•Against a hard antagonist, glass-ceramics exhibit moderate wear but extensive subsurface fracture.•Resin composites show large wear craters with the absence of subsurface damage.•The polymer-infiltrated reinforced-glass material displays large wear craters and severe subsurface damage.•Under extrem...
