Just look look closely with the microscope if the pad was really connected to anything..

Some IC pads just come off because they are simply not even connected to any track anyway

So for those you dont even need to restore them.

Okay so To resore a missing pad, just dig out the hole gently with a sharp scalpel knife point till you reach the second board layer where the pad was connected at.
Now fill the hole with soldering paste and heat it.
Tadaaa! A nice new pad is created.
