What is the purpose of orthodontic elastics?

What is the purpose of orthodontic elastics? According to dentists, not every orthodontic case requires the use of elastics. Additionally, the effectiveness of orthodontic elastics varies depending on the condition of the teeth. Here are some common purposes of orthodontic elastics:

For crooked teeth:

In cases of crooked teeth, teeth growing in the wrong direction, or teeth tilting upwards, using elastics is very suitable. Patients will wear the elastics every day, and with consistent pulling force, the teeth will gradually move into the correct position.

For overbite:

In this case, the elastics will be placed diagonally between the upper and lower jaws, specifically placing the elastics from the front of the upper jaw to the back of the lower jaw. This action will simultaneously help pull the upper jaw inward and push the lower jaw outward, creating a balanced arch for the patient’s teeth.

For bite alignment issues:

If you are experiencing bite alignment problems such as an open bite, crossbite, or misaligned bite, orthodontic elastics are definitely a tool you should use during the jaw alignment process. The elastics will exert pressure on the braces, adjusting the position of the teeth and improving conditions related to the jawbone.

The duration of wearing orthodontic elastics depends on the condition and treatment plan prescribed by your orthodontist. The success of this method will be reflected in achieving a balanced bite and proper tooth alignment.

Elastics chain

This is a type of appliance specifically used for cases of spacing between teeth. The dentist will attach each end of the elastic to the brackets, and the force exerted by the elastic will bring the gaps between the teeth closer together. Therefore, elastic chains have relatively high elasticity.

Interarch elastics

Interarch elastics are used on the teeth by using a type of elastic with good elasticity, attaching it to the brackets on the upper and lower jaws corresponding to each other. This action creates a stable pulling force on the teeth, helping them quickly return to their correct positions within the jaw, addressing dental issues.

With these effects, different types of interarch elastics also help shorten the patient’s orthodontic treatment time.

Why use orthodontic elastics in orthodontic treatment?

It is necessary to use various types of orthodontic elastics in orthodontic treatment because they are an important component in determining the results of the braces method. Specifically, orthodontic elastics have the following functions:

  • Orthodontic elastics create additional pulling forces along with the archwire to move the teeth to the desired positions more quickly. Additionally, these elastics help the position of the upper and lower jaws to fit closely together and improve the bite.
  • Orthodontic elastics physically pull misaligned teeth upwards towards the upper jawbone or pull rotated teeth into their correct positions, achieving proper alignment.
  • In cases of overjet (protrusion), orthodontic elastics are placed from hooks on the upper jaw to hooks on the lower jaw, pulling the upper teeth backward. Simultaneously, these elastics also help pull the lower teeth forward, achieving more even tooth positions.
  • In cases of crowding, the orthodontist will use elastics to apply the right amount of force on the upper jaw to move the teeth to the desired position.

Orthodontic elastics have very beneficial effects in orthodontic treatment. Therefore, depending on each individual case, orthodontists will prescribe the use of elastics according to the specific treatment plan.
