Abstract: The invention relates to a dental prosthesis and to a material for making it. It applies to a dental prosthesis of the type comprising a metal support, and at least one reconstruction mass fixed to the metal support, at least the major portion of the reconstruction mass being made of a composite material containing a polymer binder in which an inorganic filler is dispersed. According to the invention, the reconstruction mass has a bending strength of not less than 100 MPa, and it possesses a Vickers hardness which is not less than 450N/mm.sup.2. The invention is applicable to dental prostheses.

Abstract: Device for filling a receptacle (R) by lowering it onto a needle (5) which pierces it. The portions of the installation adjacent to the bottom of the receptacle (R), which could be polluted by ill-timed projections of liquid from the needle, are washed and dried by nozzles (27, 28, 29) for washing the zones potentially reached by the projections, as well as the needle (5) itself, this washing and drying being followed by drying by suction orifices (38).
