Introduction: The filling core associated with the fiberglass pins, appeared to meet the aesthetic demand and provide better distribution of chewing loads in the root, bone and periodontium, minimizing the rate of root fractures. Objective: Thus, the objective of this study was to present a clinical case report of rehabilitation of endodontically treated teeth, using a direct intra-radicular retainer, made with fiberglass pins (FGP), anatomically individualized with composite resin and, subsequently, metal-ceramic crown. The present clinical case describes the rehabilitation of the element 11 that presented a root canal with a diameter and shape not compatible with prefabricated FGP. Conclusion: Based on the 5-year follow-up after installation, it could be concluded that both the professionals involved and the patient considered the clinical outcome satisfactory. This used technique minimizes the resin cement layer that can cause FGP retention failures, having, therefore, similar adaptation characteristics to the conventional cast metal core technique. Moreover, as seen in the literature, intra-radicular retainers made by this technique, present a modulus of elasticity very close to the remaining dentin, thus being able to avoid fractures of the dental remaining over time.
