假设下颌骨应变模式是一个很好的指示磨牙咬合力模式在M。通过确定等长咬合过程中下颌骨应变模式和咬合力模式之间的关系来测试咀嚼过程中的束肌。在沿M1-M2区域沿着将传感器等长绑定期间，使用绑定到M2根部下方的下颌骨皮质骨的玫瑰花应变计确定骨应变模式。通过比较两个不同玫瑰花记录的骨应变模式来确定咀嚼期间玫瑰花位置对骨应变模式的影响;一个结合在M2根部下方，另一个结合在M3根部下方。来自两个实验组的数据支持这样的假设，即沿着下颌骨工作侧的骨应变模式沿着是在动力冲程期间咬合力模式的良好指示器。骨应变模式和咬合力模式之间的关系并不完美，两个主应变值不相等。在一般情况下，主压缩是一个更好的指标咬合力比主张力。
The hypothesis that mandibular bone-strain patterns are a good indicator of molar bite-force patterns in M. fascicularis during mastication was tested by determining the relationship between mandibular bone-strain patterns and bite-force patterns during isometric biting. Bone-strain patterns were determined using rosette strain gauges bonded to mandibular cortical bone below the roots of the M2 during isometric binding on a transducer along the M1-M2 region. The effects of rosette position on bone-strain patterns during mastication was determined by comparing bone-strain patterns recorded from two different rosettes; one bonded below the roots of the M2 and the other below the roots of the M3. The data from the two experimental sets support the hypothesis that bone-strain patterns along the working side of the mandible are a good indicator of bite-force patterns during the power stroke. The relationship between bone-strain patterns and bite-force patterns was not perfect and the two principal strains were not of equal value. In general, principal compression was a better indicator of bite force than principal tension.
