Abstract
Textured surface having micro recesses such that the outer surface overhangs the micro recesses.

A prosthetic device comprising:
- a selected repeatable pattern having
- a surface defining a cavity having a geometry characterized by at least one complex ellipsoid, and
- an undercut face projecting over a portion of the cavity.
A prosthetic device comprising:
- a plurality of cavities recessed into the prosthetic device;
- a plurality of curved concave surfaces having a complex ellipsoid shape, each of the plurality of concave surfaces at least partially defining a bottom of one of the plurality of cavities;
- the plurality of curved concave surfaces further defining a plurality of projections extending from the bottom of the cavities to form an undercut surface.
- wherein the plurality of cavities and the plurality of projections are arranged in a selected repeatable pattern.
