Research Abstract	Silicone resilient denture liner shows significantly high masticatory performance and this may be related to extension of occluding time in initial phase of mastication. Acrylic resilient denture liner failed to show additional effect than conventional acrylic denture on masticatory performance. These results indicate that silicone resilient denture liner does decrease in stress propagation speed, thus indicate extended occluding time and increase in masticatory performance in clinical situation.
