<p>The present invention relates to a dental implant associated with an artificial tooth. An abutment type artificial tooth comprises: a prosthesis mounted on a fixture having a shaft hole formed inside and implanted into a jawbone, and an upper mounting portion; and a lower fastening shaft portion inserted into the shaft hole of the fixture so as to be resiliently combined to the fixture, wherein an impact buffer portion for more effectively buffering impact due to lateral external pressure or an occlusal force in various directions is provided at an abutment, a resilient fastening portion to be resiliently combined to the fixture is provided at the lower portion of the impact buffer portion, and the durability of a resiliently fastened portion is semipermanently maintained irrespective of an occlusal force in various directions due to numerous repeated occlusions by separating the impact buffer portion and the resilient fastening portion. Therefore, it is possible to greatly increase the lifetime of an implant and facilitate implantation.</p> |
