Document Type and Number:
WIPO Patent Application WO/2017/099282
Kind Code:
A1
Abstract:
The present invention relates to a dental prosthesis removing member. The present invention comprises: a head portion (110), which is coupled to a manual operation handle mechanism (10), and which comprises three separate pieces; a rotation compressing portion (120) formed to absorb noise resulting from metallic coupling, to buffer impact forces resulting from collision of a metallic coupling body, and to withstand pressurizing forces occurring when the manual operation handle mechanism (10) is pressurized downwards while being rotated; a screw portion (130) formed such that the same can form screw coupling with the prosthesis (20), the pitch of the thread of the screw portion (130) being formed in conformity with the thickness of the prosthesis; and a bottom surface portion (140) formed to be flat or round on a part that abuts the surface of a tooth. The present invention is characterized in that the length (h4) between the uppermost end of the head portion and the bottommost end of the bottom surface portion lies in the range of 12mm to 30mm; the length (h1) of the head portion lies in the range of 3mm to 8mm; the length (h2) of the screw portion lies in the range of 4mm to 20mm; and the length of the diameter of the outer diameter of the rotation compressing portion (120) lies in the range of 4mm to 8mm. Use of the present invention makes it possible to remove a prosthesis from the outer surface of a tooth in a simple and convenient manner.
