The present invention comprises: an insertion part which is inserted into a hole previously formed in a prosthesis a screw part which is formed to extend from an upper part of the insertion part and has a screw thread formed on an outer circumferential surface thereof, wherein a root of the screw thread is formed to have a diameter between a hole diameter and a sum of the hole diameter plus 0.3 mm, both inclusive, so that the screw part is screw-coupled to the prosthesis by rotating a coupling part formed on an upper part of the screw part and coupled to a rotation member of a rotation tool in such a way as to provide a rotational force to the screw part a body part formed between the screw part and the coupling part and a coupling hole formed to extend through the body part such that a safety string for preventing the escape of the prosthesis removing apparatus during prosthesis removal work is inserted into the coupling hole, wherein a discharging groove is formed to discharge dust produced when the screw part and the prosthesis are coupled. Therefore, the prosthesis removing apparatus can simply and conveniently remove a prosthesis to provide convenience for a user and can prevent the teeth and the gingiva from being impacted during removal of a prosthesis to eliminate the avoidance of use by patients.La présente invention comprend : une partie dinsertion, insérée dans un trou formé au préalable dans la prothèse une vis, formée de façon à sétendre à partir de la partie supérieure de la partie dinsertion, et dont la surface de la circonférence externe est fileté la racine du filetage est formée de façon à avoir un diamètre situé entre le diamètre du trou et la somme du diamètre de trou plus 0,3 mm, de sorte que la vis soit visé à la prothèse une vis, formée sur la partie supérieure de la vis est couplée à lélément de rotation dun outil de rotation de manière à fournir une force de rotation à la vis le corps formée entre la vis et la partie de couplage et un trou d
