Multi-Measurment Periodontal Probe
US Patent:
5090902, Feb 25, 1992
Filed:
Mar 12, 1991
Appl. No.:
7/669069
Inventors:
J. Robert Lemon - Charlotte AR
William T. Evans - Batesville AR

Assignee:
Professional Dental Technologies, Corp. - Batesville AR
International Classification:
A61C 1904
US Classification:
433 72
Abstract:
A multi-measurement periodontal probe (5) has a probing portion (7) which utilizes a needle-like tip (8) to determine the depth of a periodontal pocket. The probe additionally has a measurement member (9) extending opposite to the needle-like tip. The measurement member has gradations or other markings for determining the distance between an occlusal tooth surface and the bottom of the periodontal pocket, at the same time that the depth of the periodontal pocket is determined from the gumline. The use of such a probe allows determining whether periodontal disease is progressing while eliminating the bias encountered with changes in the gumline which may occur as a consequence of periodontal disease. Utilizing such a probe assures that accurate readings are taken and improves the accuracy of the diagnosis of periodontal disease.
Constant Pressure Periodontal Probe
US Patent:
5112226, May 12, 1992
Filed:
Oct 25, 1990
Appl. No.:
7/603638
Inventors:
J. Robert Lemon - Charlotte AR

Assignee:
Professional Dental Technologies, Inc. - Batesville AR
International Classification:
A61C 1904
US Classification:
433 72
Abstract:
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.
