Abstract
A method for making a ceramic body comprised of a ceramic material having an inhibitory effect on bacterial growth is provided. A dental prosthesis may be made of a ceramic material that comprises a molybdenum-containing component on a portion of the prosthesis that contacts the gingival surface of a patient. In one method, a porous zirconia ceramic structure is shaped in the form of a dental prosthesis, and then infiltrated with a molybdenum-containing composition, before sintering to densify the ceramic structure.
Claims14
A method of making a sintered ceramic dental prosthesis for restoring dentition of a patient that inhibits bacterial growth, comprising
- a. obtaining a porous ceramic body comprising a shape of a dental prosthesis,
- b. obtaining a liquid molybdenum-containing composition comprising from 0.015 wt % to 5 wt % of a molybdenum-containing component, based on the weight of the molybdenum-containing composition,
- c. infiltrating the liquid molybdenum-containing composition into a first portion of the porous ceramic body that corresponds to a portion of the sintered ceramic body that contacts a gingival surface of the patient, and
- d. sintering the infiltrated porous zirconia ceramic to form the sintered ceramic dental prosthesis.
