In the present study, we assessed the relation between dental status and fall in a sample of 253 volunteers(105 men and 148 women) free-living adults and elderly people in Japan by a questionnaire survey. The mean group rate and number of people who had fallen during the past 3-year period were 24. 1% and 3. 36 times, respectively. Among those who had fallen, the proportion who had lost the occlusal supporting zone was 29. 7%, while the proportion who maintained the occlusal supporting zone was 21. 4%. Then, we also investigated the influence of change in dental occlusion on the stabilization of posture stance disturbed by electrical stimulation of unilateral lower limb in healthy 5 adults volunteers with dental splint occluded anterior teeth only and 5 healthy elderly people with denture. When the occlusal supporting zone was transiently lost by insertion of dental splint, both and maximum ground reaction force were increased. In the elderly people with dentures, maximum ground reaction forces in both anterior-posterior and medial-lateral directions with teeth clenching on wearing denture were smaller than that with teeth clenching on wearing no denture. The present results suggested that maintenance of dental occlusion throughout life would be possibly effective for not only preserving better the masticatory function but also preventing falls later in life.

在本研究中，我们通过问卷调查评估了253名志愿者（105名男性和148名妇女）自由生活的成年人和老年人的样本中的牙齿状况与跌倒之间的关系。在过去三年中跌倒的人数和人数分别为24。1％和3。36倍。在跌倒的人中，失去咬合支撑区的比例为29。7％，而维持咬合支撑区的比例为21。4％。然后，我们还研究了牙齿闭塞变化对健康的5名成年志愿者的单侧下肢刺激受到电刺激的姿势立场的稳定影响的影响，该姿势刺激受到牙齿夹板的牙齿前牙齿的刺激的影响，仅牙齿前牙齿前牙齿，只有5名健康的老年人。当通过插入牙齿夹板瞬时咬合支撑区时，增加了地面反应力和最大地面反应力。在具有义齿的老年人中，前后和内侧方向的最大地面反作用力，牙齿紧握牙齿的牙齿的牙齿握紧牙齿的牙齿小于牙齿，牙齿紧握的牙齿不穿牙齿。目前的结果表明，维持牙齿阻塞一生可能不仅有效地保留更好的咀嚼功能，而且还可以防止以后的生活。
