System for temporary gingival retraction offering a wide range of indications, including conventional and digital print, sealing/bonding, Class II and V preservative care, and implantology. Viscosity has been carefully calculated to open the sulcus effectively without damaging the epithelial attachment. The opening quality is equivalent to that obtained with a retraction cord. Without injury, bleeding or pain, the procedure is both safe and effective, with no need to wait for the tissue to heal since it has not been damaged.
