为了了解舌在咬合发展中的作用，我们用超声、X线头影测量和牙模检查了吞咽过程中舌运动与牙面形态之间的关系。测量了112名健康成年志愿者舌运动的持续时间、幅度和速度，并与他们的牙颌面形态进行了简单的相关分析。结果表明，吞咽时舌运动与颌面部形态有关，尤其是在最后阶段（伊利亚期）的运动幅度上，但在分析吞咽持续时间和吞咽速度时，相关性不明显。结果还表明，颌间垂直尺寸与舌运动的运动幅度呈显着正相关。此外，我们发现，随着吞咽时间的延长，牙弓长度增加。本研究表明，计算机辅助B+M模式的超声检查结合双探头扫描技术是一个有价值的工具，研究之间的关系，舌运动在吞咽和牙面形态。
To understand the role of the tongue in the development of occlusion, we examined the relationship between tongue movements during swallowing and dentofacial morphology with ultrasonography, cephalometric radiography, and dental casts. Duration, magnitude, and speed of tongue movements were measured in 112 healthy adult volunteers and compared with their dentofacial morphology with a simple correlation analysis. The results showed that the movements of tongue during swallowing are related to dentofacial morphology, especially in the motion magnitude of the early final phase (phase Ilia), but that few correlations are found when analyzing the duration and the speed of swallowing. The results also showed that the intermaxillary vertical dimension is significantly and positively correlated with the motion magnitude of the tongue movements. Furthermore, we found that arch length increased with prolonged duration of swallowing. This study showed that the computer-aided B+M mode of ultrasonography combined with the cushion-scanning technique is a valuable tool for investigating the relationship between tongue movements during swallowing and dentofacial morphology.
