Abstract
A dental implant includes a rigid body having axially symmetric and radially circumferential spiral pitch surfaces, in a range of about 22 to about 28 pitch surfaces per axial inch, an upper concave bevel surface above each pitch surface, which is longer than a lower bevel surface beneath each pitch surface, and an intersection of each plane of each pitch surface, and each plane of each lower bevel surface defining a total included angle in a range of about 90 to about 130 degrees, the rigid body having minor thread diameters at intersections, between pitch surfaces, of the upper and lower bevel surfaces, the pitch surfaces and the minor thread diameters defining, at any axial radius of the rigid body, a ratio of thread pitch to thread depth in a range of about 1.25:1 to about 1.40:1. Each of the lower bevel surfaces define a total included angle in a range of about 20 to about 30 degrees relative to any given axial radius of the implant at a minor thread diameter.
