Are your front teeth too inward / too retracted / too retruded? You might be able to improve your teeth angulation. Ask me how!

hey doctor weird question but when some orthodontists say powerchains move teeth -1mm retraction per month do they mean the teeth going literally backwards in the bone 1mm? (talking about front 4s)

Not a weird question at all. In your example of premolar extraction, the size of the premolars is generally 7mm. I usually average about 0.75mm per month (for teenager) of retraction so it usually takes me 9-10 months to close spaces for a teenager and about 12-14 months for an adult. Second question, YES ... it means the entire tooth is being retracted. It's probably less than 1mm because of reciprocal forces, but in terms of simplicity ... 1mm is a commonly used measurement term but it's really more like 0.6-0.8mm/mo.
