Abstract
Measurements of intraoral muscle force with foil strain gauges load cells and pressure transducers bonded to a Tru Tain stent and to a lip bumper appliance were tested by means of seven functional exercises in five adult subjects over a 5 day interval The measuring devices and the functional exercises were tested for replicability and validity Results showed that the pressure transducer was the superior measuring device with respect to size sensitivity thermal compensation factory uniformity replicability and validity The device most susceptible to error on the basis of these factors was the foil strain gauge Of the seven functional exercises used the pronunciation of the words phone mom and church and the exercise of swallowing were replicable over time The other three exercises chewing gum sucking and blowing on a straw were determined to be unreliable in terms of replicability over time Overall pressure values recorded were significantly higher than in previous reports Pressure values were higher for the Tru Tain stent than for the lip bumper
