Abstract
Dental implants, as a surgical option for obtaining firm anchoring of the prosthesis to the bone and tissue, are currently undergoing great technological advancements which comprise the use of surgical guides and kits with drills which, depending on the system and the brand used, require the use of adaptors for the drills, leading to a reduction in the space that allows the passage of the internal irrigation that is essential for preventing bone necrosis, due to the excess heat generated by friction between the instrument and the hard tissue. The invention of the present device, which belongs to the technical field of dental implants, has the main aim of providing an alternative to offer permanent, sufficient and necessary internal irrigation during dental implant surgery, regardless of the system and brand of the drills used.

DESCRIPCIÓN DETALLADA DE LA INVENCIÓN DETAILED DESCRIPTION OF THE INVENTION
Como puede apreciarse en los dibujos las mejoras al sistema de cirugía guiada para implantes dentales, objeto de la presente invención consta de piezas intermediarias y complementarias al sistema de irrigación de cualquier motor de fresado convencional y una guía quirúrgica digital impresa (en acrílico biocompatible) en 3D. As can be seen in the drawings the improvements to the system of guided surgery for dental implants, object of the present invention consists of intermediate parts and complementary to the irrigation system of any conventional milling motor and a printed digital surgical guide (in biocompatible acrylic) in 3D
En la figura (1) se observa un corte transversal de una guía quirúrgica (7) y los elementos que intervienen en el sistema de irrigación. In figure (1) a cross section of a surgical guide (7) and the elements involved in the irrigation system are observed.
En el sistema de cirugía guiada tradicional se requiere de un contra-ángulo (pieza de mano) (1) para realizar el fresado en el cual se colocan fresas (drills) con tope (2) para la preparación del lecho a implantar, dependiendo del sistema y marca utilizados es requerido o no, el empleo de reductores de diámetro (5) para las fresas (drills) (2), éstos se colocan en los anillos metálicos (sleeves) (6) de las guías quirúrgicas y se van intercambiando consecutivamente para aumentar el diámetro de la preparación. Al colocar los reductores (5) en los anillos (6) y posteriormente colocar la fresa (drill) (2) dentro de éste, se reduce el espacio que permite el paso de la irrigación (4) que proviene de la pieza de mano (1), evitando que llegue al sitio de la preparación (alveolo, lecho óseo), provocando que se genere calor
(Temperaturas mayores a 40°C) por la fricción entre el instrumento (2) y el hueso. Con el fin de evitar la insuficiente irrigación del lecho durante la preparación, se diseñó el siguiente sistema, el cual consiste en añadir a la vía principal de irrigación (10) proveniente del motor de fresado un distribuidor (8) en forma de "Y" que provea al contra-ángulo (pieza de mano) (1 ) la alimentación suficiente para irrigar por encima de la guía quirúrgica (7) durante el fresado y añadir ai diseño de la guía un tubo de irrigación (4) durante la etapa de diseño o posterior a la impresión a través de un tubo de acero inoxidable con diámetro de 1.65 mm y una longitud no mayor a 12 mm. La salida del tubo de irrigación (4) estará situada justo debajo del anillo (sleeve) (6) colocado en la guía quirúrgica (7) como puede apreciarse en la figura (3) y ei ángulo de inserción podrá variar de 0° a 50° partiendo de la línea perpendicular al ángulo de inserción de los anillos 6 evitando rebasar la altura de los mismos y permitir el fácil acceso al contra-ángulo (pieza de mano) (1). De manera ideal deberán estar colocados hacia el lado vestibular de las piezas dentarias. In the traditional guided surgery system a counter-angle (handpiece) (1) is required to perform the milling in which strawberries (drills) with a stop (2) are placed for the preparation of the bed to be implanted, depending on the system and brand used is required or not, the use of diameter reducers (5) for drills (2), these are placed in the metal rings (sleeves) (6) of the surgical guides and are exchanged consecutively to increase the diameter of the preparation. By placing the reducers (5) on the rings (6) and then placing the drill (drill) (2) inside it, the space that allows the passage of irrigation (4) that comes from the handpiece ( 1), preventing it from reaching the preparation site (socket, bone bed), causing heat to be generated (Temperatures greater than 40 ° C) due to friction between the instrument (2) and the bone. In order to avoid insufficient irrigation of the bed during preparation, the following system was designed, which consists of adding a "Y" shaped distributor (8) to the main irrigation path (10) from the milling motor. providing the contra-angle (handpiece) (1) with sufficient feed to irrigate over the surgical guide (7) during milling and add an irrigation tube (4) to the design of the guide during the design stage or after printing through a stainless steel tube with a diameter of 1.65 mm and a length of no more than 12 mm. The outlet of the irrigation tube (4) will be located just below the ring (sleeve) (6) placed in the surgical guide (7) as can be seen in figure (3) and the angle of insertion can vary from 0 ° to 50 ° starting from the line perpendicular to the angle of insertion of the rings 6 avoiding exceeding their height and allowing easy access to the contra-angle (handpiece) (1). Ideally they should be placed towards the vestibular side of the teeth.
Adicional al tubo de irrigación (4) es necesario añadir al diseño de la guía unas ventanas/salidas de expulsión (9) debajo del sleeve (6) en posición opuesta al tubo de irrigación (4) con el fin de evitar cualquier tipo de presión que pudiera generarse al inyectar el líquido en el sitio de la preparación, éstas pueden variar de 2 a 3 dependiendo de la zona en la que se esté trabajando (sector anterior, sector posterior) (Fig. 3) In addition to the irrigation tube (4), it is necessary to add to the guide design some ejection windows / outlets (9) under the sleeve (6) opposite the irrigation tube (4) in order to avoid any pressure that could be generated by injecting the liquid at the preparation site, these can vary from 2 to 3 depending on the area in which you are working (anterior sector, posterior sector) (Fig. 3)
El diseño del distribuidor (8) en forma de Ύ" consta de 3 conectores, 1 entrada y 2 salidas para dividir de manera uniforme el flujo de la irrigación
(10) proveniente del motor de fresado, en su interior cuenta con un bloque en forma de triángulo equilátero para evitar que se generen burbujas y/o turbulencias en su interior durante el flujo del líquido. Esta pieza es totalmente impresa en 3D del mismo material de la guía quirúrgica (7) y no es reutilizable. The design of the distributor (8) in the form of Ύ "consists of 3 connectors, 1 inlet and 2 outlets to evenly divide the irrigation flow (10) coming from the milling motor, inside it has an equilateral triangle-shaped block to prevent bubbles and / or turbulence in its interior during the flow of the liquid. This piece is fully 3D printed of the same material as the surgical guide (7) and is not reusable.
Las mangueras (3) necesarias para la interconexión de los componentes corresponden al calibre de las incluidas en el motor de fresado (1.65 mm de diámetro interno y 2 mm de diámetro extemo) y la longitud de las mismas varía de 8 cm a 15 cm entre el distribuidor (8) y el tubo de irrigación (4) del contra-ángulo (pieza de mano) (1) y de 10 cm a 20 cm entre el distribuidor y el tubo de irrigación (4) colocado en la guía quirúrgica. Una vez conectados y colocados todos los dispositivos de manera correspondiente, se procede a la preparación del lecho a implantar. Éste proceso se repite en cada uno de los anillos (sleeves) de la guía quirúrgica.
The hoses (3) necessary for the interconnection of the components correspond to the caliber of those included in the milling motor (1.65 mm internal diameter and 2 mm external diameter) and their length varies from 8 cm to 15 cm between the distributor (8) and the irrigation tube (4) of the contra-angle (handpiece) (1) and 10 cm to 20 cm between the distributor and the irrigation tube (4) placed in the surgical guide. Once all the devices are connected and placed in a corresponding manner, the bed to be implanted is prepared. This process is repeated in each of the rings (sleeves) of the surgical guide.
