If it helps at all, Arnett & Gunson train and work with orthodontists who follow the Roth Williams/FACE treatment philosophy.
But I'm not sure how it works - i.e if you were to go with a Roth Williams/FACE trained-ortho if you must also work with a surgeon who follows that philosophy too (for best results), and vice versa. I'd guess so.
"The RW FACE philosophy is unique from other orthodontic treatment methods because it involves multiple dental specialties in treatment planning and diagnosis while emphasizing three basic principles. These include a focus on developing smile aesthetics based on genetic morphology; functional occlusion for facial balance, lip support, efficient chewing and healthy gum tissues; and proper joint function for lifelong stability."
Where are you from? It seems to be more popular in US, Brazil, Spain, Italy, Portugal and maybe some other parts of Europe.
