Definitions

  • the present invention relates to a dental abutment and an implant, and more particularly, to an artificial tooth (prosthesis/crown) that is attached and fixed through a subsequent process by configuring the upper part of the column part as a tack type having a 'T'-shaped structure in cross section.

  • an implant is an artificial tooth structure formed through a dental treatment method to replace a missing or lost tooth. It replaces the function of natural teeth by inserting them into areas without bones and gums due to tooth loss due to disease, accidents or tumors, and restores aesthetic beauty through restoration of artificial teeth.
  • These implants are basically a fixture to be placed in the alveolar bone, an abutment fixed to the fixture and supporting lateral or horizontal pressure in response to the occlusal force applied during mastication (abutment, abutment), and the abutment It includes artificial teeth (prosthetics/crowns) that restore aesthetic beauty similar to natural teeth by restoring the upper part of the tooth.
  • a fixture is placed in the alveolar bone of the recipient, and then the abutment is fixed. And, it is restored by combining the artificial tooth on the upper part of the abutment.
