Abstract: A material is proposed as an essential abrasive component for cleaning agents in cleaning products for delicate surfaces which is essentially composed of platelets. These platelets are preferably shaped without sharp points, i.e. their circumference is similar to a polygon whose corners do not show angles that are in the majority smaller than 30° and greater than 330°. Glass flakes are for example such a material. The abrasive component of the invention may for example be used for the manufacture of toothpastes and prophylaxis pastes that are efficient but nevertheless not harmful to teeth.

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.

Abstract: The dental device comprises an abrasive disk having a hub made of synthetic material and a spindle with a collet, the opening of the hub having an inner bead and the collet a rotation lock and an axial lock for receiving said bead in the hub opening, the greatest diameter of the spindle with its rotation lock being greater than the diameter of the hub opening with its bead. This construction allows, on one hand, an easier mounting of the abrasive disk on the spindle, and, on the other hand, a high torque transmission.

Abstract: The method for joining a metal foil with a synthetic material foil comprises unwinding both materials from a supply roll each, and subjecting the synthetics foil, prior to the application of an adhesive, to a corona discharge on a narrow border region. The metal foil and the synthetic material foil are then pressed together and irradiated by ultraviolet radiation causing polymerization of the adhesive. The composite foil material thus obtained is transferred to a further processing station. There the dental matrix can be punched out of such a composite sheet material, having a high tensile strength, whose metal portion can easily be inserted between two adjacent teeth whereas the transparent synthetic material part allows light curing of the dental filling material.
