Acer iconia one 10 tablet touch screen became unresponsive when my nephew dropped it

My nephew dropped his tablet (which was already kind of damaged/cracked) and now 95% of the touch screen doesn't work. I tried restarting it and then tried tapping all over the screen, and got one corner to be responsive. I doubt there's anything that can be done, but maybe someone here has some potential tips to possibly fix an unresponsive tablet touch screen.
