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.

舌头的错误被认为是错误结咬的可能原因，但是在日常活动期间，没有最佳系统来衡量其长时间的位置和压力。制造了无线遥测器系统，以测量长时间的开放咬合患者的舌头位置和压力。LIP和舌压由高灵敏的微压仪表测量，这些压力仪嵌入了上下牙科拱门上的薄塑料板中。倾斜度计评估头部姿势。数据是由无线信号从便携式处理器传输到数据输入系统的，因此受试者不需要留在实验室并能够四处走动。获得的结果如下：l）稳定案例处的舌头接触不会改变或术后术后减少。另一方面，不稳定的病例显示出来。（p <0.01）2）接受骨切除术的患者的舌接触在术后没有变化。3）大大的头部屈曲对应于舌头的舌头和压力。（p <0.0 1）4。（p <0.0 1）4）张开的咬合案例的压力略低于正常的接触。（p <0.05）新开发的无线遥测器系统可用于检测日常活动中的舌接触和压力很有用。结果表明，与牙齿的接触和压力可能是在正交手术后保持良好阻塞的重要因素之一。
