tibook hinges

When re-soldering the inverter cables on my Tibook's display...I forgot I had a screw out, slid the lcd back, and the small part of hinge right underneath the mount snapped off...its only about a 1/2 an inch long, and the screen still feels compeltely steady when I open and close it, I was just wondering how integral this part is to the display, and whether or not its really gonna affect anything, seeing as its just the part at the bottom.

thanks all!
