Abstract:
In HF-surgery the patient is part of the electric circuit. Often the surrounding of the patient and the dental surgeon himself are included in the electric circuit, especially if no neutral electrode is used. In the patients mouth metallic elements such as amalgam, gold crowns and other parts of metallic restorations influence the flow of the electric high frequency current, used for cutting and coagulating. Due to this very complex situation, sure and quick cutting without hazards for the patient is only possible, if the dentist understands the electro-physical principles of HF-surgery.
