Hi John,
A new impression would defineately be required in order to construct a new retainer for you, x-rays would not be useful in this case unfortuneatly.

Further to the other answer about the x-rays not being useful for a new retainer:
Unfortunately a retainer does not move the teeth back to their position. New moulds, or impressions, taken would only hold the teeth in their current position. To move them back you would need to restart the braces process.
If you get new retainers made, make sure that you get new ones immediately should you lose or break them.
