Abstract

This method increases the precision of the components in an impression system for dental prosthesis of the type permanently anchored in the jaw by at least one securing elements implanted in the jawbone. Each of the securing elements is provided with a distance member whose upper part protrudes above the palatal arch and on which the finished dental bridge/dental prosthesis is then anchored via a so-called gold cylinder. The system includes impression components in the form of impression tops and distance dummies with continuous guide holes and stop members for a guide pin which, during fixing of the components, is guided through the respective guide hole and engages with the stop members of the respective impression component. That part of the guide pin which interacts with the stop members of the guide holes of the respective impression component has a conical stop surface, while the stop members form plane surfaces and guide edges. By such a design of the guide pin, the components are centered and the precision is improved in existing impression systems.
