全口义齿初戴前后辅音第2共振峰频率与带宽的变化

The change of F2 and B2 in patients with complete denture

目的:研究全口义齿初戴前后的语音适应效果。方法:应用计算机语音分析系统,测量30例全牙列缺失患者在全口义齿初戴前、初戴时及初戴后1、2、4、8周,/zi/、/ci/、/si/的第2共振峰及带宽。结果:辅音第2共振峰及其带宽值在义齿初戴时与义齿初戴前相比,有显著性差异。结论:全口义齿初戴后的语音适应过程呈规律性。计算机语音分析系统可对全口义齿初戴前后患者语音变化特征进行定量分析,对临床修复有较好的指导意义。

PURPOSE: To study the clinic adaptive effect of speech articulation of patient with complete denture. METHODS: The sensitive utterance study was /zi/,/ci/,/si/, which was input into CSL directly before and after patient's restoration at the beginning, then at 1week, 2weeks, 4weeks and 8weeks, B2 of the utterance of 30 edentulous patients were measured by the computer. RESULTS: There were significant differences in F2 and B2 before and after patient's restoration. CONCLUSION: There is a definite regularity of speech articulation after restored with complete denture. CSL helps us to analyze speech articulation by visual accessing and provides basic theory of evaluation in clinical dental prosthetics.
