Abstract: A dental drill bit for creating a particularly shaped osteotomy in a human jawbone includes: a mounting shank and cutting head. The cutting head includes: four blades protruding away from an axis of the drill bit, each blade having a thickness and being positioned 90 degrees to each adjacent blade to form a cruciform-shaped cross-section, with two pairs of the blades each positioned 180 degrees apart. Each of the pair of blades positioned 180 degrees apart are offset laterally a distance about equal to the blade thickness, and each blade has a shaped periphery that includes: a first radiused periphery; and a second radiused periphery. The first radiused periphery is shaped to form a hemisphere frustum-shaped socket portion when rotated about the axis of the drill bit, and the second radiused periphery is shaped to form a bullet shaped socket portion when rotated about the axis of the drill bit.

Abstract: A first dental drill bit for creating a particularly shaped osteotomy in human jawbones includes: a mounting shank and cutting head. The cutting head includes: four blades protruding from an axis of the bit, each blade having a thickness and being positioned 90 degrees to each adjacent blade to form a cruciform-shaped cross-section. Each of the pair of blades are positioned 90 degrees apart, and the blades of each pair are offset laterally a distance about equal to one-half of the blade thickness. Each blade has a shaped periphery that includes: a first radiused periphery; and a second radiused periphery. The first radiused periphery is shaped to form a spherical frustum-shaped socket portion when rotated about the axis of the drill bit, and includes embedded diamond particles. The second radiused periphery is shaped to form a bullet shaped socket portion when rotated about the axis of the drill bit.

Abstract: A dental drill bit is configured to drill a particularly shaped opening in a human jawbone. The dental drill bit includes first, second, and third portions. The first portion includes a bullet-shaped contour formed by revolving a curve about an axis creating an apex and a bottom, and is so shaped to correspond to a bullet-shaped portion of a dental implant. The second portion includes a hemisphere frustum formed coaxial with the axis of the bullet-shaped contour, and extends from the bottom of the bullet-shaped contour, and corresponds to a portion of an abutment that is supported by the implant. The first and second portions may also each include flutes for cutting/drilling into bone. The third portion includes a shaft that extends from a bottom of the hemisphere frustum and is formed co-axial with the axis of the bullet-shaped contour, and is configured to be secured within a dental drill.
