Study of occlusion contact of intercuspal position on different body positions of young adults with normal occlu-sions
摘要
Abstract
Objective To study the occlusal contact of maximum intercuspation of the young adults with normal occlu-sion on positon of sitting up, 45° recline and supine position. Methods Occlusion contact process of 135 young adults with normal occlusion were examined with T-scanⅢ digital occlusal analysis system on three positions respectively. Re-sults The number of contact points on first contact frame (χ2 =0. 074, P=0. 963) and the highest force value on the maximum interaction area frame (χ2 =0. 071, P=0. 964) have no significant difference among three different body posi-tions. Conclusion There is no obvious relation between initial contact tooth and body position. The teeth with highest force value at maximum interaction area frame were concentrated on the molar area, which is relatively less on anterior teeth and premolar teeth area.关键词
