<p>A dental prosthesis (6) comprises an outer shell-like body (4) of fully fired porcelain material into the cavity of which is placed porcelain powder (5); that porcelain powder (5) being partially fired so as to remain coherent when the prosthesis (6) is pushed over a tooth preparation (1) to mould the porcelain powder to the shape of that tooth preparation. After the fitting process the prosthesis (6) is fired to complete firing of the now shaped porcelain powder (5) before final fitting of the prosthesis (6) to the tooth preparation.</p> |
