If you really want to restore it you can use something like Black Door by Riccardo Berdini to do so but this trick is not a torn and restored card effect.
If you start by pointing that out that this is not a torn and restored card trick at the beginning of the trick it can be all the more mysterious initially. Why else would you tear a card? If you explain that it is not a torn and restored card trick you are less likely to have the question at the end of the routine.
