Using both quartz- and foil-based piezo-electric force transducers, occlusal forces during swallow, simulated chewing, and maximum effort were evaluated in 19 long-face and 21 normal individuals. Forces were measured at 2.5 mm and 6.0 mm molar separation. Long-face individuals have significantly less occlusal force during maximum effort, simulated chewing, and swallowing than do individuals with normal vertical facial dimensions. No differences in forces between 2.5- and 6.0-mm jaw separation were observed for either group.
使用基于石英和箔的压电式力传感器，对19名长脸个体和21名正常个体在吞咽、模拟咀嚼和最大用力时的咬合力进行了评估。在磨牙间距为2.5毫米和6.0毫米时测量力。与面部垂直尺寸正常的个体相比，长脸个体在最大用力、模拟咀嚼和吞咽时的咬合力明显更小。两组在颌间距2.5毫米和6.0毫米时的力均未观察到差异。
