戴义齿后对元音的影响主要是由于共鸣腔及舌位的变化使其共振峰的频率及宽度改变。对辅音的影响主要表现为擦音的高频能量减少。对语言影响最明显的是基托的厚度,铸造基托影响较小。在义齿基托上做出腭皱及切牙乳头,可帮助戴用者正常发音。对义齿的适应是由唇、舌、下颌运动作为一个整体共同调节完成的。戴入义齿后,口腔的语音功能将受到不同程度的影响。特别是给一些歌唱家、广播员、教师等工作上带来很多不便。因此,在义齿修复中,语音问题应同咀嚼功能及美观一样受到重视。材料和方法 Denture after the impact on the vowel is mainly due to changes in the resonance cavity and tongue to make the frequency and width of the formant changes. The impact on consonants is mainly manifested as the reduction of high frequency energy of fricatives. The most pronounced effect on language is the thickness of the base, which has less impact on the cast base. Palate on the denture base and palate denture nipples, can help the wearer normal pronunciation. The adaptation of the denture is accomplished by the joint movement of the lips, tongue and jaw as a whole. Wear dentures, the oral speech function will be affected to varying degrees.
