Physical and mechanical properties of different auto-polymerized acrylic resin specimens; each value represents the mean of seven measurements and the error bars show the standard deviation of the mean (meanā±āstandard deviation; nā=ā7). Different lowercase letters above a bar indicate a significant difference at pā<ā0.05. (A) Flexural strength. (B) Elastic modulus. (C) Microhardness. (D) Contact angle.
