Biomimetic Semi-Direct Restorations and Secure Bonding with Fibers in Endodontically Treated Premolars: A Case Report

Abstract

The rehabilitation of endodontically treated teeth is a common clinical challenge that demands a technique capable of preserving the remaining tooth structure while respecting adhesive principles. This report presents the clinical rehabilitation of two maxillary premolars with extensive coronal loss, both previously endodontically treated, one of which had a pre-existing glass-fiber post. Treatment involved maintaining this post and fabricating semi-direct composite resin restorations for both teeth, following the principles of biomimetic dentistry. The case illustrates the clinical applicability of conservative, adhesion-based approaches. The use of semi-direct composite restorations, combined with fiber reinforcement, proved to be a viable and effective alternative for posterior teeth with major structural compromise. We conclude that individualized planning, coupled with strong technical-scientific proficiency, is essential for clinical success in cases of severe coronal rehabilitation.
