发明名称 CONSTANT PRESSURE PERIODONTAL PROBE
摘要 A constant pressure periodontal probe (1) has a probing portion (3) and is connected to a handle (2) through a flexing joint (10). A backing portion (4) extends from the handle adjacent to but spaced away from the probe tip such that a gap (17) exists between the probing portion and the backing portion. As the probing portion is inserted into a pocket between the tooth and gum, the amount of resistance causes the probe portion to be displaced about the flexible joint, closing the gap between the probing and backing portions. When the probing portion contacts the backing portion, a constant insertion pressure has been reached and a reading is taken to determine the depth of the pocket. Utilizing such a constant pressure periodontal probe assures that each reading is taken at a set pressure, preventing damage to the gum tissue and assuring accurate readings.
