The authors developed a new method to measure the occlusal contact area in complete denture by using the IBAS 2000 (Interactive Image Analysis System). The masticatory efficiency and functional occlusal contact area were measured and analysed for 16 cases of complete dentures. The results showed that the relation between occlusal contact area and masticatory efficiency was positive significantly and different region of occlusal contact area had its corresponding masticatory efficiency. It is indicated that a given occlusal contact area is necessary to satisfy the masticatory efficiency required. If the masticatory load is great the width of supporting cusp should be reduced and a definite width of nonsupporting cusp should be preserved for holding the food being masticated.
作者开发了一种新方法，通过使用IBAS 2000（交互式图像分析系统）来测量全口义齿的咬合接触面积。对16例全口义齿的咀嚼效率和功能性咬合接触面积进行了测量和分析。结果表明，咬合接触面积与咀嚼效率之间存在显著正相关，且咬合接触面积的不同区域具有其相应的咀嚼效率。这表明需要一定的咬合接触面积来满足所需的咀嚼效率。如果咀嚼负荷较大，应减小支持尖的宽度，并保留一定宽度的非支持尖以容纳正在咀嚼的食物。
