The present invention relates to buffered implants.

In detail, the present invention is to improve the fastening force of the abutment coupled to the implant fixture and the artificial tooth molded outside the abutment, and can buffer the external force transmitted through the artificial tooth in the structure after the implant procedure. The shock applied to the alveolar bone is alleviated, and the periodontal inflow can be done so that there is a slight flow during the lateral movement so that there is no risk of being dislodged, and the abutment combination is improved to be embedded in the alveolar bone. It relates to a buffered implant which allows for improved fixation force.

In general, when a tooth is missing, a bridge procedure is performed in which a denture is inserted or a missing part is 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 form an artificial tooth root in the alveolar bone, by using an artificial tooth made similar to the actual tooth by using it to obtain the effect of the patient using the actual tooth.

The implant procedure is used to form a groove using a tool such as a drill to implant a fixture in the alveolar bone missing teeth, and performs tapping to fix the fixture inside the groove.

Thereafter, the fixture is inserted into the grooved groove, and an abutment is coupled to the upper side of the fixture by a fixing screw, and the implant is completed by molding-bonding the abutment to the abutment.

In the implant procedure, the fixture immobilized on the alveolar bone performs a root function of the tooth, and the abutment is a connection structure for integrating the artificial tooth and the fixture.

The fixture and abutment constitute an implant structure for firmly fixing an artificial tooth in a correct position. Such an implant structure is mainly made of a metal material such as titanium, which is excellent in physical / chemical rigidity.

On the other hand, the fixture has a screw portion of a dense pitch on the outer side of the alveolar bone due to the hard outer side of the alveolar bone and a soft inner side, and a screw having a wide pitch is formed on the inner side, .

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.

In other words, there is no means to alleviate the impact due to the absence of periodontal ligament in the treated part, and in case of lateral movement, it is almost defenseless in the case of lateral movement. Therefore, if it is used for such a long time, .

Accordingly, patients who have undergone an implant procedure complain of pain in the alveolar bone, and there is no means for relieving such pain.

On the other hand, the screw portion of the fixture, particularly, the large screw portion of the implant structure has a problem that the fixation force of the fixture is lowered because the density of the alveolar bone varies depending on the body characteristics of the patient undergoing the procedure.

In addition, because the abutment is coupled to the fixture by the screw tightening force of the fixing screw, it cannot be firmly fixed in the case of its own loosening phenomenon, and when the loosening phenomenon occurs, the entire abutment is shaken and the coupling force of the artificial tooth is dropped. Abnormality occurs.

Accordingly, the present invention, the cushioning material that serves as the periodontal ligament is formed in a cylindrical corrugated in the vertical direction and through the holder to improve the fastening force of the abutment and the artificial tooth formed outside the abutment through the holder. In addition, the external force transmitted through the artificial tooth formed by the implant procedure can be buffered to alleviate the impact applied to the alveolar bone, and the fixation force embedded in the alveolar bone is improved, so that there is no fear of detachment. The purpose is to provide an implant structure.

In addition, it is possible to secure a firm fixing state between the abutment and the fixture, and at the same time, it is possible to consider the problem of broken lower screw part when tightening, thereby maintaining a stable treatment state of the artificial tooth for a long time and Another object is to provide an implant structure that can be performed more efficiently.
