Abstract
Background: Acrylic resin is a common material which is frequently used for denture in dentistry. It has different resin based on its curing method. Cold curing acrylic resin is one of them. This material has the benefit of short curing period, even though mechanical properties were compromised. However the lack of mechanical properties could be improved by increasing acrylic base plate. Purpose: The aim of the study is to investigate the difference between transverse, compressive, and tensile strengths of cold polymerized acrylic resin material with various thicknesses. Method: This study was an experimental laboratory study with one way ANDVA statistical analysis. A total of 40 specimens of cold polymerized acrylic resin were fabricated. Result: The results of the study showed that the transversal strength of acrylic resin with a thickness of 1 mm was 110.15 N / mm2, thickness of 1.5 mm was 112.01 N / mm2, thickness of 2 mm was 118.00 N / mm2 and thickness was 2.5 mm. 116.82 N / mm2. The results of the compressive strength of cold polymerized acrylic resin with a thickness of 1 mm was 22.42N / mm2, thickness of 1.5 mm was 35.09 N / mm2, thickness of 2 mm was 52.15 N / mm2 and thickness of 2.5 mm was 114.48 N / mm2. The results of the tensile strength of cold polymerized resin with a thickness of 1 mm was 30.01 N / mm2, thickness of 1.5 mm was 34.98 N / mm2, thickness of 2 mm was 43.98 N / mm2 and thickness was 2.5 mm. 49.67 N / mm2. Conclusion: The thickness addition on the cold polymerized acrylic resin plate has an effect on transverse strength, compressive strength and tensile strength. At a thickness of 2 mm it has the greatest transverse strength. At a thickness of 2.5 mm it has the greatest compressive strength and tensile strength.
