本文报导应用超声波将充填糊剂输送入牙根管的操作方法。产生超声波的方法有电压发生器和磁伸缩发生器两种,后者经过磁伸缩的效应,由电能变为机械能产生超声频率的振动,这种振动可利用作为充填根管的动力。作者采用口腔科临床作牙龈麻醉的注射器一支(Carpule式),利用其二头针尖,一端插入盛有充填糊剂玻管的橡皮塞内,此玻管可供观察糊剂容量的高度,在轻微的压力下,充填糊剂由针尖的另一端流出。然后通
This article reports the use of ultrasound to fill paste delivery into the root canal operation method. There are two methods of generating ultrasonic wave: a voltage generator and a magnetostrictive generator, the latter of which undergoes the effect of magnetostriction to generate ultrasonic frequency vibration from electrical energy, and this vibration can be used as a power for filling the root canal. The author uses a clinical dental implants gingival anesthesia syringe (Carpule type), the use of its two tip, one end filled with filled paste glass tube rubber plug, the glass tube for observation paste height, in the Under slight pressure, the filling paste flows out from the other end of the needle tip. Then pass
