I'm just looking at some photos now of a Maryland bridge. I don't think it's that one, as that's showing the fake tooth being attached at the back to both of the teeth on either side of the gap.
Mine is just attached to the back of the adjacent front tooth, so it's only attached on one side.
EDITED:
Just seen it can be attached with just one wing.
I've just been doing my research.
Yes then, I have a Maryland bridge, attached with one wing.
