| abstract |
Prosthetic element comprising a cap (11) made from metallic material, which has an acetabular clamping surface (11a) inside, said cap (11) having an internal wall (16) lining the clamping surface (11a) and an external part consisting of a grid (12) with cells that make up a plurality of cavities (18) arranged three-dimensionally, open and intercommunicated, connected to each other, said grid (12) being solid with the part facing outwards of the inner wall (16), wherein the inner wall (16) has been manufactured from a compact material and said reticle (12) is substantially a single body with said inner wall (16), where at least a part is formed of the grid (12), without interruption in continuity also with respect to the inner wall (16) and using the EBM technique (melted by electronic beam) or the DMSLS at the same time with the inner wall (16) (yes direct laser metal), by one or more models of a plurality of geometric meshes (13) that are repeated in space by all or part of the body of the prosthetic element, which have a cellular geometry with open and adjacent elementary cells, to define a plurality of polygons (413) with a spatial development that delimits the cavities (18), so that the reticle (12) is capable of promoting bone integration. |
