Resumen
Este estudio observacional, transversal de tipo serie de casos tiene como objetivo
describir la aplicación de técnicas restauradoras biomiméticas en dos dientes
endodónticamente tratados (DET) con compromiso estructural. Este estudio constó con dos
casos clínicos en los cuales se confeccionaron restauraciones extensas sobre dientes
endodónticamente tratados utilizando biomateriales como fibras de polietileno de alto peso
molecular y resinas reforzadas con fibras de vidrio mediante técnicas restauradoras
biomiméticas, donde cada caso fue abordado de una manera distinta, a través de
restauraciones directas e indirectas. El primer caso clínico fue tratado sin postes de fibra. El
enfoque convencional requeriría un poste de fibra o metal fundido y una corona de cobertura
total, pero en este caso se eligió un enfoque biomimético. Por lo tanto, se utilizó una biobase
para el reemplazo de la dentina y una restauración de cerámica reemplazó el esmalte. La
biobase se reforzó con fibra de polietileno en su base para reducir el estrés generado en la
capa híbrida. La reconstrucción del núcleo de dentina se llevó a cabo con una resina
compuesta reforzada con fibra de vidrio corta, que tiene propiedades mecánicas similares a
la dentina y para el reemplazo del esmalte se utilizó una cerámica de disilicato de litio. El
segundo y último caso clínico consistió en realizar una restauración directa OD sobre una
biobase, también en un DET.
The objective of this observational, cross-sectional, case series study is to describe the application of biomimetic restorative techniques in two endodontically treated teeth with structural compromise. This study consisted of two clinical cases in which extensive restorations were fabricated on endodontically treated teeth using biomaterials such as high molecular weight polyethylene fibers and glass fiber reinforced resins through biomimetic restorative techniques, where each case was approached in a different way, through direct and indirect restorations. The first clinical case was treated without fiber posts. The conventional approach would require a fiber post or cast metal and a full-coverage crown, but in this case a biomimetic approach was chosen. Therefore, a biobase was used for dentin replacement and a ceramic restoration replaced the enamel. The biobase was reinforced with polyethylene fiber at its base to reduce the stress generated in the hybrid layer. Reconstruction 2 of the dentin core was carried out with a short glass fiber reinforced composite resin, which has similar mechanical properties to dentin, and a lithium disilicate ceramic was used to replace the enamel. The second and last clinical case consisted of performing a direct OD restoration on a biobase, also in a DET.
