Description

[0001] Dental implant for dental operation [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dental implant mechanism, and more particularly, to a dental implant mechanism that can be applied immediately after a tooth is extracted from a patient and has excellent bonding force to the alveolar bone.

The dental implant procedure is completed by cutting the patient's gums (gums), inserting the implant post into the alveolar bone (gingival bone) and bonding an artificial tooth to the implant post.

The implant post can be roughly classified into two types depending on the procedure to be implanted when the implant is implanted.

That is, the implant post is a screw type implant post which is formed by a screw thread on an outer circumferential surface of the alveolar bone and is forcibly placed on the alveolar bone using a rotary tool, and a bistable type implant post which is forcibly placed on the alveolar bone using an impact tool .

In the conventional implant, it was necessary to wait for several months until the bone and the implant were stabilized after the implantation, and then the prosthesis for functional restoration had to be installed. Implants for rapid functional recovery should have good initial fixation, sufficiently disperse the masticatory force, and be able to fully cope with the masticatory force.

The embodiments of the present invention are intended to provide a dental implant mechanism that is easy to perform an implant procedure, but also has a strong bonding force to the alveolar bone after the operation.

An implant mechanism according to an aspect of the present invention includes at least two fixture bodies that are placed on an alveolar bone and extend to a lower end of an implant post and a joint body that connects the two fixture bodies and is placed on the alveolar bone with the fixture body And at least one diaphragm for enhancing a binding force with the alveolar bone.

Here, the diaphragm may be filled with a bone graft material that is implanted into the alveolar bone or the alveolar bone.

In addition, the diaphragm may be provided with a protrusion for enhancing a binding force between the alveolar bone and the bone graft material to be implanted in the alveolar bone.

Further, the implant post may be formed in a shape corresponding to the root of the teeth to be extracted.

At least a part of the implant post is formed to correspond to the root of the tooth to be extracted, and may be formed to be larger than the root of the tooth to be extracted.

At least three fixture bodies may be formed, and the diaphragm may be formed to connect the adjacent fixture bodies.

At least one of the fixture bodies may be formed in a plate shape.

At least one of the fixture bodies may be formed in a cylindrical shape.

In addition, a plurality of the fixture bodies may be formed in a columnar shape.

The lower end of the fixture body may be pointed downward.

In addition, a plurality of blades may be formed at random intervals on the outer circumferential surface of the fixture body.

The implant post may further include an abutment integrally formed with the implant post.

The implant post may further include an abutment detachably coupled to the implant post.

According to another aspect of the present invention, there is provided an implant mechanism including at least two fixture bodies that are placed in the alveolar bone and extend to the lower end of the implant post, an abutment connected to the implant post, and at least one of the at least two fixture bodies As shown in FIG.

Also, the coupling portion may be formed to be inserted into at least one of the at least two fixture bodies so that the bone graft material implanted into the alveolar bone penetrates into the interior.

The plurality of coupling portions may be formed on an outer surface of at least one of the at least two fixture bodies so that the coupling portions intersect with each other.

The coupling portion may protrude from at least one of the at least two fixture bodies toward the bone graft material to be implanted into the alveolar bone.

The embodiments of the present invention can be provided to form a shape that is as close as possible to teeth to be extracted by forming a plurality of fixture bodies, so that the coupling to the alveolar bone has an excellent effect.

In addition, the embodiments of the present invention have an effect that the placement of the implant post is facilitated by the provision of the diaphragm in the plurality of fixture bodies, and the bonding force with the alveolar bone is improved.

The fixture body has an irregular shape such as an insect's foot or a fishing needle, thereby improving initial and long-term stability. Also, as in the case of natural teeth, it is possible to manufacture the prosthesis so that the boundary line between the gums and the teeth and the transition line of the root and crown are similar to the natural teeth, thereby providing an improved aesthetic.

Hereinafter, embodiments of a dental implant mechanism according to the present invention will be described in detail with reference to the accompanying drawings.

Fig. 1 is a cross-sectional view showing a state in which an implant post of a dental implant mechanism according to a first embodiment of the present invention is placed, Fig. 2 is a front view of the implant in Fig. 1, 2 is a cross-sectional view taken along AA and BB lines, and Fig. 3C is a cross-sectional view according to another embodiment.

Referring to FIG. 1, a dental implant mechanism 300 according to an embodiment of the present invention may include an implant post 400 to be placed on an alveolar bone (B). The dental implant mechanism 300 may further include a crown connecting portion 20 formed at one end of the implant post 400. At this time, the implant post 400 and the crown connecting portion 20 may be integrally formed.

The implant post 400 may be connected to the crown tube 30 through the crown connection 20. Specifically, the crown tube 30 is connected to the abutment 50, and the abutment is connected to the crown connecting portion 20 so that the crown connecting portion 20 and the crown tube 30 can be connected.

At this time, the dental implant mechanism 300 can be variously classified according to the connection form of the crown tube 30 and the implant post 400 or the connection form of the crown connecting portion 20 and the abutment.

For example, the dental implant mechanism 300 may include a crown connection 20 and an integral dental implant mechanism in which the abutment is integrally formed. The dental implant mechanism 300 may include a crown connecting portion 20 and a removable dental implant mechanism connected to the abutment so as to be detachable from each other. At this time, the detachable dental implant mechanism has an internal type in which a part of the abutment is inserted into the crown connecting portion 20, and an external type (for example, a crown connecting portion 20 in which a part of the crown connecting portion 20 is inserted into the abutment) external).

Since the above-described methods of mounting the integral type and the separated type dental implant mechanism are similar to each other, the following description will be made in detail on a separate type dental implant mechanism. In particular, the external type and the internal type are similar to each other, and the following description will be focused on the external type.

Specifically, the implant post 400 includes a crown tube 30 coupled to the abutment for coupling the crown tube 30 to the female threaded portion 22 formed on the crown connecting portion 20 using the crown coupling bolt 35 Is one of the implant mechanisms to be placed in the alveolar bone (B).

The implant post 400 to be placed on the alveolar bone B must be firmly fixed to the alveolar bone B in the implant procedure and the gingiva G covering the alveolar bone B should be formed naturally.

The present invention proposes a dental implant mechanism that can assure a stable bonding force of the implant post 400 as much as possible in the above-described implant procedure and facilitate the placement of the implant post 400 in the alveolar bone B. In particular, the implant posts having two or more fixture bodies 410 and 412 as in the present invention can be collectively referred to as "multi-type ".

2, the dental implant mechanism according to the present invention includes an implant post 400 to be placed in the alveolar bone B, at least two fixtures 400 extending to the lower end of the implant post 400, At least one body (410, 412) is connected to the two fixture bodies (410, 412), and the alveolar bone (B) is placed together with the fixture bodies (410, 412) And a diaphragm (fixing film) 450.

In general, unlike a screw-type implant post, in which the implant post 400 having two or more fixture bodies 410 and 412 are combined by a single fixture body and rotated by the rotary tool to the alveolar bone, So as to be vertically bonded to the alveolar bone (B). Accordingly, the lower ends of the fixture bodies 410 and 412 and the diaphragm 450 can be sharpened or sharpened to facilitate the insertion into the alveolar bone B. In addition, the initial and long-term safety of the fixture body can be improved by forming irregularities like insect's legs on the fixture body.

Such an implant post 400 has an advantage that it can be used immediately after extraction of a tooth from a patient. In addition, since there is less space between the extraction and the implant body (fixture body) due to the extraction of the alveolar bone due to the extraction and the like, artificial bone grafting can be minimized. Therefore, the procedure can be performed with a minimum of invasiveness, and an economical effect may also occur.

3A, the diaphragm 450 is not formed on the upper part of the implant post 400 and the diaphragm 450 is inserted into the lower part of the fixture body 410, 412, Can be formed.

The diaphragm improves the binding force to the alveolar bone and can greatly improve the stability of the implant. The position of the diaphragm is not limited to being disposed at the center of the fixture bodies 410 and 412 as shown in FIG. 3B, but may be disposed at various positions as shown in FIG. 3C. This arrangement can be applied to a case where there are three or more fixture bodies to be described later.

FIG. 4 is a front view showing an implant post when three fixture bodies are formed as a dental implant mechanism according to a second embodiment of the present invention, FIG. 5 is a sectional view taken along line CC in FIG. 7 is a front view showing a dental implant mechanism according to a third embodiment of the present invention, and Fig. 8 is a sectional view of the diaphragm shown in Figs. 2 and 4, And Fig.

In particular, a through hole (not shown) may be formed in the diaphragm 450 to be placed together with the fixture bodies 410 and 412 in the alveolar bone B, as shown in FIG. 8, to improve the stability of the implant. This will be described in detail later.

Since the multi-axial implant post 400 functions as a fixture body of the extracted tooth placed in the tooth part to be extracted from the patient, it may be formed in advance in the same shape as the tooth to be extracted, It can be formed larger than the teeth to improve the bonding force with the alveolar bone (B). That is, since the tooth formed to be larger than the tooth to be extracted can be fixed more firmly than when it is placed on the alveolar bone (B).

In another embodiment 500 of the dental implant according to the present invention, at least three fixture bodies 520, 522 and 524 are formed and the diaphragm 550 is adjacent to the fixture bodies 520, 522, 524 are connected to each other.
