Alloybond both desensitizes and bonds to the amalgam. Alloybond is Southern Dental Industries' high strength adhesive system for bonding amalgam restorations to enamel and dentine. Amalgam bonding increases the amalgam restoration's strength. Amalgam bonding reinforces the remaining tooth structure and increases fracture resistance. Amalgam bonding reduces the need for sound tooth structure removal.
Amalgam bonding decreases micro-leakage and thus recurrent caries.
Amalgam bonding decreases or eliminates postoperative sensitivity. A self cured bond, such as Alloybond, interlocks with the amalgam. Alloybond seals and can be placed in roughly the same time as a liner, but Alloybond also bonds the amalgam. The Alloybond Primer is composed of acetone and hydrophilic and hydrophobic monomers, designed for mechanical and chemical adhesive, providing long term microleakage protection. The Alloybond Base and Catalyst combine to form resin tags within the amalgam, mechanically interlocking for retention.
