近年来,口腔电外科学在国外发展较快,Oringer的专著牙科电外科学(Electrosurgery in dentistry)已在1975年发行第二版。美国已经成立牙科电外科学会(The American Academy of Dental Electrosurgery)〔1〕。本文限于篇幅,仅就电外科在牙体、牙髓病方面的应用作一介绍。一、牙科电外科治疗机简介牙科电外科治疗机由电源转换装置及振荡器组成。振荡器是供给口腔内各种手术所必须的电流。过去使用的是真空管治疗机,现在多为晶体管治疗机。由振荡器输出的射频电流有三种: 1.全修正电流FR:主要用于组织切割,
In recent years, oral electrosurgery has developed rapidly abroad. Oringer's monograph Electrosurgery in dentistry was released in 1975 in the second edition. The United States has set up the American Academy of Dental Electrosurgery [1]. This article is limited to space, only on the application of electrosurgery in the tooth, endodontics to make an introduction. First, the introduction of dental electrosurgical treatment machine Introduction Dental electrosurgical treatment by the power conversion device and oscillator components. Oscillators are the necessary currents for various procedures in the oral cavity. In the past is the use of vacuum tube therapy machine, now mostly transistor therapy machine. The RF current output by the oscillator has three kinds: 1. Full correction current FR: mainly used for tissue cutting,
