We fit these once the fixed appliances have
been removed, to keep the
teeth in their corrected positions for at least a year afterwards.
Patients normally have a combination of an upper removable appliance
and a wire
fixed onto the back of the lower teeth, although this can vary.
Removable retainers are normally worn all the
time for the
first few weeks, and then on a part time (eg night time) basis. They
sometimes be in the form of a clear plastic splint like the patient in
left picture is wearing. These are virtually invisible and very easy to
but are not suitable for every case and do break much more often.
