Resumen
Las fibras son utilizadas en múltiples aplicaciones clínicas en odontología. Los
compuestos reforzados con fibra (FRC) son materiales a base de resina que contienen fibras
destinadas a mejorar sus propiedades físicas. El presente estudio tiene como objetivo evaluar
la resistencia a la fractura que aportan las distintas fibras en restauraciones directas y
determinar cuál utilizar en cada situación clínica. Se llevó a cabo una búsqueda específica en
la base de datos Medline/Pubmed, Epistemonikos y Google Académico utilizando los
siguientes términos: Fiber Reinforced Composite”, “Fiberglass Reinforcement” y
“Polyethylene Fiber”. Luego de aplicar nuestros criterios de inclusión se seleccionaron 4
estudios en la síntesis cualitativa. Los principales hallazgos reportan una diferencia en la
resistencia a la fractura en dientes tratados con fibras en comparación a la resina convencional
en todos los estudios in vitro evaluados, donde, el uso de fibras puede servir tanto en las
restauraciones de grandes cavidades provocadas por lesiones cariosas como para la reducción
del riesgo de fractura en el recambio de estas. Por tanto, el uso de fibras puede servir tanto
en las restauraciones de grandes cavidades provocadas por lesiones cariosas como para la
reducción del riesgo de fractura en el recambio de estas. No obstante, producto de las
limitaciones metodológicas de los estudios analizados no es posible generar
recomendaciones clínicas sobre la aplicabilidad de las fibras.
The fibers are used in multiple clinical applications in dentistry. Fiber Reinforced Composites (FRC) are resin-based materials that contain fibers intended to improve their physical properties. The objective of this study is to evaluate the resistance to fracture provided by the different fibers in direct restorations and to determine which one to use in each clinical situation. A specific search was carried out in the Medline/Pubmed, 2 Epistemonikos and Google Scholar databases using the following terms: Fiber Reinforced Composite”, “Fiberglass Reinforcement” and “Polyethylene Fiber”. After applying our inclusion criteria, 4 studies were selected in the qualitative synthesis. The main findings report a difference in fracture resistance in teeth treated with fibers compared to conventional resin in all the in vitro studies evaluated, where the use of fibers can serve both in restorations of large cavities caused by carious lesions and to reduce the risk of fracture in the replacement of these. Therefore, the use of fibers can serve both in restorations of large cavities caused by caries and for reducing the risk of fracture in their replacement. However, due to the methodological limitations of the studies analyzed, it is not possible to generate clinical recommendations on the applicability of the fibers.
