The injection moulding technique (IMT) offers a non-invasive method for dental restoration by using flowable composite materials within a transparent silicone index, which serves as a mould. This technique capitalizes on the fluid properties of the composite to seamlessly integrate with the natural tooth structure, often avoiding the need for tooth alteration and preserving tooth integrity. The etch-and-rinse process ensures that the procedure is both consistent and reproducible. This minimally invasive technique is particularly useful following orthodontic procedures, where slight changes in tooth shape or alignment are often necessary to achieve optimal aesthetic and functional results. The integration of orthodontic and restorative treatments is essential for optimal patient outcomes, especially in complex cases requiring multiple disciplines. This retrospective study examines the use of IMT for restoring maxillary lateral incisors in two pediatric patients (ages 12.6 and 12.3). The technique provides a temporary restoration until the patient is ready for permanent ceramic veneers, offering a conservative solution for orthodontic treatment completion. The IMT technique works best for addressing minor gaps or slight tooth misalignments. The cases presented show that the method is effective for treating irregular tooth sizes or shapes, especially when an additive approach is necessary without the need for invasive preparation. The IMT is a helpful tool for pediatric patients at various stages of orthodontic treatment. It aids in correcting discrepancies such as Bolton index variations and enhances tooth morphology. The addition of a digital workflow enables thermo-formed retainers to be created and delivered in the same visit as the IMT, resulting in cost and time efficiency. This technique simplifies the overall treatment process, improving clinical efficiency and outcomes in interdisciplinary orthodontic-restorative care.
