Method for deep drawing sheets onto individual stumps in dentistry

摘要

The stumps are held in a granular bed and a heated sheet is pulled onto the stumps while a vacuum is applied below them. The stumps are surrounded by a funnel whose upper edge is provided with a sealing lip. A receptacle (6) for the granulate has a funnel (4) whose upper edge has a sealing lip, and vacuum-generating device and a holder unit (2) for the foil. The granular filling comprises granulate with a diameter of between 0.2 and 0.5 mm. The sealing lip is in the form of a rubber O-ring.
