"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. Indications:- All direct, light-cured bonding procedures. Indirect bonding procedures when combined with 3M? ESPE? RelyX? ARC Adhesive Resin Cement. Root surface desensitization. Porcelain and composite repair. Bonding veneers in combination with RelyX? Veneer Cement from 3M ESPE."
