Always challenging are the back to back composites. This is 29 DO / 30 MO done in Surpass and Exquisite with my Valo light on XTRA POWER, or 3200 mW/cm2 (aka "plasma mode").We are working on techniques to speed up these procedures and still get excellent results. With Exquisite we can cure to a 4 mm depth, so we don't need any more than 3 layers, and each one cures as completely as possible with only 3 seconds of light initially and 3 more seconds from each direction at the completion.
We're working on speeding up these restorations while maintaining excellent results. Because of Exquisites low rate of shrinkage and very low shrinkage stress we're curing with the Valo light on it's highest setting, yet there are no white lines, aka enamel margin fractures, forming and we're getting as complete of a cure as is possible. We know that with Exquisite in small preps you can "bulk fill" the whole prep. But it's easier to develop good occlusal contours when we fill the buccal and lingual halves separately.
