This is a great use of Injectafil. Patient from China with very crowded Class 2 div 2 and uneven occlusal planes. She's finally going to ortho next week. 15 is supraerupted and has contact with 18 on the mesial side of the mesial marginal ridge, pushing 15 distally for a very efficient food trap. Of course that means decay at the CEJ. I'm using Injectafil here because I can bulk fill it and since it's dual cure I don't have to worry about too little or too much light curing.
Using Injectafil made this case relatively easy as I didn't have to worry about layering and curing. I could have gone back and placed a second Triodent matrix, adding more composite to close that contact (did that yesterday for another tough one). But she's off to ortho next week so there's no need.
