可摘局部义齿或全口义齿患者的咀嚼功能与全口天然牙患者的咀嚼功能不同。本研究的目的是表征咀嚼功能减少之间的关系，在咀嚼性能和咬合力方面，和剩余的自然咬合支持的存在，通过Eichner指数评估。118例可摘局部义齿和全口义齿患者被选作分析。这些受试者被分为四组，这取决于咬合支持的数量。70名牙齿受试者完全咬合支持被指定为对照组。在所有受试者的第一磨牙区测量双侧咬合力。使用改良咀嚼性能指数评估咀嚼性能。花生被用作测试食物。咬合力和咀嚼性能与组分类显著相关。此外，无论是咬合力和咀嚼性能的四个义齿组相比，对照组显着降低，这种趋势是显着的义齿组无咬合支持。这些结果表明，功能牙单位的存在可能是一个关键因素，在保存咀嚼功能。
Patients with removable partial dentures or complete dentures do not demonstrate masticatory function to the same level as patients with a full set of natural teeth. The purpose of this study was to characterize the relationship between reduction of masticatory function, in terms of masticatory performance and bite force, and the existence of remaining natural occlusal supports as assessed by the Eichner index. One hundred and eighteen removable partial denture and complete denture wearers were selected for analyses. These subjects were divided into four groups depending upon the number of occlusal supports. Seventy dentate subjects with full occlusal support were designated as a comparison group. Bilateral bite force was measured at the first molar region in all subjects. Masticatory performance was assessed using the modified Masticatory Performance Index. Peanuts were used as the test food. Both bite force and masticatory performance were significantly associated with group classification. Moreover, both bite force and masticatory performance of the four denture groups were significantly reduced compared to the comparison group and this tendency was remarkable for the denture groups without occlusal support. These results suggest that the existence of functional tooth units may be a key factor in preservation of masticatory function.
