Three edentulous patients were evaluated using the kinesiograph and a specially designed computer program to identify the length of eccentric contacts between their dentures when masticating test foods. Three different interchangeable occlusal arrangements were constructed and tested. Results of the evaluation of more than 1,400 chewing cycles showed that while 25% of masticatory contacts were eccentric, the great majority of contacts were within a distance of 1 mm from centric occlusion. More eccentric contacts occurred in the opening phase than might be expected. Posterior tooth form did not appear to affect the range of eccentric contacts.
使用肌动描记器和一个专门设计的计算机程序对三名无牙患者进行评估，以确定他们在咀嚼测试食物时假牙之间的非正中接触时长。制作并测试了三种不同的可互换咬合排列。对超过1400个咀嚼周期的评估结果表明，虽然25%的咀嚼接触是非正中的，但绝大多数接触都在距正中咬合1毫米的范围内。在开口阶段出现的非正中接触比预期的要多。后牙形态似乎不影响非正中接触的范围。
