Patent ID: 7980852

Claim:
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, and Removing 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 ).
