Research Facts
Dr Ralph and Mrs Olga Crawford donated their extensive Canadian dental collection to the DCF to create the museum in 1997; further donations were received while Dr Crawford was Curator Emeritus at the Dental Canada Museum until its closure in 2008; this item was donated by Dr. Carmen Cavallin from Vancouver, British Columbia; this item was patented in 1934 by James Sorenson; it was used to take accurate occlusal measurements of a patient's face in order to construct dentures; it was based on the idea that there is a fixed law regarding face measurements: the vertical distance from the pupil to the naso spinale is equal to the vertical distance from the centre of the lip line to the bottom of the mandible; the instrument used the patient's pupil as a fixed point of calculation for all measurements; the two rulers are not originally from the same product
