Removable Appliance
An orthodontic device that the patient can insert and remove, used for simple tooth movements or as a retainer.
Full Definition
A removable appliance is an orthodontic device designed to be worn in the mouth but taken out by the patient for cleaning and eating. It typically consists of an acrylic baseplate, wire clasps for retention, and active components such as springs or screws that deliver controlled forces to individual teeth. Removable appliances are distinguished from fixed appliances (brackets and archwires bonded to teeth) by their limited ability to achieve complex three-dimensional tooth movements. They are widely used in early interceptive treatment and as retention devices post-treatment.
Usage
Usage note: Do not hyphenate 'removable appliance' as a noun phrase. When used as a pre-modifier, hyphenation is optional but should be consistent throughout the document.
