The present invention relates to a tooth implant for implanting a false tooth in the alveolar bone in dentistry instruments, and more particularly to an implant having functions of vertical self-drilling, horizontal self-drilling, self-cutting, self-condensing, and self-changing of direction, which increases the initial fixing force and ingression ability, has excellent correction capability to correct procedural errors, and minimizes the drilling operation heightening the probability of error or failure.
