Abstract
The base for a dental prosthesis includes an outer body of biocompatible metallic material with a cavity in which an inner body of biocompatible metallic material with a seat for holding a prosthesis is disposed with the interposition of a layer of shock-absorbent material. An annular retaining element connected to the edge of the cavity in the outer body has a resiliently-deformable inner edge which engages a corresponding outer collar on the inner body so as to be resiliently preloaded thereby.

A base for a dental prosthesis for implantation in bone, including an outer body of rigid biocompatible metallic material having means for anchoring it to bony tissue and a cavity, an inner body of a rigid biocompatible metallic material having a seat for holding a prosthesis disposed in said cavity and a layer of resilient shock absorbent bonding material disposed between said outer body and said inner body;
- an annular retaining element being connected to an edge of the cavity in the outer body and having an inner edge;
- wherein the inner edge of the annular retaining element is in engagement with a corresponding outer collar on the inner body so as to be resiliently preloaded against the inner body.
