3M ESPE Adper Single Bond 2

3M™ ESPE™ Adper™ Single Bond 2 Adhesive is a highly advanced dental bonding agent designed for a wide range of dental applications. This adhesive builds upon the success of the original Adper Single Bond adhesive, offering a total etch, visible-light activated formula enriched with a 10% weight of 5nm diameter silica filler. It is primarily intended for direct light-cured restorative procedures and addressing cervical sensitivity. Moreover, it can be effectively employed in bonding laboratory-made composite or porcelain veneers when combined with RelyX™ Veneer Cement and for securing amalgam and other indirect dental applications in conjunction with RelyX™ ARC adhesive resin cement.

Adper Single Bond 2 Adhesive comes in two convenient options, either as a vial with a unique translucent design for visual inspection or in a hygienic unit dose delivery system, simplifying the application process. Its composition comprises key components like BisGMA, HEMA, dimethacrylates, ethanol, water, and a specialized photoinitiator system, along with a polyalkenoic acid copolymer known for its moisture resistance properties. The inclusion of nanotechnology is a notable feature, with 5 nanometer-diameter silica particles ensuring stable suspension without the need for frequent shaking, distinguishing it from adhesives with larger filler particles prone to settling.

This adhesive achieves its strong bond through a micromechanical process, involving the demineralization of enamel and dentin surfaces with a phosphoric acid treatment.
