Objectives : Prosthodontic treatments by large sized maxillary denture base extensively cover the palatal mucosa where mechanoreceptors are densely distributed. Covering the palatal mucosa with a denture base causes physiological and functional hindrances such as unpleasantness, gag reflex and poor recognition of the tongue. The aim of this study was to clarify inference of tongue pressure during swallowing by wearing palatal plate.Methods : Twenty one subjects (12 males and 9 females, mean age;25 years, age range;22-29 years) were investigated. All subjects gave their written informed consent to participate in this study prior to the experiments.Subjects were asked to sit upright in a dental chair in order to measure the maximum voluntary tongue pressure and the tongue pressure during swallowing were measured based on the method described by Hayashi et al. These pressures were recorded three times under two conditions : palatal mucosa completely covered using an experimental palatal plate and uncovered. For the maximum voluntary tongue pressure recordings, the subjects were instructed to compress a specially designed small balloon between the tongue and the anterior part of the hard palate for 7 seconds with their maximum voluntary tongue effort. To record tongue pressure during swallowing, the subjects were instructed to swallow 5 ml of gelatin drink, as naturally as possible with the balloon pre-placed between the tongue and the anterior part of the palate, and the peak value of tongue pressure during swallowing was recorded. Differences obtained were compared by using the paired-sample t-test (p<0.05).Results : When the results of maximum voluntary tongue pressure and the tongue pressure during swallowing were compared between the two conditions, significant difference wasn't observed.Conclusion : The maximum voluntary tongue pressure and the tongue pressure during swallowing didn't have influence, when the hard palate was covered by a palatal plate.

目的：上颌大面积义齿基托修复覆盖腭部粘膜，是机械感受器密集分布的部位。用义齿基托覆盖腭粘膜会引起生理和功能障碍，如不愉快、呕吐反射和舌头识别不良。本研究的目的是澄清推断的舌压力在吞咽过程中穿腭plate.Methods：21例（12男，9女，平均年龄25岁，年龄范围;22-29岁）进行了调查。所有受试者在实验前都签署了参加本研究的书面知情同意书。受试者被要求直立坐在牙科椅上，以测量最大自愿舌压，并根据Hayashi等人描述的方法测量吞咽期间的舌压。在两种条件下记录三次这些压力：使用实验腭板完全覆盖腭粘膜和未覆盖腭粘膜。对于最大自愿舌压记录，受试者被指示以其最大自愿舌努力压缩舌头和硬腭前部之间的特别设计的小气囊7秒。为了记录吞咽过程中的舌压，受试者被指示尽可能自然地吞咽5 ml明胶饮料，其中球囊预先放置在舌头和上颚前部之间，并记录吞咽过程中舌压的峰值。结果：两种情况下的最大自主舌压和吞咽时舌压比较，差异无显著性（P> 0.05）。结论：硬腭被腭板覆盖后，对最大自主舌压和吞咽时舌压无影响。
