The Optibond™ (Kavo/Kerr) family of bonding agents boast what many would still agree are one of the gold standards in dental adhesion. Their two bottle bonding agents are still around, regardless of the one-bottle “Universal” bonding agent surge, because they just plain work well. Building on these most recently prompted the development of Optibond™ eXTRa Universal.
Here at the Dental Advisor, we recently received Optibond™ eXTRa Universal. The manufacturer claims that this two-bottle universal bonding agent can be used with self-etch, total etch, and selective etch techniques. 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.
What is head turning about this material are the great bond strengths. Testing in the Dental Advisor bio-materials lab not only confirmed the manufacturer’s claims of bond strengths to self-etched enamel, self-etched dentin, zirconia and lithium disilicate substrates, but also showed better bond strengths!
What were the Initial Insights of the Dental Advisor team and our editorial board?
– The great bond strengths this product possess might make it worth the extra time.
– The adhesive has a little thicker film thickness.
– The primer has to be scrubbed 20 seconds and air thinned 5 seconds followed by the adhesive being brushed for 15 seconds and air thinned 5 seconds prior to light curing.
