In 1991, We investigated evaluations of denture functions using the electromyography and the biting force measuring system in complete denture wearers. In 1992, masticatory activities and mandibular movements were registrated at the same time by use of the Mandibular Kinesiograph in five elderly complete denture wearers. Those subjects used old and new denture were evaluated to the mandibular movement, the masticatory movement and the masticatory activity from the start of the mastication of peanuts to the end of the swallow.We obtained the following results in this research.1) The calculated biting force were increased by use of new denture.2) Masticatory activities and cycle times during mastication of three test foods ( kamaboko, silverberry jelly and peanuts ) were compared ten complete denture wearers with ten natural dentitions. In all cases, Masticatory activities and cycle times were frequent in complete denture wearers than natural dentitions.3) Masticatory electromyogram and mandibular movement were registrated at the same time in five elderly complete denture wearers. Both opening, closing and lateral mandibular movement were more stable by use of new denture, and vertical velocity was also increase. Furthermore, coordination of masseter and temporal muscles were observed during mastication.

1991年，我们用肌电图和咬合力测量系统对全口义齿戴用者的义齿功能进行了评价。1992年，应用下颌运动记录仪对5例老年全口义齿患者的咀嚼活动和下颌运动进行了同步记录。本研究对使用新、旧义齿的受试者从咀嚼花生开始到吞咽结束的下颌运动、咀嚼运动和咀嚼活动进行了评价，结果表明：1）使用新义齿后计算的咬合力增加; 2）咀嚼三种测试食物时的咀嚼活动和咀嚼周期（kamaboko，银浆果果冻和花生）进行了比较，10个全口义齿戴者与10个自然牙列。3）5例老年人全口义齿患者的咀嚼肌肌电图与下颌运动同时记录。新义齿修复后，下颌的开、合运动及侧向运动均较修复前稳定，垂直运动速度也有所增加。此外，咀嚼肌和颞肌在咀嚼过程中的协调性也得到了观察。
