The invention relates to a method for producing a dental mold on the basis of a thermoplastic film (4), and to an impression tray (1) for producing such a dental mold (2). The impression tray (1) is charged with a kneadable, malleable material (3) on which the thermoplastic film (4) that can be formed to a dental mold (2) is located. The softening temperature of the thermoplastic film (4) ranges between approximately 40 DEG C and approximately 80 DEG C.

The invention claimed is: 1. Method for producing a dental mold, comprising the following steps:Charging a rigid impression tray (1), which is solid at temperatures below 140° C., with a kneadable material (3), which is plastically deformable at least at temperatures between 20° C. and 80° C., and a thermoplastic film (4), such that said thermoplastic film (4) is horseshoe-shaped and has a U-shaped cross-section that is fitted to a contour of the impression tray and is disposed on said kneadable material (3), wherein the materials of the kneadable material and the thermoplastic film (4) are selected in such a manner that they do not combine with one another at the processing temperature,Subsequently heating the thermoplastic film (4) disposed on said kneadable material (3) to a temperature that lies below 80° C. and above the softening temperature of the thermoplastic film (4),Applying into a patient's mouth the heated thermoplastic film (4) disposed on said kneadable material (3) in the impression tray (1),Placing the thermoplastic film (4) against at least one tooth, forming a dental mold (2), for a time span until the thermoplastic film (4) has cooled to a temperature below its softening temperature, andRemoving the impression tray (1), the kneadable material (3), and the dental mold (2) formed from the thermoplastic film (4) together from the patient's mouth and removing the dental mold (2) afterwards from the kneadable material (3) and the impression tray (1).
