The purpose of this study was to evaluate the influence of the recovery of masticatory function on QOL in elderly edentulous patients. Four items were evaluated, and the following results were obtained :1. The mean maximum biting force and mean impulse in 63 edentulous patients aged over 65 years was calculated. The mean maximum biting force was 19.3 kgf in males (31 patients), and 17.7 kgf in females (32 patients). The mean impulse was 3.9 kgf/s in males, and 3.7 kgf/s in females.2. After establishing a questionnaire regarding complaints and uncomfortable symptoms of dentures, their causes, and social factors, which were considered related to the improvement in QOL, investigation using the questionnaire was performed in 81 edentulous patients. Factor analysis of the results obtained was performed, in which patients' complaints of denture were classified into 4 factors. Furthermore, a questionnaire consisting of 4 items and 27 questions was completed.3. The influence of recovery of masticatory function on QOL in elderly edentulous patients was evaluated. Masticatory function was evaluated by masticatory test and biting force during clenching. Measurment was perfomed 5 times. QOL improved with the improvement in masticatory function. Furthermore, it was suggested that QOL of patients' activity and psychological aspects improved by the long-term retention of the improvement in masticatory function.4. Influence of the strength and acting direction of biting force occurring during clenching in elderly edentulous patients on the recovery of masticatory function and QOL was evaluated. Although masticatory function and QOL improved and biting force increased by the insertion of new dentures, no difference were noted in the acting direction of biting force between when old dentures were being used and after completing adjustment of new dentures.

本研究旨在探讨咀嚼功能恢复对老年无牙患者生活质量的影响。评估了四个项目，得到以下结果：1。计算63例65岁以上无牙患者的平均最大咬合力和平均冲量。男性31例，平均最大咬合力为19.3 kgf，女性32例，平均最大咬合力为17.7 kgf。男性平均冲动为3.9 kgf/s，女性平均冲动为3.7 kgf/s。对81例无牙患者进行义齿投诉、不适症状、原因、社会因素等与生活质量改善有关的问卷调查。对所得结果进行因子分析，将患者对义齿的主诉分为4个因素。问卷共4项27题。评价咀嚼功能恢复对老年无牙患者生活质量的影响。通过咀嚼试验和咬合时的咬合力评价咀嚼功能。测量5次。生活质量随咀嚼功能的改善而提高。此外，长期保留咀嚼功能的改善可以改善患者的活动和心理方面的生活质量。评价老年无牙患者咬合时咬合力的强弱和作用方向对咀嚼功能恢复和生活质量的影响。虽然植入新义齿改善了咀嚼功能和生活质量，并增加了咬合力，但在使用旧义齿时和完成新义齿调整后，咬合力的作用方向没有差异。
