MICROMECHANICAL SEAL FOR DENTAL IMPLANT SYSTEMS

A micromechanical seal between a first body and a second body is co-axially threadably securable about a portion of the first body. The seal is created by the combination of an annular planar radial surface within the first body; a surface of rotation of the first body disposed radially inwardly of the annular plane surface and defining, within a radial plane of the body, an obtuse angle, relative to the planar radial surface, in a range of about 90.5 to about 92 degrees; and an annular convex radial surface within the second body, such surface fully complemental in radial dimension to the planar radial surface of the first body, the annular convex surface defining a radius of curvature in a range of about 2 to about 8 ten thousandths of an inch, in which upon complete axial threadable securement of the second body into the first body, a region of compression of material forming the convex surface of the second body occurs at a tangent point of the first and second radial surfaces and in which polar alignment between the first and second bodies, during their threadable securement is facilitated by the above defined obtuse angle.
