Abstract
A tooth extraction tool to sever through a periodontal ligament for atraumatic extraction of a tooth in humans is provided. The tool includes an elongated handle with two ends. The tool further includes a blade attached to one end of the elongated handle. The blade flexes to adapt to the shape of the periodontal ligament when the blade is vertically moved between the alveolar bone and the tooth to be extracted along selected tooth surfaces. The vertical movement of the blade relays an axial force to sever the periodontal ligament.
Claims26
A tooth extraction tool (100) configured to sever through a periodontal ligament (PDL) (11) for atraumatic extraction of a tooth (10), comprising:
- an elongated handle (101) with a first end (101a), and a second end (101b);
- and
- a blade (102) attached to the first end (101a) of the elongated handle (101), the blade (102) flexes to adapt to the shape of the periodontal ligament (PDL) when the blade (102) is vertically moved between alveolar bone (12) and the tooth (10) to be extracted along selected tooth surfaces, and wherein the vertical movement of the blade (102) relays an axial force to sever the PDL (11).
A tooth extraction tool (100), comprising:
- an elongated handle (101) with a first end (101a), and a second end (101b), wherein the first end (101a) of the handle (101) comprises a first connecting feature (101e);
- a blade (102) comprising a first end (102a) and a second end (102b), wherein the second end (102b) of the blade (102) comprises a second connecting feature (102d);
- wherein, the first connecting feature (101e) of the handle (101) and the second connecting feature (102d) of the blade (102) are connected using a fastener (103);
- and
- wherein, the blade (102) when vertically moved along selected tooth surfaces of a tooth 10 to be extracted, the blade (102) adapts to the shape of a periodontal ligament (PDL) 11 and relays an axial force to sever the PDL (11).
A method of tooth extraction, the method comprising:
- gripping a handle (101) of a tooth extraction tool (100);
- vertically moving a blade (102) of the tooth extraction tool (100) along selected tooth surfaces of a tooth (10) to be extracted between the tooth (10) and an alveolar bone (12), wherein the blade (102) adapts to the shape of a periodontal ligament (PDL) (11) during the vertical movement;
- and
- relaying an axial force to sever the PDL (11) by the blade (102) severing through the PDL (11).
