Resumen
En la actualidad, se ha propuesto un material resinoso reforzado con fibras cortas como sustituto dentinario, el que tendría la capacidad de, a través de una restauración directa de bicapa, devolver e imitar la función del complejo amelo-dentinario. El objetivo de esta revisión actualizada fue presentar una descripción general de las propiedades físico-mecánicas y estéticas de los composites reforzados con fibras cortas en contraste con sus homólogos convencionales particulados y Bulkfill, y así brindar al clínico una comprensión detallada de este nuevo material según la evidencia científica disponible. Se realizó una búsqueda exhaustiva de la literatura hasta agosto del 2020. Se encuestó la gama de publicaciones relevantes utilizando PubMed y EBSCO. De los resultados de la búsqueda, sólo se consideraron los artículos que, con nuestro término de búsqueda que fue “Short fiber reinforced composite”, quedaron luego de aplicar nuestros criterios de inclusión. De los artículos evaluados seleccionados (N = 45), la mayoría eran investigaciones de laboratorio con varios diseños de muestras, estandarizados de acuerdo con la norma ISO o con preparaciones en dientes extraídos/artificiales; sólo cuatro artículos fueron informes clínicos In Vivo. Se observó en general un buen comportamiento físico-mecánico de las resinas reforzadas con fibras cortas en relación con sus pares convencionales y Bulkfill, en varios puntos siendo superior a los mismos. En los estudios revisados, la técnica de restauración biomimética en bicapa, donde se utilizó el composite reforzado con fibras cortas como núcleo, mostró características prometedoras y, por lo tanto, podría recomendarse como una opción de tratamiento en casos de pérdida dentaria extensa.
Nowadays, a resinous material reinforced with short fibers has been proposed as a dentin substitute, which would have the ability, through a direct bilayer restoration, to return and imitate the function of the amelo-dentinal complex. The objective of this updated review was to present a general description of the physico-mechanical and aesthetic properties of composites reinforced with short fibers in contrast to their conventional particulate and Bulkfill counterparts, and thus provide the clinician with a detailed understanding of this new material according to the scientific evidence available. A comprehensive literature search was conducted up to August 2020. The range of relevant publications was surveyed using PubMed and EBSCO. From the search results, only articles that, with our search term being “Short fiber reinforced composite”, remained after applying our inclusion criteria were considered. Of the selected evaluated articles (N = 45), the majority were laboratory investigations with various sample designs, made according to the ISO standard or with preparations on extracted/artificial teeth; only four articles were In Vivo clinical reports. In general, a good physical-mechanical behavior of the short fiber reinforced resins was observed in relation to their conventional and Bulkfill pairs, in several points being superior to them. In the reviewed studies, the biomimetic bilayer restoration technique, where the short fiber reinforced composite was used as the core, showed promising characteristics and could, therefore, be recommended as a treatment option in cases of extensive tooth loss.
