ABSTRACT
The study aimed to ultraconservatively manage two cases of complicated crown fractures by reattaching the fractured fragments using individually formable E-glass fiber post. Traumatic dental injuries must be managed with a multidisciplinary approach to maximize healing while maintaining function and esthetics. Complicated crown fractures have an incidence of up to 20% of all traumatic dental injuries. The most common injuries are in the maxillary anterior region, which can have a physical and psychological impact on the patient. The present case series includes two similar cases of complicated crown fracture of the maxillary right central incisor with the segment partially attached to the palatal mucosa at the level of gingival margin. Following initial stabilization using canal projector technique, non-surgical endodontic treatment was carried out. The post spaces were prepared minimally to accommodate a soft and flexible, individually formable resin‑impregnated E‑glass fiber post (everStick Post™, GC Corporation, Tokyo, Japan). This customizable anatomic post was used to retain the fragment in both cases. Its modulus of elasticity is comparable to that of dentin, and thus facilitates even distribution of forces. Dental composites were used to mask the fracture lines from the labial aspect, and the restorations were finished and polished. Reattachment of the fragment, previously a provisional restoration, is now the permanent treatment of choice, made possible by advances in adhesive technology. The procedure of reattachment in this case series using individually formable glass fiber post, neither required removal of the fractured fragment nor drilling of the coronal fragment and therefore is an ideal, ultraconservative approach to preserve the fragment intraorally. Long-term follow-up is necessary to evaluate the stabilization of the fragment and the overall functional and esthetic outcome of this treatment protocol.
