Abstract

This study was to compare the tensile bond strength and flexibility of four different soft liners(Coe Soft, Soft Relining, Soft Liner, Dura Base Soft) before & after thermocycling. Each soft liner was bonded to denture base resin block, and measured the tensile bond strength and modulus of elasticity using Universal testing machine. The mean value of tensile bond strength and modulus of elasticity for each experimental groups were statistically processed by SPSS(Statistical Package of Social Sience). The obtained results were as follows : 1. Dura Base Soft had the highest tensile bond strength and Coe Soft had the lowest tensile bond strength. 2. Coe Soft had the lowest modulus of elasticity, and Dura Base Soft had the highest modulus of elasticity of all the soft liners. 3. Thermocycling \ no effects on the tensile bond strength and modulus of elasticity of all the soft liners. 4. The failure modes of Coe Soft, Soft Relining, Soft Liner were mainly cohesive failure and that of Dura Base Soft were mainly adhesive failure.
