Wear resistance properties of the commercial acrylic based artificial teeth

Abstract

Wear resistance properties of different brands of commercially available acrylic based artificial teeth were carried out in the presence of artificial saliva at the body normal temperature (37 oC) under the applied load of 64N by using pin-on-disc tribometer, fabricated in our laboratory. All the tested samples showed different values of the wear resistance property. Att empts were made to correlate wear resistance properties of these teeth with cost of the teeth. This study gave us some indication that the teeth with high price showed better performance, with the exception of the teeth brand 1 (brand name- Welbite), which sho wed good performance despite of their low price. The variation in wear resistance performance of these teeth was in fact attributed to the variation in quality of the teeth precursor material, properties of the filler particles, blending/ molding process of the finished product, etc.
