1. An implant device for humans or mammals comprises:
- a solid body structure having an exposed surface;
one or more selected portions of the exposed surface having a porosity created by bone formation enhancing repeatable geometric 3-dimensional pattern duplicating or replicating the cancellous morphology of under-modelled pre-cancellous bone mimicking a marine or sea mammal bone structure wherein the repeatable geometric 3-dimensional pattern is repeatably placed on portions of the exposed surface to create a substantially continuous network having voids having a medium width of 500 to 800 microns formed as a trabecular structure which enhances bone formation, the voids of the substantially continuous network extend to a depth of 150 microns or less from the one or more portions of the exposed selected surface having the 3-dimensional pattern providing the depth of the 3-dimensional pattern, the depth being the distance the pattern penetrates into the body structure to produce the repeatable 3-dimensional pattern for enhancing bone formation of about 150 microns or less.

Abstract
An implant device for humans or mammals has a body structure having an exposed surface and one or more selected portions of the exposed surface having a bone formation enhancing 3-dimensional pattern. The exposed surface can be on exterior portions of the body structure or internal portions of the body structure or both. The one or more selected portions of the exposed portions having the bone formation enhancing 3-dimensional patterns are in the external exposed surfaces or in the internal exposed surfaces or both internal and external exposed surfaces.
