Study Notes
Types of Orthodontic Appliances
-
Fixed Appliances: bonded to teeth, cannot be removed by patient
- Brackets (metal or ceramic)
- Bands (metal rings around teeth)
- Wires (archwires, ligature wires, and coil springs)
-
Removable Appliances: can be removed by patient
- Clear aligners (e.g. Invisalign)
- Removable retainers
- Hawley retainers
- Elastic separators
Components of Orthodontic Appliances
-
Brackets: attached to teeth, have a slot for the archwire
- Types: stainless steel, ceramic, plastic, or self-ligating
-
Archwire: connects brackets, applies force to teeth
- Types: round, rectangular, or square
- Materials: stainless steel, nickel-titanium, or beta-titanium
-
Ligatures: hold archwire in bracket slot
- Types: elastic, wire, or self-ligating
-
Bands: metal rings around teeth
- Used for molars or anchorage
Functions of Orthodontic Appliances
- Tooth Movement: applying force to move teeth into correct position
- Retention: holding teeth in place after treatment
- Anchorage: resisting unwanted tooth movement during treatment
- Space Closure: closing gaps between teeth
