Abstract: The present invention relates to an assembly for forming an interface part for dental implants with variable height. The assembly comprises a tubular interface part with a central axis and an auxiliary part which is coupled to the interface part. In a coupled position: the auxiliary part is integral with the interface part at least in a sense of direction parallel to the central axis; a final segment of the abutment protrudes through an upper end of the auxiliary part; and a peripheral surface outside the abutment comprises at least one planar face in a plane which intersects with the final segment of the abutment and the central axis. The planar face of the auxiliary part serves as a guide for cutting the abutment at a specific height.

Abstract: A dental prosthetic structure for implant, including a tubular interface part with an axial through passage for a fixing screw; a tubular-shaped prosthetic element coupled to the interface part with an axial through passage for the fixing screw; and a securing element for securing the prosthetic element to the interface part, with an axial through passage for the fixing screw, and being introduced in the passage of the interface part and in the passage of the prosthetic element for securing the interface part and the prosthetic element, such that the axial through passages of the interface part, the prosthetic element and the securing element are aligned forming a passage for the fixing screw.
