I will be speaking to a group of orthodontists, some of whom refer to me. I know our position on rakes, cribs, etc. I looked in the literature and could not find any articles to tell me why orthodontists use these. Is it because they believe it is the best way to close the bite? Do they feel it is a more convenient and easy way to address open bites? Why do they opt for this? Is it based on research and training?
