What is bio-esthetics?

This word was first used by Dr. Robert Lee in the 1970's when he was engaged in studying the mouths of older people who had no evidence of breakdown or deterioration in any of the components of their chewing systems.

He defined it as "the study or theory of the beauty of living things in their natural forms and functions."

The results of his studies were ground breaking to say the least.  He discovered that in mouths that stayed healthy for a lifetime there were always three bio-mechanical principles at work.  These “bio-esthetic principles” represented the reason why some people’s mouths stood up to the test of time, whereas others did not.
