I know this is the state of the art for posterior composite restorations with Apex Dental Materials products. The goal is to very efficiently produce an excellent quality restoration. In this case I'm using Clean and Boost, Surpass 1,2,3, Titan A2 Flowable, Seamfree and Exquisite. I'm curing each increment for 3 seconds only with my Valo light set on XTRA POWER, or 3200mW/cm2.The increments are as thick as 4 mm's each, and I'm placing 3 increments only. After the restoration is finished and the occlusion is adjusted, I'm sealing the surface with a quick, thin coat of Surpass 1,2,3.
This is an efficient technique with less than 30 seconds spent actually light curing. We only know that this can be done with Exquisite, and that's due to its’ low amount of shrinkage (less than 2%) and the composition of the resin molecules. The layers we're curing are up to 4 mm's thick. With shallower preps than this we've been able to bulk fill the prep and cure the whole thing for only 3 seconds. I tend to spend more time adjusting those cases so I prefer this layering technique.
