments was measured after immersed in 2% basic red fuchsine dye then were assessed using binocular stereomicroscope at each margin. Results: Descriptive statistics showed that the highest mean value retentive strength of Rely-x cement (383.44±19.69 N), then Ketac-Cem (130.57±9.37N) and lowest mean value of Temp-Bond luting cement was (74.67±9.57 N). Rely-x demonstrated the least microleakage while Tembond was the worst microleakage value. Conclusion: Resin modified glass ionomer Rely-x demonstrated the highest mean retentive strength. Resin modified glass ionomer Rely-x had the best sealing properties. The temporary cements Tempbond NE showed more microleakage than those Rely-x and Ketac-Cem.
