Provisional cements are used to facilitate retrievability of cement-retained fixed implant restorations. While the relative retentiveness of various provisional and permanent cements has been investigated, the functional life span of these cements is not well documendted. The purpose of this study was to assess the effects of pre-fatigued damage on remaining cement bond strengths. Twelve Brånemark fixtures were embedded in epoxy resin blocks. Cera-One closed-end gold cylinders were cemented with three types of luting cements including ImProv, UltraTemp, and Temp-Bond. Each couples was subjected to cyclic loading at 110 N and a frequency of 80 cycles/rain for 50,000 and 300,000 cycles. Then each cylinder was pulled from the abutment, and the force required to remove the gold cylinder was recorded It was found that ImProv was the most retentive before and after the two cycles, and Temp-Bond was the least retentive. UltraTemp had the highest percentage (27.2 %) of retentive value lost after the second cycle; ImProv was second with 20.8% lost. Temp-Bond had no significant. It was suggested that Temp-Bond luting agent would be the material of choice for provisional cementation, because it allows easier removal of the prosthesis and maintains enough retention to prevent loosening of the restoration.
