| 摘 要： | 目的:评价支持功能牙单位在可摘义齿修复后对口腔咀嚼功能的影响。方法:选择114例可摘义齿患者,根据前磨牙区和磨牙区的支持功能牙的分布和义齿类型分为4组,60例后牙区无缺失牙无修复者作为对照组,测定各组的咀嚼效率和最大咬合力。结果:咀嚼效率和咬合力与分组的不同有明显的相关,4个测试组的咀嚼效率和最大咬合力显著低于对照组,有支持的测试组PD1的咀嚼效率和最大咬合力较其他3个测试组存在显著性差别。结论:在前磨牙和磨牙区支持牙功能单位对义齿修复后咀嚼功能的恢复有很重要的意义。

| Abstract: | Objective To study the influence of functional tooth units on masticatory function in removable denrure wearers. Method One handred fourteen removable denture wearers were selected for analysis.These subjects were divided into four groups,depending on the number of occlusal supports functional tooth units.Sixty dentate subjects with full occlusal support were designated as a comparison group.Bilateral bite force and masticatory efficiency were measured. Results Both bite force and masticatory efficiency 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 functional tooth units.Conclusion These results suggest that the existence of functional tooth units may be of great value to the rehabilitation and preservation of masticatory function. |
