Pilar de implante dental.Dental implant abutment.

Objeto de la invencionObject of the invention

La presente invencion esta dirigida a un pilar para implantes dentales que permite su adaptation a varios angulos de trabajo de manera gradual.The present invention is directed to a dental implant abutment that allows its adaptation to various angles of work gradually.

La presente invencion permite su implementation en casos en los que se trate de un implante que se inserta en angulo recto como en varios angulos distintos dentro unos ciertos rangos respecto a un determinado plano definido entre dos puntos de articulation que permite el movimiento relativo entre las partes del implante.The present invention allows its implementation in cases in which it is an implant that is inserted at right angles as in several different angles within certain ranges with respect to a certain defined plane between two points of articulation that allows relative movement between the parts of the implant

Antecedentes de la invencionBackground of the invention

A dla de hoy son conocidas las soluciones que se aportan al problema tecnico de la insertion de piezas dentales en zonas que requieren de una fijacion de la pieza en la estructura osea de un implante o similar que permita a la pieza ser fijada a la misma del mismo modo que actua un la ralz de un diente natural.Today, the solutions that contribute to the technical problem of the insertion of dental pieces in areas that require a fixation of the piece in the bone structure of an implant or similar that allows the piece to be fixed to it are known The same way a root of a natural tooth acts.

Habitualmente los implantes tienen forma roscada y se fabrican con materiales biocompatibles que no producen reaccion de rechazo y permiten su union al hueso.Usually the implants have a threaded shape and are manufactured with biocompatible materials that do not produce a rejection reaction and allow their union to the bone.

La superficie del implante puede presentar diferentes texturas y recubrimientos, utilizadas habitualmente para aumentar su adhesion al hueso (osteointegracion si es de titanio y biointegracion si se trata de un material ceramico).The implant surface may have different textures and coatings, usually used to increase its adhesion to the bone (osseointegration if it is titanium and biointegration if it is a ceramic material).

Al reponer los dientes perdidos por medio de implantes se conserva mayor cantidad de hueso alveolar ya que este se reabsorbe al no recibir ningun tipo de estlmulo.When replacing lost teeth through implants, a greater amount of alveolar bone is conserved since it is reabsorbed by not receiving any type of stimulus.

La investigation cllnica ha llevado a un nuevo tipo de implante denominado transcigomatico, que permite un aprovechamiento maximo del hueso. Se trata de implantes en la zona del pomulo (hueso cigomatico), cuyo volumen no se ve afectado por la perdida dental, como sucede habitualmente con los huesos maxilares que pueden atrofiarse. Esta tecnica permite tratar a pacientes con poco hueso en la zona sin utilizar practicas mas agresivas y de peor pronostico como los injertos oseos.The clinical investigation has led to a new type of implant called transzygous, which allows maximum bone utilization. These are implants in the area of the cheekbone (zygomatic bone), whose volume is not affected by tooth loss, as usually happens with the maxillary bones that can atrophy. This technique allows patients with little bone to be treated in the area without using more aggressive and worse prognostic practices such as bone grafts.

Los implantes constan de un cuerpo que es la portion del implante dental que se disena para ser introducido en el hueso con el fin de anclar los componentes protesicos, generalmente con aspecto de tornillo aunque tambien existan otros tipos.The implants consist of a body that is the portion of the dental implant that is designed to be introduced into the bone in order to anchor the prosthetic components, usually with a screw-like appearance although other types also exist.

A su vez, este cuerpo se compone de 3 partes, que son: Modulo de cresta que es la porcion superior, el cuerpo que es la porcion intermedia y el apice que es la punta o extremo final.In turn, this body is composed of 3 parts, which are: Crest module that is the upper portion, the body that is the intermediate portion and the apex that is the end or end point.

Despues de insertar durante la primera etapa quirurgica el cuerpo del implante en el hueso, se coloca una cobertura sobre el modulo de cresta, con el fin de evitar el crecimiento de tejidos en el interior de la rosca que posee dicho modulo o porcion superior. Tras haberse producido la osteointegracion se realiza una segunda etapa quirurgica, en la que se desenrosca y retira el tornillo de cobertura y se enrosca el pilar deAfter inserting the implant body into the bone during the first surgical stage, a covering is placed on the crest module, in order to avoid the growth of tissues inside the thread that has said module or upper portion. After osseointegration has occurred, a second surgical stage is performed, in which the cover screw is unscrewed and removed and the abutment screw is screwed on.

cicatrizacion, cuya funcion es prolongar el cuerpo del implante sobre los tejidos blandos, y permitir la union de la mucosa gingival al modulo de la cresta, dando asi lugar al sellado gingival.scarring, whose function is to prolong the body of the implant over soft tissues, and allow the gingival mucosa to join the crest module, thus giving rise to the gingival seal.

El pilar es la porcion del implante que sostiene la protesis. Segun el metodo por el que se sujete la protesis al implante, distinguimos tres tipos de pilares:The pillar is the portion of the implant that supports the prosthesis. According to the method by which the prosthesis is attached to the implant, we distinguish three types of pillars:

• Pilar para atornillado el cual emplea un tornillo o rosca para fijar la protesis.• Pillar for screwing which uses a screw or thread to fix the prosthesis.

• Pilar para cementado en el que la protesis se une al pilar mediante cementos dentales, comportandose como un munon al que va unido una corona, un puente, o una sobredentadura.• Cemented abutment in which the prosthesis is attached to the abutment by means of dental cements, behaving like a munon to which a crown, a bridge, or an overdenture is attached.

• Pilar para retenedor el cual consta de un sistema de anclaje que soportara una protesis removible, que el paciente podra colocar y retirar manualmente.• Pillar for retainer which consists of an anchoring system that supports a removable prosthesis, which the patient can place and remove manually.

Por otra parte es conocido el uso de tornillos de fijacion para protesis en implantologia dental, cuyo acceso se realiza a traves de chimeneas que atraviesan las protesis dentales.On the other hand, it is known to use fixing screws for prostheses in dental implantology, whose access is made through chimneys that pass through dental prostheses.

Generalmente estos tornillos una cabeza con un hueco de seccion hexagonal y para su apriete se unas una llave de la misma forma que se inserta en el mismo eje del tornillo y del implante, limitando los casos de conexion directa y siendo necesario mas piezas intermedias y mas trabajo. Asimismo, para su uso es imprescindible cogerlos primero con los dedos para introducir la correspondiente llave de apriete y posteriormente introducirlos, vigilando que no se caigan, dentro de la protesis colocada en la boca.Generally, these screws have a head with a hexagonal section hole and for their tightening a wrench is attached in the same way that it is inserted in the same axis of the screw and the implant, limiting the cases of direct connection and being necessary more intermediate parts and more job. Likewise, for their use it is essential to take them first with the fingers to introduce the corresponding tightening wrench and then introduce them, ensuring that they do not fall, within the prosthesis placed in the mouth.

Para la colocacion de una protesis sobre un implante dental se necesita de un tornillo que va roscado al implante y que aguanta la protesis, el cual se coloca a traves de un agujero que lleva la protesis llamada chimenea y por no comprometer la estetica de la protesis, dicho agujero o chimenea tiene que quedar escondido por la parte bucal de la protesis, es decir, por la parte que no se ve a simple vista. La inclination de esta chimenea, que viene determinada por la position en que haya quedado el implante, no siempre tiene la mejor angulation debido a diversas causas (hueso deficiente, mala planificacion, y otras).For the placement of a prosthesis on a dental implant a screw is needed that is threaded to the implant and that supports the prosthesis, which is placed through a hole that carries the prosthesis called chimney and for not compromising the aesthetics of the prosthesis , said hole or chimney must be hidden by the oral part of the prosthesis, that is, by the part that is not visible to the naked eye. The inclination of this chimney, which is determined by the position of the implant, does not always have the best angulation due to various causes (poor bone, poor planning, and others).

Si existe una buena angulacion se puede realizar protesis de conexion directa, es decir, sin elementos intermedios; el tornillo se enrosca a traves de la chimenea de la protesis y se tapa dicha chimenea con precaution para poder acceder al tornillo en un futuro. La conexion directa facilita la labor del odontologo y del protesico, al no tener que hacer pasos intermedios abarata costes y facilita la extraction de la protesis para revisiones.If there is good angulation, direct connection prostheses can be performed, that is, without intermediate elements; The screw is screwed through the chimney of the prosthesis and the chimney is covered with precaution to access the screw in the future. The direct connection facilitates the work of the dentist and the prosthetic, not having to make intermediate steps lowers costs and facilitates the extraction of the prosthesis for revisions.

Si no existe buena angulacion, se puede emplear un pilar dinamico (Max. 20°) o se pueden colocar piezas intermedias anguladas y encima una protesis cementada que compromete la estetica (mas grosor) y dificulta la extraccion para revisiones (se pueden romper al extraerlas con el martillo dental), ademas de encarecer notablemente el trabajo. De todas estas soluciones el experto se encuentra con que dependiendo de a ubicacion y de la colocacion de la pieza a insertar se necesitan distintos tipos de implante y de angulos asi como una estructura resistente pero ligera que permita su colocacion de manera facil y eficaz.If there is no good angulation, a dynamic pillar can be used (Max. 20 °) or angled intermediate pieces can be placed and a cemented prosthesis on top that compromises the aesthetic (thicker) and makes it difficult to extract for revisions (they can be broken when extracted with the dental hammer), in addition to making work more expensive. Of all these solutions, the expert finds that depending on the location and the placement of the piece to be inserted, different types of implants and angles are needed, as well as a sturdy but lightweight structure that allows easy and efficient placement.

Descripcion de la invencionDescription of the invention

La presente invencion ofrece una solucion a los pilares existentes que no pueden trabajar en angulo de manera eficaz, para ello se presenta en el presente documento un pilar consistente en una base y una chimenea acoplada a la misma de manera pivotante respecto a dos puntos coplanarios, teniendo como resultado un movimiento de la chimenea con respecto de la base restringido mediante unos pliegues ubicados en una parte inferior y su cara exterior y con un recorrido limitado por la geometrla complementaria entre el interior de la parte inferior de la chimenea y el exterior de la parte superior de la base.The present invention offers a solution to existing pillars that cannot work at an angle effectively, for this purpose a pillar consisting of a base and a chimney pivotally coupled thereto with respect to two coplanar points is presented herein, resulting in a movement of the chimney with respect to the restricted base by means of folds located in a lower part and its outer face and with a limited path through the complementary geometry between the interior of the lower part of the chimney and the exterior of the upper part of the base.

En una posible realization de la invencion se presenta un pilar que comprende una base monolltica a la cual se encuentra acoplada de manera pivotante la chimenea. La base consta de un rebaje semicircular en todo el contorno interno superior y dos depresiones ubicadas opuestos y alineados entre si en parte superior de la base que hace de cuna y apoyo de la chimenea. El pilar tiene su chimenea y su base dispuestos de tal manera se acoplan entre si de manera pivotante respecto a dos puntos de union articulada entre la chimenea y la base, el movimiento relativo entre ambas piezas viene dado por los puntos de acople y por unos pliegues definidos entre dichos puntos que actuan de tal forma el movimiento se lleva a cabo mediante pasos y no de forma continuada.In a possible embodiment of the invention there is a pillar comprising a monolithic base to which the chimney is pivotally coupled. The base consists of a semicircular recess in the entire upper internal contour and two depressions located opposite and aligned with each other in the upper part of the base that acts as a cradle and fireplace support. The pillar has its chimney and its base arranged in such a way that they pivotally engage with respect to two points of articulation articulated between the chimney and the base, the relative movement between both pieces is given by the coupling points and by some folds defined between said points that act in such a way the movement is carried out in steps and not continuously.

En una posible realizacion alternativa, la base esta formada por dos piezas que se fijan entre si; esta posible realizacion alternativa se hace de especial utilidad en aplicaciones especificas en las que se hace necesaria alguna intervention que requiere un acceso especlfico al tornillo de anclaje del pilar a la estructura osea donde se va a llevar a cabo el implante.In a possible alternative embodiment, the base is formed by two pieces that are fixed together; This possible alternative embodiment is especially useful in specific applications in which some intervention is required that requires specific access to the pillar anchor screw to the bone structure where the implant is to be carried out.

En cualquiera de las posibles realizaciones, el principio que rige el movimiento relativo entre chimenea y base es el mismo, el pilar presenta al menos dos puntos de contacto total entre rebaje interno semicircular en todo el perlmetro y unas protuberancias que actuan como articulaciones pivotantes, estando el movimiento controlado mediante pasos definidos por unos pliegues ubicados en la parte inferior de la pared exterior de la chimenea, que contactan con la pared interior de la parte superior de la base; generando friction entre las crestas del pliegue y un resalte definido por un cambio de diametro del hueco del interior de la base. El movimiento se ve limitado por el extremo inferior de la chimenea que presenta una section decreciente de tal manera que el angulo maximo entre el eje longitudinal de la chimenea y aquel de la base es de aproximadamente 35°. Esto implica que la seccion final de la pared de la chimenea es decreciente en aproximadamente 35° con respecto del plano definido por su interior.In any of the possible embodiments, the principle that governs the relative movement between chimney and base is the same, the pillar has at least two points of total contact between semicircular internal recess throughout the perimeter and protrusions that act as pivoting joints, being the movement controlled by steps defined by folds located in the lower part of the outer wall of the chimney, which contact the inner wall of the upper part of the base; generating friction between the fold ridges and a protrusion defined by a change in the diameter of the hole inside the base. The movement is limited by the lower end of the chimney which has a decreasing section such that the maximum angle between the longitudinal axis of the chimney and that of the base is approximately 35 °. This implies that the final section of the chimney wall is decreasing by approximately 35 ° with respect to the plane defined by its interior.

Realizacion preferente de la invencionPreferred Embodiment of the Invention

En una realizacion preferente del objeto de la invencion aqul descrita se detalla un implante dental que tiene un pilar (1) de implante dental que permite su colocation de tal manera que se puede trabajar en angulo de manera que dicho angulo pueda ser facilmente fijado y desplazado sin que se produzcan grandes desplazamientos y pueda llevarse a cabo el movimiento de manera controlada.In a preferred embodiment of the object of the invention described herein, a dental implant is detailed which has a dental implant abutment (1) that allows its placement so that it can be worked at an angle so that said angle can be easily fixed and displaced. without large displacements and the movement can be carried out in a controlled manner.

Para ello se procede a una ubicar sobre la zona de trabajo una base (3) del pilar (1) la cual esta formada por un solido de revolution hueco en cuya pared interior se encuentran ubicado un rebaje (33) en todo contorno interno de forma semiesferica ubicado en la parte superior de la base (3) y con dos depresiones (34) en la parte superior de la misma, opuestas entre si. Sobre dicha base (3) se coloca una chimenea (2) formada por un solido de revolucion hueco que comprende en una parte inferior de su pared exterior unos pliegues (22) radiales comprenden una serie de crestas entre las cuales se definen unos valles formados sobre la pared exterior de la chimenea (2) y que parten de respectivas protuberancias (21) de forma semiesferica ubicadas sobre dicha pared exterior de la chimenea en una zona inferior de la misma y dispuestas de tal manera que se encuentran diametralmente opuestas y alineadas entre si. La fijacion entre la base (3) y la chimenea (2) se lleva a cabo de manera pivotante ya que dichas protuberancias (2l) se encuentran adaptadas para ser encajadas en el rebaje (33) de la base (3) fijando de manera pivotante la chimenea (2) a la base (3). De esta manera el movimiento relativo entre chimenea (2) y base (3) viene dado por la capacidad de los pliegues (22) de contraerse o expandirse.To do this, a base (3) of the pillar (1) is located on the work area, which is formed by a hollow revolution solid in whose interior wall a recess (33) is located in all internal contour so hemispherical located at the top of the base (3) and with two depressions (34) at the top of it, opposite each other. On said base (3) a chimney (2) formed by a hollow revolution solid is placed that comprises radial folds (22) in a lower part of its outer wall comprising a series of ridges between which valleys formed on the outer wall of the chimney (2) and which start from respective protuberances (21) semi-spherically located on said outer wall of the chimney in a lower area thereof and arranged in such a way that they are diametrically opposite and aligned with each other . The fixing between the base (3) and the chimney (2) is carried out in a pivotal manner since said protuberances (2l) are adapted to be fitted in the recess (33) of the base (3) pivotally fixing the chimney (2) to the base (3). In this way the relative movement between chimney (2) and base (3) is given by the ability of the folds (22) to contract or expand.

Dado que el movimiento pivotante se realiza en torno a las protuberancias (21) es la forma de los pliegues (22) y su disposition con respecto a las protuberancias (21) los queSince the pivoting movement is carried out around the protuberances (21) it is the shape of the folds (22) and their disposition with respect to the protuberances (21) which

permiten el movimiento pivotante, movimiento que se lleva a cabo paso a paso, siendo cada paso un movimiento correspondiente a la contraction o expansion de al menos uno de los pliegues (22). Para que dicho movimiento se pueda producir de manera correcta, y tal y como se aprecia en las figuras 4 y 5, la chimenea (2) tiene una section de pared 5 decreciente a partir de un punto correspondiente a un punto de inicio de la ubicacion de la protuberancia (21) hasta un extremo inferior de la chimenea (2), dicho seccion decreciente se lleva a cabo en un angulo tal que al producirse el movimiento de la chimenea (2) con respecto de la base, una cara interior ubicada en la parte inferior de la pared interior de la chimenea queda dispuesta en paralelo con una pared exterior de un 10 tornillo usado para fijar la base (3) en el lugar donde se coloca el implante. Asimismo la chimenea (2) presenta una seccion de pared decreciente en un extremo superior de la misma para facilitar el acceso al interior de la misma.they allow the pivoting movement, a movement that is carried out step by step, each step being a movement corresponding to the contraction or expansion of at least one of the folds (22). So that said movement can occur correctly, and as can be seen in Figures 4 and 5, the chimney (2) has a decreasing wall section 5 from a point corresponding to a starting point of the location from the protuberance (21) to a lower end of the chimney (2), said decreasing section is carried out at an angle such that when the movement of the chimney (2) with respect to the base occurs, an inner face located at The lower part of the inner wall of the chimney is arranged in parallel with an outer wall of a screw used to fix the base (3) in the place where the implant is placed. Likewise, the chimney (2) has a decreasing wall section at an upper end thereof to facilitate access to the interior thereof.

En una realization preferente del pilar (1) de la invention mostrada en las figuras 2a, 2b y 15 4 se tiene que la base (3) es monolltica y formada por un solo elemento, pero en unaIn a preferred embodiment of the pillar (1) of the invention shown in Figures 2a, 2b and 15 4, the base (3) has to be monolithic and formed by a single element, but in a

posible realizacion alternativa del objeto de la invencion mostrada en las figuras 1a-1c, 3a-3d y 5 el pilar (1) puede tener una base (3) en dos piezas. estando formada por una plataforma (32) definida por un solido de revolution hueco y una pieza de conexion (31) definida por un solido de revolucion hueco en cuya pared interior se encuentra el rebaje 20 (33); estando la pieza de conexion (31) fijada sobre la plataforma (32) formando asl lapossible alternative embodiment of the object of the invention shown in figures 1a-1c, 3a-3d and 5 the pillar (1) can have a base (3) in two pieces. being formed by a platform (32) defined by a hollow revolution solid and a connection piece (31) defined by a hollow revolution solid whose inner wall is the recess 20 (33); the connection piece (31) being fixed on the platform (32) thus forming the
