Reciprocating wear test of dental composites against human teeth and glass

Abstract

The complexity of the contact in the mouth leads to an interplay of sliding wear, abrasion and fatigue, independently of the surfaces in contact, which involve either tooth-to-tooth or tooth-to-restoration. Since this is a complex problem and in vivo tests are expensive, much time consuming and the generalization of the attained results very complex, in vitro simulations are the usual research approach.
