No, not really.  The sort of teeth that T. rex had were not much
good for a gripping bite - just a quick slashing bite.  You are
more used to the more complex, multi-pronged, teeth of mammals,
which *can* grip while biting.

Thus, to immobilize prey *at *all*, dinosaur predators needed

This is, indeed the most likely reason for T. rex's arms.

Note, this is useful not onmly to protect against goring from
Triceratops (or its earlier cousins), but also to allow more
time to deliver the killing bite, and to make sure the prey
is still accessible when it dies.
