Nony above me:

The avatar (Aang) has been the only one known person to take be able to tale a person's bending away permanately. However, in the time before the avatar, people were energybenders.

So, anyone, given the power, can take a person's bending away permanently (i.e. Lion turtle). It's just that the time before the avatar has been forgotten by the modern world, so that it would seem like only the avatar posesses that ability, since that knowledge was lost to everyone else. But anyone can do it.
