The Gnathograph
The Gnathograph, or 'dental articulator', was the invention of Los Angeles dental surgeon Beverly McCollum. He was also the founder, in 1926, of the Gnathologic Society.
The name 'Gnathograph' derived from 'gnathology,' this being the study of the jaw and masticatory system, from the greek word 'gnathos' meaning 'jaw'.

"The formidable contraption shown in the mouth of Miss Pearl Nord is a gnathograph, invented by Dr. Beverly B. McCollum of Los Angeles and demonstrated before the chicago Dental Society. It records direction of bite and fit of teeth and accurately guides a dentist in straightening crooked teeth or fitting inlays, crowns, bridges and plates."
