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.
