1. A scan body element insertable in or on a dental implant, or insertable in or on an implant analog, and recognizable in or with an optical scanning system arranged to permit determining orientation and position of the scan body element, the scan body element comprising:
a top part comprising at least one geometric feature being an angled planar surface recognizable in the optical scanning system, a lower part made of a metal or metal alloy and shaped to fit to the dental implant or the implant analog, the lower part being fixed to the top part, the lower part engaged with an inner portion of the top part via a press-fit connection formed by an interference fit between an upper portion of the lower part and a lower portion of the top part, wherein the lower part includes at least one circumferential protrusion that engages with the inner portion of the top part, and a central part arranged in a central bore of the lower part, the central part comprising a threaded portion and a first end with a recess configured to receive a screw driver through the top part such that the threaded portion is turnable relative to the lower part so as to fasten the scan body element to the dental implant or the implant analog, wherein the top part comprises an opening, and said opening of the top part and said central bore of the lower part are arranged for insertion of a screw driver such that the screw driver is received in the recess of the central part, wherein the top part is a solid polymer element, and the lower part is fixed to the top part by the at least one circumferential protrusion, wherein the top part, the lower part and the central part are assembled together so as to form a single element, wherein said central part is interlocked between the lower part and the top part, and wherein said opening of said top part is smaller than said first end of said central part. |
