A SYSTEM FOR TAKING IMPRESSIONS FOR THE PREPARATION OF IMPLANT SUPPORTED DENTAL PROSTHESIS AND MEANS FOR CARRYING OUT SYSTEM

摘要

A system for taking impressions aimed at the preparation of implant supported dental prothesis and means for carrying out the system, wherein a preliminary pattern is used to conform a metallic structure (8) defining as many formations (8.1) as pillars (11) existing in the mouth of the patient. Each formation (8.1) determines an independent compartment and on one of said formations (8.1) a transfer upper portion or end cap (9) is mounted in the laboratory; the metallic structure (8) together with the transfer upper portion or end cap (9) is subsequently transferred to the mouth of the patient. To obtain the metallic structure, calcinable material preforms are used as well as positioning elements each comprising a metallic core and an elastic enclosure.
