Retention die for use in dental implant system for retaining implant in upper or lower jaw, has retainer element held in retainer, where recess is formed at die inner surface such that retainer element is evaded into recess under stress

摘要

The die (22) has a retainer element held in a retainer for fixing a removable artificial denture at an implant (12), where the retainer element is made of resilient material such as polyoxymethylene. A recess is formed at an inner surface of the die such that the retainer element is evaded into the recess under stress. The recess is formed as an annular groove provided with groove edges, where each groove edge is connected with a supporting surface for supporting the retainer element in the retainer, where the die is anchorable such as polymerizable, in prosthesis.
