A lot depends on the depth of impaction. If the tooth is not too deeply impacted, it can be dis-impacted (i.e. freed) using some sort of orthodontic brace. Before we embark on treatment for an impacted tooth, we have to assess whether the tooth would be useful when it is dis-impacted. Does it have an opposing tooth in the other jaw to chew against? Is there space behind to tip the wisdom tooth back to dis-impact it? Is the wisdom tooth accessible to the orthodontist? If there is tooth much gum over the wisdom tooth, you may need to wait for the gum to uncover the wisdom tooth. If it is inaccessible, it would be difficult to attach an orthodontic bracket on the tooth.
