What is the range of forces reached during swallowing on the teeth or implants?
3-5 psi
How many times does a person swallow each day, according to the text?
480 times
Test your knowledge on measuring forces on teeth during chewing and swallowing, including recording forces on strain gauges and perioral musculature exertion. Explore the psi values required for different food types and the frequency of swallowing per hour.
