Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for holding an artificial tooth root to be embedded in a jawbone for fixing a denture.

[0002]

Prior Art and Problems to be Solved by the Invention FIG.
FIG. 6 is a cross-sectional view showing a conventional artificial tooth root storage container. In the artificial dental root burying operation, the artificial dental root to be embedded is transported and stored from the time of production to the burying operation in a hermetically sealed container including a lid 5 and a container 4 as shown in FIG. Implantation of the artificial tooth root 7 is performed by opening the lid 5 of the container immediately before the operation, pinching the artificial tooth root 7 therein with tweezers or the like, and taking it out from the container 4, temporarily placing it in a bat or the like, and pinching it with tweezers or the like when burying it in the oral cavity. This was done by setting it in the hole drilled in the jawbone of

However, it takes a lot of time to take out the artificial tooth root 7 from the container 4 with tweezers or the like and set it in the hole, and since it is temporarily put in a bat or the like, there is a sanitary problem.

In view of the above problems, it is an object of the present invention to provide an artificial root holding device which can be easily set in a hole drilled in the jawbone in the oral cavity and can be operated hygienically.

[0005]

In order to achieve the above-mentioned object, the present invention comprises a holding member holding an artificial tooth root, and an integral or separate body from the holding member, which is displaced by pushing with a finger. It is characterized in that it comprises a pushing means for pushing out the artificial tooth root from the holding member, and a container for detachably mounting the holding member.

[0006]

The artificial tooth root retainer of the present invention has the above-mentioned structure, and removes the artificial tooth root together with the holding member from the container, and pushes the artificial tooth root from the holding member to the jawbone in the oral cavity via the pushing means. Set directly by extruding into the drilled holes.

1 (A) is a sectional view showing an embodiment of an artificial tooth root holder according to the present invention, and FIG. 1 (B) is a perspective view showing a state taken out from a container. As shown in FIGS. 1 (A) and 1 (B), an artificial tooth root holder 1 holds a holding member 3 for an artificial tooth root 7, a push pin 2 for pushing out the artificial tooth root 7, and the holding member 3 in a detachable manner. Storage container 4 and storage container 4
And a lid 5 fitted to.

The holding member 3 is made of a cylindrical soft resin or rubber, has an opening 3b on the lower surface, and has a hole 3a smaller than the opening 3b at the center of the upper flange 3c. . The push-out pin 2 is made of a hard resin or a metal, and has a disk-shaped collar portion 2b fitted in the holding member 3 so as to be vertically movable, and a rod portion protruding from the center of the collar portion 2b to the upper surface. 2a, and the rod portion 2a is vertically movably inserted into the hole 3a of the holding member 3. Artificial tooth root 7
Is fitted into the opening 3b of the holding member 3 by utilizing its elasticity, and is brought into a fitted state in which the pushing pin 2 has a strength capable of being pushed out. The accommodating container 4 is made of resin and has a bottomed tubular shape, and is detachably fitted to the lower portion of the holding member 3 below the flange portion 3c. The storage container 4 is preferably made of transparent resin or glass so that the artificial dental root 7 inside can be seen. The lid 5 is made of resin or metal and is detachably fitted and attached to the storage container 4.

The artificial tooth root 7 of the present embodiment is of a type that does not require burying work by a driver, and is a sealing material for preventing the gingiva 8 and body fluid from entering the central screw portion 7a for attaching the crown. (In this example, an example in which this seal material is a screw type seal screw 6 is shown) is attached to the holding member 3. The artificial tooth root 7 is transported and stored until the implantation operation in the above state.

FIG. 1C is a cross-sectional view of the jawbone portion showing a treatment state in which an artificial tooth root is embedded. As shown in FIG. 1C, in the artificial root implant operation, the lid 5 is opened immediately before the operation, and the collar part 3c of the holding member 3 is manually pinched while the artificial root 7 is attached to the holding member 3 and the container 4 is held. The rod portion 2a of the push-out pin 2 protruding from the hole 3a of the holding member 3 is pushed from above while being set in the hole 10 bored in the jawbone 9 in the oral cavity, so that the collar portion 2b of the push-out pin 2 is By pushing out the artificial tooth root 7 from the holding member 3, it can be embedded in the hole 10 provided in the jawbone 9.

As described above, since the holding member 3 can be directly grasped by hand without using an instrument such as tweezers, the artificial tooth root 7 can be embedded accurately and quickly. In addition, it is hygienic because the lid 5 is removed and the work is performed immediately after removing the lid 5.

FIG. 2 (A) is a sectional view showing an artificial tooth root holder 1A of another embodiment, and FIG. 2 (B) is removed from a container,
It is sectional drawing of a jawbone part which shows the state which has embedded the artificial tooth root. As shown in FIG. 2 (A), this embodiment is different from the above-described embodiment in that the holes on the upper surface of the holding member 3 are eliminated and the wall thickness of the upper surface portion 3d is reduced except for the extrusion pin 2. It is used as a means for pushing out the artificial tooth root 7. In the case of the present example, as shown in FIG. 2 (B), the holding member 3 is pinched by hand and taken out from the container, and the hole 10 is formed in the jawbone 9 in the oral cavity.
And pressing the thin portion 3d on the upper surface of the holding member 3 allows the artificial tooth root 7 to be pushed out of the holding member 3 and embedded in the hole 10, and the same effect as the above-described embodiment can be obtained. Be done. According to this embodiment, the lid 5 can be eliminated by closely fitting the container 4 and the holding member 3.

[0013]

According to the present invention, it is possible to easily, swiftly and hygienically embed an artificial tooth root in a hole drilled in the jawbone in the oral cavity.
