Description
Implante dental.Dental implant.
La presente invención hace referencia a un implante dental que presenta notables características de novedad y de actividad inventiva.The present invention refers to a dental implant that presents remarkable characteristics of novelty and of inventive activity.
La presente invención es fruto de los experimentos y trabajos realizados por el inventor con el objetivo de solucionar de manera óptima los diferentes problemas que se presentan en la realización de dichos implantes.The present invention is the result of experiments and work done by the inventor with the objective to optimally solve the different problems that present in the realization of said implants.
Como es sabido, los implantes dentales están destinados a quedar incorporados en la masa ósea del maxilar, presentando un terminal superior que sobresale y que está destinado a recibir las piezas de substitución en operaciones de incorporación de prótesis dentales.As is known, dental implants are intended to be incorporated into the maxillary bone mass, presenting an upper terminal that stands out and is intended to receive the replacement parts in operations of incorporation of dentures.
En el campo de la implantación dentaria existen diseños de implante que comprenden un cuerpo principal roscado o núcleo de fijación en el hueso de los maximales y plataforma o terminal superior para la conexión protésica de fijación del diente artificial con más de 25 años de existencia y utilización. No obstante, dichos implantes, pese a haber sido extensivamente utilizados, son susceptibles de mejoras en el campo de la biomecánica.In the field of dental implantation there are implant designs comprising a threaded main body or fixation nucleus in the bone of the maximales and platform or top terminal for prosthetic tooth fixation connection artificial with more than 25 years of existence and use. Do not However, these implants, despite having been extensively used, are susceptible to improvements in the field of biomechanics.
Dado que una función principal del terminal superior es recibir las piezas de substitución en operaciones de incorporación de prótesis dentales, resulta conocida en el sector la conveniencia de que las dimensiones del terminal superior sean de tipo normalizado. Así, por ejemplo, se denomina en el sector "universal" un terminal de forma exterior prismática hexagonal regular, con una anchura de lado de aproximadamente 2,70 mm, y una altura de prisma de unos 0,70 mm, siendo el valor del radio del cilindro que circunscribe el prisma hexagonal de aproximadamente 3,1185 mm.Since a main function of the terminal superior is to receive the replacement parts in operations of incorporation of dentures, is known in the sector the convenience of the upper terminal dimensions being of standard type. Thus, for example, it is called in the sector "universal" a hexagonal prismatic outer shape terminal regular, with a side width of approximately 2.70 mm, and a prism height of about 0.70 mm, the radius value being cylinder circumscribing the hexagonal prism of approximately 3.1185 mm.
Sin embargo, de acuerdo con las técnicas conocidas, dicho terminal no puede ser aplicado a todo tipo de implante. Cuando éste es aplicado a un implante con un diámetro del cuerpo de implante superior a los 3,75 mm resulta necesario ejercer una gran fuerza de roscado a través del terminal para introducir el implante, lo que se traduce en pérdidas de agarre del instrumento de roscado y/o la generación de daños en el terminal superior por un aumento de la presión de la herramienta sobre ésta y/o deslizamientos entre ambos elementos. Efectos similares se producen cuando se aumenta la longitud del cuerpo principal del implante.However, according to the techniques known, said terminal cannot be applied to all types of implant. When it is applied to an implant with a diameter of Implant body greater than 3.75 mm is necessary exert a great threading force through the terminal to introduce the implant, which results in loss of grip of the threading instrument and / or generating damage to the terminal superior by an increase in the pressure of the tool on it and / or landslides between both elements. Similar effects are produced when the length of the main body of the implant.
Además, este efecto puede producir una peor osteointegración del implante en el hueso por un mayor calentamiento del mismo.In addition, this effect may produce a worse osseointegration of the implant in the bone by a greater heating of it.
Es un objetivo de la presente invención dar a conocer implantes que presentan una facilidad de inserción mejorada, permitiendo, por ejemplo, la utilización de cuerpos de implante de un diámetro sustancialmente superior al del terminal superior.It is an objective of the present invention to give know implants that have an easy insertion improved, allowing, for example, the use of bodies of implant with a diameter substantially larger than the terminal higher.
Es otro objetivo de la presente invención dar a conocer implantes que permiten una fácil inserción con longitudes de implante grande.It is another objective of the present invention to give know implants that allow easy insertion with lengths of large implant
De acuerdo con las pruebas y estudios realizados por el inventor, la fuerza de inserción queda sustancialmente disminuida y la osteointegración notablemente mejorada, permitiendo en particular la utilización de terminales universales con diámetros de implante notablemente superiores, cuando el paso entre filetes de la zona roscada del cuerpo del implante es superior a 1 mm.According to the tests and studies carried out by the inventor, the insertion force is substantially decreased and osseointegration noticeably improved, allowing in particular the use of universal terminals with noticeably higher implant diameters, when the passage between Threads of the threaded area of the implant body is greater than 1 mm
Por lo tanto, la presente invención consiste en un implante dental, del tipo que comprende un cuerpo principal roscado con extremo de inserción en la masa ósea de forma general troncocónica y un terminal superior en el extremo opuesto receptor de los aditamentos de la prótesis dental con forma prismática regular, y se caracteriza porque la distancia entre los filetes de rosca contiguos en el cuerpo roscado del implante es superior a 1 mm.Therefore, the present invention consists of a dental implant, of the type comprising a main body threaded with end of insertion in the bone mass in general conical trunk and an upper terminal at the opposite end receptor of the prismatic shaped dental prosthesis attachments regular, and it is characterized because the distance between the fillets of contiguous thread in the threaded body of the implant is greater than 1 mm
De acuerdo con los estudios realizados por el inventor, esta característica técnica facilita la osteointegración del implante. Para aumentar este efecto, la invención podrá combinarse sinérgicamente con características conocidas del documento ES2211292, igualmente del presente inventor, en especial utilizando una forma de filete de rosca exterior asimétrica con base redondeada que carece de ángulos cortantes, existencia en el extremo de inserción de tres entradas equidistantes entre sí de efecto cortante. Como resultado de la adición de dichas características, se favorece la fabricación de implantes con una gran longitud de inserción y gran diámetro.According to the studies carried out by the inventor, this technical feature facilitates osseointegration of the implant To increase this effect, the invention may combine synergistically with known characteristics of the document ES2211292, also of the present inventor, especially using an asymmetric outer thread steak shape with rounded base that lacks sharp angles, existence in the insertion end of three equidistant inputs from each other from cutting effect As a result of the addition of said characteristics, the manufacture of implants with a Large insertion length and large diameter.
Como resultado de la combinación de éstas características, no sólo se mejora la osteoimplantación, sino que también se acortan los tiempos de intervención quirúrgica.As a result of the combination of these characteristics, not only osteoimplantation is improved, but Surgical intervention times are also shortened.
Una consecuencia especialmente ventajosa de la presente invención es que resulta posible utilizar la plataforma denomina habitualmente "universal" consistente en una plataforma de forma general prismática hexagonal regular con una anchura de cara de aproximadamente 2,70 mm y, también habitualmente, una altura de 0,70 mm con un cuerpo principal de implante o diámetro del núcleo de diámetro superior o superior a 4 mm, o incluso 4,5 mm, o incluso 5 mm.An especially advantageous consequence of the present invention is that it is possible to use the platform usually called "universal" consisting of a regular hexagonal prismatic general form platform with a face width of about 2.70 mm and also usually a height of 0.70 mm with a main body of implant or core diameter of diameter greater than or greater than 4 mm, or even 4.5 mm, or even 5 mm.
