- Primary Outcome Measures
Name Time Method Antagonist surface wear after 36 months. The wear is documented by a two stage impression technique and by intraoral optical scanning. The conventionally obtained models are examined by SEM (scanning electron microscope) and white light profilometry in order to calculate volume and height loss. The digitally acquired models are virtually superimposed in order to determine the volume and the vertical loss, too.
- Secondary Outcome Measures
Name Time Method ongevity of full contour zirconia crowns evaluated by the means of clinical criteria (e. g. CDA-criteria = California Dental Association criteria)
