Transfixed multiple dental prosthesis intended to be attached and fixed to a plurality of dental implants by several transfixing screws, each having a shank with a threaded portion intended to be received by screwing in a respective dental implant. Each transfixing screw is held captive in a respective bore formed in the transfixed multiple dental prosthesis and extending along a respective axial direction. Each transfixing screw is movable in rotation about the axial direction of the respective bore and is movable in translation along the axial direction of the respective bore between a retracted position and at least one screwing position. In the retracted position, the threading of the threaded portion of the transfixing screw does not protrude from the bore.
