An implant component is arranged on a alveolar bone and comprises an implant, a abutment and a locking element.The implant was placed in the alveolar bone.The abutment in this creation is used to combine with the implant, and includes a cone-shaped stopper and an elastic buttress.The cone-shaped limit part is provided with a base locking channel, and has a cone-shaped limit outer wall substantially matching the cone-shaped limit groove.The elastic buttress top includes an elastic buttress structure extending from the cone-shaped limit part.The locking element comprises a locking head and a locking rod body.The self-locking head of the locking rod body extends out.There is a tolerance gap between the locking channel of the abutment and the locking rod body.When the abutment is combined with the implant, the elastic butting structure first butts against the limiting groove wall compared with the cone-shaped limiting part, so as to restrain the relative rotation of the two parts； when there is deviation error between the implant and the abutment, the locking rod uses the tolerance gap to pass through the locking channel of the abutment.一種植牙組件，係設置於一齒槽骨，並包含植體、基台與鎖固元件。植體設於齒槽骨。本創作中之基台係用以結合於植體，並且包含錐狀限位部與彈性抵頂部。錐狀限位部設有基台鎖固通道，且具有實質配合錐狀限位槽之錐狀限位外壁。彈性抵頂部包含自錐狀限位部延伸出之彈性抵頂結構。鎖固元件包含鎖固頭與鎖固桿體。鎖固桿體自鎖固頭延伸出。基台鎖固通道與鎖固桿體之間具有允差間隙。當基台結合植體時，彈性抵頂結構較錐狀限位部先抵頂於限位槽壁，藉以抑制兩者相對轉動；當植體與基台存在偏位誤差時，鎖固桿體利用允差間隙而穿過基台鎖固通道。
