What is a “universal” adhesive?

New Definition of “Universal Adhesives”

• Hydrophobic enough to be used as a single-layer adhesive.
• Any etching technique: total-etch, self- etch, or selective-etch modes.
• Both direct and indirect clinical procedures using light-cure, dual-cure, or self-cure materials (without the need for a separate self-cure activator).
• Can bond to indirect substrates (low film thickness < 10 µm).
