The classic maxillary full denture covers the whole palate, preventing the tongue from touching the denture base tissues itself. Thus, it has deleterious effects on cortical brain function and the ability to understand spoken language.
This study aimed to determine the effect of anterior palatal surface modifications of the complete denture on speech intelligibility oral perception and cortical brain function activity.
This study compared the speech clarity, oral discernment, and cortical mind capability activity of complete denture wearers in three study groups: a) complete denture wearers with a small opening (SO) in the maxillary front palatal base; b) complete denture patients who wear regular complete denture; c) complete denture patients who did not wear complete denture; and d) complete denture patients who wear a functionally contoured modified palate (FCMP). Patients with no teeth at all underwent four phases of testing to assess their cognitive abilities and speech quality (pitch and volume). In the first phase, partial dentures were used. During phase 2, a conventional full denture was inserted. In the third phase, a palatal base denture was functionally altered. In phase 4, dentures with a little aperture at the front of the palatal base were used. Results The values of pitch and intensity of sound in category A with FCMP modification I were 180.76 ± 24.12 and 73.27 ± 9.74, respectively. On the other hand, the values of pitch and intensity of sound in category B with FCMP modification I were 185.41 ± 27.29 and 73.91 ± 8.31, respectively. The values of pitch and intensity of sound in category A with SO modification II were 188.52 ± 21.11 and 76.13 ± 5.21, respectively. On the other hand, the values of pitch and intensity of sound in category B with SO modification II were 194.59 ± 24.02 and 75.21 ± 6.12, respectively. The findings for values of pitch and intensity were statistically significant among the four phases (p < 0.001). The highest speech intelligibility and cortical brain function were observed in phase 4 in both categories A and B, with the highest scores by experts of 3.21 and 3.42, respectively. ConclusionBased on the findings of this in vivo investigation, it can be concluded that using modified dentures (modification types I and II) following denture installation improves speech intelligibility, oral perception, and cortical brain function activity.
传统上颌全口义齿覆盖整个腭部，阻止舌头接触义齿基托组织本身。因此，它对大脑皮质功能和语言理解能力有有害影响。
本研究旨在确定全口义齿腭前部表面改良对语音清晰度、口腔感知和大脑皮质功能活动的影响。
本研究比较了三个研究组中全口义齿佩戴者的语音清晰度、口腔辨别能力和大脑皮质功能活动：a）上颌前部腭基托有小开口（SO）的全口义齿佩戴者；b）佩戴常规全口义齿的全口义齿患者；c）未佩戴全口义齿的全口义齿患者；d）佩戴功能性轮廓改良腭（FCMP）的全口义齿患者。无牙患者接受四个阶段的测试，以评估他们的认知能力和语音质量（音高和音量）。在第一阶段，使用局部义齿。在第二阶段，插入传统全口义齿。在第三阶段，对腭基托义齿进行功能改变。在第四阶段，使用腭基托前部有小孔的义齿。结果FCMP改良I类中A类声音的音高和强度值分别为180.76±24.12和73.27±9.74。另一方面，FCMP改良I类中B类声音的音高和强度值分别为185.41±27.29和73.91±8.31。SO改良II类中A类声音的音高和强度值分别为188.52±21.11和76.13±5.21。另一方面，SO改良II类中B类声音的音高和强度值分别为194.59±24.02和75.21±6.12。音高和强度值在四个阶段之间的差异具有统计学意义（p<0.001）。在A类和B类的第四阶段观察到最高的语音清晰度和大脑皮质功能，专家给出的最高分数分别为3.21和3.42。结论基于这项体内研究的结果，可以得出结论，在安装义齿后使用改良义齿（改良类型I和II）可提高语音清晰度、口腔感知和大脑皮质功能活动。
