Dental Electrosurgical Units Whether you are a dental practitioner, a student, or an interested party, there are several things that you should know about dental electrosurgical units. Among the things you need to know are how to choose one and what to look for when buying one.

Multifrequency Traditionally, electrosurgical units operated at a fixed frequency. They are known as monopolar. This mode is a bit less efficient than the bipolar mode, but is more flexible in application. Electrosurgical units of the present invention operate at a higher frequency. This allows for deeper coagulation in the absence of necrosis. It also allows for superficial coagulation. It also allows for bipolar coagulation. The unit uses a feedback circuit to control the output voltage. This feedback circuit is coupled to the tank circuit. It is also coupled to a switching circuit. The output of the switching circuit is fed through a probe that is then applied to the patient. The feedback circuit provides a sampled output signal proportional to the output voltage. The amplitude of the output level varies according to the impedance of the patient, the depth of the cut, and the operating environment.
