Description

Dental components and holder for the same

The present invention relates to a dental component and a holder for the procedure, and more particularly, to a dental component having a structure that can support each other so that directionality can be intuitively recognized when the dental component is fastened to an abutment; It relates to the holder for the operation.

In general, an implant used in dentistry refers to forming a tooth after implanting a metal having the root shape of a tooth into the jawbone in a portion where a tooth is partially or entirely lost in the oral cavity to adhere to the bone.

In the procedure of artificial teeth using implants, first, through drilling and tapping on the alveolar bone, a groove corresponding to the size of the implant is formed, and a fixture mount is fastened to the upper part of the implant. After that, the implant fixture is implanted in the alveolar bone using a surgical hand piece, and then the fixture mount is removed from the implant. Then, the primary operation is completed by fastening the cover screw to the upper part of the implant and suturing the implant. The cover screw serves to prevent bacteria and foreign substances remaining in the oral cavity from entering the implant while waiting for osseointegration of the implant. The period of osseointegration varies somewhat depending on the patient's bone quality and implantation location, but generally takes 3 to 5 months.

After that, the gums are opened through a secondary operation to expose the cover screw, the degree of osseointegration of the implant is checked, and the cover screw is removed. Next, a healing cap is fastened to the upper part of the implant to prevent the gum from covering the space where the artificial tooth is to be placed and to form an aesthetic gum, and wait for a certain period of time. Finally, after confirming the aesthetic gum formation, the healing cap is removed, and the impression coping is fastened to the upper part of the implant to manufacture the prosthesis.

Subsequently, a preliminary impression is taken in the oral cavity using an impression material, and the impression coping is removed. Through this, the abutment and the prosthesis are completed, the abutment is fastened to the upper part of the implant, and the prosthesis is fixed on the abutment to complete the artificial tooth.

In the case of a detachable abutment in this series of dental procedures, a dental component such as a post or a healing cap is fastened or separated from the base abutment. There was a problem very inconvenient for the operator to confirm and align the corresponding direction for the fastening operation.
