Disclosed is a drill tool for lifting a sinus. The drill tool for lifting a sinus of the present invention lifts a sinus membrane positioned inside an alveolar bone after the drilling of the alveolar bone for implanting an implant. The drill tool of the present invention includes a drill for drilling the alveolar bone, wherein the drill includes a drilling body having one end with a cutter for drilling the alveolar bone and the other end with a through hole, and a drilling rod which is coupled to the drilling body toward the through hole of the drilling body such that the drilling rod gets closer to and far from said one end of the drilling body, and adjusts the drilled depth of the alveolar bone during drilling. According to the present invention, processes for drilling an alveolar bone for an implant operation are carried out sequentially by a plurality of drills to form firm holes in the alveolar bone, and a sinus membrane is lifted in a stable manner to prevent damage to the sinus membrane, thus improving the reliability of implant operation. |
