While replacement hangers are available, more often than not, they are able to be bent back with relative ease. The hangers are made out of a soft metal that allows them to bend under impact to protect the derailleur. They can be bent back with very minor loss of strength and can work for decades after being realigned.
The following link goes over this process and how to realign your hanger, any local bike shop would also be familiar with this process.
