title: [Experimental studies on the accuracy of replicas in the manufacture of crowns from composites].
abstract: Various replica models were studied in terms of surface-profile measurements and with scanning electron microscopy in the context of a continuous in vivo study of composite restoration. After taking an impression with a gum-elastic impression material, Araldit replicas, of all models tested, proved to be the most accurate.
