In the method, at least one leg of the hand instrument is placed along a tooth-facing side of the archwire and the instrument is manipulated in order to urge the archwire in a direction toward the latch. The archwire is pressed against the latch with sufficient force to open the latch and release the archwire from the archwire slot. The hand instrument preferably includes two legs with a cam section located between the legs. The cam section contacts the appliance while a shaft of the instrument is rocked in order to press the archwire against the latch.</p> |
