ABSTRACT:
This invention relates to a periodontal instrument and curettage method for separating and removing diseased granulation tissue from a periodontal cavity. The instrument is comprised of a periodontal curette affixed to a source of ultrasonic energy that drives the curette in an elliptical motion at an ultrasonic frequency. The instrument greatly reduces the physical effort and time required for periodontal curettage.
