Según el ejemplo de ejecución representado, el equipo de herramientas para la extracción de restos de instrumentos fracturados en el interior de los conductos radiculares, que se preconiza, está constituido por una especial punta ultrasónica diamantada (1) prevista para realizar un acceso radicular hasta la lima fracturada para el resto de herramientas siguientes mediante un ensanchamiento de la anchura del conducto (2) practicado en la pieza dental (3) que se trate, hasta la zona donde se encuentra de lima fracturada, a fin de facilitar la introducción del segundo instrumento, formado por una punta ultrasónica fina (4), que libera de dentina la parte coronal del resto de lima a extraer para que pueda ser enganchada por la tercera pieza formada por un tubo metálico que en su extremo lleva una pieza extractora (5): cavidad cónica hembra complementaria a la sección transversal de la lima fracturada, y con un borde cortante (6) afilado que trabaja en el sentido contrario al de giro de trabajo de la lima fracturada, con lo que mediante giro, en este sentido contrario, se produce el encaje y desenganche de la lima a extraer de las paredes de dentina que le rodean, desencajándola de estas paredes y procediendo a su extracción de una manera predecible, eficaz y sin extracción excesiva de dentina que debilitaría las remanentes paredes radiculares del diente.According to the example of execution represented, the tool kit for extracting instrument debris fractured inside the root canals, which advocates, is constituted by a special ultrasonic tip diamond (1) intended to make a root access to the fractured file for the rest of the following tools by a widening of the width of the duct (2) practiced in the dental piece (3) in question, up to the area where it is located fractured file, in order to facilitate the introduction of the second instrument, formed by a fine ultrasonic tip (4), which releases of dentin the coronal part of the rest of lime to extract so that can be hooked by the third piece formed by a tube metallic that at its end carries an extractor (5): cavity conical female complementary to the cross section of the file fractured, and with a sharp cutting edge (6) that works in the counter-clockwise direction of the fractured file, with what by turning, in this opposite direction, the fit and release of the file to be extracted from the dentin walls around him, dislodging them from these walls and proceeding to his extraction in a predictable, efficient and non-extraction manner excessive dentin that would weaken the remaining walls tooth roots.

Mediante estos medios, su utilización, es elemental, puesto que en una primera fase, mediante la punta ultrasónica diamantada (1) de acceso radicular se procede a ensanchar la anchura del conducto (2) de la pieza dental que se trate, y en la que ha quedado un resto de la lima fracturada empleada, ensanchamiento que tiene como fin, facilitar, la introducción de la punta ultrasónica (4) de acceso coronal que libera de dentina la parte coronal del resto a extraer para que pueda ser prendido por la oquedad de la punta (5) del extractor, que girando en sentido contrario al que giró la lima fracturada, procede a enganchar el resto a extraer. Su oquedad hembra a la lima, borde cortante (6) y su sección ligeramente superior al de lima fracturada quitan cualquier resto de dentina de la parte coronal de la lima que no hubiera sido extraído previamente por la punta ultrasónica fina.Through these means, its use is elementary, since in a first phase, through the tip ultrasonic diamond (1) root access proceeds to widen the width of the duct (2) of the tooth that is try, and in which there is a remainder of the fractured file used, widening that aims to facilitate the introduction of the ultrasonic tip (4) of coronal access that releases the coronal part of the rest to be extracted from dentin so that can be turned on by the hollow of the tip (5) of the extractor, that turning in the opposite direction to which the fractured file turned, proceed to hook the rest to extract. His female cavity at file, cutting edge (6) and its section slightly higher than that of fractured file removes any dentin residue from the part coronal of the lime that had not been previously extracted by the fine ultrasonic tip.

Es preciso en la utilización de este equipo de herramientas, el máximo cuidado de no llegar a tocar con las primeras el resto de instrumento a extraer para que éste no pueda profundizar mas en el interior del conducto, así como en el empleo de la herramienta extractor (5) elegir el diámetro adecuado, siempre ligeramente superior al del fragmento a extraer, para que su sujeción sea segura mediante sus bordes cortantes (6).It is necessary in the use of this equipment tools, the utmost care not to touch the first the rest of the instrument to be extracted so that it cannot dig deeper inside the duct, as well as in the use of the extractor tool (5) choose the appropriate diameter, always slightly higher than the fragment to be extracted, so that its support is secure by means of its sharp edges (6).

La forma, materiales y dimensiones, podrán ser variables, y en general, cuanto sea accesorio y secundario, siempre que no altere, cambie o modifique la esencialidad de las herramientas que se han descrito.The shape, materials and dimensions may be variables, and in general, whatever accessory and secondary, always that does not alter, change or modify the essentiality of the tools that have been described.
