[1] The use of this material is very popular because it has several advantages such as light, biocompatible, aesthetic, relatively cheap, low water absorption, easy to manipulate, polish and repair, [1,2,4,5] but this material is not yet ideal in fulfilling the mechanical requirements of a denture base because it has a relatively low impact strength, transverse strength, and modulus of elasticity, making it more susceptible to failure during clinical use.
The problems occurring during the investigation of impact strength of adhesive joints are associated with large discrepancies of research findings and their low repeatability on test machines manufactured by different producers [2, 11, 12].
