Improved mandibular distractor

Improved mandibular distractor, comprised of five pieces. The first piece of adjustable anchorage has externally welded bilateral plates that are anatomical perforated symmetrical and easily removable, which adjusts to the jaw using anchoring screws. A second more external cylindrical piece with externally welded bilateral plates, like those of the first piece and with an internal hexagonal configuration that will fit with the second piece. A third intermediate piece of external hexagonal conformation that will fit inside the external piece allowing immobility, having an internal threaded configuration. A fourth piece (more internal) is a screw that will turn with the thread of the intermediate piece being extra-oral, together with the second and third piece forms the auto-guidable telescopic system transforming the turn into a linear displacement. A fifth piece is a protective hood.The improved mandibular distractor is used to slowly extend the jawbone.

Una segunda pieza más externa cilíndrica con placas bilaterales soldadas externamente, iguales a las de la primera pieza, y con una configuración interna hexagonal que encajará con la segunda pieza. Una tercera pieza intermedia de conformación hexagonal externa que encajará dentro de la pieza externa permitiendo aquí la inmovilidad, teniendo una configuración interna en rosca. Una cuarta pieza, (más interna) es un tornillo que girará con la rosca de la pieza intermedia siendo extraoral; junto con la segunda y tercera pieza forma el sistema telescópico autoguiable transformando el giro en un desplazamiento lineal. Una quinta pieza es un capuchón protector. El distractor mandibular perfeccionado se utiliza para alargar lentamente el hueso mandibular. Improved mandibular distractor, comprised of five pieces.
