[Measurement of the clenching force during needle point registration in dentulous patients].

In this study the clenching force was measured, which 12 patients used, while the needle-point tracing was in progress. The patients were not instructed about the measurement. The results show, that 10 of 12 test persons used higher clenching forces, when they had to do border movements according to verbal instructions then when doing free movements of the mandibula. All test persons showed peaks in the level of the clenching force, which were clinically accompanied with swallowing.
