This creation is a kind of implant,Comprising an ontology,The ontology one end is equipped with joining hole,End is locked in ontology other end formation,One first screwing section of outside circumference formation of the ontology,One second screwing section and a third screwing section,End is locked in first screwing section adjoining,Second screwing section connects the first screwing section and third screwing section,Ontology what the first screwing section disk sets the first thread,Second screwing section disk sets the second thread,Third screwing section disk sets third thread,Second thread forms double tooth peaks,And the grasping surface for protruding into the second thread is formed between double tooth peaks,Tooth of the tooth of first thread away from the tooth with the second thread away from all big what third thread away from,The grasping surface being arranged between double tooth peaks of second thread effectively increases the contact area of implant and jaw bone tissue,And then promote fixing power and adaptation and connectivity.本創作係一種人工植體，包含一本體，該本體一端設有組接孔，該本體另一端形成鎖入端，該本體的外側周面形成一第一螺合段、一第二螺合段及一第三螺合段，該第一螺合段鄰接鎖入端，第二螺合段連接第一螺合段與第三螺合段，該本體於第一螺合段盤設第一螺牙，第二螺合段盤設第二螺牙，第三螺合段盤設第三螺牙，第二螺牙形成雙牙峰，且雙牙峰之間形成伸入第二螺牙的抓持面，第一螺牙的牙距與第二螺牙的牙距皆大於第三螺牙的牙距，第二螺牙的雙牙峰之間設置的抓持面有效增加人工植體與顎骨組織的接觸面積，進而提升固持力與密合度與連結性。
