摘要
目的：探讨坐位静息状态下舌肌对不同矢状向和垂直向位置舌力介导器的压力,以初步探索舌力介导器作为一种支抗方式的效用范围。方法：纳入19例个别正常牙合志愿者（男4名,女15名,年龄23~33岁）,分别个体化制作舌力介导器,矢状向测量选取正中线上对应于第二前磨牙远中、第一磨牙远中和第二磨牙远中3个部位,垂直向测量以舌位记录为参考零点,分别测量-3 mm、0 mm和3 mm这3个高度对应于第一磨牙远中处的压力。所用传感器型号为美国Honeywell公司生产的FSS1500NS,压力校验仪、监测仪以及分析软件由厦门福芯微电子科技有限公司设计制作。志愿者取坐位,测量舌体处于自然放松状态时的静息压力。使用Friedman test对矢状向及垂直向各组数据进行多样本比较的秩和检验,P〈0.05为差异有统计学意义。结果：在垂直向上,随着舌力介导器高度增加,压力逐渐增大（P〈0.001）,-3 mm、0 mm和3 mm高度的压力均值分别为105.83 Pa、167.75 Pa和254.25Pa。在矢状向上,压力由近中至远中逐渐减小（P〈0.001）,其均值分别为177.64 Pa、126.72 Pa和109.37 Pa。结论：舌肌在静息状态下对舌力介导器的压力随基托高度增加而增大,并且由近中至远中逐渐减小,但在实际应用时应综合考虑效果和舒适度,不宜过高和偏远中。
Objective： To measure the resting pressure of the tongue body on the sagittal and vertical dimensions of the tongue anchorage pad（ TAP）,and to investigate the proper position of TAP as an anchorage. Methods： Nineteen volunteers with individual normal occlusion（ 4 males and 15 females,age23-33 years） were recruited in the study. Individualized TAP was designed and made for each subject.On the sagittal dimension,the pressure along the midline at the level of the distal of the second premolar（ PM2）,the first molar（ M1） and the second molar（ M2） were measured. On the vertical dimension,pressures on TAPs with height of-3 mm,0 mm,and 3 mm were measured,with 0 mm standing for the reference point recorded by the tongue position record. The tongue resting pressure of the volunteers in the upright position was measured by miniature sensors（ FSS1500 NS,Honeywell,USA） embedded in TAP. Nonparametric analysis was applied with the significant level of 0. 05. Results： On the vertical dimension,the pressure obtained at the height of-3 mm,0 mm,and 3 mm were 105. 83 Pa,167. 75 Pa,and 254. 25 Pa,respectively（ P〈0. 001）. On the sagittal dimension,the pressure detected at the level of PM2,M1,and M2 were 177. 64 Pa,126. 72 Pa,and 109. 37 Pa,respectively（ P〈0. 001）. Conclusion： Tongue pressure rises significantly with the increase of TAP height. On the sagittal dimension,pressure decreases along the palatal midline in an anteroposterior direction. But in the clinical practice,we should also put comfort into consideration.
