In an assembly constituted by a drill and a tenon for anchoring a dental prosthesis adapted to be fixed in the root of a tooth the drill has a diameter slightly larger than that of the tenon at all points along its length. The tenon and the drill have similar meridian profiles and each is constituted by two coaxial cylindro-conical parts of large and small diameters respectively, the cylindro-conical part of small diameter comprising a cylindrical part connected to the small base of the conical frustum of the cylindro-conical part of large diameter projecting out of the root of the tooth. The tenon and the drill terminate respectively in their truncated end part of small diameter, of which the angle of taper is selected so as to ensure a wedging of the truncated end part of small diameter of the tenon in the corresponding truncated end part of the drilled hole. Futher the truncated end part of the tenon as a length shorter than that of the drill.

The present invention relates to an apparatus for transferring a pasty matter for filling a hollow body. This apparatus comprises a cylindrical bowl in which the pasty matter to be transferred is placed and of which the bottom is extended by an axial tube open at its two ends, a push member being engageable in the bowl to push the pasty matter towards and in the axial tube, this push member having an outer diameter substantially equal to the inner diameter of the bowl and having an axial bore passing therethrough and a piston constituted by a rod of diameter equal to the inner diameter of the axial tube extending the bowl, housed and slidable in the axial bore of the push member to be engaged in the axial tube of the bowl and empty this tube of the pasty matter that it contains.
