Abstract: A dental reconstruction includes a connection device with a first end bearing on an anchor and a second end supporting a prosthesis. The cross section decreases between the first end and the second end. The connection device defines a through-hole and an abutment. A fastening screw screws into an internally threaded portion of the anchor in order to fasten the connection device. A blocker has a cross section that increases upon insertion of the fastening screw into the through-hole. The blocker fits into a groove of the prosthesis covering the connection device. The screw head has a circular section bearing on the blocker in order to deform the blocker and fit the blocker into the groove of the prosthesis.

Abstract: A method for reversible fixing of a tool to an implantable element, when fitting of a dental prosthesis is performed, comprises, in a first step, reversible fixing of a hollow intermediate connecting part onto an external complementary part of the tool. In a second step, the method consists in placing the tool equipped with the intermediate connecting part, on the end of the implantable element until the intermediate connecting part clips onto an external complementary part of the implantable element. The hollow intermediate connecting part is preferably fixed by clipping or screwing onto the external complementary part of the tool.
