Nano-Bond^® Nano-Particulate Reinforced Adhesive

Q. How does the Nano-Bond system work?
A. Nano-Bond self-etch adhesive is a 2-bottle system that effectively self-etches and primes dentin and cut enamel for bonding. A HEMA-containing primer etches without opening the tubules, removing post-operative sensitivity from the equation. Next, a nano-particle reinforced resin infiltrates the etched surface and provides a strong interface. The combination provides strong bonding to dentin and cut enamel. Uncut enamel does require etching prior to bonding with Nano-Bond adhesive.

Q. Will Nano-Bond self-etch adhesive work with both dual-cure and self-cure resin materials?
A. Yes, but only when Nano-Bond dual-cure activator is mixed with Nano-Bond resin. The resin and dual-cure activator should be mixed 2:1 (resin: dual-cure activator).

Q. Why is a syringe of phosphoric acid etch included with this kit?
A. Uncut enamel requires a 37% phosphoric acid etch before the Nano-Bond self-etch primer can be applied. This is necessary to ensure bonding to uncut enamel. A separate acid etch is not required for dentin or cut enamel.

Q. What makes Nano-Bond self-etch adhesive unique?
A. The Nano-Bond system contains polyhedral-shaped, surface-functional nano-particles. This new technology bridges the property space between hydrocarbon-based plastics and ceramics. These structures are characterized by their 3 dimensional, “cage-like” molecular shapes, which increases flexural modulus and hardness while maintaining the stress and strain characteristics of the base resin.
