目的 利用新型(牙合)力分析系统(Tee Tester)测量个别正常(牙合)人群,获得牙尖交错位时的最大(牙合)力绝对值及其在各牙位的分布特点,为咬合相关研究提供客观数据支持.方法 共纳入29名21～32岁的个别正常(牙合)志愿者,使用(牙合)力分析系统测量牙尖交错位时的最大(牙合)力.同时取上下牙列模型测量各牙位宽度,分析得到最大(牙合)力在各牙位的分布.结果 全牙列在牙尖交错位的最大(牙合)力为(900±361) N[(335～1 727)N],最大接触面积为(515±115)mm2[(242～773)mm2].最大(牙合)力与咬合接触面积呈正相关关系(P＜0.001).磨牙区各牙位承受(牙合)力平均值为(107～156)N,同一象限中第一磨牙平均值高于第二磨牙;前磨牙区各牙位承受(牙合)力平均值为(39～66)N;前牙各牙位受力平均值为(11～33)N.结论 个别正常(牙合)在牙尖交错位时的最大(牙合)力个体差异较大.该(牙合)力分析系统可实时获得全口及各牙位(牙合)力绝对值数据,对评价个体(牙合)力及各牙位的(牙合)力分布有临床指导意义.“,”Objective To investigate the occlusal force in the position of maximum intercuspation in the population with individual normal occlusion using a new occlusal analyzing equipment (TeeTester).Methods Twenty-nine volunteers aged from 21 to 32 years were recruited.Occlusal analysis was performed using TeeTester.An arch model of each subject was retrieved in order to measure the tooth width and to calculate the force applied on each tooth.Results The occlusal force in the position of maximum intercuspation was (900±361) N (range:335-1 727 N).The maximum occlusal force was correlated with the contacting area.The mean value of occlusal force on the molars ranged from 107 to 156 N,with the mean value on the first molar greater than that on the second molar within the same quadrant.The mean value of occlusal force ranged from 39 to 66 N on the premolars,and from 11 to 33 N on the front teeth.Conclusions There is a great variation of occlusal force in maximum intercuspation in individual normal occlusion.TeeTester occlusal analyzing system provides absolute occlusal force in kilogram and can be cowerted to N,which may assist clinical examination in patients.
