Description

Protective Mechanism for Stability of Custom Implants

The present invention relates to a protective mechanism for the initial stability of the custom implant, and more particularly to an implant aid for the stable bone adhesion of the custom implant medium that replicates the extraction target implanted in the alveolar bone.

Dental implants, usually made of titanium, are used to fix the implant cartilage of an artificial tooth to the jawbone to provide teeth to patients with poor natural teeth. When the implant carcass is completely ossified with the gum bone, After the abutment is connected to the upper part, a suitable final crown in the form of a tooth is connected to the upper part to complete the treatment. The location of the abutment and implant carcass is important for the final positioning of the prosthesis, which is important.In the early stages of the implantation of the implant fixture into the alveolar bone, the bone adhesion to fully fuse with the alveolar bone The healing period is important. 'Adhesion' refers to the fusion of artificial tooth roots, which are screw-type implant media implanted through implantation, with the bone cells of the human body. It's a losing phenomenon. This osteoadhesion period refers to a period of time waiting for the bone cells and implants to stably bind for 3 to 6 months, and this initial stability is known to determine the success or failure of the implant surgery. In particular, experts warn that disrupting bone adhesion during this period can result in implant failure or side effects.

It is an object of the present invention to provide an auxiliary mechanism for stably fixing a customized implant replica of a tooth to be extracted to the alveolar bone.

Another object of the present invention is to provide a mechanism for preventing direct stimulation of a customized implant replicating a tooth to be extracted.

In the present invention for achieving the above object in the auxiliary device 100 of the custom implant replica of the tooth extraction, the adhesive portion 10 is bonded to the adjacent teeth 200 of the custom implant 300 replicating the tooth extraction And, it is formed on one side of the adhesive portion 10, characterized in that it comprises a protective part 20 to form a concave surface 21 at one end.

Preferably, the customized implant 300 replicating the extraction target tooth is an implant fixation body manufactured by imaging the three-dimensional space 401 of the alveolar bone 400 into which the root of the extraction tooth is inserted. Further, the auxiliary device 100 is made of zirconia or dental resin or metal, and the adhesion is performed by chemical treatment of 35% concentration of phosphoric acid gel. In addition, the adhesive portion 10 is a porous structure, the protective portion 20 is to cover and form a gap with the surface of the exposed portion 30 of the top of the custom implant.

According to the present invention as described above, the bonding portion 10 forms a porous structure, thereby increasing the bonding strength with the adjacent teeth 200. In addition, there is an effect of preventing direct stimulation of the custom implant 300 implanted by forming a gap between the custom implant 300 and the protection unit 20 that replicates the implanted extraction target tooth. In addition, it is possible to reduce the need for additional surgery by protecting the customized implant 300, which is a duplicate of the extraction target tooth produced by the individual customization.

The conventional screw-type implant that is standardized is placed in the alveolar bone 400, and then further surgery or procedure such as gum bone graft, maxillary sinus elevation, etc. is performed in the periodontium 500 until bone fusion with the alveolar bone 400 is achieved. Allow it to heal while buried. As such, the implant requires a period in which the alveolar bone 400 and the osteoseotegration occur, which may take about 3 to 6 months, is a major initial stability stage to determine the success or failure of the implant procedure. Can be. On the other hand, a custom implant 300 manufactured by duplicating a tooth to be extracted can be manufactured to be connected to the root portion and the head of the tooth, the custom implant cloned the tooth to extract is naturally periodontal (500) Since it may be exposed outside, there may be a high risk of being affected by excessive load during the bone adhesion healing period, and therefore, an auxiliary device 100 is needed to prevent irritation caused by peripheral irritation or continuous chewing force in the oral cavity.
