Abstract: Dental coating compositions that have one or more of excellent properties including plaque resistance, microbial plaque resistance, strong adhesion, excellent hardness, high wear resistance, and high color resistance are provided. Dental appliance or natural tooth covered by the dental coating compositions, and production methods of the dental coating compositions are also provided. The coating compositions include one or more of a trifunctional or higher multifunctional (meth)acrylate monomer, an inorganic filler, a photoinitiator, and an organic solvent. The coating compositions are substantially free from antibacterial chemical additives.

Abstract: The invention relates to a method for the production of blocks of material of a polymerized dental composite material as well as to the blocks of material obtainable according to the method, in which (i) a polymerisable dental composite material is transferred into a pressure-resistant casting mould (100), (ii) a pressure in the range of 10 to 500 MPa is applied to the polymerisable dental composite material in the pressure-resistant casting mould, and (iii) at least a part of the casting mould and/or the polymerisable material is heated in a defined manner to a temperature of 90 to 150° C.

Abstract: In a manufacturing method for a tank with an opening and with a device for damping a splashing movement, porous filler bodies which fit through the opening are introduced as a damping device into the tank until the tank is completely filled with them. Accordingly, a tank with an opening and a device for damping a splashing movement is characterized in that the device for damping comprises porous filler bodies which fit through the opening.
