根管的彻底清理是根管治疗成功的重要步骤之一。根管形态上有许多变异(沟嵴,死区及根管分枝、副根管等),使用手用根管锉难以触及,采取其它机械清创术也难以彻底去除软硬组织。针对上述问题,我们根据“CJY-1超声波洁牙机”的超声振动伸缩的工作原理,制作了一种超声锉应用于根管清创术,现介绍如下。一、超声锉的制作方法对“CJY-1超声波洁牙机”其它部件不需作任何改制,只是把该机换能器上的工作头调换下来,将手用根管锉柄端锉磨成与换能器上安装工作头孔直径大小即成超声锉(10号至15号一套共六支)。然后每支手用根
Root canal cleaning is one of the most important steps in the success of root canal therapy. Root canal morphology has many variations (ditch ridge, dead zone and root canal branch, root canal, etc.), the use of hand-held root canal file is difficult to reach, to take other mechanical debridement is also difficult to completely remove the soft and hard tissue. In response to the above problems, we based on the “CJY-1 ultrasonic scaler” ultrasonic vibration telescopic working principle, made an ultrasonic file applied to root canal debridement, are described below. First, the ultrasonic method of making the file “CJY-1 ultrasonic scaler” other components without any restructuring, but the work of the transducer on the machine swap, the hand file end of the file rasp And the transducer installed on the first hole hole size into an ultrasonic file (a set of 10 to 15 a total of six). Then use each hand root
