PROBLEM TO BE SOLVED: To provide a apparatus of collecting dental cut dust for recycling the cut dust of a prosthesis as the resource of precious metals without causing a problem in the washing work of the inside of an oral cavity by efficiently collecting the cut dust of the prosthesis without reducing the suction force of a vacuum apparatus. SOLUTION: The collecting apparatus 1 of the dental cut dust is provided with: a casing 15 which has the shape of a bottomed cylinder and is arranged in a longitudinal direction; an ejection port 16 which communicates with the upper part of this casing 15 and can be connected with the suction part 10 of the casing 15; a flow-in port 17 which communicates with the side part of the casing 15 and can be connected with a suction pipe 12 to be inserted to the inside of the oral cavity; a deflection member 19 which generates a swirl R by rotating a gas-liquid fluid mixture containing the cut dust 18 of the prosthesis having flown in through this flow-in port 17 along the inner circumferential surface of the casing 15; a partition member 20 provided in the inside of the casing 15 so as to permit the cut dust 18 to fall and to regulate upward scattering thereof; and an opening and closing member 23 for taking out the cut dust 18 accumulated at the bottom of the casing 15 to the outside.
