Intra-radicular retention with custom designed CAD-CAM fibRe-reinforced composite post-core: a dental technique

Prim Dent J. 2024 Jun;13(2):53-57. doi: 10.1177/20501684241249546.

Abstract

A technique is outlined for utilising a polymeric composite reinforced with glass fibres in a three-dimensional mesh as a post-core in aesthetic cases. The clinical procedure involves obtaining an impression of the root canal space, scanning the definitive cast, and milling a fibre-reinforced composite post-core. Subsequently, the intra-radicular post-core is cemented using an adhesive resin cement. The use of custom-made computer-aided design-computer-aided manufacturing (CAD-CAM) fibre-reinforced composite post-core facilitates repairability, provides better adaptation to the root canal space, avoids uneven cement thickness, ensures chemical adhesion to resin cement, and promotes favourable aesthetics when combined with all-ceramic crowns.

Keywords: CAD-CAM; fibre-reinforced composite; post and core technique.
