Abstract: A device for verifying the shade of a patient's teeth for the fabrication of a dental restorative comprising a mold section and a section for holding a shade tab, both of which are disposed on the shaft or rod of the device. A shade tab is formed in the mold section by applying composite material in the mold and curing it. The composite material is selected by the dentist based on the shade of the patient's teeth. After the composite material is cured, the resultant shade tab is removed from the mold and placed in the holder for the shade tab. This enables a dentist to effectively match the shade of a patient's teeth in order to provide a restoration that matches the patient's teeth.

Abstract: A dentistry aid is comprised by a recording system which is concerned with occlusion and related movements of the condyles in the tempero mandibular joints of a patient. Condyle movement, occurring in working the jaws and teeth, is known to be a complicated three-dimensional movement. The recording system of the invention is employed to carry out a method of sensing changes in positional relationship of the condyles with reference to respective maxilla cavities, and determining and recording condyle movements in at least three dimensions. Data obtained by this method constitute a valuable adjunct to the dental profession, particularly in connection with occlusion adjustment.Included in the recording system of the invention is a pair of cooperating frame structures comprising an upper stationary frame part attachable to the teeth of the upper jaw and a lower movable frame part attachable to the teeth of the lower jaw.
