Traumatic dental injuries involving the anterior teeth frequently present as complicated crown fractures, posing challenges in achieving functional and esthetic rehabilitation. Conservative fragment reattachment techniques, reinforced with fiber posts or polyethylene fibers, provide an ultraconservative approach while preserving tooth structure. In this report, two male patients (25 and 42 years old) presented with complicated crown fractures of the maxillary anterior teeth following trauma. Both cases were managed with nonsurgical root canal therapy followed by conservative fragment reattachment. Fiber reinforcement was employed using prefabricated fiber posts in one case and Ribbond polyethylene fiber in the other. Clinical and radiographic evaluation demonstrated stable fragment reattachment, satisfactory esthetic results, and restored occlusal function. Both patients remained asymptomatic on follow-up. These findings suggest that conservative reattachment of fractured tooth fragments using adhesive techniques, combined with fiber reinforcement, is a predictable and effective treatment for complicated crown fractures, ensuring functional stability and optimal esthetic outcomes while preserving natural tooth structure.
