Claims
- 1. A process for fabricating a dental material comprising:mixing ceramic powder and one or more media together to achieve homogeneity throughout the mixture and to form a putty; applying the putty to a model to conform to the shape of the model and to form a ceramic core material; and sintering the model with the putty thereon for a time of less than about three hours to provide a dental ceramic core material.
- 2. The process of claim 1 wherein the dental ceramic core material is highly dense.
- 3. The process of claim 1 wherein the dental ceramic core material comprises mechanical properties having a low standard deviation.
- 4. The process of claim 1 wherein the ceramic powder comprises a glass-ceramic, a glass powder, a ceramic powder or mixtures thereof.
- 5. The process of claim 1 wherein the ceramic powder comprises a material selected from alumina, zirconia, mullite, spinel, porcelain, titania, lithium disilicate, leucite, amorphous glass, lithium phosphate, and mixtures thereof.
- 6. The process of claim 1 wherein the dental ceramic core material is an orthodontic appliance, bridge, space maintainer, tooth replacement appliance, splint, crown, partial crown, denture, post, tooth, jacket, inlay, onlay, facing, veneer, facet, implant, abutment, cylinder, or connector.
- 7. A process for fabricating a dental material comprising:applying a putty to a model to conform to the shape of the model and to form a ceramic core material, whereby the putty comprises ceramic powder and one or more media having homogeneity throughout the putty; and sintering the model with the putty thereon for a time of less than about three hours to provide a dental ceramic core material.
- 8. The process of claim 7 further comprising applying a layer of material selected from the group consisting of glass, ceramic, and glass-ceramic on the sintered dental ceramic core material and sintering the layer of material to the dental ceramic core material.
- 9. The process of claim 7 further comprising applying a layer of composite resin material on the sintered dental ceramic core material and curing the layer of composite resin material to the dental material.
- 10. A process for fabricating a dental material comprising:mixing ceramic powder and one or more media together to achieve homogeneity throughout the mixture and to form a putty; applying the putty to a model to conform to the shape of the model and to form a ceramic core material; and sintering the model with the putty thereon for a time in the range of about one minute to about five hours to provide a dental material.
- 11. The process of claim 1 wherein the sintering time is in the range of ten minutes to one hour.
