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.
