Retrievability of cemented implant-supported fixed prosthesis is desirable. Objectives: Compare retentive force of several provisional luting agents when used with cemented superstructures and one implant system. Methods: Five ITI solid screw implant fixtures and solid conical abutments with 6º taper were used. Five metal ceramic crowns were fabricated and cemented with five different provisional luting agents named Tem Bond, Temp Bond NE, Fynal, TNE, and ImProv. Tensile retentive force necessary to debond each casting was measured 30 minutes after cementation in a dry condition (n=10) and after storing and thermocycling for 72 hours (5-55ºC) in artificial saliva (n=10). Mean and standard deviation of retentive force was calculated for all cements. Data were statistically analyzed using two way analysis of variance at 5% level of significance. Tukey’s post hoc test was performed. Statistical software (SPSS, v.16) was used for data analysis. Results: This study provided a rank order of different provisional luting cements according to their ability to retain crowns. Storing and thermocycling of specimens in artificial saliva for 72 hours caused significant reduction in the retentive values of all provisional luting agents investigated. Conclusion: The results may help the clinicians for selecting luting agent, retentive enough
