DESCRIPCIÓNDESCRIPTION

Dispositivo, galga del plano oclusal, y procedimiento clínicos de determinación de la inclinación del plano oclusal de los dientes, de aplicación en clínicas de Odontología- Estomatología y Medicina-Cirugía y otras.Device, gauge of the occlusal plane, and clinical procedure for determining the inclination of the occlusal plane of the teeth, for application in dentistry-stomatology and medicine-surgery clinics and others.

Como es sabido y derivado del estado de la técnica actual, la inclinación del plano oclusal (plano oclusal: plano promedio establecido por las superficies oclusales e incisales de los dientes ("Glossary of Prosthodontics Therms" (GPT-6) de American Board of Prosthodontics, en J Prosthet Dent, enero 1994), por consenso general en Odontología, guarda relación con el estado de salud o enfermedad del aparato masticatorio de un sujeto; también, como describen Karkazis y Polyzois (J Prosthet Dent, 1991; 65, 258-64) la inclinación del plano oclusal guarda relación con la estética y función de las prótesis removibles. La inclinación del plano oclusal es importante en la dentición natural y en prótesis fijas, como se describió por Planas (Rehabilitación Neuro-Oclusal, 2a ed., Ed. Salvat, 1994) y por Santana y Mora (J Oral Rehab (en prensa)).As is known and derived from the state of the art, the inclination of the occlusal plane (occlusal plane: average plane established by the occlusal and incisal surfaces of the teeth ("Glossary of Prosthodontics Therms" (GPT-6) of the American Board of Prosthodontics , in J Prosthet Dent, January 1994), by general consensus in Dentistry, is related to the state of health or disease of the chewing apparatus of a subject; also, as described by Karkazis and Polyzois (J Prosthet Dent, 1991; 65, 258- 64) the inclination of the guard occlusal plane relative to the aesthetics and function of the removable prosthesis. the inclination of the occlusal plane is important in the natural dentition and fixed prostheses, as described by Planas (Rehabilitation Neuro-occlusal, 2nd ed. , Ed. Salvat, 1994) and by Santana and Mora (J Oral Rehab (in press)).

De lo descrito se deduce que conocer la situación del plano oclusal es imprescindible para emprender tratamientos rehab ilitadores dentales correctos, establecidos antes de abordar una rehabilitación o tratamiento oclusal.From what has been described it follows that knowing the situation of the occlusal plane is essential to undertake correct dental rehab illuminator treatments, established before addressing an occlusal rehabilitation or treatment.

Las observaciones expuestas son igualmente necesarias para tratamientos sobre dientes naturales y sobre prótesis implantosoportadas.The exposed observations are equally necessary for treatments on natural teeth and implant-supported prostheses.

Actualmente, para determinar y valorar la inclinación del plano oclusal de los dientes del sujeto en clínicas de Odontología-Estomatología, se puede recurrir a los métodos descritos por Williams ('Oclusal plañe orientation in complete denture construction", J Dent 1982;10:311-6), por Karkazis, Polizois y Zisis ("Relationship between ala tragus line and natural occlusal plañe. Implications in denture prosthodontics". Quintessence Int 1986;17:253-5), por Monteith ("A cephalometric method to determine the angulation of the occlusal plañe in edentulous patients". J Prosthet Dent 1985;54:81-7), o por Sloane y Cook ("A guide to the orientation of the plañe of occlusion". J Prosthet Dent 1953;3:53-65). El método de determinación de la inclinación del plano oclusal empleado por los autores anteriormente citados, consisten en un estudio radiológico. Pero presenta inconvenientes serios: esta técnica es invasiva, es decir que provoca daño en el paciente/sujeto, ya que las radiaciones ionizantes son siempre dañinas para el organismo humano, en mayor o menor grado; además, requiere diferir el diagnóstico, hasta la obtención de telerradiografías, de forma que debemos valorar los resultados mediante técnicas de visualización de las placas radiográficas; además, sólo da información promedio aproximada de los dos planos oclusales simultáneamente, no individualizando cada lado, que puede tener diferentes inclinaciones en un mismo sujeto o paciente. Otro procedimientos posible empleado en la actualidad para la valoración y medición de la inclinación del plano oclusal que venimos describiendo, se basa en la técnica indirecta del estudio de la oclusión con los modelos del paciente montados en un articulador mediante arco facial de transferencia del modelo superior. Consistente en obtener modelos buco-dentales del sujeto/paciente, introduciendo una sustancia e incrustándola en los dientes superiores ("impresión"), retirar la pasta y obtener positivado en material duro, como el yeso o resina, montarlos en un dispositivo "articulador" con toma y traslado de "arco facial", y empleo de fotografía o retícula sobrepuesta para ver la situación de los dientes y plano oclusal.Currently, to determine and assess the inclination of the occlusal plane of the subject's teeth in dentistry-stomatology clinics, the methods described by Williams can be used ('Occlusal plañe orientation in complete denture construction', J Dent 1982; 10: 311 -6), by Karkazis, Polizois and Zisis ("Relationship between ala tragus line and natural occlusal plañe. Implications in denture prosthodontics". Quintessence Int 1986; 17: 253-5), by Monteith ("A cephalometric method to determine the angulation of the occlusal plañe in edentulous patients ". J Prosthet Dent 1985; 54: 81-7), or by Sloane and Cook (" A guide to the orientation of the plañe of occlusion ". J Prosthet Dent 1953; 3: 53-65 ). The method of determining the inclination of the occlusal plane used by the aforementioned authors, consists of a radiological study. But it has serious drawbacks: this technique is invasive, that is, it causes damage to the patient / subject, since ionizing radiation is always harmful to the human organism, to a greater or lesser extent; In addition, the diagnosis needs to be deferred, until obtaining teleradiographs, so that we must assess the results by means of visualization techniques of the radiographic plates; In addition, it only gives approximate average information of the two occlusal planes simultaneously, not individualizing each side, which may have different inclinations in the same subject or patient. Another possible procedure currently used for the assessment and measurement of the inclination of the occlusal plane that we have been describing, is based on the indirect technique of the study of occlusion with the patient models mounted on an articulator by means of a facial arc transfer of the upper model . Consisting of obtaining oral-dental models of the subject / patient, introducing a substance and embedding it in the upper teeth ("impression"), removing the paste and obtaining positivity in hard material, such as plaster or resin, mounting them in an "articulator" device with taking and transfer of "facial arch", and use of superimposed photography or reticle to see the situation of the teeth and occlusal plane.

Este último procedimiento presenta los inconvenientes de que es necesario invertir un tiempo de personal altamente cualificado (que puede oscilar de 2 a 4 horas) y de materiales de impresión (yesos, etc). Por lo tanto, la obtención de estos datos se dilata en el tiempo (no es inmediata) elevándose indirectamente los costes del tratamiento.This last procedure has the disadvantages that it is necessary to invest a time of highly qualified personnel (which can range from 2 to 4 hours) and of printing materials (plasters, etc). Therefore, the collection of these data is delayed over time (not immediately) indirectly raising the costs of treatment.

La invención que presentamos consiste en un dispositivo y un procedimiento de utilización del mismo, permiten determinar la inclinación del plano oclusal de los dientes del sujeto/paciente superando los inconvenientes que plantean las técnicas y métodos descritos anteriormente en el sentido de reducir los tiempos y los costes necesarios para obtener los valores del ángulo del plano oclusal eliminando los riesgos derivados de las radiaciones y/o evitando maniobras molestas, costosas y que requieren invertir tiempo. Es además un instrumento fácil de construir y barato. La técnica es muy simple para un profesional medio y de fácil aplicación.The invention that we present consists of a device and a method of using it, allow to determine the inclination of the occlusal plane of the teeth of the subject / patient overcoming the inconveniences posed by the techniques and methods described above in the sense of reducing times and costs necessary to obtain the values of the angle of the occlusal plane eliminating the risks derived from the radiation and / or avoiding annoying, expensive maneuvers and that require to invest time. It is also an easy instrument to build and cheap. The technique is very simple for an average professional and easy to apply.

El dispositivo, galga del plano oclusal, consiste en un instrumento en forma de "U" de material rígido, en la que ambas ramas son diferentes en su forma y longitud, como puede observarse en la Fig. 1. La rama de longitud menor, rama intrabucal (RI) está dotada de dos soportes móviles y fijables que se pueden deslizar a lo largo de la misma, el soporte posterior SPThe device, gauge of the occlusal plane, consists of a "U" shaped instrument of rigid material, in which both branches are different in shape and length, as can be seen in Fig. 1. The branch of smaller length, intrabuccal branch (RI) is equipped with two movable and fixed supports that can slide along it, the rear support SP

(porque se introduce en la boca en la parte posterior) puede ser fijo y es el externo de la rama intrabucal RI de la galga. Esta misma rama intrabucal (RI) tiene otro soporte anterior SA (porque se introduce y coloca en la boca en la parte anterior) es el interno a la rama intrabucal RI de la galga; este soporte SA deslizable para adaptarse a la longitud individual de las arcadas dentarias, se coloca sobre las superficies dentarias de los dientes del maxilar superior; esto es, el SP sobre el segundo molar, u otro diente posterior. El soporte móvil(because it is inserted in the mouth at the back) it can be fixed and is the external of the intrabuccal branch RI of the gauge. This same intrabuccal branch (RI) has another anterior support SA (because it is introduced and placed in the mouth in the anterior part) is internal to the intrabucal branch RI of the gauge; this sliding support SA to adapt to the individual length of the dental arches, is placed on the dental surfaces of the teeth of the upper jaw; that is, the SP on the second molar, or another posterior tooth. Mobile support

SA se desplazará sin modificar su dirección, que será rectilínea, manteniendo la misma situación con respecto a la rama interna, sin girar, para apoyarlo sobre un diente anterior, como el canino o el primer premolar preferentemente, cuando éstos existen.SA will move without changing its direction, which will be rectilinear, maintaining the same situation with respect to the internal branch, without turning, to support it on an anterior tooth, such as the canine or the first premolar preferably, when they exist.

Se aplicará, insistimos, en dos puntos, uno anterior y otro posterior. El anterior es, generalmente, cúspide del canino por delante; el posterior, el segundo o primero molar definitivos (o segundo molar temporario), siempre de un mismo lado, que definen el plano oclusal.It will be applied, we insist, on two points, one before and one after. The former is, generally, cusp of the canine ahead; the posterior, the final second or first molar (or temporary second molar), always on the same side, that define the occlusal plane.

Los soportes móviles y deslizables SA y SP tienen la forma descrita en la figura 2, lo que permiten colocarse sobre la superficie de los dientes de forma estable. La altura de los soportes serán de 16 mm de alto, 6 mm de ancho y 5 mm de espesor, serán fíjables mediante un tornillo o tope sobre el eje de la rama RI. Como la rama interna tendrá un espesor de 3 mm aprox. en sentido cráneo caudal, en posición de medición en el sujeto, los soportes SA y SP sobresalen de la superficie de esta rama unos 5 mm. Este hecho es fundamental, ya que permite que los dientes, situados hacia el medio (de adelante a atrás, esto es, como ejemplo el I o molar o los premolares) que estuviesen sobresalientes en el plano oclusal, no impidan que los soportes puedan apoyarse en los dientes extremos de la arcada.The movable and sliding supports SA and SP have the shape described in figure 2, which allows to be placed on the surface of the teeth in a stable way. The height of the supports will be 16 mm high, 6 mm wide and 5 mm thick, they will be fixed by means of a screw or stop on the axis of the RI branch. As the internal branch will have a thickness of 3 mm approx. in the caudal skull direction, in the measuring position on the subject, the SA and SP supports protrude from the surface of this branch about 5 mm. This fact is fundamental, since it allows the teeth, located towards the middle (from front to back, that is, as an example the I or molar or the premolars) that were protruding in the occlusal plane, do not prevent the supports can rest in the extreme teeth of the arch.

PROCEDIMIENTOPROCESS

Los soportes móviles y deslizables SA y SP se colocan sobre la superficie de los dientes de forma estable. El anterior sobre canino u otro diente existente próximo, y el posterior sobre el segundo molar o sobre otro diente próximo, si aquél no existe. Se desplazarán ligeramente para adaptarse a la distancia exacta entre las cúspides o superficies dentarias que se han elegido, y se fija.The mobile and sliding supports SA and SP are placed on the surface of the teeth stably. The previous one on canine or another existing existing tooth, and the later one on the second molar or on another nearby tooth, if that does not exist. They will move slightly to fit the exact distance between the cusps or dental surfaces that have been chosen, and it is fixed.

La otra rama del dispositivo, rama extrabucal (RE), de sección poligonal, unida a la intrabucal y paralelas entre sí, permite visualizar desde el exterior (por paralelismo), la inclinación que adopta la rama RI. Esta RE, permite medir la inclinación del plano oclusal, respecto a puntos y/o lineas externos craneales, como los planos de Frankfort o de Camper (GPT-6, referencia citada en la DESCRIPCIÓN de la primera página de esta memoria), que pueden marcarse en la piel del sujeto respecto o sobre algún material que cubra la piel de esta zona; las aristas rectilíneas de la sección poligonal de esta rama RE, permiten medir la inclinación de ésta, con respecto a puntos anatómicos externos, con mejor rendimiento visual que si fuese redondeada. Lo que venimos describiendo se aplica sobre cada uno de los lados de la boca, individualizando cada valor del plano oclusal de cada lado del sujeto. Puede bastar la observación directa, para saber si coincide con alguna de estas lineas marcadas, o aplicar un goniómetro superpuesto, o marcando sobre un papel la linea que configura con su inclinación permitiendo obtener valores numéricos de los ángulos del plano oclusal de cada lado de cada sujeto, respecto a aquellos puntos o planos cefalométricos.The other branch of the device, extrabuccal branch (RE), of polygonal section, attached to the intrabuccal and parallel to each other, allows to visualize from the outside (by parallelism), the inclination that the RI branch adopts. This RE, allows to measure the inclination of the occlusal plane, regarding points and / or external cranial lines, such as the Frankfort or Camper planes (GPT-6, reference cited in the DESCRIPTION of the first page of this report), which may be marked on the subject's skin with respect to or on some material covering the skin of this area; the rectilinear edges of the polygonal section of this branch RE, allow to measure the inclination of this one, with respect to external anatomical points, with better visual performance than if it were rounded. What we have been describing applies to each side of the mouth, identifying each value of the occlusal plane on each side of the subject. Direct observation can be enough to know if it coincides with any of these marked lines, or apply an overlapping goniometer, or marking on a paper the line that configures with its inclination allowing to obtain numerical values of the occlusal plane angles of each side of each subject, with respect to those cephalometric points or planes.

La Fig. 3 muestra el procedimiento de utilización del dispositivo que se describe. Modo de realización: mediante un material rígido como el acero inoxidable, plástico, biomateriales, es decir cualquier material propio de uso en clínicas dentales o ingeniería, se configura una "U" (Fig. 1). La RI interna se dota de dos soportes o apoyos (fig. 2) que pueden reglarse y fijarse a diferentes distancias entre si, para que coincidan con las cúspides o superficies de los dientes o prótesis del sujeto que se estudia (Fig. 3). La separación entre los dos soportes podrá oscilar entre 1 cm y hasta 7 cm, aproximadamente longitud máxima de la arcada dentaria. La rama externa, más delgada (0,5 cm de longitud de lado de la sección aproximadamente, será de sección tipo poligonal, para que las lineas de las aristas permitan ver clara y rectilíneamente la dirección de éstas y compararlas con los planos faciales de Camper o Frankfort (Fig. 3). Fig. 3 shows the procedure for using the device described. Method of implementation: using a rigid material such as stainless steel, plastic, biomaterials, that is, any material used in dental or engineering clinics, a "U" is configured (Fig. 1). The internal IR is provided with two supports or supports (fig. 2) that can be regulated and fixed at different distances from each other, so that they coincide with the cusps or surfaces of the teeth or prostheses of the subject being studied (Fig. 3). The separation between the two supports may range between 1 cm and up to 7 cm, approximately the maximum length of the dental arch. The thinner outer branch (0.5 cm in length of the side of the section approximately, will be of polygonal type section, so that the lines of the edges allow to see clearly and rectilinearly the direction of these and compare them with Camper's facial planes or Frankfort (Fig. 3).
