Restoring endodontically treated teeth (ETT) that exhibit cracks, enlarged roots, or weakened root walls is a frequent challenge in dental practice. The present study describes three cases in which contemporary restorative techniques were employed and suggests that applying Ribbond tape (RT) to ETT can improve fracture resistance and better prevent the propagation of cracks compared with traditional methods. Although extensive research has been conducted on fiber-reinforced composites, studies evaluating the clinical use and durability of fiber-reinforced composites to restore ETT are limited. This report strictly adhered to the case report (CARE) guidelines, and the treatments were initiated only after signed informed consents were obtained from the patients. Therefore, the old restorations were removed from the teeth that required intervention and composite resin core build-up was created, followed by endodontic treatments or retreatment. Subsequently, the endodontic accesses were reinforced with RT. The protective restorations were performed and bonded. The two-year follow-ups showed that the patients had complete remission of signs and symptoms, and they remain under monitoring. The study emphasizes the importance of internal reinforcement of ETT and strengthening weakened walls with a resin core build-up reinforced with fibers like RT. This approach enhances mechanical retention, inhibit fracture propagation, and establish a strong chemical bond between RT and resin. It is suggested to be a promising strategy for increasing the longevity and strength of the teeth, providing a conservative and effective alternative to traditional methods.
修复出现裂缝、牙根增大或根壁薄弱的经牙髓治疗的牙齿（ETT）是牙科实践中经常面临的挑战。本研究描述了三例采用当代修复技术的病例，并表明与传统方法相比，将Ribbond胶带（RT）应用于ETT可提高抗折性并更好地防止裂缝扩展。尽管对纤维增强复合材料进行了广泛研究，但评估纤维增强复合材料修复ETT的临床应用和耐久性的研究有限。本报告严格遵循病例报告（CARE）指南，仅在获得患者签署的知情同意书后才开始治疗。因此，从需要干预的牙齿上去除旧的修复体，制作复合树脂核，随后进行牙髓治疗或再治疗。随后，用RT加强牙髓腔。进行保护性修复并粘结。两年的随访表明，患者的体征和症状完全缓解，他们仍在接受监测。该研究强调了对ETT进行内部增强以及用如RT等纤维增强的树脂核来加固薄弱牙壁的重要性。这种方法增强了机械固位，抑制了骨折扩展，并在RT和树脂之间建立了牢固的化学键。它被认为是一种增加牙齿寿命和强度的有前景的策略，为传统方法提供了一种保守且有效的替代方案。
