OBJETO DE LA INVENCIÓNOBJECT OF THE INVENTION
La presente invención se refiere a una sonda periodontal que permite la medición de los niveles de inserción periodontal y periimplantario, así como los niveles de sangrado tras el sondaje e índice de placa, que son de interés para el estudio del nivel de salud gingival.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.
De forma más concreta se trata de un dispositivo óptico que permite que las mediciones realizadas a nivel de las bolsas periodontales y periimplantarias, sean realizadas por una cámara óptica intraoral, enviando las señales de la imagen captada a un ordenador que, en función de dichos datos, calcula los niveles de inserción periodontal y periimplantario, niveles de sangrado tras el sondaje e índice de placa.More specifically, 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.
ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION
Existe diferentes tipos de sondas o sensores periodontales, pudiendo citarse entre otras las que se describen las patentes europeas con números de solicitud 87302799, 88109785, y 91311206, como más recientes.There are different types of periodontal probes or sensors, including those described in European patents with application numbers 87302799, 88109785, and 91311206, as more recent.
No obstante mediciones periodontales con dispositivos de control se vienen haciendo desde hace largo tiempo. Concretamente en el año 1963 ard realiza una sonda con sensor de presión. Posteriormente Gabathuler y Hasell en 1971 utilizan sensores piezoeléctricos. En 1979 Vitek utiliza dispositivos basados en hojas helicoidales con medida electrónica. Polson en 1980 introduce una sonda de presión controlada para sin medida electrónica.However, periodontal measurements with control devices have been made for a long time. Specifically in 1963, ard made a pressure sensor probe. Later Gabathuler and Hasell in 1971 use piezoelectric sensors. In 1979 Vitek uses devices based on helical blades with electronic measurement. In 1980, Polson introduced a controlled pressure probe for no electronic measurement.
El primer dispositivo de medición electrónico de sondaje es realizado por Mombelli en 1986 pero no realiza una presión controlada, presentando problemas de limpieza y de manejo. El primer sistema que introduce un dispositivo informático para registrar los datos es realizado por Agudio en 1985 con una sonda de presión controlada pero no introducía datos de la medición. En tal sentido, aparecen en 1988 realizados por Gibbs dispositivos basados en la medición mecánica consistentes en un anillo que mueve dentro de una sonda calibrada, que indica la posición del mismo. Este sistema presenta el inconveniente de que es necesario la visualización de la zona de medición y conlleva un mayor tiempo de medición, (Sonda Florida) .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. In this sense, in 1988 Gibbs devices based on mechanical measurement consisting of a ring that moves within a calibrated probe, indicating its position, appear by Gibbs. This system has the disadvantage that it is necessary to visualize the measurement area and entails a longer measurement time, (Florida probe).
DESCRIPCIÓN DE LA INVENCIÓNDESCRIPTION OF THE INVENTION
La sonda periodontal de medición digital que la invención propone constituye un notable avance tecnológico en este campo, permitiendo mediciones de gran precisión, del orden de décimas de milímetro, y ello de una manera extraordinariamente rápida y con unos resultados plenamente fiables.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.
Para ello y a partir de cualquier sonda calibrada de medición periodontal, de las existentes en el mercado, dicha sonda se fija, a través de un mecanismo de sujeción, a un cilindro herméticamente cerrado y esterilizado, en el que se aloja una cámara óptica intraoral, de manera que dicha cámara queda situada a una distancia fija de la sonda periodontal calibrada y registra la imagen del nivel al cual la sonda ha sido introducida entre la pieza dentaria y la encía, enviando esta información a un sistema informático de medición.For this purpose and from any calibrated periodontal measurement probe, of those existing on the market, 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.
El sistema informático calcula, a través de la imagen recibida, la profundidad de la bolsa periodontal, permitiendo también, a partir de la imagen captada, medir los niveles de placa bacteriana y de sangrado que se producen tras el sondaje.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.

Para complementar la descripción que se está realizando y con objeto de ayudar a una mejor comprensión de las características del invento, se acompaña a la presente memoria descriptiva, como parte integrante de la misma, de una hoja única de planos en la que con carácter ilustrativo y no limitativo y en su única figura, se ha representado esquemáticamente y en alzado lateral, una sonda periodontal de medición digital realizada de acuerdo con el objeto de la presente invención, en situación de trabajo sobre la boca del paciente, de la que tan sólo ha sido representada una pieza dentaria y su correspondiente encía.To complement the description that is being made and in order to help a better understanding of the features of the invention, 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.
REALIZACIÓN PREFERENTE DE LA INVENCIÓNPREFERRED EMBODIMENT OF THE INVENTION
De acuerdo con un ejemplo preferente de realización práctica de la invención, la sonda periodontal de medición digital está estructurada a partir de una cámara óptica intraoral (1), de captación propiamente dicha, preferentemente materializada en un chip CCD y la circuitería electrónica accesoria al mismo. Esta cámara (1), de cualquier tipo convencional, puede ser tanto monocroma como de color. En el caso de utilizar una cámara monocroma, es posible obtener imágenes en color del diente mediante la inclusión de tres filtros de color, los cuales envían al ordenador tres imágenes. Mediante composición de esas tres imágenes, a través del software adecuado, es posible obtener una imagen color de la zona de captación.In accordance with a preferred example of practical embodiment of the invention, 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. In the case of using 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.
La cámara (1) se establece sobre un soporte tubular y cilindrico (2) , que la aloja en su interior, convenientemente estabilizada por cualquier mecanismo de fijación, como por ejemplo un mecanismo de presión o mediante rosca. El material del soporte (2) puede ser cualquier metal ligero, como por ejemplo una aleación de aluminio, o un material plástico. El soporte (2) se cierra frontalmente con la colaboración de una lente calibrada (3), cuyo diseño debe ser tal que permita obtener una imagen totalmente enfocada y nítida de la parte del diente y encía en la cual se inserta la sonda propiamente dicha (4) .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) .
Se ha previsto la posibilidad de adjuntar a la lente (3), convenientemente fijada también al soporte (2) , una boquilla a través de la que se inyecta aire a presión, con objeto de evitar el empañado de la lente (3) debido al aliento del paciente.The possibility of attaching to the lens (3), conveniently also fixed to the support (2), a nozzle through which air under pressure is injected is provided, in order to avoid fogging the lens (3) due to the patient breath
La pieza soporte (2) se fija a la sonda periodontal calibrada (4), de cualquier tipo convencional, a través de un mecanismo de fijación (5), mecanismo que debe permitir la inmovilización total del conjunto descrito.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.
Tal como anteriormente se ha dicho, la sonda periodontal calibrada (4) puede ser de cualquier tipo convencional, como por ejemplo una sonda comercial tipo "Williams", con la única salvedad de que debe incorpora marcas indicativas del nivel de inserción en la bolsa periodontal (6) .As previously stated, 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).
La cámara óptica (1) envía señales de las imágenes captadas en la boca del paciente a través de un cable de conexión (7) a un ordenador (8) , que recibe la imagen en formato digital. Una vez obtenida la imagen se procesa mediante un software adecuado, que realiza las siguientes funciones: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:
- Por un lado muestra en la pantalla (9) del ordenador el nivel de inserción periodontal y periimplantario. Dichos datos se calculan mediante un algoritmo que permite identificar en la imagen cada una de las estructuras presentes, es decir, la parte de diente captada, la parte de encía captada y el extremo activo de la sonda de inserción. Una vez identificadas dichas estructuras el ordenador calcula la longitud de la parte del extremo activo de inserción visible en la imagen y, dado que la longitud de la misma es ya conocida, deduce la parte del extremo que está insertada en la encía. Dicha función de cálculo es activada por el clínico mediante un pedal (10) accionado con el pie, disponiendo sin embargo en todo momento, en la pantalla (9), la imagen de captación de la sonda.- On the one hand it 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. Once these structures have been identified, 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.
- Por otro lado, el software indica también en la pantalla (9) el índice de placa del paciente. Dicho dato se calcula mediante un algoritmo que permite identificar en la imagen cada una de las estructuras presentes, es decir, la parte de diente captada, la parte de encía captada, y la parte de placa presente en el diente. Dicha placa se identifica gracias a la detección de cambio de color que presenta dicha placa. Mediante reconocimiento del área correspondiente a la placa, el software deduce el valor del índice de placa. Esta función la activa el usuario del sistema a través de comandos de menús presentes en el software.- On the other hand, 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. By recognition from the area corresponding to the plate, the software deducts the value of the plate index. This function is activated by the system user through menu commands present in the software.
- Finalmente, una vez sondado el paciente, el software es capaz de medir el nivel de sangrado. Dicho valor se calcula mediante un algoritmo que permite identificar en la imagen cada una de las estructuras presentes, es decir, la parte de diente captada, la parte de encía captada, y el área de sangrado del paciente. Mediante reconocimiento del área de sangrado, el software deduce el valor de dicha área. Esta función la activa el usuario del sistema a través de comandos de menús presentes en el software. - Finally, once the patient is probed, 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.
