Abstract: In the method for the manufacture of dental tools for the treatment of surfaces, a rubber core serving as a carrier layer is first applied by injection molding onto the spindle of the tool, and the abrasive layer comprising the abrasive grains is subsequently applied to the carrier layer. In another method for the manufacture of dental tools for different treatments of surfaces, more particularly for coarse grinding, finishing, and polishing, rubber-elastic masses of different degrees of hardness are used for the abrasive parts of the tools according to the intended treatment, and abrasive grains of the same size are embedded in the rubber-elastic mass of these parts.
