Tribological wear of some prosthetic materials in contact with dental ceramic (in vitro investigation)

Koczorowski R.

Acta of Bioengineering and Biomechanics

1999

Vol. 1, nr 2

13-17

The present study aimed at a comparative evaluation of tribological wear of various combined prosthetic materials used in the restoration of occlusal surfaces of fixed partial dentures. The tribologic station ST-3 was used to examine the resistance to wear of 4 commonly used materials in contact with the surface of glazed and unglazed porcelain in two different environments. Moreover, the impact of these materials on the wear of porcelain was evaluated. The finding highlighted the importance of the total wear of two contacting surfaces.
