Absorption of impact force of an experimental mouth guard material prepared from PEMA (Polyethylene methacrylate) powder and divinyl sebacic at a P/L ratio of 1.2 g/1 ml had been evaluated by a new impact testing device. Commercial mouth guard materials mainly composed polyvinyl-acetate-polyethylene (EVA) copolymer were also been tested. The experimental mouth guard material showed minimum impact transmission. Among the various thickness, 1 mm EVA copolymer and 2 mm experimental material showed better impact absorption from 50 cm height with a free falling steel ball.
