Description

Dental implant prosthesis combination assembly

The present invention relates to a dental implant, and more particularly, by having a structure in which a crown can be easily attached and detached while minimizing the use of cement for adhesion, simple and effective maintenance and repair after dental implant surgery. It relates to a dental implant prosthesis combination assembly that can be performed.

An implant originally refers to a substitute that restores human tissue when it is lost, but in dentistry, it refers to a series of procedures that implant artificial teeth.

To replace the lost root (root), a fixture made of titanium, etc., which does not have a negative reaction to the human body, is planted in the alveolar bone from which the tooth has escaped, and then the artificial tooth is fixed to restore the function of the tooth. It is a procedure to do.

In the case of general prostheses or dentures, the surrounding teeth and bones are damaged over time, but implants do not damage the surrounding tooth tissue.

Artificial teeth treatment (also called implant or implant treatment) varies depending on the type of fixture, but after drilling an implantation location using a predetermined drill, the fixture is placed in the alveolar bone to osseointegrate into the bone, and then air After joining the abutment, it is usually completed by placing the final prosthesis, the crown, on the abutment.

Dental implants improve the function of dentures for partially and completely edentulous patients as well as single missing tooth restorations, improve the aesthetics of dental prosthetic restorations, and further dissipate excessive stress on the surrounding supporting bone tissue. It also helps to stabilize the dentition.

In general, such dental implants include a fixture placed as an artificial tooth root, an abutment coupled to the fixture, and an abutment screw for fixing the abutment to the fixture. ), and a crown that is an artificial tooth coupled to the abutment.

However, in such a conventional dental implant, when a certain amount of time passes after the dental implant procedure and the screw such as the abutment screw is loosened, it may be necessary to partially or completely remove the crown in order to re-tighten it. , even if a partial fracture occurs in the crown, it may be necessary to partially or completely remove the fractured crown in order to attach a new crown.

In other words, when maintenance and repair of dental implants are performed after dental implant surgery, it is difficult to attach or detach a dental implant such as a crown or abutment, so that the patient suffers from excessive treatment or the cost of the procedure is high. There is a problem of increasing.

In addition, if the fixture, the abutment, and the crown are simply bonded using cement instead of screw bonding, the same problem may occur, and the remaining cement used for bonding may cause inflammation in the gums around the implant. There are problems that adversely affect hygiene, etc.
