A tooth implant assembly with an elastic fault-tolerant part includes an implant, a abutment and a locking element.The implant is provided with a cone-shaped limiting groove extending along the axial direction of the implant. The cone-shaped limiting groove is composed of the limiting groove wall, and the limiting groove wall and the axial direction of the implant have a groove wall inclination angle.The abutment is arranged on the implant and has the abutment axial direction, including a cone-shaped limiting part and an elastic fault-tolerant part.The cone-shaped limiting part extends along the abutment axial direction and is contained in the cone-shaped limiting groove, and has a cone-shaped limiting wall, and the cone-shaped limiting wall has a abutment limiting inclination angle with the abutment axial direction.The elastic fault-tolerant part includes the elastic fault-tolerant structure, which extends from the cone-shaped limit part.The inclined angle of the groove wall is smaller than the limited inclined angle of the abutment. When the abutment is combined with the implant and there is deviation error between the abutment and the implant, the elastic fault-tolerant structure produces elastic deformation to reduce the deviation error.一種具有彈性容錯部之牙體植入組件，包含植體、基牙與鎖固元件。植體設有沿植體軸向延伸之錐狀限位槽，錐狀限位槽由限位槽壁圍構而成，限位槽壁與植體軸向具有槽壁傾斜角。基牙設置於植體，具有基牙軸向，包含錐狀限位部與彈性容錯部。錐狀限位部沿基牙軸向延伸設置，並容置於錐狀限位槽，且具有錐狀限位壁，錐狀限位壁與基牙軸向具有基牙限位傾斜角。彈性容錯部包含彈性容錯結構，彈性容錯結構自錐狀限位部延伸出。槽壁傾斜角小於基牙限位傾斜角，在基牙結合於植體而與植體之間產生偏位誤差時，彈性容錯結構產生彈性變形以縮小偏位誤差。
