    Symmetric or asymmetric molar distalization is readily accomplished using a removable appliance, the acrylic cervical occipital (ACCO) appliance. Movement occurs at the rate of approximately 1 mm per month with considerable individual variation. Molar movement is primarily tipping, requiring some overcorrection to allow for subsequent uprighting.
