STATEMENT OF PROBLEM: Retrievability of cemented implant-supported fixed prostheses is desirable. Retentive strengths of new provisional luting agents have not been reported. PURPOSE: This study compared the tensile bond strengths of 6 provisional luting agents when used with cemented superstructures and 1 implant system. MATERIAL AND METHODS: Ten castings were fabricated and randomly paired with abutment specimens. Castings were cemented and the assemblies were stored in distilled water at 37 degrees C for 48 hours. Tensile bond strength necessary to remove each casting was measured with a 500-kg load and a crosshead speed of 0.5 cm/min. Crown/abutment specimens were cleaned after testing, and the testing procedure was repeated for a total of 6 luting agents (n = 10). Data were analyzed with 1-way analysis of variance and Scheffé's analysis (alpha=.05). RESULTS: Tensile bond strengths ranged between 1.29 and 4.08 MPa. The lowest tensile bond strengths were found to be statistically similar between Temp Bond and Provilink luting agents. Neo-Temp luting agent exhibited the highest tensile bond strength (P <.01). CONCLUSIONS: Temp Bond and Provilink luting agents exhibited the lowest mean tensile bond strengths. Neo-Temp luting agent exhibited a tensile bond strength more than 3 times that of Temp Bond luting agent.
