The aim of this study was to evaluate speech sound production (SSP) in older edentulous patients provided with two different types of mandibular complete dentures (MCDs; conventional vs neutral zone).
Regarding the fact that complete dentures (CDs) affect SSP, it is unknown whether the set-up of the artificial teeth resulting from the neutral zone technique leads to a negative impact on SSP.
For 21 participants, a conventional MCD and a MCD using a modified neutral zone technique (neutral zone dentures) were fabricated. The SSP was described using a phonetically balanced text, which was recorded digitally and evaluated.
No significant difference in SSP was observed.
Within the limits of this study, it can be concluded that the application of the neutral zone technique in the mandible has no considerable impact on SSP.
本研究旨在评估佩戴两种不同类型下颌全口义齿（传统型与中性区型）的老年无牙颌患者的语音发音情况（SSP）。
鉴于全口义齿（CDs）会影响语音发音情况，尚不清楚中性区技术所形成的人工牙排列是否会对语音发音情况产生负面影响。
为21名参与者制作了一副传统型下颌全口义齿和一副采用改良中性区技术的下颌全口义齿（中性区义齿）。使用语音平衡文本描述语音发音情况，该文本进行数字录音并评估。
未观察到语音发音情况有显著差异。
在本研究的范围内，可以得出结论，下颌中性区技术的应用对语音发音情况没有显著影响。
