目的 通过分析患者配戴金属基托和树脂基托全口义齿后发音的计算机语音学参数,探讨上颌义齿基托对语音功能的影响.方法 选择42例无牙颌患者,分别制作纯钛金属基托义齿和树脂基托义齿,用计算机语音分析系统提取患者配戴义齿后发声母/x、sh、r、zh、ch、j、q/的第一强频集中区(first concentrated frequency area,CFA-1)频率值和/g、k、zh、ch、j、q/嗓音起始时间(voice onset time,VOT),以戴人金属基托义齿所得资料作为A组,以戴入树脂基托义齿所得资料作为B组.配对t检验分析两组差异,观察比较两组舌根塞音三维语图.结果 A组声母/x、sh、r、zh、ch、j、q/CFA-1频率值[分别为(3595±102)、(3089±104)、(1876±116)、(4078±116)、(3604±119)、(5432±118)、(4934±121)Hz]低于B组[分别为(3644±101)、(3280±88)、(1978±113)、(4214±193)、(3817±49)、(5478±158)、(5020±183)Hz],差异均有统计学意义(P<0.05).A组声母/zh、ch、j/VOT值[分别为(54.67±1.13)、(143.80±2.24)、(62.53±0.75)ms]大于B组[分别为(52.88±0.34)、(137.55±2.50)、(62.00±1.54)ms],差异均有统计学意义(P<0.05),提示A组舌尖舌面成阻部位比B组靠后;A组/g、k/VOT值[分别为(26.94±0.33)、(114.53±2.15)ms]小于B组[分别为(28.59±0.65)、(124.40±3.74)ms],差异均有统计学意义(P<0.05),提示A组舌根成阻部位比B组靠前.观察舌根塞音/g、k/三维语图发现,患者配戴树脂基托义齿时79%(33/42)在正常冲直条前约1 ms处出现冗余冲直条,而配戴金属基托义齿时相应三维语图无此现象.结论 选择纯钛金属基托义齿,可减少舌腭区基托厚度,有利于患者语音功能的恢复.
目的 通過分析患者配戴金屬基託和樹脂基託全口義齒後髮音的計算機語音學參數,探討上頜義齒基託對語音功能的影響.方法 選擇42例無牙頜患者,分彆製作純鈦金屬基託義齒和樹脂基託義齒,用計算機語音分析繫統提取患者配戴義齒後髮聲母/x、sh、r、zh、ch、j、q/的第一彊頻集中區(first concentrated frequency area,CFA-1)頻率值和/g、k、zh、ch、j、q/嗓音起始時間(voice onset time,VOT),以戴人金屬基託義齒所得資料作為A組,以戴入樹脂基託義齒所得資料作為B組.配對t檢驗分析兩組差異,觀察比較兩組舌根塞音三維語圖.結果 A組聲母/x、sh、r、zh、ch、j、q/CFA-1頻率值[分彆為(3595±102)、(3089±104)、(1876±116)、(4078±116)、(3604±119)、(5432±118)、(4934±121)Hz]低于B組[分彆為(3644±101)、(3280±88)、(1978±113)、(4214±193)、(3817±49)、(5478±158)、(5020±183)Hz],差異均有統計學意義(P<0.05).A組聲母/zh、ch、j/VOT值[分彆為(54.67±1.13)、(143.80±2.24)、(62.53±0.75)ms]大于B組[分彆為(52.88±0.34)、(137.55±2.50)、(62.00±1.54)ms],差異均有統計學意義(P<0.05),提示A組舌尖舌麵成阻部位比B組靠後;A組/g、k/VOT值[分彆為(26.94±0.33)、(114.53±2.15)ms]小于B組[分彆為(28.59±0.65)、(124.40±3.74)ms],差異均有統計學意義(P<0.05),提示A組舌根成阻部位比B組靠前.觀察舌根塞音/g、k/三維語圖髮現,患者配戴樹脂基託義齒時79%(33/42)在正常遲直條前約1 ms處齣現冗餘遲直條,而配戴金屬基託義齒時相應三維語圖無此現象.結論 選擇純鈦金屬基託義齒,可減少舌腭區基託厚度,有利于患者語音功能的恢複.

Objective To compare the phonetic parameters changes of titanium denture base materials to that of conventionally processed poly methyl methacrylate(PMMA)resin.Methods Forty-two edentulous patients were included in this study.Each patient received two sets of dentures.One of the upper denture was restored with titanium denture base,the other was restored witll conventional PMMA denture base.Consonant /x,sh,r,zh,ch,j,q/associated with place of articulation and manner of articulation were chosen and all of the processed acoustic specimens were stored at computerized speech lab(CSL).Model 4150 (KAY) for the first concentrated frequency area (CFA-1),voice onset time (VOT) and spectrogram were analyzed.Results The consonant articulation effect of denture base showed significant difference between the two type of dentures in the CSL.The consonant parameters(/x,sh,r,zh,ch,j,q/)CFA-1 of group A [(3595±102),(3089±104),(1876±116),(4078±116),(3604±119),(5432±118),(4934±121)Hz]was different from the one of group B[(3644±101),(3280±88),(1978±113),(4214±193),(3817±49),(5478±158),(5020±183)Hz](P<0.05).The consonant parameters VOT of/zh,ch,j/in group A[(54.67±1.13),(143.80±2.24),(62.53±0.75)ms]was different from those of group B[(52.88±0.34),(137.55±2.50),(62.00±1.54) ms](P<0.05).The consonant parameters VOT of/g,k/in group A [(26.94±0.33),(114.53±2.15)ms] was different from those of group B [(28.59 4-0.65),(124.40±3.74) ms](P<0.05).A redundant spike as it was located prior to the inherent spike could be observed in the/g,k/spectrogram of the PMMA denture base group.Conclusions Titanium denture base is recommended to provide a satisfying form of articulate position with thinner front Palate thickness of the denture base.CFA-1 and VOT based CSL are effective acoustic parameters for articulation testing after denture delivery.
