Contradictory results are still reported on the influence of dental occlusion on the balance control. We attempted to determine whether there are differences in balance between opposed dental occlusion (Intercuspal position (ICP)/“Cotton rolls” mandibular position [CR]) for two extreme levels of stability (stable/unstable). Twenty-five subjects were monitored under both dental occlusion and level of stability conditions using an unstable platform Balance System SD. The resulting stability index suggests that body balance is significantly better when dental occlusion is set in CR (p < .001) in unstable but not in stable conditions. Occlusal traits significantly influencing postural control were Angle Class (p < .001), crowding (p = .006), midline deviation (p < .001), crossbite (p < .001), anterior open bite (p = .05), and overjet (p = .01). It could be concluded that the sensory information linked to the dental occlusion for the balance control comes strongly into effect in unstable conditions.

Older adults have unstable balance compared with younger adults, and the amount of body sway increases with more challenging foot positions that reduce the base of support and also with removal of vision ( Gill et al., 2001 ). The altered posture control in older people is also evident during the

Life expectancy has increased and reached an average of 71.4 years ( World Health Organization, 2015 ). The aging process involves changes in body structures and function that can lead to decreased strength and flexibility as well as a decline in coordination and balance. Indeed, unstable balance
