Non-cemented threaded implants

Abstract

The present invention relates to a non-adhesive screw-type implant that can be firmly attached without additional adhesives when bonding dental braces and abutments, and can maintain a strong and stable joint state under repeated chewing , including: a fixed body, implanted in the groove of the alveolar bone formed in the oral cavity; an abutment, combined with the fixed body, to have a supporting structure supporting lateral or horizontal pressure; A fixed body, which is combined on the abutment; and a screw, which is inserted through the dental crown and the abutment, the upper end is placed around the inner peripheral surface of the dental crown, and the lower end is inserted and fixed on the upper end of the fixed body central.

Description

technical field [0001] The present invention relates to a non-adhesive screw-type implant, and in more detail, relates to an implant that can be firmly bonded without additional adhesives when bonding dental crowns and abutments, and is also resistant to repeated chewing. Non-cemented threaded implants that maintain a strong and stable bond. Background technique [0002] Implants, also known as dentures or third set of teeth, are additional operations such as bone grafting and bone elongation performed on the jawbone at the position of tooth defect or tooth extraction, so that the volume of the jawbone can be fully wrapped and enlarged, and It is a dental treatment operation method that restores the function of natural teeth by planting an implant body that is suitable for the human body. [0003] After completing the morphological, physiological, and direct combination of the jawbone that maintains normal functions and the surface of the implant body, that is, osseointegra...

Problems solved by technology

[0007] However, when treating a damaged tooth, after removing the top of the damaged tooth and covering the crown with a metal material to replace the artificial crown, the metal material will expose the outside of the tooth and make the treated teeth and gums unsightly. Zirconia material similar to the color of teeth

[0008] When using the above-mentioned artificial dental crown formed of zirconia material, the part that is in contact with the abutment is bonded with an adhesive. At this time, the abutment is made of metal, so it is difficult to use an adhesive to bond, and It is firmly attached to the artificial crown made of zirconia, so it cannot maintain a firm and stable joint state under repeated chewing after surgery, and gaps occur on the bonding surface of the artificial crown and abutment, while The problem of foreign inflow occurs
