摘要： A model of at least a part of a dental structure, an articulator, and methods of manufacturing such devices are provided. The model and the articulator can be used to approximate the natural movements of a jaw of a patient to facilitate preparation of a dental restoration. The model can include the dental structure, an interface, and at least one void extending from a reference surface of the interface inwardly toward the void. The articulator can include upper and lower portions on which models of upper and lower dental structures can be held. The upper and lower portions of the articulator can be configured to generally maintain a vertical alignment while at least one gap formed between respective first and second alignment components thereof allows horizontal movability of the upper and lower portions relative to each other to test the interfit of the models therebetween.

摘要： The systems and methods disclosed herein employ a scanning system for capturing highly detailed three-dimensional representations of dental subject matter that may be used to virtually model a variety of dental objects, including dental hardware, appliances, and prosthetics, as well as interim components of dental manufacture such as waxups, investment casts, and the like. These digital models may be used with fabrication technologies such as stereo lithography, three- dimensional printing, computerized milling, and the like to manufacture dental objects precisely fitted to the dentition of individual dental patients. In one aspect, the systems and methods disclosed herein employ a combination of digital three-dimensional modeling and rapid fabrication technologies to provide pre-indexed, pre-registered, and/or precut components for articulated dental models. Dental articulators and components of dental models as described herein may use a positioning key to encode positional information for components of the dental model, and/or a reference grid on mounting surfaces to enforce local accuracy of fabricated parts against a fixed reference array.

摘要： A dental model tray (12) for use in forming a dental model has a rigid bottom wall (16) and a relatively thin side wall (17) extending upwardly from the perimeter of the bottom wall (16) to form an open-topped cavity which is adapted to receive the dental casting material. The bottom wall (16) and the side wall (17) are formed integrally of polymeric material with the side wall (17) being joined to or attached to the bottom wall (16) by a thin membrane-like connector member (19) that is formed integrally with the perimeter bottom wall (16) and a lower side edge of the side wall (17). The connector member (19) is frangible and easily broken so that the side wall (17) can be torn away from the base and discarded after dental casting material has hardened in the cavity formed by the side wall (17).
