Digital, Conventional, And Biomimetic Approaches for Restoring Endodontically Treated Teeth

Endocrowns are preferred over the post-retained crown, especially at a young age for many reasons; they allow better gingival health and care due to placement of the supragingival margin, have greater fracture resistance limiting the risk for root fracture, thus improving the long-term prognosis of ETMs and has a superior ability to restore ETMs with short crowns, calcified root canals, and thin roots. Furthermore, using CAD/CAM technology facilitates Endocrowns preparation making it simpler with less invasive techniques that can be prepared, fabricated, and cemented in a single visit. The high demand for permanent, esthetic, and conservative restorations has directed clinicians to restore permanent ETMs at a young age with Endo crowns as final coronal restorations.

In addition, Biomimetic dentistry leverages modern materials to replicate the biological and mechanical functions of natural teeth, presenting a distinct approach that minimizes the need for extensive tooth reduction and post-placement, particularly advantageous for endodontically treated teeth. Utilizing fiber-reinforced composites, this technique aims to strengthen the dentin-resin bond and evenly distribute occlusal forces across the restoration. By closely adhering to the intact tooth's natural contours and functionality, biomimetic restorations not only preserve more of the natural tooth structure but also reduce stress and strain within the restored tooth. This approach enhances longevity and minimizes the risk of bond failure, with any necessary repairs being straightforward and contributing to the restoration's sustainability. This study explores the application of fiber-reinforced composites within a biomimetic framework for restoring endodontically treated teeth, aiming to achieve durable and biologically compatible outcomes.
