Tribological Comparative Study on Two Composite Materials for Restorative Dental Applications

In this study we determine the wear coefficient and the volume of spent material were tested two types of composite materials used in restorative dentistry practice. Based on all tests performed, there are observed differences between the coefficients of abrasive wear for the two types of composites. The volume of material moved (used) increased proportionally with load increasing, but it is independent, both parameters are justified to be used in the normalization of measurable wear values
