How taking an ear impression has changed in 50 years!
Ear impressions are taken for many reasons: Ear Molds for Hearing Aids, Musicians, Hunters, Swimmers, Cell Phone Users, Dentists, Industrial Workers, Truck Drivers, Airline Personnel, etc.
In 1950 plaster of paris was used to duplicate the outer ear. Can you imagine removing that cured impression?
Thank goodness we no longer have to put our clients through that!
Tune in next month to see how we have progressed over the years.
