Composite resins are nowadays largely used in posterior restorations. This systematic use may generate a change of habits and requires a rigorous organization. In adhesive dentistry, clearing the visual field and controlling fluids as well as humidity are absolute requirements. Beyond the introduction, it will also be necessary, after deciding which technique (direct or indirect) must be used, to take into account the cavity “C factor” in the placement of the material and use a specific and efficient material, particularly the sectional matrices in order to perform an adequate reconstruction of the contact point. Complying with these simple rules allows to get a predictable and reproducible result as well as to satisfy our patients’ wishes.
