Statement of Problem: Very few studies have been conducted on the comparative evaluation of bond strength of elastomeric impression material to custom tray material using two different universal adhesive systems. Materials and Methods: A special mold was made for the fabrications of 24 samples of tray resin materials. They were divided into two main groups of 12. Perforations followed by adhesive application were done according to the grouping of samples. Polyvinyl siloxane material (medium body) was placed over the samples. A universal testing machine with a crosshead speed of 5 mm/min was used to determine the tensile bond strength of tray resin samples to medium body impression material by using different universal adhesives. Based on these values, Student's “t” test, group statistics, and ANOVA test were applied. Results: By using analysis of variance, there was no significant difference between the strength of bonding of tray resin material and medium body addition silicone by different adhesive systems. Conclusion: It was concluded that Medicept Universal tray adhesive system is as good as 3M™ universal tray adhesive system to achieve a good bond between tray resin and medium body addition silicone.
