Abstract
Aim: In clinical practice, a material called adhesive is frequently applied over the impression tray to adhere impression materials to it. This prevents dislodgement of material which causes distortion of the impression made. This study aimed to compare the tensile bond strengths of polyvinyl siloxane impression material to auto-polymerizing custom tray using different tray adhesives.
Materials and Methods: A total of sixty uniform blocks of auto-polymerizing custom tray specimens were built using a mould made of stainless steel. They were coated with one of the four adhesives (manufactured by 3M ESPE, Coltene-Whaledent, Ivoclar Vivadent, GC) and the force at which separation failure occurred was measured using Universal testing machine.
Result: The results found that any of the commonly used adhesives (manufactured by 3M ESPE, Coltene-Whaledent, Ivoclar Vivadent, GC) can be used for application on auto-polymerizing custom trays before polyvinyl siloxane is added to the tray, however, tray adhesive by Coltene-Whaledent (Adhesive) was found to have the best bond strength followed by tray adhesive from GC (Vps Universal Tray Adhesive).
Conclusion: Tray adhesive by Coltene-Whaledent (Adhesive) has the best bond strength followed by tray adhesive from GC (Vps Universal Tray Adhesive).
