1. An assembly for forming an interface part with variable height for a dental implant, said dental implant comprising a dental implant body implanted in a bone, a dental prosthesis fixed to said dental implant body and said interface part interposed between said prosthesis element and said dental implant body, wherein said assembly comprises:
an interface part having a tubular shape with a central axis and comprising: a base end for seating said interface part on a dental implant body, a pillar for integrally attaching a prosthesis element to said interface part, said pillar being coaxial with said central axis and extending from said base end to a free end of said pillar, and an inner conduit coaxial with said central axis going through said interface part from said free end to said base end forming a passage for a set screw, said inner conduit being provided with an inner rib which forms a seating for a head of the set screw,
at least one auxiliary part formed for being coupled in a detachable manner to said interface part, such that in a coupled position: said auxiliary part is coupled to said interface part so that it cannot move relatively to said interface part at least in a direction parallel to said central axis; a final segment of said pillar, adjacent to said free end, protrudes through an upper end of said auxiliary part; said upper end of the auxiliary part forms a peripheral surface outside said pillar, said peripheral surface comprising at least one planar face in a plane; and said plane of the planar face intersects with said final segment of the pillar and said central axis; so that said plane defined by said planar face is a cutting plane for cutting said pillar with a cutting tool along said plane at a specific height which is predetermined by the actual dimensions of said auxiliary part, thereby enabling to modify the height of said interface part; wherein said auxiliary part is configured to be removed from said interface part prior to formation of said dental implant, and
a tool for attaching said auxiliary part to said interface part in said coupled position, so that said auxiliary part cannot move relatively to said interface part in the direction of said central axis, said tool comprising a rod which moves in a through hole of said auxiliary part and presses, with its end, the outer surface of said interface part.
