  • Dental drill sterilization through application of high amperage current
    Patent number: 6692692
    Abstract: The present invention involves a sterilization system for running high amperage current through a dental or medical handpiece to be sterilized thereby heating the handpiece to a point of sterilization. The system includes a controller, a high amperage current source, and a handpiece receptacle. The handpiece receptacle includes clamps to hold the handpiece in place and a temperature sensor to measure the temperature of the handpiece. The controller controls the amount of current supplied by the high amperage current source to the handpiece according to the temperature of the handpiece. After the handpiece has been at or above the sterilization temperature for the required period of time, the controller stops the flow of current to the handpiece.
