We’ve witnessed adhesive resin bonding agents evolve from fourth generation to eighth (or universal) generation, and from two bottles to one bottle. GC has recently introduced G2-Bond Universal, a unique two-bottle system using proprietary Dual-H technology. Are we reverting to the old standards? Not in the least! In fact, there are distinct advantages to this two-bottle system that will appeal to all dentists.
First, there is the ability to either self-etch (SE) or use an etch-and-rinse (ER) technique. With either method, you get a highly effective seal with a shock-absorbing bonding layer (due to its flexural strength) and no post-op sensitivity. Consequently, you can confidently seal and repair existing restorations as well as use for initial restorations, creating a high bond strength to dentin, enamel, and all restorative substrates. G2-Bond Universal has a unique dispensing system whereby you apply the hydrophilic 1-Primer component first to wet and etch the tooth surface and then apply the 2-Bond component, which provides a highly hydrophobic bond layer to facilitate stronger bonding to the restorative material. Together this system significantly reduces the risk of gap formation and debonding, helping to maintain a high-quality margin over time. The composition includes 4-MET for reliable adhesion to both dentin and enamel; MDP for increasing adhesion and allowing for bonding to zirconium, alumina, and nonprecious metals; MDTP for bonding to precious metals; and it is HEMA-free. This is a great product not only for bonding of composite and compomer restorations, but also for dual-cured composite core buildups, intraoral repair of composite, metal-based and zirconium/alumina restorations, treating dentinal hypersensitivity due to exposed tooth surfaces, and cementation of all types of restorative crown and bridge substrates using G-Cem LinkForce. When it comes to one bottle versus two bottles, it seems like GC figured out that taking a step back will actually allow us to move forward!
