[Construction and testing of a strain gauge for measuring masticatory force].
The main objective of this study was to establish and test a measuring system for monitoring occlusal forces and force cycles during mastication. A measuring module using strain gauge transducers was incorporated in the bridge-pontic of a three part test bridgework. A load cell was used intraorally for loading and calibration. The test bridges were incorporated in the patient's mouth and calibrated in vivo using variable loads. The recording system was a special intensifying and processing system (Alpha 3000, Hottinger-Baldwin Messtechnik, Darmstadt, West Germany). The percentage errors registered for every test bridge in various in-vitro tests were below 2%. Clinically, occlusal forces resulting during chewing of 4 types of food of different consistency were measured in 5 subjects. The results were shown as continuous force cycles which reflect cybernetic guidance patterns of the masticatory system.
