Description

Implant combined prostheses that are easier to perform and correct {Omitted}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an implant-supported prosthesis that can be easily manipulated and corrected, and more particularly, to an implanted prosthesis that is coupled to an implanted implant, facilitates coupling of an implant and an associated prosthesis, To an implant-bonded prosthesis which is easy to be combined and separated and which is easy to be corrected and corrected.

A tooth implant is a fixture that is placed in or on the jaw to support the restoration of a missing tooth.

It is usually referred to as an artificial tooth or a third tooth that is placed in the gums and gums.

By implanting a biocompatible implant body on the jawbone that has been enlarged so that it can be adequately wrapped through additional operations such as bone grafting and osseointegration on the site of the tooth defect or the jaw bone of the site where the tooth is extracted, It is a dental treatment technique.

After the osseointegration, which is a morphological, physiological and direct coupling between the jawbone and the surface of the implanted body, which is maintained normal function, is performed, the bone is subjected to a bone remodeling process of the peri-implant jaw.

These implants are generally used in the form of screw-shaped bone implants, which are screwed into the upper part of the implant (abutment).

As described above, in the conventional method of fastening with the screw fastening method, the screw is loosened and the screw is broken.

In addition, since teeth must be punctured to fix the teeth to the implant, the aesthetic effect and durability are weakened, and the tooth (crown or metal) should be destroyed when the problem occurs after implant placement.

The conventional method of fastening by the screw fastening method is inconvenient to the patient due to the additional cost, time spent in the additional treatment and operation, and inconvenience that the adhesive should be adhered in the oral cavity when the crown and the combined structure are combined. , Inflammation and periodontitis are often caused by residual adhesive.

In order to solve this problem, the present invention is characterized in that a special characteristic structure that can be easily coupled without using a screw fastening method does not cause loosening and fracture, and it is not necessary to make a hole in a tooth, It is also possible to prevent weakening.

In addition, when the problem occurs after implantation, the implant can be easily separated without destroying the tooth, thereby developing an implant-attached prosthesis that is easy to perform and correct the inconvenience to the patient.
