Description

Title: TITANIUM MULTIPLE ABUTMENT FOR DENTAL IMPLANT FOR DENTAL IMPLANTS

The present invention relates to a titanium-based multipurpose abutment for dental implants, and more particularly, to a titanium-based multipurpose abutment for dental implants, which can be used not only for connection of a fixture and an artificial crown, The present invention relates to a titanium-based multipurpose abutment for use with a titanium alloy.

In general, implants are replacements that restore tooth tissue when it is lost, but dental implants are artificial tooth implants. It is a procedure to replace the lost root (roots) and plant the teeth in the alveolar bone that has passed through the teeth, and fix the artificial teeth to restore the function of the teeth.

In general prostheses or dentures, the surrounding teeth and bones are damaged over time, but the implants do not injure the surrounding dental tissue, and they have the same function and shape as the natural teeth, but do not have cavities. Therefore, they can be used semi-permanently.

Implants also improve the function of dentures in patients with single missing teeth restoration, as well as partial and total toothless teeth, and improve the aesthetic aspects of dental prosthesis restoration. Furthermore, it helps to stabilize the dentition as well as to disperse the excessive stress applied to the surrounding supporting bone tissue.

The dental implant procedure is divided into a gingival bone, that is, a surgical procedure for placing an implant on an alveolar bone, and a prosthetic procedure for attaching an artificial tooth by connecting an abutment to an implanted implant.

There are a variety of implants that can be used in a variety of ways.

First, drilling and tapping are performed on the alveolar bone to form a groove conforming to the size of the fixture, and a mount is fastened to the top of the fixture. Then, using a surgical handpiece, the fixture and mount are inserted into the alveolar bone, and then the mount is removed from the fixture, thereby placing the fixture in the alveolar bone. The first operation is completed by fastening the cover screw to the top of the fixture and sealing the fixture.

The cover screw prevents bacteria and foreign substances present in the oral cavity from entering the fixture while waiting for the fixture's osseointegration. The duration of osseointegration differs somewhat depending on the patient's bone quality and implantation position, but generally, 3 to 6 months are avail- able.

Next, the gums are opened through the second operation to expose the cover screws, check the degree of fusion of the fixtures, and remove the cover screws. For aesthetic gingival formation, the healing abutment is fastened to the top of the fixture and waited for two to three weeks. In order to improve the complexity of such a second procedure, a first-aid procedure for fastening the healing abutment is omitted, omitting the process of fastening and removing the cover screw.

Next, after the aesthetic gum formation is confirmed, the abutment abutment is removed, and the impression coping is fastened on the fixture to manufacture the prosthesis. The impression material is then used to create a preliminary impression in the mouth and remove the impression coping.

Then, a tooth model is prepared, the artificial crown is pierced, an abutment is fastened to the top of the fixture, and an artificial tooth is completed by fixing a prosthesis, that is, an artificial crown, on the abutment.

However, in the case of the prior art, since the impression coping for impression taking and the abutment to be fastened on the fixture are divided into separate members, all the steps must be performed during the implant procedure, There is a problem that the cost required for manufacturing increases.
