对16名义齿佩戴者进行了总计1，472次咀嚼测试，以研究以下义齿因素对其咀嚼效率的影响：食物平台区域、颊面和舌面的轮廓以及金属插入物及其暴露的咬合高度。咬合标记的存在，无论是凹槽还是插入物的形式，在后牙上的牙齿，发现显着增加义齿佩戴者粉碎生胡萝卜的能力。两种类型的咬合标记，凹槽和插入物，被证明是同样有效地改善咀嚼性能。然而，金属嵌体减少后牙咬合面导致咀嚼性能显着降低与花生。前后尺寸的食物平台被发现对咀嚼性能没有影响。无论食物平台面积是否等于2、3或4颗后牙的面积，义齿佩戴者都能够以相同的效果咀嚼生胡萝卜和花生。
A total of 1,472 masticatory tests were conducted on 16 denture wearers to study the influence of the following denture factors on their chewing efficiency: the food platform area, the contour of the buccal and lingual surfaces, and metal inserts and their exposed occlusal height.The presence of occlusal markings, whether in the form of grooves or inserts, on posterior teeth was found to increase significantly the ability of denture wearers to comminute raw carrots. The two types of occlusal markings, grooves and inserts, were shown to be equally effective in improving chewing performances. However, a reduction in the subocclusal surface of posterior teeth with metal inserts resulted in significant reduction of masticatory performance with peanuts.The anteroposterior dimension of the food platform was found to have no influence on masticatory performance. The denture wearers were able to chew raw carrots and peanuts with equal effectiveness regardless of whether the food platform area was equal to that of 2, 3, or 4 posterior teeth.
