Resumen
Este trabajo tiene su importancia ya que es de vital importancia para el odontólogo lograr una adecuada interrelación entre la prótesis a instalar y el periodonto, de tal manera que siempre se mantenga la salud periodontal durante y después al tratamiento rehabilitador. Se requiere entre otras aspectos para preservar la salud periodontal, que la prótesis posea contornos anatómicos adecuados, textura superficial lisa (superficie bien pulida) y una exactitud de adaptación cervical dentro de los límites considerados clínicamente aceptables. Para lograr esto último es necesario conocer la importancia del sellado marginal así como aspectos sobre la línea de terminación.
Tiene como propósito dar a conocer que un diente que ha sufrido un tratamiento endodontico tiene algunas características que lo diferencian de los dientes vitales y que influyen sobre la restauración. La primera diferencia importante es que en el diente endodonciado, tenemos la posibilidad de utilizar el conducto radicular para ayudarnos en la restauración, ya sea para apoyar la retención o para mejorar la simbiosis entre la corona dentaria restaurada y la raíz.
Por otro lado, el diente desvitalizado pierde el efecto biológico que la pulpa ejerce sobre la dentina y que, al final, se traduce en una perdida de elasticidad que poco a poco va haciendo al diente mas sensible a la fractura. Una tercera característica del diente endodonciado es que, por lo general, presenta una importante destrucción de la corona dentaria, ya sea por el proceso que dio origen a la necesidad de realizar un tratamiento de conductos o simplemente por la tendencia actual a hacer aperturas camerales muy amplias para facilitar la instrumentación. La conservación de los rebordes marginales es muy importante para evitar las fracturas coronarias. Las cavidades mesiooclusodistales (MOD), que rompen los dos rebordes marginales, son las de mayor riesgo.
This work is of importance because it is vitally important for the dentist to achieve adequate interface between the prosthesis and periodontal installed , so that periodontal health is always maintained during and after the rehabilitation treatment . It requires, among other aspects to preserve periodontal health , the prosthesis has adequate anatomical contours , surface texture smooth ( well polished surface) and an accuracy of cervical adaptation within the limits considered clinically acceptable . To achieve the latter is necessary to know the importance of marginal sealing as well as aspects of the finishing line . Its purpose is to publicize that a tooth that has undergone endodontic treatment has some characteristics that differentiate it from vital teeth and influencing restoration. The first major difference is that the root canal treated tooth, we are able to use the canal to help in the restoration , either to support or to improve retention symbiosis between the restored tooth crown and root. Furthermore, devitalized tooth loses the biological effect exerted on the pulp and dentin , in the end , results in a loss of elasticity that is slowly making the most sensitive tooth fracture . A third characteristic of endodontic tooth is that usually presents a major destruction of the tooth crown , either by the process that gave rise to the need for a root canal or just for the current trend to make cameral openings very wide to facilitate the implementation . The conservation of the marginal ridges is very important to prevent coronary fractures. The mesiooclusodistales cavities ( MOD) , breaking the two marginal ridges , are the highest risk.
