Trying to keep track of bonding agent generations can make your head spin. Generations used to be based on number of bottles and what was in them. Now, with all the variations of “Universal” bonding agents, generation determination made a switch to being based on the indications of the material.

Optibond™ Universal (Kavo/Kerr) is an 8th generation bonding agent. What does that mean? It simply means it does it all, and all in one bottle. Looking to save some time and money all while not having to second guess if your bonding agent will also prime your ceramics and work with dual cure materials? Look no further than an 8th generation bonding agent.

Building on the long line of the Optibond™ family, Optibond™ Universal promises to simplify your bonding procedure and make it less technique sensitive. The manufacturer claims that this material can be used with self-etch, total etch, or selective etch techniques. They boast a thin film thickness of only ~5 microns. As shown in the selection guide below, it can be used with dual cure materials, without the need of a separate activator, direct restorations, and indirect restorations. There is one caveat to the indirect restorations. When using with metal based substrates (which they include zirconia and alumina based) or posts they state you should use only with NX3/Maxcem (yes, their proprietary brand) cements.

What were the Initial Insights of the Dental Advisor team and our editorial board?
– Extremely thin film thickness that had excellent wettability.
– No need to air thin, just a quick 5 second dry to evaporate the monomer (after your 20 second scrub).
– Claims to adhere better to self-etched enamel. We are excited to see what the evaluators find. 
– Testing in the Dental Advisor lab confirmed good bond strengths to self-etched enamel, self-etched dentin, zirconia, and lithium disilicate substrates.
– A one bottle system is going to give convenience but no matter the system, you are going to loose some bond strength in exchange.
– The smell seemed a little strong.

What do our Clinical Evaluators and their patients think about this product once it’s used in their offices? Look for our clinical evaluation in an upcoming issue!
