Resumen
Los postes de fibra de vidrio han ganado popularidad por sus favorables propiedades biomecánicas, son más flexibles y distribuyen mejor las fuerzas que soportan las piezas dentarias, aunque en algunos casos resultan en fracturas tanto radiculares cómo del mismo poste, provocadas por una mala instrumentación, cementación excesiva o fuerzas parafuncionales. La importancia de conocer como remover un poste de fibra de vidrio es vital al realizar un retratamiento de endodoncia, también para cambiarlo debido a la fractura del poste, cómo también por el fracaso de la restauración.
Actualmente se utiliza un sistema de restauración, en piezas dentarias con tratamiento de conducto previo y que cuyas coronas fueron afectadas en gran proporción por caries o accidentes, utilizando postes de fibra de vidrio, los cuales brindan excelentes resultados por su tratamiento en una sola sesión, gran capacidad de adhesión, adaptación y retencion. Sin embargo nos presta profunda atención cuando presenta un problema y mucho más que tipo tratamiento que debemos utilizar en caso de que haya necesidad de removerlos por una razón secundaria.
Para la presente investigación realizamos bibliográficamente aportes científicos que evalúan las técnicas de remoción de postes más utilizadas por los clínicos, haciendo énfasis que todas son de estudios in vitro, encontrando que existen técnicas mecánicas, técnicas de ultrasonido, técnicas rotasónica y técnicas combinadas,
El objetivo de la presente investigación es: determinar las técnicas de remoción de postes de fibra de vidrio fracturado en el interior del conducto radicular para evitar la extracción de la pieza dentaría.
Poles fiberglass have gained popularity because of their favorable biomechanical properties , are more flexible and better they distribute forces that support the teeth , although in some cases result in both root fractures how the same post , caused by poor instrumentation , cementing excessive or parafunctional forces. The importance of knowing how to remove a pole fiberglass is vital to perform retreatment , also to change due to fracture of the post, how also the failure of the restoration. Currently a system restore is used on teeth with treatment prior duct and whose crowns were affected to a great extent by decay or accident , using poles fiberglass , which provide excellent results for your treatment in one session , great adhesion ability , adaptation and retention . However we pay close attention when presenting a problem and more than kind treatment we use in case there is need to remove a secondary reason . To perform this investigation Bibliographically scientific contributions that assess removal techniques most commonly used by clinical posts , emphasizing that they are all in vitro studies , finding that there are mechanical techniques , ultrasound techniques , rotasónica techniques and combined techniques , The objective of this research is to determine the removal techniques fiberglass poles fractured inside the root canal to prevent removal of the tooth.
