US Patent 10441385 Dental implant with interlocking and centering threads

A fastener for embedment in bone includes a chevron-shaped thread pattern having a first radial superior surface at an angle beta on a blank relative to a longitudinally extending axis of the fastener, a second radial superior surface at an angle alpha inboard to the first radial superior surface and relative to the longitudinally extending axis such that the two superior surfaces form a V-shape geometry. The fastener further includes a flank surface underlying the second radial superior surface at an angle gamma, the angle gamma defining an angle with the longitudinally extending axis that is 90°, a relief surface underlying the first radial superior surface such that the flank surface and the relief surface form a V-shape geometry, and a radially-outermost surface adjacent to the relief surface and defining a major diameter of the thread pattern, the radially-outermost surface being parallel to the longitudinally extending axis of the fastener.
