义齿承托区的组织结构和解剖生理特点不同,对咀嚼压力的承受能力也不同,可分为主承托区、副承托区和缓冲区。一般在制作基托义齿的过程中都会考虑到这些特点,但因个体的差异,缓冲区的部位和范围不尽相同,而且每个患者对义齿压力的耐受性和适应能力也有差别,所以在义齿戴入后,常出现个别承托区负荷过重,粘膜受压疼痛,甚至有的形成溃疡,必须在复诊时加以磨除缓冲。为早期查明负荷过重区,减轻病人痛苦和就诊次数,我们在试戴总义齿或 Denture bearing area of ​​the organizational structure and anatomical and physiological characteristics of different, the ability to bear the pressure on the chewing are also different, can be divided into the main supporting area, supporting the area and the buffer zone. These characteristics are usually taken into account during the manufacture of the base denture. However, due to individual differences in the location and extent of the buffer zone and the tolerance and adaptability of each patient to the denture pressure, there is a difference Denture wear, often appear to support individual area overloaded, mucosal pressure pain, and even the formation of ulcers, must be removed at referral buffering. Early identification of overloaded areas, reduce patient pain and the number of visits, we try on total denture or
