Braces correct the position of teeth and jaws. A dentist may recommend them to straighten crooked teeth, change spacing between teeth, or correct a malocclusion.
How self-ligating braces differ from traditional braces
Braces are devices that are attached to teeth. A thin metal wire called an archwire passes through the slots of the brackets. The archwire is gradually adjusted to apply force, moving teeth into the desired position. For braces to work effectively, the archwire must remain secured in the brackets.
Traditional braces achieve this using elastic bands or metal ties (ligatures). Ligatures visually enlarge the braces and make the archwire fixed. As teeth move into the correct position, ligatures need tightening with elastic ties monthly or more often.
Self-ligating braces use a built-in system to hold the archwire. Clips or sliding mechanisms hold the wire in place while allowing slight mobility.
Types of self-ligating braces
There are two types of self-ligating braces: active and passive. Both types use a locking mechanism.
Active braces have a mechanism that presses on the archwire and moves teeth faster. Passive braces secure the archwire but do not press on it, affecting teeth more slowly and making treatment more comfortable.
Like traditional braces, self-ligating braces require periodic adjustments. During adjustments, the orthodontist evaluates alignment progress and may replace the archwire. Adjustments can change the force applied to teeth, helping them gradually move into a new position.
Self-ligating braces are made from metal or transparent ceramic material. Sapphire braces also exist. Sapphire and ceramic braces match tooth enamel color, although the archwire is still metal.
Ceramic and sapphire braces look more aesthetic. Ceramic braces are made from material matched to enamel shade, while sapphire braces are made from transparent sapphire crystals. However, the archwire is metal in all cases.
Depending on placement, self-ligating braces can be:
- Vestibular (attached to the outer side of teeth)
- Lingual (attached to the inner side of teeth)
Self-ligating braces are primarily suitable for:
- patients who are more sensitive to oral discomfort;
- patients who cannot sit still in the dental chair for a long time.
However, like traditional braces, self-ligating braces can cause discomfort, especially after placement or adjustment. In some cases, they may cause less discomfort than traditional braces if proper oral hygiene is maintained.
Advantages of self-ligating braces
Potential advantages include:
- Shorter orthodontist visits: Traditional braces require ligature replacement; adjustments for self-ligating braces take less time.
- Easier cleaning: Ligatures can trap food particles; absence of ligatures makes cleaning easier.
- Less discomfort: Many patients may experience less discomfort compared to traditional braces.
Are self-ligating braces faster and more effective?
Current research does not confirm this claim.
Treatment duration largely depends on the specific case. A 2011 study comparing self-ligating and traditional braces in 62 people found no difference in treatment duration.
However, self-ligating braces may accelerate certain treatment stages. A 2019 study of 30 patients showed faster alignment of upper teeth during the first 4 months with self-ligating braces.Another important factor is long-term stability after treatment.
A study of 60 participants showed no difference in long-term stability between traditional and self-ligating braces. A 2017 review also found no significant differences in effectiveness.
Are there any risks?
There are some potential risks associated with self-ligating braces. One of them is bracket breakage. It is entirely possible that repeated opening and closing of self-ligating brackets can lead to wear. If a bracket needs to be replaced, this may increase the duration of treatment. Other risks associated with self-ligating braces are similar to the risks of traditional braces:
- Caries: food particles can get trapped in any type of braces, which can cause plaque formation and increase the risk of tooth decay;
- Relapse: if you do not wear a retainer after the braces are removed, it is quite possible that your teeth will begin to move back to their previous position.
Cost of self-ligating braces
Self-ligating braces usually cost more than traditional braces due to more advanced technology. Other factors include correction complexity and treatment duration.
Self-ligating braces use a built-in mechanism to hold the archwire. Patients may have shorter orthodontic visits, easier hygiene, and less discomfort. However, research currently shows no significant difference in effectiveness between traditional and self-ligating braces.
