Dental drill and drilling method for embedding a dental implant using the dental drill

摘要

To provide a dental drill and a drilling method for embedding a dental implant using the dental drill without necrosis of the jawbone due to frictional heat.SOLUTION: This drill has two cutting edges formed symmetrically with respect to the rotation axis, thinning is applied to the distal end portion, and when the cutting edge is viewed from the tip side of the drill, from the chisel edge to the outer peripheral side of the drill And a main cutting edge extending from an end portion of the thinning cutting edge to an outer circumferential end of the drill. When the thinning surface formed by the thinning cutting edge is viewed from the front side of the drill , A first dental drill which is formed in a substantially parabolic shape inclined with respect to the drill axis center direction, a diameter of the tip portion is smaller than a diameter of the drill and an inclined portion is provided, and the clearance angle is formed on the outer periphery of the inclined portion And the outer circumferential grooves are provided on both sides of the two cutting edges to be second and third dental drills having a drill diameter larger than that of the first dental drill.(FIG.
