Description

Implante dental expansivo.Expansive dental implant

Objeto de la invenciónObject of the invention

El implante dental expansivo, objeto de la presente patente de invención trata de presentar un nuevo elemento en el campo de la cirugía odontológica ósea, reuniendo una serie de mejoras en su estructura que la dotan de propiedades suficientes para superar a los sistemas análogos convencionales existentes en el mercado en cuanto a su implantación.The expansive dental implant, object of the This invention patent tries to present a new element in the field of bone dental surgery, gathering a series of improvements in its structure that provide it with sufficient properties to overcome the conventional analog systems existing in the market in terms of its implementation.

Para ello se utiliza un tornillo canulado y roscado interiormente de forma parcial, el cual contendrá interiormente un segundo tornillo que efectuará un efecto expansivo en las secciones inferiores del tornillo exterior. Opcionalmente, el tornillo podrá ser fijo y no expansivo.For this, a cannulated screw is used and internally threaded partially, which will contain internally a second screw that will have an effect expansive in the lower sections of the outer screw. Optionally, the screw can be fixed and not expansive.

Antecedentes de la invenciónBackground of the invention

Existen precedentes a la presente invención desde el ámbito de la ingeniería de construcción en cuanto a la ejecución de puntales y empotramientos que utilizan un sistema parecido, hasta la propia industria quirúrgica en determinadas prótesis canuladas de manera que su sujeción, al ser injertadas en hueso, depende en gran medida del elemento interno que se introduce en el agujero pasante o cánula longitudinal de la prótesis.There are precedents to the present invention since the scope of construction engineering in terms of execution of struts and embedments that use a similar system, to the surgical industry itself in certain prostheses cannulated so that its support, when grafted into bone, depends largely on the internal element that is introduced into the through hole or longitudinal cannula of the prosthesis.

Descripción de la invenciónDescription of the invention

Mediante el implante dental expansivo, objeto de la presente patente de invención, se aportan una serie de mejoras que palian o en su caso eliminan todos los inconvenientes arriba mencionados.Through the expansive dental implant, object of The present invention patent provides a series of improvements that alleviate or in their case eliminate all the inconveniences above mentioned.

El primer avance que impulsa el implante dental expansivo, pasa por haber aportado una solución al particular campo de la cirugía ósea en su aplicación odontológica, donde hasta ahora no se ha integrado dicha idea como medio de implante, mediante el cual se consigue un mayor anclaje entre implante y hueso, disminuyéndose integralmente el tiempo de osteointegración.The first advance that drives the dental implant expansive, happens to have contributed a solution to the particular field of bone surgery in its dental application, where until now This idea has not been integrated as a means of implantation, through which achieves greater anchorage between implant and bone, the osseointegration time decreasing integrally.

El segundo avance que impulsa el implante dental expansivo, está basado enteramente en la constitución física del objeto de la invención, el cual consta de un tornillo roscado, con un taladro en su interior en sentido axial, dotando a dicho taladro axial de una rosca que alojará un vástago roscado que quedará en el interior del tornillo una vez efectuada la inserción.The second advance that drives the dental implant expansive, it is based entirely on the physical constitution of the object of the invention, which consists of a threaded screw, with a hole inside it axially, providing said hole  axial of a thread that will house a threaded rod that will remain in the inside the screw after insertion.

El tornillo se encuentra ranurado longitudinalmente con al menos dos ranuras de longitud variable finalizadas en un taladro transversal que disminuye la concentración de tensiones. Así mismo, en esa zona final existirá un orificio perpendicular a este taladro que permitirá la inserción de un nuevo elemento mecánico para garantizar la fijación del implante dental expansivo. Interiormente el taladro efectuado tiene un desarrollo inferior cónico de manera que tras roscarse dicho tornillo en un hueso, se introducirá el vástago interior de manera que, expandiendo la conicidad interior adaptándola a una forma cilíndrica, las secciones inferiores se expandirán exteriormente gracias a la permisión de las ranuras. Por tanto, obtenemos que a pesar de roscarse el tornillo al hueso, el hecho de expandirlo hará que los filetes inferiores de la rosca se adentren aún más en el hueso con lo que su adaptación y sujeción será muy alta. Además, su geometría no cilíndrica contrarresta los esfuerzos de torsión que inestabilizan los implantes ya existentes. Independientemente de estas mejoras, el tornillo, opcionalmente, puede tener una variante no expansiva.The screw is grooved longitudinally with at least two slots of variable length finished in a transversal drill that decreases the stress concentration. Likewise, in that final zone there will be a hole perpendicular to this hole that will allow the insertion of a new mechanical element to guarantee the fixation of the expansive dental implant. Inside the drill effected has a conical lower development so that after Thread said screw into a bone, the rod will be inserted interior so that, expanding the interior taper adapting it to a cylindrical shape, the lower sections are They will expand externally thanks to the allowance of the grooves. By Thus, we obtain that despite threading the screw to the bone, the expanding it will make the lower thread steaks get go deeper into the bone so that its adaptation and support It will be very high. In addition, its non-cylindrical geometry counteracts the torsion forces that destabilize existing implants. Regardless of these improvements, the screw, optionally, It can have a non-expansive variant.

La aplicación del objeto de la invención es variable dependiendo de la geometría del principio expansivo en cuanto al diámetro externo e interno, número y longitud de ranuras, conicidad interior y resto de parámetros, se realizará en función de la zona ósea dental en la que se implante.The application of the object of the invention is variable depending on the geometry of the expansive principle in as for the external and internal diameter, number and length of grooves, interior taper and other parameters, will be done in function of the dental bone area in which it is implanted.
