Hi Cleo Wa, welcome to pets.ca!
I don't have any personal experience with stomatitis, but I do know that it can be a very frustrating condition to deal with. I've never heard of it referred to as a jaw bone disorder. It tends to be looked upon as an immune system disorder. As drastic as it sounds, from what I know from others who have been through this with their cats, sometimes pulling most of the teeth is the only option. Here are some previous posts on the topic:
