Mandibular movements during mastication before and after rehabilitations with new complete dentures recorded by...

Mandibular movements in wearers of complete dentures were registered before and after rehabilitation with new dentures by light-emitting diodes (LEDs). The duration of the opening, closing and occlusion phases as well as the whole chewing cycle were studied. The closing phase had the longest duration of the three phases, 0.36 s, and represented 45% of the duration of the total chewing cycle. Only minor changes in the movement pattern were found when comparing different test-foods and after rehabilitation with new dentures.
