Background: Direct composite restorations in posterior teeth are technique-sensitive and time-consuming. The injection molding technique, supported by digital workflow, provides a predictable and efficient alternative. Case Presentation: A 27-year-old patient presented with caries in mandibular first molar (#36). After intraoral scanning and virtual design in exocad, a 3D-printed model and transparent silicone index were fabricated. Following caries excavation, indirect pulp capping with MTA, and placement of a GIC base, the index was seated intraorally. Flowable composite was injected, light-cured, and polished, achieving accurate occlusal anatomy with minimal adjustments. Conclusion: The digitally guided injection molding technique with flowable composite (Wizdent Pidilite master design) offers a time-saving, predictable, and esthetic solution for posterior restorations, overcoming the limitations of conventional layering methods.
