ABSTRACT:
The adhesion of dental restorative materials, more particularly of composite materials containing an organic binder, to dental instruments can be reduced, essentially independently of the material of which the dental instrument is made, by providing the working surfaces with impressions. These impressions result in a reduction of the contact surface of the composite material on the working surface and thus in a reduction of the component of the adhesion which is due to physical attraction, e.g. to the van der Waals force. If the impressions are sufficiently small, a penetration of the composite material into the impressions is prevented by the high viscosity of the latter alone. If additionally the impressions are capable of being sealed by the tooth replacement material in contact therewith, an air cushion forms in the impressions which additionally counteracts a penetration of the tooth replacement material.
