Bands :
1. Definition of Orthodontic Band
An orthodontic band is a thin metal ring that fits around a tooth (usually molars or premolars) and serves as a base for attaching brackets, tubes, or other orthodontic appliances.
Features:
-
Usually made of stainless steel.
-
The inner surface may have grooves or adhesive to hold a bracket or tube.
-
Size and shape are selected according to the patient’s tooth.
2. Types of Orthodontic Bands
A) Based on Tooth Position
Molar Band:
-
Designed for large and strong molars.
-
High resistance to pulling and rotational forces.
-
Often used as a base for buccal tubes and auxiliary appliances.
Premolar Band:
-
Smaller and narrower than molar bands.
-
Used to hold wires and sometimes special brackets.
Anterior Bands:
-
Rarely used and mainly for holding special orthodontic appliances on front teeth.
B) Based on Application
Conventional Band:
-
Metal, uncoated, with inner grooves for a bracket or tube.
-
Most common type for classic orthodontic treatment.
Welded Band:
-
Used to attach auxiliary components such as special tubes or ceramic holders.
Coated Band:
-
Nickel- or tooth-colored coating for aesthetics and to reduce visibility of metal.
Functional Band:
-
Used for installing auxiliary appliances such as expanders or headgear.
3. Important Considerations When Selecting a Band
-
Size: Should fit snugly—not too tight or too loose.
-
Strength: Must withstand the pulling and twisting forces of wires and appliances.
-
Coating & Allergy: Some patients are sensitive to nickel, so nickel-free or coated bands are recommended.
-
Adhesion: If a bracket or tube is needed, the inner groove or adhesive should be suitable.
4. Procedure for Using Bands
-
Select a band of the appropriate size.
-
Trial fit on the tooth.
-
Use temporary wiring or adhesive for placement.
-
Permanent placement with cement or adhesive.
-
Check stability and patient comfort.
