Abstract :Objective: The purpose of this study was to test the occlusal analysis system T-Scan II for the detection of a bite force reflex and to determine the net jaw reflex modulation during a rapid voluntary clench. Materials and Methods: Eleven subjects were asked to bite as fast as possible on the pressure-sensitive sheet using occlusal scanning system T-Scan II . The bite force reflex parameters were determined from the occlusal force curve. Results :The inhibitory bite force reflex occurred in nine subjects with a latency of 34.0 ± 7.8 ms, duration of 17.0 ± 2.8 ms and strength of 1.6% ± 0.3%. A strong correlation was detected between the latency of the reflex and the time to reach 80% of the maximal relative bite force insert ignore into journalissuearticles values(r = 0.833; p < 0.01);. A moderate correlation was found between the relative bite force at the moment of the first turning point of the reflex and the change of this force during the reflex insert ignore into journalissuearticles values(r = 0.677; p < 0.05);. Conclusion: The reflex modulation confirms the protective role of the jaw reflex: during faster bites the latency of the bite force reflex was shorter and with a higher bite force the strength of the reflex was greater.
