It is very important to evaluate the denture function of elderly denture patient. In order to perform for this study, we have developed a system of the calculating the biting force and the pressure distribution under the denture.This system consists of many components which have an electromyograph, a force transducer, a pressure sensor, a dynamic strain amplifier and computerized data analysis system.The biting forces, electromyograms and pressure distributions in three complete denture patients were recorded simultaneously and were analyzed by using this system.Electromyograms of the right and left anterior temporal and masseter muscles were led by four electrodes.Pressure distribution on supporting tissue were measured by seven pressure transducer attached to the basal surface of the duplicated mandibular denture.Before occlusal adjustment of the complete denture, it was recognized to disperse pressure distribution. The biting force from intergrated EMG were low degree.However, after occlusal adjustment it was indicated to converse pressure distribution. The biting force was also high degree.By proceeding of the occlusal adjustment, it was acknowledged that load supporting capacity and biting force in complete denture wearers had increased.Compared with old denture, new denture in an elderly patient showed high biting force and displayed adequate distribution of pressure.

对老年义齿患者进行义齿功能评价是非常重要的。为了进行这项研究，我们研制了一套由肌电仪、力传感器、压力传感器、动态应变放大器和计算机数据分析系统组成的咬合力和义齿下压力分布计算系统。应用该系统对3例全口义齿患者进行了肌电图和压力分布的同步记录和分析，用四个电极引导咬肌，用附着于下颌复义齿基托表面的七个压力传感器测量支持组织的压力分布，在全口义齿调牙合前，应注意分散压力分布。整合肌电图测得的咬合力值较低，但调牙合后咬合力分布有匡威的趋势。咬合力也很高，通过咬合调整，全口义齿的承载能力和咬合力都有所提高，1例老年患者的新义齿与旧义齿相比，咬合力更高，压力分布更均匀。
