A multi-piece manual dental implant structure includes a dental implant body, a supporting body and a tooth cover. The dental implant body includes an implant part, an abutting part and an auxiliary fixing part arranged between the implant part and the abutting part. The implant part is fixed to a bone layer and a surface bone layer located at a surface of the bone layer. The auxiliary fixing part is fixed to a soft tissue layer at a side of the surface bone layer apart from the bone layer. The supporting body includes a connection part connected with the abutting part, and a positioning part. The tooth cover includes an accommodation space for accommodating the supporting body, and an auxiliary supporting part for connecting the auxiliary fixing part. The present invention enhances horizontal supporting force of the supporting body by the auxiliary fixing part extended out of the surface bone layer in cooperation with the auxiliary supporting part of the tooth cover, so as to reduce possibility of breakage of the supporting body due to the horizontal sheer force.一種多件式人工植牙結構,係包含有一植牙體、一支臺體以及一牙套件。該植牙體具有一植入部、一頂接部以及一設置於該植入部與該頂接部之間的輔助固定部,該植入部固定於一骨質層以及一位於該骨質層表面的表皮骨頭層,而該輔助固定部則固定於一位於該表皮骨頭層遠離該骨質層一側的軟組織層。該支臺體具有一與該頂接部連接的連接部以及一定位部。該牙套件具有一容置該支臺體的容置空間以及一配合連接該輔助固定部的輔助支撐部。本發明藉由凸出於該表皮骨頭層外的該輔助固定部配合該牙套件之輔助支撐部加強該支臺體之水平方向的支撐力,降低該支臺體受到水平剪力之作用而斷裂的機率。11...植入部12...頂接部13...輔助固定部21...骨質層22...表皮骨頭層23...軟組織層30...支臺體31...連接部311...穿孔32...定位部40...牙套件41...容置空間42...輔助支撐部50...螺鎖元件
