上颌总义齿的后腭封闭,通常不是凭患者的肌肉功能,就是凭医生的经验制取的。通过选择性地移动软组织,使后腭封闭提供一种周围封闭,它可以: ——在说话和吞咽时保证组织紧密地接触,防止食物和碎屑进入义齿基托和其下的组织之间。——增加固位力和稳定性。——提供较厚的后缘,以补偿义齿基托在热处理时的收缩。——减少义齿后缘和舌背之间发生接触时的不适感。解剖标志: 前颤动线:此线位于硬腭上的不活动组
The maxillary denture posterior palate is closed, usually not with the patient's muscle function, is based on the doctor's experience system. Closing the posterior palate provides a peripheral closure by selectively moving the soft tissue, which can: - Ensure tissue intimate contact while speaking and swallowing, preventing food and debris from entering between the denture base and underlying tissue. - Increase retention and stability. - Provide a thick trailing edge to compensate for contraction of the denture base during heat treatment. Decreased discomfort when contact between the trailing edge of the denture and the dorsal tongue. Anatomical Marker: Anterior Fibrillation: This line is located in the inactive palate
