ESTADO DE LA TÉCNICA STATE OF THE ART
Los implantes dentales a los que se refiere el dispositivo son aquellos que son implantados en el hueso maxilar y/o mandibular mediante una operación quirúrgica, y los cuales presentan un cuerpo y una plataforma, esta última es la cual va a recibir y soportar la rehabilitación planificada. Se denominan implantes dentales a los elementos aloplásticos (sustancias inertes, extrañas al organismo humano) que se alojan en pleno tejido óseo o por debajo del periostio, con la finalidad de conservar dientes naturales o de reponer piezas dentarias ausentes. The dental implants to which the device refers are those that are implanted in the maxillary and / or mandibular bone through a surgical operation, and which have a body and a platform, the latter is the one that will receive and support the rehabilitation planned. Dental implants are called alloplastic elements (inert substances, foreign to the human body) that are housed in full bone tissue or below the periosteum, in order to preserve natural teeth or to replace missing teeth.
Durante los últimos años, se han producido avances tecnológicos y biológicos muy importantes en la Implantología, que han determinado que el número de pacientes tratados con este método sea cada vez mayor. Actualmente, las técnicas implantológicas brindan múltiples posibilidades de tratamiento con elevada predictibilidad de los resultados. Ello ha contribuido a ampliar el campo de la rehabilitación protésica. Para su realización, se exigen técnicas complejas del tipo multidisciplinario; sin embargo, su papel en la práctica clínica moderna está siendo muy destacado. During the last years, there have been very important technological and biological advances in implantology, which have determined that the number of patients treated with this method is increasing. Currently, implant techniques offer multiple treatment possibilities with high predictability of results. It has contributed to expanding the field of prosthetic rehabilitation. For its realization, complex techniques of the multidisciplinary type are required; however, its role in modern clinical practice is being very prominent.
Para poder efectuar la rehabilitación de dicho implante, es necesario realizar una toma de impresión obtenida de la boca del paciente utilizando dispositivos especiales hechos a medida, perforados en la zona del implante, haciendo uso de pines de transferencia para obtener una copia fidedigna de la posición del implante en boca y poder así, ser confeccionada la estructura rehabilitadora en el laboratorio. To be able to carry out the rehabilitation of said implant, it is necessary to take an impression obtained from the patient's mouth using special devices made to measure, drilled in the implant area, using transfer pins to obtain a true copy of the position. of the implant in the mouth and thus be able to make the rehabilitation structure in the laboratory.
La utilización de dispositivos especiales hechos a medida involucra una primera toma de impresión de la boca del paciente con un dispositivo estándar para luego ser confeccionado en el laboratorio el dispositivo especial hecho a medida con la perforación en la zona del implante. Este proceso tiene el inconveniente de tener que realizar una atención al paciente previo a la confección del dispositivo especial hecho a medida, junto a su vez de aumentar el costo de la atención para el paciente. De la misma manera, el hecho de realizar dispositivos especiales a medida no otorga la posibilidad de su reutilización, por lo que aumentan los costos para el dentista tratante. The use of special made-to-measure devices involves a first impression of the patient's mouth with a standard device, and then the special device made to measure with the perforation in the implant area is made in the laboratory. This process has the drawback of having to perform patient care prior to making the special custom-made device, as well as increasing the cost of care for the patient. In the same way, the fact of making special made-to-measure devices does not provide the possibility of their reuse, thus increasing costs for the treating dentist.

Presenta una disposición que permite la extracción de segmentos del dispositivo a través de tornillos anclados al cuerpo del dispositivo, permitiendo la abertura de éste. Sin embargo, su elevado costo de adquisición y su complejo sistema de utilización ha hecho difícil su masificación y utilización clínica. La solución propuesta en la presente solicitud se basa en el objetivo de establecer una copia fidedigna de la posición del implante en boca con la capacidad de disminuir el número de sesiones para el paciente junto con disminuir los costos efectivos tanto para el paciente como para el dentista tratante. In 2000, Bernard Guillaume and Jean Mazeirat devised a device for taking dental impressions with removable segments, the invention of which was patented in the United States on October 22, 2002 under patent number US 6468078. It presents an arrangement that allows the extraction of segments of the device through screws anchored to the body of the device, allowing the device to be opened. However, its high acquisition cost and its complex system of use have made its widespread and clinical use difficult.
