A gnathodynamometer was constructed to study the effect of varying the degree of jaw opening on the maximum incising forces in 20 human subjects. The incising force was greatest when the gap (distance) between the incisal edges of maxillary and mandibular incisors was 17 +/- 3 mm. We suggest that with further refinement, the measurement of the optimum distance could be used to determine the occlusal vertical dimension. The IEMG was monitored simultaneously with the incising-force measurements. No relationship was found between the maximum incising force and the IEMG at different openings of the jaws.
制作了一种咬力计，以研究20名受试者中不同程度的张口对最大切割力的影响。当上颌和下颌切牙切缘之间的间隙（距离）为17±3毫米时，切割力最大。我们认为，经过进一步完善，最佳距离的测量可用于确定咬合垂直距离。在测量切割力的同时同步监测肌电图。在不同的张口度下，未发现最大切割力与肌电图之间存在关联。
