Fiber-Optimized Restoration: A Novel Approach to Strengthening Endodontic Posts With Dentapreg®

This case report discusses the management of a 42-year-old female patient with mature permanent teeth exhibiting open apices and significant structural damage due to trauma. Following incomplete endodontic treatment, teeth 21 and 22 presented with Ellis Class III fractures and open apices, while tooth 11 had a closed apex with an ill-defined radiolucency. Treatment involved apexification using Biodentine (Septodont, Saint-Maur-des-Fossés, France), laser-assisted disinfection, and reinforcement with fiber-reinforced composites (Dentapreg® Ultra Fine Mesh (UFM), Advanced Dental Material, Brno, Czech Republic). Post-endodontic restoration included porcelain-fused-to-metal crowns. The integration of modern materials and techniques, such as laser disinfection and fiber-reinforced posts, resulted in successful structural reinforcement and apical closure, highlighting the effectiveness of contemporary endodontic approaches in treating complex cases.
