Description

Implant {Implant}

The present invention relates to an implant, and more particularly to an implant that can be easily mounted and repaired by improving the structure of the abutment.

In general, the teeth are gradually eliminated in order of adaptation to the growth of jaw bone and permanent teeth are generated at the position of the dropped teeth.

However, since the permanent teeth are not regenerated once dropped out, medical procedures have been developed to provide a permanent substitute for permanent teeth due to deterioration of the permanent teeth or accidents.

As the procedure, a bridge procedure for processing teeth close to the dropped permanent teeth and a partial or total prosthesis procedure performed when no adjacent teeth supporting the bridge are present are known.

However, since the bridge treatment processes the teeth close to the dropped tooth, the healthy tooth is damaged, and partial prosthetics and the entire prosthesis are inconvenient to be attached to or detached from the oral cavity, resulting in the formation of foreign bodies and damage to the healthy teeth connected to the prosthesis. There is a problem such as that, recently implantation is being used.

These implants originally meant a substitute to recover when the human tissue was lost, but in the dentist refers to the implantation of artificial teeth.

In the case of ordinary prosthetics or dentures, over time

Although the bone is damaged, the implant does not damage the surrounding dental tissue, and it has the same function and shape as natural teeth but does not produce tooth decay, which can be used semi-permanently, but there is no sense or movement performed by natural teeth. There are many problems, and they have to undergo constant maintenance, maintenance and repair.

In the case of performing such an implant, as described in Patent Registration No. 10-691213 (name: resin cap for implant construction) shown in FIG. 1, a clinical examination is performed first and then a fixture (fixture) in the alveolar bone is performed. ; 1) is implanted, the procedure to connect the abutment (3) to the fixture (1) is performed, and the temporary artificial teeth for aesthetics are connected. And wait several months until the alveolar bone and fixture is combined to produce a prosthesis (7).

In order to manufacture the prosthesis, it is necessary to grasp the exact position and arrangement of the variously constructed implants according to the structure of the jaw bone and the arrangement of the teeth. To connect the coping and get the impression.

The impression thus obtained is sent to a dental laboratory, and the dental laboratory determines the abutment based on the impression and to determine the abutment to produce the prosthesis accordingly.

The prosthesis produced at the dental laboratory is sent to the dentist and the dentist connects the abutment to the fixture embedded in the patient's mouth in accordance with the shape of the proximal and opposing teeth to fix the prosthesis.

When working on the impression oral model, the milling process is performed to adjust the parallel direction, and the deformed form by the milling process is transferred to the patient's mouth. It is very difficult to place the abutment in the correct position in the process.

In this situation, the abutment is loosened and tightened to adjust the position of the abutment while the patient's mouth is open, causing inconvenience to the patient, and there is a high possibility of poor operation due to a mismatch between the prosthesis and the abutment. .

Moreover, fixtures placed in the upper and lower jaw should be parallel to the insertion path of the prosthesis, which is very often inclined in the actual procedure.

In particular, in the case of a bridge-type restoration connecting multiple teeth, many problems may occur in the insertion of the prosthesis even if the existing alveolar bone is placed to the maximum.

Alternatively, when using a superstructure method such as an abutment, the abutment portion may be excessively deleted to adjust the insertion path.

In this case, even if the margin of the gum does not fit correctly, the food is constantly stagnated between the gum and the prosthesis, even when the prosthesis is fastened, causing inflammation and occlusion.

In addition, there is a problem in that the holding force is easily removed from the weak holding force when mounted on the oral cavity and exposed to mastication pressure. Excessive rotational force or stress is concentrated on one implant attached by the lever arm effect, which may result in structure (fixtures, screws, abutments) dropping or fracture and fracture of the implant periphery.

On the other hand, when restoring the implant prosthesis, the screw type (Screw Retained Prosthesis (SRP) and Cement Retained Prosthesis (CRP)) is used as a type. Due to the movement of adjacent teeth, the gap is widened, resulting in food storage or packing, which occurs in almost all implants.In the process of removing and repairing prostheses, the cemented type is not easy to remove, increasing patient pain. There is a problem that all work must be rebuilt from scratch.

Therefore, the present invention has been proposed to solve the above problems, the problem of the present invention is to improve the structure of the abutment, while ensuring the maximum holding force while easily adjusting the insertion path at various angles to install and repair the prosthesis It is to provide an easy implant.

The present invention has been proposed in order to solve the above problems, the present invention relates to an abutment (Abutment coupled to fixture) embedded in the alveolar bone.

The abutment includes a body having a screw hole formed therein and coupled to the fixture; Prosthesis is protruded on the upper portion of the body is mounted, it is bent at a certain angle to provide an implant including a plurality of rods to secure the insertion path and the holding force of the prosthesis.

In addition, the present invention comprises the steps of (a) fixing the fixture by screwing, etc. to the alveolar bone;

(b) coupling an abutment to the fixture;

(c) bending a plurality of rods of the abutment at an angle to secure an insertion path;

(d) connecting the copings and taking impressions to produce prostheses; And

(e) providing an implant treatment method comprising mounting the prosthesis to a plurality of rods of an abutment, and bending the plurality of rods at an angle to support the prosthesis.

As described above, the implant according to the present invention has the following advantages.

First, by protruding a plurality of rods on the upper part of the abutment, and by forming a small diameter of the rods, the rods can be easily bent with a small force, thereby facilitating installation and repair of the prosthesis.

Second, by applying the abutment with a plurality of rods protruding to the artificial structure of the bridge type it is possible to maximize the insertion path and holding force.

Third, in order to preserve the amount of natural teeth as much as possible during the implant procedure, the method of minimizing the amount of hemorrhoids removed by a three-sided crown or a human crown is selected. In some cases, one side of the prosthesis may be exposed and guided to the formation of a screw hole.

Fourth, it takes about 1-6 months to fix the bone after the fixture is placed, and during this period, if a temporary prosthesis is made, it is possible to reuse the existing abutment by constructing the resin directly on the rod. Can be.

Hereinafter, the implant according to the present invention will be described in detail by the accompanying drawings.

As shown in Figures 2 to 4, the implant 10 proposed by the present invention is a fixture (11) embedded in the alveolar bone; An abutment (12) coupled to the fixture (11); A fastening member (14) for fixing the abutment (12) to the fixture (11); And a prosthesis 16 secured to the abutment 12.

In the implant 10 having such a structure, the fixture 11 is formed with a thread on the outer circumferential surface, and is implanted in the alveolar bone along the thread.

The implanted fixture 11 is fixed to the alveolar bone by fusing with the tissue of the alveolar bone. In general, it takes a long time for the threads and alveolar bone to fuse together.

In addition, a screw groove 20 is formed inside the fixture 11, and the fastening member 14 penetrating the abutment 12 is screwed into the screw groove 20. Thus, the abutment 12 may be integrally coupled to the fixture 11.

At this time, the fastening member 14 may include various materials, but preferably means a screw.

The abutment 12 is a multiple rod abutment in which a plurality of rods 26 protrude upward to support the prosthesis 16.

In more detail, the abutment 12 includes a body 22 having a screw hole 24 formed therein; It includes a plurality of rods 26 protruding on the upper portion of the body 22 and having a diameter d2 smaller than the outer diameter d1 of the body 22 to be easily bent to support the prosthesis 16. do.

In the abutment 12 having such a structure, the body 22 has an insertion hole 15 formed at a lower portion thereof, and an upper portion of the fixture 11 may be inserted into the insertion hole 15.

In addition, the screw hole 24 is formed in the body 22 in the vertical direction and communicates with the insertion hole 15.

Accordingly, the fastening member 14 passes through the screw hole 15 and is engaged with the screw groove 20 of the fixture 11 while the abutment 12 is inserted in the upper portion of the fixture 11. Abutment 12 may be integrally fixed to the fixture 11.

On the other hand, the plurality of rods 26 are protruded in the upper direction of the abutment (12) body 22. These multiple rods 26 are at least three or more, with about 4-8 being suitable. In addition, the plurality of rods 26 may have a circular cross section or may have a square or various cross sections.

In addition, the plurality of rods 26 may be arranged along a circle on the upper surface of the body 22 or may be arranged at an arbitrary position.

The rod 26 protrudes from the upper surface of the body 22 to a predetermined length and has a diameter d2 smaller than the diameter d1 of the body 22.

At this time, the diameter (d1) of the body 22 and the diameter (d2) of the rod has a ratio of, for example, 1: 0.1-0.3.

When the diameter d2 of the rod is larger than the range 0.1-0.3, bending is difficult due to its strength.

On the other hand, when the diameter d2 of the rod is smaller than the range 0.1-0.3, the strength of the rod is weak and it is difficult to stably support the prosthesis.

In addition, the material of the rod 26 may be a variety of materials, but preferably includes titanium or zirconium.

Therefore, the rod 26 may be variously bent at an angle of 0 degrees to 90 degrees, and preferably can be easily bent at an angle of 40 degrees, so that when the prosthesis 16 is mounted, the insertion path L of Easy to secure

That is, when performing the implant 10, the insertion path (L) of the abutment 12 and the prosthesis 16 should be secured, but according to the structure of the jaw or the form of the dental implant, the abutment ( It is very often the case that 12) is inclined.

Therefore, when the abutment 12 is inclined, the prosthesis 16 may be mounted after bending the rods 26 at a predetermined angle, preferably at an angle to secure the insertion path L. have.

In this way, the plurality of rods 26 can be easily bent at any angle, so that the insertion path L can be easily secured. In this case, in order to secure the insertion path L, some of the plurality of rods 26 may be cut.

In addition, a plurality of rods 26 are extended in all directions in the interior of the prosthesis 16 to be supported, it is possible to secure a stronger holding force.

In particular, when a plurality of implants (10) is performed, the insertion path (L) of each implant 10 is often not parallel to each other due to the dental shape.

In this case, as described above, the rods 26 of the implants 12 of the respective implants 10 are bent at a predetermined angle so that the insertion paths L of the respective implants 10 coincide in parallel so that the prosthesis 16 ) Can be easily mounted.

Moreover, the implant 10 of this structure can be applied to the bridge type artificial structure 30 as shown in FIG.

That is, a plurality of artificial teeth 30a, 30b, 30c are arranged in a row to form a bridge shape, and the artificial teeth 30a, 30c on both sides of the artificial teeth 30a, 30b, 30c are as described above. This is a method of applying the implant (32, 34).

In such a bridge-type artificial structure 30, the insertion paths (L) for the artificial teeth (30a, 30c) at both ends do not often match.

Accordingly, the insertion of both artificial teeth 30a and 30c by appropriately bending a plurality of rods 36 protruding into the abutment 40 of the implants 32 and 34 on which the artificial teeth 30a and 30c are supported. The furnace L can be easily secured.

On the other hand, during the implant procedure, to minimize the amount of hemorrhoidal removal by the three-sided crown or human crown in order to preserve the amount of natural teeth as much as possible, the prosthesis by a plurality of rods 26 as described above When the support 16 is stably supported, the holding force can be improved, thereby exposing one side of the prosthesis 16 and inducing a screw hole to be formed on the exposed surface.

In addition, the implant 10 requires a time of about 1-6 months until the bone adhesion after implantation of the fixture 11, and during this period for patients who need a temporary or functional temporary prosthesis 16, As the crown is made, the abutment 12 according to the present invention can be reused without having to discard the existing abutment 12 by directly building a resin on the rod 26.

Hereinafter, with reference to the accompanying drawings will be described in more detail the process of performing the implant using the abutment according to an embodiment of the present invention.

As shown in FIGS. 2 to 4, when the implant 10 is to be treated, the fixture 11 is first implanted by screwing into the alveolar bone or the like, and the abutment 12 is planted in the fixture 11. Carry out the first procedure.

And wait a few months until the alveolar bone and the fixture 11 is combined to produce a prosthesis 16. At this time, the temporary crown may be made due to aesthetics or the like during this period. In this case, the resin may be directly built on the plurality of rods 26.

In this case, even when the temporary crown is made, the construction of the resin may be facilitated by properly bending the plurality of rods 26.

In addition, in order to manufacture the prosthesis 16, a second position of exposing the implant 10 to the outside of the gum is required to understand the exact position and arrangement of the implant 10, which is variously constructed according to the structure of the jaw or the arrangement of the teeth. After the operation is performed to connect the coping to obtain the impression of the implant (10) and the impression is taken.

At this time, when the plurality of rods 26 exposed out of the gums do not coincide with the insertion path L, it may be matched with the insertion path L by bending appropriately.

The impression thus obtained is sent to a dental laboratory, which determines the polishing form of the abutment (12) based on the impression in the orientation and position for the even arrangement of the prosthesis (16). ).

When the prosthesis 16 is mounted on the rod 26 of the abutment 12, the cement bonding cement is filled in the tooth model and fixed to the abutment 12.

At this time, when the insertion paths L of the abutments 12 do not coincide with each other, the plurality of rods 26 are bent appropriately to match the insertion paths L.

Therefore, the prosthesis 16 can be easily attached to the abutment 12 in a state where the insertion path L is secured.
