    Abstract: Methods of making an impression of dental tissue and dental articles (e.g. suitable for dental impression) are described. In one embodiment, the method comprises providing a hardenable composition, comprising a resin system, a filler system, and an initiator system wherein the hardenable composition is a hardenable self-supporting material having sufficient malleability to be formed into a shape. The method further comprises placing said hardenable composition in contact with dental tissue such that an impression of at least a portion of the dental tissue is formed in the hardenable composition. The method further comprises curing the hardenable composition comprising the impression.

  • Publication number: 20130277874
    Abstract: A method of making a multilayer all-ceramic dental appliance. A first article can be formed of a first material based on a first digital surface representation having a desired outer shape of the dental appliance. A portion of the first article can be removed to form an outer layer comprising a cavity dimensioned to accommodate an inner layer. A second article can be formed by filling the cavity of the first article with a second material. The second article can be further processed, as desired. For example, a desired inner shape can be formed in the second article. Such a desired inner shape can be based on a second digital surface representation of a dental object configured to receive the dental appliance. At least one of the first article, the outer layer, and the second article can be fired, for example, while still being coupled to a support.

  • Publication number: 20130081272
    Abstract: A method of making a multi-chromatic dental appliance. A first article can be formed of a first material based on a first digital surface representation having a desired outer shape of the dental appliance. A portion of the first article can then be removed to form an outer layer of the dental appliance comprising a cavity dimensioned to accommodate an inner layer. A second article can be formed by filling the cavity of the first article with a second material. The second material can have at least one different optical property than the first material. The second article can be further processed, as desired. For example, a desired inner shape of the dental appliance can be formed in the second article. Such a desired inner shape can be based on a second digital surface representation of a dental object configured to receive the dental appliance.
