ligature |
|
an orthodontic appliance, fixed or removable, used to maintain the position of the teeth following corrective treatment |
retainer |
|
a removable plastic and wire appliance used to stabilize teeth; may be modified for special applications during or after orthodontic therapy |
hawley retainer |
|
prosthetic replacement for prematurely lost primary teeth to prevent closure of the space before erruption of the permanent successors |
