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.
rectangular wire is an orthodontic archwire with a rectangular or square cross-section. It is commonly used with braces by fitting into the rectangular “slot” of brackets. Its shape helps the orthodontic appliance control tooth angulation and root position. It is most often introduced after early alignment stages, depending on the case.
TMA wire is an orthodontic archwire made from a titanium–molybdenum alloy (often called “beta-titanium”). It is used in braces to guide tooth movement by delivering controlled, elastic forces through brackets and tubes. Clinicians often choose TMA wire when they want a wire that can be bent and customized more than some other wire types. You may hear it mentioned during mid-treatment adjustments, space closure, or detailed finishing steps.
A beta-titanium archwire is an orthodontic wire used with braces to guide tooth movement. It is commonly chosen when clinicians need a wire that can be shaped precisely while still delivering steady force. It is often described as “workable” because it can be bent into detailed shapes for specific mechanics. It is used in many stages of orthodontic treatment, depending on the case and clinician preference.
A stainless steel archwire is a metal wire used in orthodontics to guide tooth movement. It sits in the slots of braces (brackets) and is secured with ties or clips. It helps apply controlled forces to align teeth and coordinate the dental arches. It is commonly used during braces treatment and sometimes as part of retainers or space-maintaining appliances.
