This is replacing a worn out occlusal composite on 31 done as fast as I want to go. I could have gone faster if I'd bulk filled, but I'm OCD about anatomy and bulk filling doesn't make that easy, or even possible, for me. Here I'm using Clean and Boost, Superb, WO Titan Flowable, Seamfree, and Exquisite.
That's as fast as I can go and still get the quality restoration that I want. You can go faster with bulk filling (and I do that with smaller restorations) but with areas this large I spend much more time shaping the anatomy. This was not any longer than 20 minutes of my time even with all the photos.
