Description

Compatible gum protection abutment{Compatible gum protection}

The present invention relates to a compatible gum protection abutment, and more specifically, it is possible to be mixed with a surgical procedure, secures a proliferation space of the gum, and replaces the prosthesis for prosthesis without damaging the proliferated gum. It relates to a compatible gum protection abutment.

Implant (dental implant) refers to a procedure or replacement for implanting an artificial tooth made by a dentist.

For example, the implant may refer to a series of procedures to restore the function of the tooth by fixing an artificial tooth after planting an alternative tooth root that can replace the root (root) that is lost in the alveolar bone from which the tooth has escaped.

In addition, the implant may refer to a substitute that restores when human tissue is lost. In this case, the implant is a fixture, an abutment fixed to the fixture, and an artificial tooth. It may include a crown (crown) forming the appearance of.

In the case of general prostheses or dentures, there is a risk that, over time, the surrounding teeth and bones, especially the surrounding dental tissue, may be damaged.

However, the implant does not damage the surrounding dental tissue, and has the advantage of being able to be used semipermanently because it has the same function or shape as natural teeth, but does not cause cavities.

In addition, the implant has the advantage of improving the function of dentures and improving the aesthetic aspect of dental prosthetic restorations, as well as single-defective restorations, as well as partially and completely edentulous patients.

Furthermore, implants are often performed in dentistry because they help to disperse excess stress on surrounding support bone tissue and help stabilize teeth.

On the other hand, implants performed in dentistry can be divided into a surgical process of placing a fixture on the gum bone, that is, an alveolar bone, and a prosthetic process of attaching an artificial tooth by connecting an abutment to the placed fixture.
