A method for producing dental moldings from a thermoplastic, whereina shaping model (7) of the desired dental molding is produced from wax, plastic or a similar fusible, combustible or otherwise residue-free removable material, the shaping model (7) is embedded in a heat-resistant molding compound (9), the model (7) having a connection to the outer side of the molding compound (9) directly or at least with a connecting element (8) of wax, plastic or a similar fusible, combustible or otherwise residue-free removable material, the molding compound (9) is cured and the model (7) and the optionally present at least one connecting element (8) are removed from the molding compound (9), preferably by the action of heat, to form a mold cavity (11) corresponding to the negative of the desired dental molding, the thermoplastic heated to processing temperature is introduced under pressure into the formed mold cavity (11) in the molding compound (9) through the connection to the outer side, and the thermoplastic forming the desired dental molding is released after solidification. The molding compound (9) has a temperature of at least 150° C in the area of the mold cavity (11) at the time of introduction of the thermoplastic. An apparatus for carrying out the method has a device for applying pressure to the plunger (14) for introducing the thermoplastic into the mold cavity (11) of the molding compound. |
