项目摘要

Malposition of the tongue is recognized as a possible cause of malocclusion, yet there has been no optimal system to measure its position and pressure for long hours during daily activities. A wireless telemeter system was fabricated in order to measure the tongue position and pressure in openbite patients for long hours in natural condition.Lip and tongue pressures were measured by the high sensitive micro-pressure gauges embedded into the thin plastic plates on the upper and lower dental arches. Head posture was evaluated by the inclination meter. The data were transmitted by the wireless signals from a portable processor to the data input system so that the subjects did not need to stay at the laboratory and were able to go around.The results obtained were as follows :l) Tongue contact at the stable case did not change or decreased post-surgically. On the other hand, unstable case showed increasing of it.(p<0.01)2) Tongue contact of the patient who received glossectomy did not change post-surgically.3) Great degree of head flexion corresponded to a larger contact and pressure of the tongue.(p<0.0 1)4) The pressure of open bite cases were slightly lower than that of normalocclusions5)The contact pressure was increased significantly by the applying of MFT.Especially, the pressure and contact were highly increased at the anterior palateregion.(p<0.05)A newly developed wireless telemeter system is useful to detect the tongue contact and pressure during daily activities. And the results suggest that the contact and pressure to the dentition might be one of the important factors to keep a good occlusion after the orthognathic surgery.

舌头错位被认为是咬合不正的可能原因，但目前还没有最佳系统来测量日常活动中长时间的舌头位置和压力。为了在自然条件下长时间测量开合患者的舌头位置和压力，制作了无线遥测系统。通过嵌入上下塑料薄板的高灵敏微压力计来测量嘴唇和舌头压力。牙弓。通过倾斜仪评估头部姿势。数据通过无线信号从便携式处理器传输到数据输入系统，这样受试者就不需要留在实验室，可以四处走动。得到的结果如下：l) 在马厩处的舌头接触术后病例没有变化或减少。另一方面，不稳定的病例则有所增加。(p<0.01)2) 接受舌切除术的患者的舌接触在手术后没有改变。3) 头部屈曲程度较大对应于舌接触和压力较大。 (p<0.0 1)4)开牙合病例的压力略低于正常咬合5)MFT的应用显着增加了接触压力。特别是在咬合处的压力和接触显着增加。前腭区域。（p<0.05）新开发的无线遥测系统可用于检测日常活动中的舌头接触和压力。结果表明，牙列的接触和压力可能是正颌手术后保持良好咬合的重要因素之一。
