      base].

AB  - 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 with 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 +/- 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.
