Several excellent devices have recently been developed to precisely record mandibular movement. However, these devices are not always suitable for use under certain conditions, such as during sleep, because they incorporate a face bow unit. We report here a newly developed, easy and convenient recording device that does not require the use of an instrument within the mouth. Instead, a subminiature pressure transducer is inserted between the outer surface of a fixation device in the external auditory meatus and the anterior cutaneous surface of the external auditory meatus. The fixation device was made using silicone impression material in the shape of the inner external auditory meatus. Following moulding, the material was cut in half and the parts were reconnected using a coiled spring. This method is based on a routine clinical method for palpating the external auditory meatus to observe condylar head movement. By comparing the results obtained using this device with those obtained using CADIAX, we confirmed that it is useful for recording the movement of the condylar head in routine clinical examinations.
最近已经开发出了几种用于精确记录下颌运动的优秀设备。然而，这些设备在某些情况下并不总是适用，比如在睡眠期间，因为它们包含一个面弓装置。我们在此报告一种新开发的、简单方便的记录设备，该设备不需要在口腔内使用仪器。相反，一个超小型压力传感器被插入到外耳道固定装置的外表面与外耳道前皮肤表面之间。固定装置是用硅橡胶印模材料制成外耳道内部形状。成型后，材料被切成两半，部件用螺旋弹簧重新连接。这种方法基于一种常规临床方法，即通过触诊外耳道来观察髁突头部的运动。通过将使用该设备获得的结果与使用CADIAX获得的结果进行比较，我们证实它在常规临床检查中对于记录髁突头部的运动是有用的。
