Can I fix a dent in the back?

My son stepped on my IPad 12.9 - 3 when it was face down and in it’s case. The screen isn’t broken but the dent in the back in making 1 inch of the screen black. If I open it up can I somehow bend the dent out and if I did, will that fix the screen issue it is causing?

Thanks so much Jesse. It’s not causing a black spot but rather a black line across the screen. I’m wondering if I bought small suction cups could I pull the dent out and if I did, would that fix the black line?
