Description

Implant Infrastructure with Buffer Function

The present invention relates to an implant structure having a buffer function.

In detail, the present invention to buffer the external force transmitted as it is through the artificial tooth without the periodontal ligament after implantation in the structure to alleviate the impact applied to the alveolar bone, thereby preventing a lot of deviation during the existing lateral movement Of course, the present invention relates to an implant structure having a cushioning function to further improve the fixation force embedded in the alveolar bone.

In the case of missing teeth, a bridge procedure was performed in which a denture was inserted or a missing part was covered with a metal by using a surrounding tooth as a pillar. However, such a procedure has a number of problems, such as a false teeth or bridges artificial teeth chewing food and adversely affects the surrounding teeth.

As a result, an implant procedure has emerged as a procedure of advanced dental care. This implant procedure is to create an artificial tooth root in the alveolar bone, by using the combined artificial teeth made similar to the actual teeth by using this to obtain the effect of the patient using the actual tooth.

The implantation process is used to form a implantation groove using a tool such as a drill to implant a fixture in the alveolar bone where the tooth is missing, and then implant the fixture inside the implantation groove and then abutment the fixture. ), And the implant is completed by combining artificial teeth with the abutment.

The implant implanted in the alveolar bone during the implant procedure as described above performs the root function of the tooth, the abutment is a connection configuration to integrate the artificial tooth and the fixture. The fixture and abutment become an implant structure for firmly fixing the artificial tooth in place, and the implant structure is mainly made of a metal material such as titanium having excellent physical / chemical rigidity.

On the other hand, the fixture has a tight pitch of the outer side of the alveolar bone due to the characteristics of the outer side of the alveolar bone is tight, the screw portion of a wide pitch is formed in the section of the inner side to increase the fixing force of the buried state Let's go.

While the implant structure has a high physical / chemical strength, when the external force is transmitted through the artificial tooth by the high strength, the impact is applied to the alveolar bone.

Accordingly, the patient who has undergone an implant procedure complains of alveolar bone pain, and there is no means for alleviating such pain.

In addition, when the impact is excessively transmitted to the implant structure, it may be shaken out afterwards. In particular, during the lateral movement, the implant surgical part is applied to the impact as it is without the periodontal ligament, thereby rapidly weakening the fixation of the implant structure.

Thus, when the impact is repeated several times, a serious problem occurs that the implant itself is shaken off the alveolar bone.

In addition, even in the case of large teeth such as molars, only one type of implant was used as a single implant, and according to the size of the tooth, the impact force received was much, and it was shaken well. Caused by.

On the other hand, the screw portion, especially the large screw portion of the implant structure of the implant structure has a problem that the fixing strength of the fixation state of the fixture is lowered because the density of the soft alveolar bone is different by the physical characteristics of the patient undergoing the procedure.

The present invention has been invented to solve the above problems.

Accordingly, the present invention, by buffering the external force transmitted through the artificial tooth formed by the implant procedure to mitigate the impact applied to the alveolar bone, and at the same time, in the case of large teeth such as molar teeth adopts a double-type structure It is an object of the present invention to provide an implant structure so that the fixing force embedded in the alveolar bone can be further improved.

It is configured to be fixed.

In addition, the present invention is the fixture is embedded in the alveolar bone in two numbers spaced apart from each other with respect to one artificial tooth, and correspondingly the cushioning material is extended to be interposed between the two fixtures and the abutment to be fixed It is composed.

On the other hand, the fixture is formed by alternating arrangement of the large screw portion and the small screw portion formed on the outer surface to increase the fixing force embedded in the alveolar bone.

As described above, according to the present invention, the external force transmitted through the artificial tooth is reduced by the shock flow applied to the alveolar bone by reducing the structure by the sealing rubber and the rubber ring, which is a cushioning material coupled with the structure, thereby reducing the pain felt in the alveolar bone. A reduction effect is obtained, and the procedure can overcome the disadvantage that there is no periodontal ligament.

In addition, the present invention can be performed by providing a double-type structure in the case of a large tooth, such as molar teeth, there is an effect that can double the bearing capacity of the implant to mitigate the impact of the existing lateral movement.

In addition, the present invention is obtained by the configuration in which the large screw portion and the small screw portion alternately arranged to obtain the effect that the fixed fixing force of the fixture in response to various physical conditions of the patient.
