对一种低断裂强度的实验性人工试验食品(Optocal)和Optosil(R)在全口义齿佩戴者和自然牙列受试者咀嚼过程中的粉碎性进行了比较。这两种测试食物的粉碎显示，假牙佩戴者和有牙齿的受试者之间存在很大差异。使用Optosil(注册商标)的差异比使用Optocal的大。在义齿佩戴者中，Optocal和Optosil(R)之间的粉碎度差异大于有齿受试者。假牙佩戴者和有牙齿受试者之间的粉碎差异以及Optocal和Optosil(R)在两组内的粉碎差异在很大程度上是在不到20次的咀嚼行程中建立起来的。结果表明，选择的差异在很大程度上导致了粉碎的差异。由于Optocal似乎比Optosil(R)更容易咀嚼，因此在测量全口义齿佩戴者的咀嚼性能时，它可能比Optosil(R)更可取。
An experimental artificial test food with low fracture strength (Optocal) was compared with Optosil(R) with respect to the comminution during mastication by complete denture wearers and subjects with natural dentitions. The comminution of both test foods revealed large differences between the denture wearers and the dentate subjects. These differences were larger with Optosil(R) than with Optocal. The differences in comminution between Optocal and Optosil(R) were larger in the denture wearers than in the dentate subjects. The differences in comminution between the denture wearers and the dentate subjects as well as the differences in comminution between Optocal and Optosil(R) within each group were largely established in less than 20 chewing strokes. The results indicate that differences in selection contributed substantially to the differences in comminution. Since Optocal appeared to be much easier to chew than Optosil(R), it may be preferred to Optosil(R) for measuring masticatory performance in complete denture wearers.
