Snapped a seedling...is there hope?

I dropped my reflector on some of my seedlings today. Luckily only one of them actually snapped. It snapped in two places about an inch away from each other. The plant was not totally severed. I folded the plant down and put new dirt over all of it but the top inch. Is this the right thing to do? Should I add some superthrive?
