Abstract:
Disclosed is a "condensing screw for an implant procedure." The "condensing screw for an implant procedure" according to the present invention comprises: a screw body (110), which is inserted into an implant planting hole formed by an initial drilling process, enlarges the implant planting hole to a size large enough to insert an implant fixture, and forms osseodensification regions on the side surfaces and the inside of the implant planting hole; and a shank (120) which extends upward from the screw body (110), is coupled to a driving unit, and transmits the torque of the driving unit to the screw body (110). The "condensing screw for an implant procedure" according to the present invention can be used to simultaneously enlarge the implant planting hole and perform an osseodensification process, and can be used for maxillary sinus augmentation. Also, a rake angle of 0 to 90 in the positive direction is formed upon rotation in the opposite direction, thus providing excellent cutting performance, and making it possible to drill the implant planting hole without a separate initial drilling process and quickly enlarge the implant planting hole.
