At Wiesemann Orthodontics, we understand that braces can look pretty intimidating at first glance. There are a lot of pieces involved, and it’s not always obvious what each one does.
The good news is that Dr. Wiesemann and the rest of the team know this system inside and out. Whether you’re looking at traditional metal braces, ceramic braces, lingual braces, or self-ligating braces, every part has a purpose. Here’s a breakdown of what you’ll find and what each component actually does.
Brackets
Brackets are small metal squares bonded directly to the front and side teeth using a special adhesive. They act as anchor points that give us something to work with when guiding teeth into position. Most brackets are made from stainless steel.
Clear Brackets
Clear brackets work the same way as metal ones, but they’re made from a ceramic material that blends in with the natural color of your teeth. A lot of patients prefer the more subtle look they provide.
Bands
Bands are metal rings that fit around the back molars. They have a small metal attachment welded to the outside that allows the archwire to connect. Like brackets, they’re secured to the teeth with an orthodontic-grade cement.
Worth clearing up, since it confuses a lot of patients: people use the word bands for two completely different parts. These molar bands are one. The small rubber bands that go around each bracket are the other, and we get to those further down.
Buccal Tubes
The bracket on your very last molar isn’t really a bracket at all. It’s a buccal tube, a small metal tube welded onto the molar band or bonded straight to the tooth. The end of the archwire slides into it and anchors there, which is what gives the rest of the wire something to push against. Buccal tubes usually have a small hook on them too, which is where elastics attach when your treatment calls for them.
Archwire
The archwire is the wire that runs through all the brackets and bands. It’s really the driving force behind tooth movement, applying steady, gentle pressure that guides teeth along the path Dr. Wiesemann sets. As teeth shift, spaces close and alignment improves based on the specific bends built into the wire.
Power & Energy Chain
A power chain is a row of connected rubber O-rings that stretches across a group of brackets. As it tries to retract, it pulls the teeth together and helps close spaces along the archwire. Power chains come in grey, clear, or a variety of colors, and Dr. Wiesemann’s team swaps them out at each visit. Feel free to pick a new color every time you come in!
O-Rings
O-rings are tiny rubber rings placed around each bracket to keep the archwire secured. They’re available in clear, grey, or other colors.
If you have self-ligating braces, you won’t need O-rings, since those brackets have a built-in clip that holds the wire on its own. Lingual braces are a different thing entirely. They mount behind the teeth instead of in front, and depending on the system, they may still use O-rings.
Types of Rubber Bands
When it comes to rubber bands for braces, there are actually two distinct types: ligatures and elastics. Depending on your specific treatment plan, Dr. Wiesemann may use one or both. Either way, today’s orthodontic bands are far more comfortable and refined than what most people picture from years past. If you want the full picture on how elastics work and why wearing them matters, we cover that in our guide to what rubber bands do during braces treatment.
Type #1: Ligatures
If your treatment plan includes traditional metal or ceramic braces, it will include ligatures. These small bands are woven around each bracket to hold the archwire in place with the right amount of tension. They’re one of the most essential parts of the whole system.
Over time, ligatures stretch and wear down, so they’re replaced regularly using a small tool called a Mathieu Plier. Usually at least one or two get swapped out during a monthly visit, and the full set is replaced when a new phase of treatment begins.
At Wiesemann Orthodontics, we offer a range of color options for ligatures. Ask about your favorite team or school colors and we’ll make it happen!
Type #2: Interarch Bands (Elastics)
Interarch bands, also called elastics, are used in cases involving an overbite or underbite. Rather than being woven into the bracket system, they attach to hooks at specific points on the upper and lower brackets and stretch between the two jaws. This creates targeted pressure to help correct your bite over time.
Dr. Wiesemann will position the bands based on your particular bite issue. Unlike ligatures, interarch bands are removable and should be taken out when brushing, flossing, and sometimes eating, depending on your instructions.
When used consistently, they can make a real difference in your results and may even shorten overall treatment time.
Braces Parts FAQs
What is the last bracket on braces called?
It’s called a buccal tube. It sits on your back molar, either welded to a molar band or bonded directly to the tooth, and the end of the archwire slides into it. That’s what anchors the wire so it can move the teeth in front of it.
What are the main parts of braces?
Brackets, molar bands, buccal tubes, the archwire, ligatures, and elastics. Some treatment plans also use a power chain to close spaces. Self-ligating braces skip the ligatures and use a built-in clip instead.
What is the difference between braces bands and rubber bands?
Braces bands, or molar bands, are the metal rings cemented around your back teeth. Rubber bands are the small elastic pieces, either the ligatures holding the wire to each bracket or the interarch elastics stretching between your upper and lower jaw.
Do all braces use O-rings?
No. Traditional metal and ceramic braces use them to hold the archwire against each bracket. Self-ligating brackets have a clip built into them, so they don’t need O-rings at all.
