摘　　要：目的比较语音法确定的下颌位置与牙尖交错位之间的关系,检验语音法的稳定性。方法选取健康志愿者19名,记录发/xi/、/er/、/yi/、/ci/、/mi/、/ni/、/ri/共7个音时的下颌位置,比较该位置与牙尖交错位在水平面的前后和左右方向上的关系。采用多因素方差分析法分析不同个体和发音音素对发音时下颌位置变化的影响。结果 1)研究对象在发7种发音时的下颌位置均位于牙尖交错位的前方,测量的所有下颌位置,82%在左右方向上位于牙尖交错位0.5 mm范围之内。2)不同发音音素所确定的下颌位置,在前后方向上的差异不明显,而不同研究对象所确定的下颌位置在前后方向上的差异明显,且与研究对象本身正中关系位与牙尖交错位之间的距离有正相关性。结论应用7种发音时,下颌位置均位于牙尖交错位的前方;同一名研究对象发音时的下颌位置稳定。Objective The aim of this study was to compare the mandibular position when speaking with the intercuspal position and to check the stability of phonetics when determining the horizontal jaw relation in healthy adults. Methods A total of 19 healthy volunteers were recruited. Seven Chinese letters, namely,/xi/,/er/,/yi/,/ci/,/mi/,/ni/, and/ri/, were chosen in the test. O-bite was used to record the mandibular position when speaking these letters. A full-adjusted articulator was used to find the mandibular position during speech, and the mandibular position was measured using a vernier caliper. The mandibular position during speech with intercuspal position was compared in both anterior-posterior and left-right directions of the horizontal plane. Multi-factor analysis of variance was conducted fbr the statistical analysis of the effect of objects and letters on the mandibular position. Results 1） The mandibular position was in front of the intercuspal occlusion position when speaking all seven letters, and almost no deviation was observed in the left and right directions （the mandibular position value of 82% was in the range of 0.5 mm）. 2） Different objects had different mandibular positions during speech, whereas different letters did not. The distance between the centric relation position and the intercuspal position had a positive correlation with the range of the mandibular position during speech. Conclusion The mandibular position was in front of the intercuspal position when speaking all seven words in the test. In the same object, the mandibular position was stable during speech.
