Problems: Correlations between the occlusal situation and the movement apparatus are currently controversially discussed in literature. However, studies with athletes are missing in this area. Therefore the question arises, whether a systematic block of the occlusion by a silicone panel shows effects on the postural control in athletes. Methods: In this study 16 male volunteers of a team of 1. Handball league were investigated. With the help of 1 or 2 mm thick silicon panel their occlusion was blocked symmetrical and asymmetrical. The effects in terms of their postural control were recorded on a force plate (GP Multisens, GeBioM, Münster/Germany).
