Patent ID: 7556500

Claim:
A prosthetic device for implanting in bone comprising: a shaft said shaft having a first end and a second end; said first end having a mount for a dental device to be implanted; said second end being attached to a base; said base being substantially orthogonal to said shaft in at least two non-parallel directions, said base being substantially planar; at least one of a top surface or a bottom surface of said base having at least one apex and at least two valleys, said valleys being adjacent said apex, said apex and said valleys defining a macrostructure dimension, said macrostructure dimension being greater than the size of an osteon at a site of implantation; at least one of said surfaces having a surface including canals, said canals defining a microstructure dimension, said microstructure dimension being less than the size of an osteon at a site of implantation; and said valleys being at a marginal zone; said marginal zone being substantially along a portion of a periphery of said base; and said marginal zone having a radial width varying along said periphery of said base.
