In this study, an in vitro wear behaviour of dental ceramic porcelain veneers was investigated. The ceramic veneers were fabricated on NiCrMo substrate through glazing method. Surface morphology of the veneers was characterized by scanning electron microscopy (SEM). The wear tests were conducted with the porcelain veneers at different loads under in vitro conditions through a pin-on-plate configuration against a human tooth counterbody. The worn surfaces of the porcelain veneers and human tooth counter material were examined by optical microscope. Porcelain veneer samples exhibit higher wear resistance and lower dynamic friction coefficient and wear rate do not change significantly at a given distance up to 100 N of applied load.
