Definitions

  • the present invention relates to a periodontal probe that allows the measurement of the levels of periodontal and peri-implant insertion, as well as the levels of bleeding after probing and plaque index, which are of interest for the study of the level of gingival health.
  • it is an optical device that allows measurements made at the level of the periodontal and peri-implant bags, to be performed by an intraoral optical camera, sending the signals of the captured image to a computer that, depending on these data , calculates the levels of periodontal and peri-implant insertion, levels of bleeding after probing and plaque index.
  • the first electronic probe measurement device was made by Mombelli in 1986 but does not perform a controlled pressure, presenting problems of cleaning and handling.
  • the first system that introduces a computer device to record the data is made by Agudio in 1985 with a controlled pressure probe but did not enter measurement data.
  • This system has the disadvantage that it is necessary to visualize the measurement area and entails a longer measurement time, (Florida probe).
  • the periodontal digital measurement probe that the invention proposes constitutes a remarkable technological advance in this field, allowing very precise measurements, of the order of tenths of a millimeter, and this in an extraordinarily fast manner and with fully reliable results.
  • said probe is fixed, through a clamping mechanism, to a tightly closed and sterilized cylinder, in which an intraoral optical chamber is housed, so that said chamber is located at a fixed distance from the calibrated periodontal probe and It records the image of the level at which the probe has been inserted between the tooth and the gum, sending this information to a computerized measurement system.
  • the computer system calculates, through the image received, the depth of the periodontal pocket, also allowing, from the captured image, to measure the levels of bacterial plaque and bleeding that occur after probing.
  • this descriptive report is attached, as an integral part thereof, of a single sheet of plans in which for illustrative purposes and not limitative and in its only figure, a periodontal digital measurement probe performed in accordance with the object of the present invention, in a working situation on the patient's mouth, of which only a tooth and its corresponding gum has been represented.
  • the periodontal digital measurement probe is structured from an intraoral optical camera (1), of actual capture, preferably materialized in a CCD chip and the electronic circuitry accessory thereto .
  • This camera (1) of any conventional type, can be both monochrome and color.
  • a monochrome camera it is possible to obtain color images of the tooth by including three color filters, which send three images to the computer. By composing these three images, through the appropriate software, it is possible to obtain a color image of the capture area.
  • the chamber (1) is established on a tubular and cylindrical support (2), which houses it inside, conveniently stabilized by any fixing mechanism, such as a pressure mechanism or by means of a thread.
  • the support material (2) can be any light metal, such as an aluminum alloy, or a plastic material.
  • the support (2) is closed frontally with the help of a calibrated lens (3), whose design must be such that it allows to obtain a fully focused and clear image of the part of the tooth and gum into which the probe itself is inserted ( 4) .
  • the support piece (2) is fixed to the calibrated periodontal probe (4), of any conventional type, through a fixing mechanism (5), a mechanism that should allow total immobilization of the described set.
  • the calibrated periodontal probe (4) can be of any conventional type, such as a commercial type probe "Williams", with the sole caveat that it should include marks indicating the level of insertion in the periodontal pocket (6).
  • the optical camera (1) sends signals from the images captured in the patient's mouth through a connection cable (7) to a computer (8), which receives the image in digital format. Once the image is obtained, it is processed by an appropriate software, which performs the following functions:
  • the computer shows on the screen (9) of the computer the periodontal and peri-implant insertion level.
  • These data are calculated by means of an algorithm that allows each of the structures present to be identified in the image, that is, the part of the tooth captured, the part of the gum captured and the active end of the insertion probe.
  • the computer calculates the length of the part of the active insertion end visible in the image and, since its length is already known, it deduces the part of the end that is inserted into the gum.
  • Said calculation function is activated by the clinician by means of a pedal (10) operated with the foot, however, at all times disposing, on the screen (9), the image of capture of the probe.
  • the software also indicates on the screen (9) the plaque index of the patient.
  • Said data is calculated by means of an algorithm that allows to identify in the image each one of the structures present, that is, the part of the tooth captured, the part of the gum captured, and the part of the plate present in the tooth.
  • Said plate is identified by the color change detection that said plate presents.
  • the software deducts the value of the plate index. This function is activated by the system user through menu commands present in the software.
  • the software is able to measure the level of bleeding. Said value is calculated by means of an algorithm that allows identifying in the image each one of the structures present, that is, the part of the tooth captured, the part of the gum captured, and the area of bleeding of the patient. By recognizing the area of bleeding, the software deducts the value of that area. This function is activated by the system user through menu commands present in the software.

Abstract

En partant d'une sonde calibrée de mesure (4) existant sur le marché, l'invention concerne l'utilisation d'une chambre optique intraorale (1) fixée à un support (5) qui la place à une distance appropriée par rapport à la sonde calibrée proprement dite (4), ladite caméra (1) étant assistée par une lentille (3) qui, à son tour, assure une parfaite focalisation de la zone de travail de la sonde calibrée (4) à l'intérieur de la poche périodontale (6) du patient. La caméra (1) renvoie des images à un ordinateur (8) qui les traite de manière appropriée pour fournir des informations, à travers l'écran (9), relatives aux niveaux d'insertion périodontale et périimplantaire, de plaques bactériennes et de saignements après sondage, information présentant un intérêt pour l'étude du niveau de santé gingivale.
