The disclosed content relates to a extraction guide device for root extraction, which allows the root to be extracted without damaging surrounding alveolar bones and gingival tissue during root extraction.

Unless otherwise indicated in this specification, the contents described in this identification item are not prior art to the claims of this application, and the description in this identification item is not admitted to be prior art.

Surgical extraction (tooth extraction) is one of the most common procedures performed in dentistry, when the absorption of the alveolar bone is remarkable and the fluctuation of the teeth is severe. Refers to a procedure in which a specific tooth is removed when a highly advanced, conservative or prosthetic treatment is not possible with only the root remaining, or when the root is destroyed by trauma.

In general, surgical extraction uses an extraction forcep, an elevator, or two at the same time. Even when a single root extends from one crown, the tip is thin or curved, or starts. If the site is divided into two, starting with a single root and proceeding to the root apex, it tends to break during the dislocation process.

As an example of a conventional root extraction device, in the Republic of Korea Patent Registration No. 10-1741071 (2017.05.29.announcement) in the dislocation mechanism for roots for extracting the roots remaining in the socket of the alveolar bone, between the root and the alveolar bone And having a hollow tube having an end portion with an adsorption hole formed thereon, a handle formed at the other end of the hollow tube to rotate the hollow tube, and suction means for providing air suction force to the adsorption hole, the end portion of the root It is formed in an arc shape having a curvature smaller than the curvature of the, the suction means is formed an expansion hole in communication with the adsorption hole in the handle, rotatably coupled to the expansion hole, connected to the adsorption hole and protrudes to the outside of the handle A nozzle body having a nozzle tube formed therein, a coupling plate screwed to the handle to prevent separation of the nozzle body, and the furnace Disclosed is a dislocation mechanism for a root, comprising an air pump connected to the bladder tube.

The dislocation mechanism for roots as described above is to remove the peripheral alveolar bone with a drill and remove the remaining root apical portion with a suction device when the distal end portion of the root remains in the extraction base, and is not only limited to extracting the apical portion of the root. Damage occurs in the surrounding alveolar bone, and further treatment proceeds, and there is a problem in that the teeth may be weakened.

As a way to solve this problem, the Republic of Korea Patent Registration No. 10-1838480 (announced on March 14, 2018) drills to form a root hole through the root, and one side and the other side are formed with threads, and due to the drill The extraction member for insertion into the formed root hole and the extraction aid member including the extraction member through-hole formed with a thread therein to be fastened to the extraction member, and a ratchet head part on one side to be fastened to the extraction aid member and the traction member A formed ratchet, a through-hole for passing through the extraction member is formed, and a collection guide member for seating the lower surface on the upper surface of the tooth, and a traction screw hole corresponding to the extraction member so as to be engaged with the extraction member on the inside. Disclosed is a root extraction kit including a traction member and a crowbar in which a mounting portion having an open shape is formed at one end to accommodate the traction member.

In the case of the root extraction kit as described above, after the extraction member is inserted into the root hole, the extraction guide member is seated on the upper surface of the tooth by passing the extraction member through the through-hole of the extraction guide member, and the upper surface of the extraction guide member. As the traction member is fastened to the outside by pulling the root to the outside by moving the traction member using either a ratchet or a crowbar while the traction member is fastened to the seat so that the surrounding alveolar bone and gingival tissue are not damaged. There is an advantage that can be removed.

On the other hand, in the case of the extraction guide member of the root extraction kit as described above, as the plurality of extraction member through-holes of the slit shape are spaced apart and the traction member is simply face-to-face on the upper surface, the traction member extends in all directions. There was a problem that the extraction procedure was rather cumbersome because it was difficult to rotate at a certain angle.

In addition, there was a problem in that the extraction member was bent due to extraction using a lever, so that it cannot be reused.

In addition, in the case of the extraction guide member of the root extraction kit as described above, when extracting the root adjacent to the root or dental defect located at both ends in the oral cavity, one side of the two sides cannot be supported by the adjacent teeth and thus on the teeth. There was a problem that the extraction procedure was somewhat cumbersome as the seating state of the was unstable.
