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.
