本文对面功能性接触面积的含义提出自己的见解,并提出一种用计算机图像处理系统测量总义齿(牙合)面功能性接触面积的方法,据此探讨其与咀嚼效率的关系。本文共测总义齿16例,结果表明(牙合)面功能性接触面积与咀嚼效率为显著的正相关关系。提示保证一定的(牙合)面面积是行使咀嚼功能的基础;(牙合)面不同区域在咀嚼中的作用各有侧重;减径时应以减支持尖为主,非支持尖应保持一定的宽度。
In this paper, we put forward our own opinions on the meaning of the functional contact area and propose a method to measure the functional contact area of the total denture with computer image processing system. In this paper, a total of 16 cases of total denture, the results show that (occlusal) functional contact area and chewing efficiency is a significant positive correlation. Tips to ensure a certain (occlusal) area is to exercise the basis of masticatory function; (occlusal) face different regions in the role of chewing each have emphasis; reducing should be based on the reduction of support tip, non-support tip should be maintained The width of
