项目摘要

To perform the multilateral evaluation of the abnormal tongue movement, the relationship between mandibular movement, tongue muscle activities and the morphologies of the maxillofacial skeletal pattern, and the movement of tongue during swallowing were investigated.1. The distance and the inclination of protruding movements were associated positively with *ANB, overbite and overjet. The inclinations of both anteriorly and posteriorly opening paths were associated positively with *MP-SN, *MP-FH and negatively with S-N and A'-Ptm'. The sagittal area of MBM was associated positively with gonial angle and negatively with A'-Ptm', Cd-Go. The inclination of lateral guided movements was associated positively with overbite.2. Subjects who have burst in anterior temporalis and masseter during swallowing were larger in the short face group, while smaller in the long face group. Timing of the initial burst of genioglossus (GG) and digastricus (DI) during swallowing resulted that GG is ahead of DI in the short and average face groups, therefore, nearly same time in the long face group.3. Type of tongue dorsum movement : In normal swallowing subjects (group NS), there were two types of tongue dorsum movement at the ascending which were direct ascending (type U) or first descending (type D). There were three types after the ascending which were making a clear plateau (type 1), keeping the highest point shortly (type 2) and directly descending (type 3). Consequently, normal swallowing subjects were evaluated as four types of U-1, U-3, D-2 and D-3. Tongue thrusting subjects (group TT) were evaluated as D-2 and D-3.Height, duration and velocity of tongue dorsum movement were compared. No significant differences were seen in the highest point and descending velocity after the ascending. Ascending velocity was faster and duration at the plateau was longer in U-I, while they were slower and shorter in D-2 and D-3.

为了对异常舌运动进行多边评估，研究了下颌运动，舌头肌肉活动和上颌面骨骼模式的形态以及吞咽过程中舌头运动的关系。1。突出运动的距离和倾斜度与 *Anb，咬合和过度相关。前部和后方开口路径的倾向与 *mp-sn， *mp-fh呈正相关，并与s-n和a'-ptm'负相关。 MBM的矢状区域与Gonial角度呈正相关，并与A'-PTM'，CD-GO呈负相关。侧向引导运动的倾向与咬合成正相关。2。吞咽期间在前颞前和咬肌中爆裂的受试者在短脸组中较大，而在长脸组中则较小。吞咽期间Genioglossus（GG）和Digastricus（DI）的初始爆发的时机导致GG在短和平均面部组中领先于DI，因此在长脸组中几乎相同的时间。3。舌背运动的类型：在正常的吞咽受试者（NS组）中，上升时有两种类型的舌背运动，它们是直接上升（U型）或第一次下降（D型）。上升后有三种类型的，这些类型的高原（类型1），尽快保持最高点（2型）和直接下降（型3）。因此，将正常的吞咽受试者评估为四种类型的U-1，U-3，D-2和D-3。将舌头推力受试者（TT组）评估为D-2和D-3.舌背运动的持续时间和速度。上升后的最高点和下降速度，没有看到显着差异。上升速度更快，在U-I中，高原的持续时间更长，而在D-2和D-3中的速度较慢且较短。
