The programme

The Flow Injection Technique has made restorative aesthetic dentistry more predictable and reproducible. But what determines the outcome is not the injection: it is the design that precedes it. This lecture shifts the centre of gravity from execution to design, and shows how a process of analysis and design governs every clinical phase that follows. The starting point is the face and its function. Through a facially-driven digital workflow — aesthetic analysis, previsualization shared with the patient and digital wax-up — the case is designed before it is executed. Previsualization is not just a technical tool: it is the lever that makes the patient part of the project and drives their motivation. From this design come the indices that turn aesthetics into a repeatable procedure. Through clinical cases — from the simplest situations to complex rehabilitations with an increase in vertical dimension — the lecture will present the phases of the Flow Injection Technique and the decision criteria that show when the injective approach is the right choice, and when it is not. In the background remains the reason that gives meaning to it all. A predictable, minimally invasive technique that can be learned and reproduced does not only enrich those who perform it: it multiplies the number of patients who can access a high-quality aesthetic and functional result. Mastering the injective approach means being able to give a smile back to those who believed it was no longer possible — and that is perhaps the most concrete reason why a modern dentist should know it. Design leads, technique executes.

Contemporary restorative dentistry has evolved toward increasingly conservative treatments, where the preservation of tooth structure and adhesion represent the fundamental pillars of clinical success. In this context, direct composite resins, combined with state-of-the-art adhesive protocols, enable the rehabilitation of the posterior region with highly aesthetic, functional, and predictable results. The Stamp Technique has established itself as an innovative alternative for the precise reproduction of occlusal anatomy, reducing modeling time, optimizing occlusal fit, and minimizing the need for adjustments and polishing. Its original application is particularly valuable in conservative cavity restorations, where the original anatomy can be preserved prior to preparation. Currently, we apply the same technique to cases of generalized wear, where rehabilitation involves modifying the vertical dimension of occlusion. This lecture will address the biological and adhesive principles underpinning minimally invasive oral rehabilitation with composite resins, case selection criteria, clinical planning, and a step-by-step protocol for applying the Stamp Technique in these cases. Additionally, the most suitable materials, the procedure's main advantages and limitations, common clinical errors, and strategies to avoid them will be discussed, supported by current scientific evidence and clinical follow-up cases. The objective is to provide dentists with practical, evidence-based tools to incorporate this technique into their daily practice, achieving direct restorations with high predictability, excellent aesthetic integration, and adequate clinical longevity.
