In this study, the MgTiO3 ceramic system was used in a dry mixing method with 2: 1 mol and was reinforced to white acrylic powder used in dental applications to form a mixture of 1%, 2%, 3%, 4% and 5% of ceramic powder. The ultrasound technique was used to disperse the powder and distribute it homogeneously in the chloroform solution for one hour and then mixed it with acrylic powder in the same technique for half an hour. The tests were done for the samples made using industrial saliva with bacteria. Calculate the rate of wear using Pin on disc method. The results were interpreted based on the resulting images from the scanning electron microscope and the density of the prepared samples.
