Investigating the Effect of Chewing Force and an Abrasive Medium on the Wear Resistance of Composite Materials by Chewing Simulation

Various composite materials used as biomaterials were tested by 20-, 50-, and 80-N chewing forces in distilled water and a poppy seed medium by using a computer-controlled chewing simulation procedure. In each chewing test, steatite balls 6 mm in diameter were used as an antagonist material. The mean volume loss of worn surfaces and the surface roughness of the composite materials was measured with a contactless 3D profilometer.
