Class II elastics are small orthodontic rubber bands worn between the upper and lower teeth. They are commonly used with braces or clear aligners to help correct a “Class II” bite relationship. In plain terms, they guide the upper and lower teeth (and sometimes the jaws) toward a better fit. They are typically hooked from an upper canine area to a lower molar area, depending on the plan.

interarch elastics are small orthodontic rubber bands that connect the upper and lower teeth. They are commonly used with braces or clear aligners to help guide how the jaws and teeth fit together. They attach to hooks, buttons, or cutouts on orthodontic appliances to apply gentle pulling forces. Their main role is to refine the bite relationship during orthodontic treatment.

rubber bands are small elastic loops used in dentistry to apply gentle, controlled force or to hold components in place. They are most commonly associated with orthodontics (braces and some aligner systems). They can also be used for short-term tasks like creating space between teeth or stabilizing orthodontic parts.

elastics are small, stretchy polymer bands used in orthodontics to apply controlled forces to teeth and jaws. They are commonly worn with braces or clear aligners by hooking onto attachments in the mouth. Their main role is to guide tooth movement and bite correction by pulling in specific directions. They may also be used in related forms (like elastic chains) to help close spaces or maintain tension.

A ligature tie is a small orthodontic fastener used with braces. It helps hold the archwire (the main wire) into the bracket on a tooth. It is commonly made from an elastic ring or a thin metal wire. It is most often used during routine orthodontic adjustments.

A steel ligature is a thin stainless-steel wire used most commonly in orthodontics. It is typically twisted to tie an orthodontic archwire into a bracket slot on braces. It can also be used to secure small orthodontic accessories, depending on the treatment plan. In simple terms, it is a metal “tie” that helps hold orthodontic parts in place.

An elastic ligature is a small elastic ring used in orthodontics to help hold an archwire into a bracket on a tooth. It is most commonly seen with traditional braces, where it sits around the bracket “wings.” It can be clear, colored, or formulated for specific handling or friction characteristics. Its main role is mechanical: keeping the wire engaged so planned tooth movement can occur.

A ligature is a small tie used to hold something in place in the mouth. In orthodontics, a ligature commonly secures an archwire to a bracket on a tooth. Depending on the type, it can be an elastic ring, a small wire tie, or a preformed module. The term can also be used more broadly in healthcare to mean “a tie,” but dental use most often refers to orthodontic appliances.

A **wire sequence** is the planned order of orthodontic archwires used during braces treatment. It describes how clinicians typically progress from more flexible wires to stiffer, more controlling wires. wire sequence is most commonly discussed in **fixed appliances (braces)**, but the concept also applies to some adjunctive orthodontic mechanics. The exact wire sequence varies by clinician and case.

round wire is a thin, cylindrical metal wire used in dentistry, most commonly in orthodontics. It is often used as an archwire in braces or as a component of retainers and other appliances. Its round shape helps it slide and flex in predictable ways during tooth movement or stabilization.
