Chewing patterns in dentate and complete denture wearers - recorded by light-emitting diodes.
Chewing patterns of ten dentate and eleven edentulous test subjects were recorded by a computer based on light-emitting diodes and photosensitive detector-surfaces (Selspot-system). A comparison of the mandibular pattern between the two groups was made with respect to chewing rhythm and degree of mandibular displacement and velocity. Differences could be found between these two groups showing a higher chewing rhythm and mandibular velocity in the dentate group. Also greater chewing-cycles were performed by the dentate persons. These differences seemed to some extent have followed as a results of adaptation to a complete denture situation.
