Dental appliances including multiple components and a system and method for constructing the same are disclosed herein. The dental components are designed to fit together to form the dental appliance. The components of the dental appliance are electronically modeled, printed, and pressed sequentially, separately, or as a unitary piece. Forming the dental appliance from multiple components enables each component of the dental appliance to be formed from a different material, each material having different features associated with it. In various embodiments, different materials have different colors, textures, opacities, and transformation factors associated with them. Furthermore, each component can be formed from multiple components. In some other embodiments, a support structure is designed and constructed in order to minimize deformation of a dental component during fabrication of the component.

A method, apparatus, and article of manufacture is disclosed for providing a dental crowns using electronic models, and more particularly to a method, apparatus, and article of manufacture for creating dental crowns using a lost-wax manufacturing process from electronic model files corresponding to patient teeth impressions and corresponding electronic models for tooth crowns. The system and method permit the electronic generation and specification of crown, bridge, and implant dental appliances that may be specified in an industry standard file specification. This specification is utilized in a rapid prototyping process to generate a wax impression for the appliance that may then be fabricated using standard lost-wax fabrication techniques.
