Abstract: Disclosed herein an implant system for a denture. The denture implant system includes: an abutment and a screw configured to connect the abutment to a denture. The abutment comprises: an apex portion configured to face the denture and have linear edges that are parallel at least in an intermediate area, a thread hole provided in one end area of the apex portion and configured to accommodate the screw, and a fixture hole which is spaced apart from the thread hole and is formed toward a fixture engagement portion under the apex portion.

Abstract: An implant set device for sinus membrane elevation is provided. Herein, implant set device for sinus membrane elevation includes an initial drill group for an alveolar bone including a multiplicity of initial drills for an alveolar bone, a dilatation drill group for an alveolar bone including a multiplicity of dilatation drills for an alveolar bone, a sinus drill group including a multiplicity of sinus drills, a final drill group including first final drills, and a receiver having a drill region where the drills can be received in a first direction with the effective length increasing in each drill group and the drills can be received in a second direction in which drills of each drill group belonging to the drill group for surgery are arranged in a surgical procedure of the sinus membrane elevation.

Abstract: Provided herein is a drill for a dental implant. The drill for a dental implant includes a coupling part connected to a hand piece configured to provide a rotational force, a body part disposed below the coupling part and configured to transmit the rotational force downward, a cutting part including a plurality of cutting blades and a void section, the cutting blades being disposed below the body part in order to cut an alveolar bone and form a hole therein and being spaced apart at a predetermined angle in a rotational direction, and the void section being surrounded by the cutting blades along at least a portion of an inner circumference of the cutting blades, and a coolant passage configured to communicate with the void section by passing through the coupling part and the body part and configured to, while the alveolar bone is being cut, supply coolant to the void section so that the coolant is introduced to the cutting blades.

Abstract: Provided is an implant fixture. The fixture includes a first area portion including a plurality of first screw portions configured to correspond to a cortical bone during implantation in a bone tissue and have a first ridge portion and a first bottom portion which are formed to have a spiral shape and alternately disposed in a direction of a central axis, and a plurality of non-screw portions provided between adjacent first screw portions and including a continuous surface having a smaller radius at a terminal end of a first screw portion of one side than a radius of the first bottom portion with respect to the central axis, wherein the radius gradually increases toward a beginning end of a first screw portion of another side, and a second area portion positioned below the first area portion and configured to correspond to a cancellous bone of the bone tissue during the implantation in the bone tissue.
