A removable appliance is made up of an acrylic plate with wire clasps on the sides, which grip the teeth to keep the brace in place. It can be taken in and out by the patient. Removable appliances have a limited number of uses, mainly because they are restricted to moving individual teeth and widening either the upper or lower arches. They can also be used as space maintainers to allow permanent teeth to erupt without loosing the space for them. It is important to understand that, it isn’t a precision appliance and cannot be used for complicated or fine detailed tooth movements.
