Más concretamente, el objeto de la invención es un dispositivo de captación de información para despliegue virtual que permite optimizar el procedimiento para la ubicación de los modelos de la dentadura del paciente de manera que la tarea de posicionamiento relativo de dichos modelos no requiera de elementos tales como arcos faciales ni articuladores físicos donde ubicar dicho modelo, sino que dicha ubicación se realiza mediante la simulación virtual en los CAD/CAM dentales o modelos tridimensionales de las dentaduras asistidos por ordenador, donde dicha ubicación óptima es posible gracias a la utilización de este dispositivo que permite la toma de referencias directas del paciente para el posicionamiento virtual de modelos. More specifically, the object of the invention is an information capture device for virtual deployment that allows optimizing the procedure for the location of the patient's denture models so that the relative positioning task of said models does not require such elements as facial arcs or physical articulators where to locate said model, but that location is made by virtual simulation in dental CAD / CAM or three-dimensional models of computer-assisted dentures, where such optimal location is possible thanks to the use of this device which allows direct patient referral for virtual positioning of models.
Antecedentes de la invención Background of the invention
Actualmente una de las necesidades que se manifiestan en el sector de la odontología es la realización de algunos procedimientos y su ensayo fuera de la boca del paciente por motivos técnicos, de comodidad, o para la previsión de los resultados, para lo que se precisa la utilización de una réplica mecánica del aparato masticatorio del paciente extemo a la boca del paciente. Currently, one of the needs that are manifested in the dentistry sector is the performance of some procedures and their test outside the patient's mouth for technical reasons, comfort, or for the forecast of the results, for which the use of a mechanical replica of the external patient's masticatory apparatus to the patient's mouth.
Para llevar a cabo dicha obtención del modelo mecánico de la dentadura del paciente, normalmente se utiliza modelos de yeso de las dentaduras, unos registros de cera u otro material para tomar la referencia de la posición relativa entre dentaduras superior e inferior, un arco facial o dispositivo de captación físico para la toma de referencias de posicionamiento y un articulador físico para posicionar los modelos dentales en la posición original de la boca del paciente y poder simular la función masticatoria y movimientos mandibulares derivados de la articulación real simulando la boca del paciente, para realizar las distintas operaciones, como por ejemplo el diseño de una prótesis dental. En los laboratorios dentales, en el caso típico del diseño de una prótesis dental, tradicionalmente se ha trabajado siguiendo la metodología convencional, por lo que mediante el arco facial físico se toman las medidas del paciente para ubicar la arcada dental superior o dentadura superior respecto al sistema craneal, se lleva dicho registro al articulador físico para la simulación, se posicionan los modelos de yeso en la posición correspondiente en el articulador físico y se diseñan las prótesis a mano, de modo que siendo riguroso con el procedimiento, los resultados obtenidos son resultados transferibles a la oclusión o cierre mandibular del paciente con pocos ajustes de la superficie de cierre de los modelos de la simulación. In order to carry out said obtaining of the mechanical model of the patient's denture, plaster models of the dentures, wax records or other material are normally used to take the reference of the relative position between upper and lower dentures, a facial arch or physical capture device for taking positioning references and a physical articulator to position the dental models in the original position of the patient's mouth and be able to simulate the masticatory function and mandibular movements derived from the real joint simulating the patient's mouth, to perform the different operations, such as the design of a dental prosthesis. In the dental laboratories, in the typical case of the design of a dental prosthesis, it has traditionally worked according to the conventional methodology, so that through the physical facial arch the patient's measurements are taken to locate the upper dental arch or upper denture with respect to the cranial system, this record is taken to the physical articulator for simulation, plaster models are positioned in the corresponding position in the physical articulator and the prostheses are designed by hand, so that being rigorous with the procedure, the results obtained are results Transferable to the occlusion or mandibular closure of the patient with few adjustments of the closure surface of the simulation models.
Sin embargo hace algunos años se introdujeron los sistemas CAD/CAM dentales que consisten en diseños tridimensionales asistidos por ordenador de los modelos dentales, lo que ha supuesto una mejora en varios aspectos del diseño, como puede ser la aplicación de nuevos materiales a dichos diseños, la automatización o reducción de la mano de obra o una mayor rentabilidad con mejor calidad del control. However, a few years ago, dental CAD / CAM systems were introduced, consisting of computer-assisted three-dimensional designs of dental models, which has led to an improvement in several aspects of the design, such as the application of new materials to these designs, automation or reduction of labor or greater profitability with better control quality.
Aun así, existen aspectos que deben ser mejorados en estos sistemas CAD/CAM, por lo que a día de hoy se continua investigando y se está progresando en el desarrollo y mejora de estos sistemas que suponen una reducción de costes y ofrecen un mejor resultado favoreciendo y eliminando dificultades en las operaciones de odontología y prostodoncia. Even so, there are aspects that must be improved in these CAD / CAM systems, so today research is continuing and progress is being made in the development and improvement of these systems that involve cost reduction and offer a better result favoring and eliminating difficulties in dentistry and prosthodontics operations.
Paralelamente a estos sistemas mencionados CAD/CAM, hace algunos años se desarrollaron los primeros articuladores virtuales: el articulador virtual "DentCam" de Kordass y el articulador virtual de Szentpétery, (de los que cabe destacar que hoy en día no se encuentran en el mercado ninguno de ellos) de manera que se pretendía reducir el coste dejando de utilizar los articuladores físicos al poder realizar sus funciones mediante simulación por ordenador, mediante el despliegue virtual de todos los elementos de la simulación, para simular los movimientos de la mandíbula humana, pudiendo registrarlos, mover las superficies dentales oclusales o de cierre (es decir las superficies de los dientes que establecen contacto entre sí al cerrar la dentadura o realizar la oclusión) digitalizadas entre sí, de acuerdo con esos movimientos y corregir las superficies oclusales digitalizadas permitiendo movimientos sin colisiones, donde la información obtenida se utiliza para corregir posteriormente las superficies dentales de cierre de las coronas y puentes fabricados con un sistema CAD/CAM. Parallel to these CAD / CAM mentioned systems, some years ago the first virtual articulators were developed: the Kordass virtual articulator "DentCam" and the Szentpétery virtual articulator, (of which it is worth noting that they are not currently on the market none of them) so that it was intended to reduce the cost by ceasing to use the physical articulators to be able to perform their functions by computer simulation, by virtual deployment of all the elements of the simulation, to simulate the movements of the human jaw, being able to register them, move the occlusal or closing dental surfaces (i.e. the surfaces of the teeth that make contact with each other when closing the denture or perform the occlusion) digitized with each other, according to those movements and correct the surfaces Digitized occlusals allowing movements without collisions, where the information obtained is used to subsequently correct the dental closing surfaces of crowns and bridges made with a CAD / CAM system.
Este desarrollo de los sistemas CAD/CAM para la simulación de modelos en cuanto a las novedades ofrecidas por los nuevos articuladores han supuesto un avance y han traído ventajas en aspectos cualitativos, en cuanto a que se realizan las tareas de manera más sencilla, fiable y precisa, pero han traído un aumento de costes considerable en tanto en cuanto a que la toma de información mediante escaneo de los modelos a simular requerían el posicionamiento de dichos modelos en el articulador físico previamente, por lo que es necesario montarlo manualmente, y posteriormente escanearlo. This development of CAD / CAM systems for the simulation of models in terms of the novelties offered by the new articulators has been an advance and has brought advantages in qualitative aspects, in that the tasks are performed in a simpler, more reliable and precise, but they have brought a considerable increase in costs in that the taking of information by scanning the models to simulate required the positioning of these models in the physical articulator previously, so it is necessary to mount it manually, and then scan it .
En la feria de International Dental Show celebrada en marzo de 2011 en Colonia se presentaron varios articuladores virtuales dentro de los sistemas CAD/CAM, como son los Ammán Girbach, Zfx, 3Shape, SmartOptics, EXOCAD y Zirkonzahn, los cuales todos precisan realizar el montaje de las modelos en un articulador físico y una vez ubicados, escanear los modelos montados en esa posición, tal y como se ha descrito previamente. In the International Dental Show fair held in March 2011 in Cologne, several virtual articulators were presented within the CAD / CAM systems, such as the Ammán Girbach, Zfx, 3Shape, SmartOptics, EXOCAD and Zirkonzahn, which all need to be assembled of the models in a physical articulator and once located, scan the models mounted in that position, as previously described.
Se ha presentado Solicitud de Patente para los sistemas ZirkonZahn y SmartOptics mencionados anteriormente, las cuales se encuentran en tramitación, con número EP- 2229913-A1 y DE-102008060504-A1 , registros que comprenden invenciones que precisan la utilización tanto del mencionado arco facial físico para la toma de referencias entre modelos superior e inferior y poder montar dichos modelos de escayola en articulador físico para escanear en esa posición, para finalmente ubicarlo en el articulador virtual. Patent Application has been filed for the ZirkonZahn and SmartOptics systems mentioned above, which are being processed, with number EP-2229913-A1 and DE-102008060504-A1, records that include inventions that require the use of both the mentioned physical facial arc for taking references between upper and lower models and being able to mount said plaster models in physical articulator to scan in that position, to finally place it in the virtual articulator.
El sistema propuesto de ZirkonZahn mencionado requiere introducir el articulador físico con los modelos montados al escáner para posicionar ambos modelos en el articulador virtual, y el sistema propuesto por SmartOptics requiere el posicionamiento de los modelos en los platos superior e inferior del articulador, y se colocan en esa posición en el escáner que tiene y reconoce la misma geometría que el articulador físico, por lo que se puede decir que no prescinde de articulador físico, puesto que está integrado en el escáner. Además, durante el International Dental Show 2011 , se mostraron los dispositivos Arcus Digma, Zebris y AXIOQUICK, capaces de registrar los movimientos mandibulares tridimensionales mediante ultrasonidos, aunque dichos dispositivos no permiten relacionar de forma directa los registros de información de la boca del paciente con los articuladores virtuales como el objeto de la invención sí permite, y además el uso de estos dispositivos implica una inversión económica considerable. The proposed ZirkonZahn system mentioned requires introducing the physical articulator with the models mounted to the scanner to position both models in the virtual articulator, and the system proposed by SmartOptics requires the positioning of the models in the upper and lower plates of the articulator, and they are placed in that position in the scanner that has and recognizes the same geometry as the physical articulator, so it can be said that it does not dispense with the physical articulator, since it is integrated in the scanner. In addition, during the International Dental Show 2011, the Arcus Digma, Zebris and AXIOQUICK devices were shown, capable of recording the three-dimensional mandibular movements by ultrasound, although these devices do not allow to directly relate the information records of the patient's mouth with the Virtual articulators as the object of the invention do allow, and also the use of these devices implies a considerable economic investment.
Por tanto, según lo expuesto anteriormente, las invenciones hasta ahora conocidas por el estado de la técnica realizan la función del objeto de invención, pero en ningún caso comprenden un dispositivo capaz de transferir directamente la ubicación de los modelos de la dentadura del paciente al articulador virtual directamente. Therefore, as described above, the inventions hitherto known by the prior art perform the function of the object of the invention, but in no case do they comprise a device capable of directly transferring the location of the denture models from the patient to the articulator. virtual directly.

Para poder realizar la toma de información del dispositivo ubicado en el paciente, se utiliza preferentemente una escáner externo, de manera que se ubican unos medios de recogida de información (11) que son preferentemente unas pegatinas que hacen objetivo de escaneo los puntos a los que van adheridas, que son preferentemente tres puntos de la cabeza del paciente y varios puntos del tramo circunferencial (7) el cual está diseñado para contener dichas pegatinas puesto que está preferentemente formado por una sucesión de caras (9) casi planas que forman un arco, de modo que el escáner externo recoge información tanto de la cabeza del paciente como del tramo circunferencial (7) el cual está unido a la cubeta (6), y por ende, a la dentadura del paciente, lo que permite obtener unas coordenadas de referencia (5) que son preferentemente unos ejes de coordenadas cartesianas x, y, z que son trasladadas a un sistema de diseño asistido por ordenador, como se puede apreciar en las figuras 1 , 2 y 5. In order to be able to take the information from the device located in the patient, an external scanner is preferably used, so that information gathering means (11) are located, which are preferably stickers that make scanning the points to which they are attached, which are preferably three points of the patient's head and several points of the circumferential section (7) which is designed to contain said stickers since it is preferably formed by a succession of almost flat faces (9) forming an arc, so that the external scanner collects information from both the patient's head and the circumferential section (7) which is attached to the cuvette (6), and therefore, to the patient's denture, which allows obtaining reference coordinates (5) that are preferably axes of Cartesian coordinates x, y, z that are transferred to a computer-aided design system, as can be seen in the figures flush 1, 2 and 5.
