DISPOSITIVO DE FIJACION DEL FRAGMENTO MOVIL PARA TECNICAS DE DISTRACCION ALVEOLAR EN IMPLANTOLOG^A DENTALMOVING FRAGMENT FIXING DEVICE FOR ALVEOLAR DISTRACTION TECHNIQUES IN DENTAL IMPLANTOLOGY
OBJETO DE LA INVENCIONOBJECT OF THE INVENTION
La invencion, tal como expresa el enunciado de la presente memoria descriptiva, se refiere a un dispositivo de fijacion del fragmento movil para tecnicas de distraccion alveolar en implantologfa dental, la cual aporta una serie de ventajas y caracterfsticas estructurales y constitutivas, que se describiran en detalle mas adelante, que suponen una destacable novedad en el estado actual de la tecnica.The invention, as expressed in the statement of the present specification, refers to a device for fixing the mobile fragment for alveolar distraction techniques in dental implantology, which provides a series of structural and constitutive advantages and characteristics, which will be described in detail below, which represent a remarkable novelty in the current state of the art.
Mas en particular, el objeto de la invencion se centra en un dispositivo de fijacion del fragmento movil para tecnicas de distraccion alveolar en implantologfa dental que constituye un medio de fijacion auxiliar para llevar a cabo dicha fijacion y que consiste en un elemento de acero o titanio en forma de grapa que abraza el fragmento oseo superior o de transporte al casquillo superior del distractor alveolar para conseguir una fijacion adicional y evitar que se desplacen independiente uno de otro en caso de perdida de anclaje mecanico de las espiras de dicho casquillo superior con respecto al fragmento oseo superior movil.More particularly, the object of the invention is centered on a device for fixing the mobile fragment for alveolar distraction techniques in dental implantology that constitutes an auxiliary fixing means for carrying out said fixation and consisting of a steel or titanium element. in the form of a staple that hugs the upper bone or transport fragment to the upper socket of the honeycomb distractor to achieve an additional fixation and prevent them from moving independently of each other in case of loss of mechanical anchoring of the turns of said upper bush with respect to the mobile upper bone fragment.
CAMPO DE APLICACION DE LA INVENCIONFIELD OF APPLICATION OF THE INVENTION
El campo de aplicacion de la presente invencion se enmarca dentro del sector de la odontologfa, centrandose particularmente en el ambito de la implantologfa dental, y mas concretamente, en las tecnicas de distraccion alveolar para la elongacion del hueso maxilar.The field of application of the present invention is framed within the dentistry sector, focusing particularly on the field of dental implantology, and more specifically, on alveolar distraction techniques for maxillary bone elongation.
ANTECEDENTES DE LA INVENCIONBACKGROUND OF THE INVENTION
La distraccion alveolar en implantologfa dental, es una tecnica quirurgica descrita con anterioridad mediante la cual se consigue la elongacion del hueso maxilar y de los tejidos que le rodean. Esta tecnica se realiza mediante un corte u osteotomfa que se realiza en el maxilar obteniendo dos partes, una fija y otra parte movil o fragmento de transporte. Estas dos partes quedan unidas mediante un dispositivo llamado “distractor” que se fija por unaAlveolar distraction in dental implantology, is a surgical technique described previously by which the elongation of the maxillary bone and surrounding tissues is achieved. This technique is performed by means of a cut or osteotomy that is performed in the jaw obtaining two parts, one fixed and another mobile part or transport fragment. These two parts are joined by a device called a "distractor" that is fixed by a

parte en la parte fija del hueso y por otra parte en la parte movil o fragmento oseo de transporte.part in the fixed part of the bone and on the other hand in the mobile part or bone transport fragment.
Mediante una activacion del dispositivo distractor, cada una de las citadas partes del mismo se desplazan una en direccion contraria de la otra, consiguiendo asf elongar el callo de fractura producido por la osteotomfa de separacion de las dos partes oseas y, por lo tanto, aumentar la dimension vertical del hueso y de los tejidos que le rodean.By activating the distracting device, each of the aforementioned parts of the displacement moves one in the opposite direction of the other, thereby elongating the fracture callus produced by the osteotomy of separation of the two bone parts and, therefore, increasing the vertical dimension of bone and surrounding tissues.
Para poder hacer este movimiento las dos partes del distractor necesitan tener un buen anclaje mecanico en el hueso, este anclaje mecanico se consigue mediante las espiras exteriores que tiene el dispositivo.To be able to make this movement the two parts of the distractor need to have a good mechanical anchor in the bone, this mechanical anchor is achieved by means of the outer turns that the device has.
Sin embargo, en determinadas ocasiones y dependiendo de la biologfa osea, el anclaje mecanico del casquillo o parte superior del distractor sobre el fragmento libre del hueso no es lo suficientemente robusto y pierde la estabilidad. La perdida de dicha estabilidad supone que estos dos elementos, casquillo superior y hueso superior, no se muevan de forma solidaria, sino que se muevan uno independientemente de del otro, impidiendo asf el proceso de distraccion de tejidos.However, on certain occasions and depending on the bone biology, the mechanical anchoring of the cap or upper part of the distractor on the free bone fragment is not robust enough and loses stability. The loss of said stability means that these two elements, upper bush and upper bone, do not move in solidarity, but move one independently of the other, thus preventing the process of distraction of tissues.
El objetivo de la presente invencion es, pues, el desarrollo de un dispositivo en forma de grapa cuya finalidad es la de mantener unidos dicha parte superior o casquillo del distractor al fragmento libre del hueso.The objective of the present invention is, therefore, the development of a staple-shaped device whose purpose is to keep said upper part or bushing of the distractor attached to the free bone fragment.
Por otra parte, y como referencia al estado actual de la tecnica, cabe senalar que, al menos por parte del solicitante, se desconoce la existencia de ningun otro dispositivo de fijacion o invencion similar que presente unas caracterfsticas tecnicas, estructurales y constitutivas semejantes a las que presenta el que aquf se preconiza, segun se reivindica.On the other hand, and as a reference to the current state of the art, it should be noted that, at least on the part of the applicant, the existence of any other fixing device or similar invention that presents technical, structural and constitutive characteristics similar to which is presented here, as claimed.
