摘要： 垂直型食物嵌塞是指食物受咬合压力楔入邻间隙中,可对局部组织产生机械刺激并能引起细菌定植,从而引起嵌塞区域不适,甚至引起龋病和牙周疾病等。功能状态下,相邻两牙之间食物嵌塞通道的产生是食物嵌塞发生的关键环节,本文从生理状态下邻面接触关系开始,对垂直型食物嵌塞的发生机制进行讨论。

关键词: 垂直型食物嵌塞, 邻面接触区, 发生机制

Abstract: Vertical food impaction, defined as the forceful wedging of food into the interproximal space by chewing pressure, leads to mechanical stimulation and bacterial colonization, results in discomfort in food impaction areas, even caries and periodontal diseases. Food impaction channel between adjacent teeth during function is the key point in vertical food impaction. Focusing on physiological proximal contacts, we postulated the mechanism of vertical food impaction.

Key words: vertical food impaction, proximal contact, mechanism
