You can provide any good quality hay to bunnies, no reason why mini-lops would be any different to dutchies or any other shaped bunny.
However, where a bunny may be more prone to dental problems, I will always give them a courser hay such as timothy and rye (which I get by the bale and is grown locally) It's very stalky and takes quite a bit of effort for the bunnies to get through. Most of mine prefer it to the meadow hay, which I get from the same farm.
Mini-lops have been bred to produce a particular flatter head shape and it therefore follows that they are thought to be more likely to have some dental issues, along with other lops and dwarfs. I would just ensure that your mini has unlimited hay and if possible make sure that the stems are not chopped (as you get in shop bought bags) but are long and stalky. This will give your bunny's teeth a real workout. But, it isn't so important, just provide good hay and you'll be fine.
