The present invention relates to an implant structure. According to the present invention, a fastening force is improved between an abutment coupled with an implant fixture and an artificial tooth molded outside the abutment, structure rotation is prevented after a procedure despite an external force transmitted through the artificial tooth, bacterial formation is reduced and gingivitis is prevented during food intake and mastication because the penetration of the food is blocked by a protruding annular ring and an O-ring of a buffer, which results in an extended service life of the implant, an abutment upper holder or the artificial tooth can be brought into closer contact with a jar-type prominent portion of the buffer when the abutment upper holder is fixed with a fixing screw, and a buffering function for mitigating an impact applied to an alveolar bone is provided so that the buffering function is achieved as desired. To this end, the present invention provides a jar-type buffer implant including a fixture that is implanted into an alveolar bone； a fixing screw that is screw-coupled from above the fixture； a buffer that is coupled with the circumference of the fixing screw, is positioned in an artificial tooth, buffers a force transmitted through the artificial tooth, and is formed of a soft material； and an abutment upper holder and an arranged abutment lower holder that are coupled with the circumference of the fixing screw and are positioned above and below the buffer, reinforce a fastening force between the buffer and the fixing screw, and completely cover the buffer, in which a cemented artificial tooth is received by the abutment upper holder so as to have a buffering function.본 발명은, 임플란트 픽스츄어에 결합되는 어버트먼트 및 어버트먼트 외측에 성형되는 인공치아의 체결력을 향상시키도록 하며, 시술 후 인공치아를 통해 전달되는 외력에도 구조물들이 회전되지 않고, 음식물 섭취 저작 시, 완충재의 돌출환상 링과 O링이 음식물의 침투를 차단하여 주므로 세균의 배양을 줄여 치은의 염증을 방지하므로 임플란트의 수명을 연장할 수 있으며, 고정나사로 어버트먼트 상부홀더를 고정하면 완충재의 항아리형 풍융부로 어버트먼트 상부홀더나 인공치아를 더 밀착할 수 있고, 제대로 완충기능을 할 수
