问题 单项选择题 B1型题

全口义齿基托需缓冲的区域是()

A.后堤区

B.远中颊角区

C.上颌牙槽嵴顶

D.下颌牙槽嵴顶

E.下颌舌骨嵴

答案

参考答案:E

解析:题1:正确答案是E。此题考查的是无牙颌的解剖标志和无牙颌功能性分区(缓冲区)。下颌舌骨嵴为下颌后部牙槽嵴舌侧的骨性隆起,此处黏膜薄,易产生压痛,因此基托在此处应进行缓冲,避免黏膜压迫。上颌后堤区和下颌远中颊角区属于边缘封闭区,牙槽嵴顶属于主承托区,这些部位的义齿基托均不需要缓冲。题2:正确答案是A。此题考查对全口义齿后堤的了解。上颌总义齿腭侧基托后缘在后堤区(前后颤动线之间)组织面突起成后堤。义齿就位后,后堤压紧黏膜,达到后缘封闭的作用。下颌远中颊角区虽也属于边缘封闭区,但此处的封闭作用需靠黏膜反折的包裹作用,基托不能压迫黏膜。基托在主承托区牙槽嵴顶应与黏膜密合,但不能压紧。下颌舌骨嵴属于缓冲区,基托组织面需缓冲而不是压紧。
