The invention relates to an anchoring assembly for the anchoring of a dental prosthesis. The anchoring assembly includes a plurality of dental implants, each having a threaded portion and an abutment having a threaded hole, a plurality of pins each of which configured to be mounted on one of the abutments and has a through axial cavity, a plurality of blocks, each having a through hole configured to receive a respective pin, and a plurality of telescopic arms. The telescopic arms and the blocks includes coupling means. By rotating the pins about their axes relative to the abutments it is possible to raise or lower the arms relative to the abutments and adjust their inclination. The configuration of the anchoring assembly can be locked by way of suitable glues, thereby allowing removal of the anchoring assembly and integration into a dental prosthesis.
