Research on the Friction and Wear Test between Dental Prosthetic Materials and Natural Teeth

Abstract:

To study the effects of different oral environment factors on the friction and wear properties between dental prosthetic materials and natural teeth, several comparing experiments were implemented by using a reciprocating friction and wear test machine containing an artificial saliva solution. Three kinds of factors including load, frequency and cycles were investigated on titanium alloy TC4 and zirconia ceramic. The experimental results showed that zirconia ceramic has a better wear resistance and a lower friction. The wear loss of titanium alloy TC4 was 10 times of that of zirconia ceramic under same conditions. A significant positive correlation between three factors and wear loss was also discovered.
