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.
