<p>In the production of ceramic dental prostheses, a model of the tooth is made; a slurry is prepared, consisting of a suspension of metallic oxide particles in water; the model of the tooth is brought into contact with the slurry; the layer of metallic oxides is given the external shape which it is desired to confer upon the infrastructure of the prosthesis; the model of the tooth thus covered with metallic oxides is baked in order to effect a slight solid-phase sintering of the metallic oxide particles; and a glass is used to impregnate the infrastructure thus sintered at a sufficient temperature.</p> |
