It was once very difficult to effect rotation of a molar or bicuspid using a removable device. The Combination Fixed-Removable Appliance has solved the problem. Direct bond buttons can be placed on just those teeth needing rotation, with hooks for elastics placed wherever they are needed on the removable appliance. Using a mirror, the patient can easily learn to hook up the elastics. Note: Well-designed finger springs can also be added to afford other needed corrections. In this case, a combination finger spring/direct bond button is used on the right cuspid to aid in its eruption and distal positioning as the first bicuspid is rotated.
