The Concept and Principles of Clear Aligners

Orthodontic appliances were tools used to align teeth properly, but visible metal appliances often interfered with social life. Clear aligners were developed to overcome these drawbacks. As the name suggests, clear aligners use orthodontic appliances made from transparent plastic material. These appliances are not attached to the teeth and can be freely removed and worn by the patient. Therefore, they are convenient because they can be removed when eating or brushing teeth, and they are also aesthetically excellent because they are not noticeable to others.

Unlike conventional braces, the appliances need to be replaced periodically as the teeth move, and they must be worn actively according to the dentist’s instructions in order to achieve the desired results. During the manufacturing process, 3D scanning technology was used to accurately assess the patient’s dental condition, and computer simulation was used to predict the path of tooth movement.

Features and Advantages of Invisalign

Invisalign is a type of clear aligner and is an orthodontic system developed by Align Technology in the United States. Euljiro Dental Clinic will also explain its main features.

  • Special material: It used a specially reinforced plastic material, giving it high durability and elasticity, and its thin 0.7 mm thickness reduced foreign-body sensation and provided a comfortable fit.

  • Precise adjustment: It could control minute amounts of tooth movement, making it applicable to various malocclusion cases.

  • Customized production: Using computer technology, it was custom-made to fit each patient’s dental condition, and it was highly trusted, with more than 9 million patients worldwide having used it.

  • Broad applicability: Unlike general clear aligners, it could move even molars, making it effective for extraction cases and complex orthodontic cases. Teeth were gradually moved by replacing the aligners with new ones every 6 to 8 weeks.

Then why did so many people choose clear aligners? Euljiro Dental Clinic will explain this in detail as well.^^

Excellent aesthetics

Conventional orthodontic appliances were attached to the teeth, which made them noticeable and less visually appealing. In contrast, clear aligners were made of transparent plastic material, so they were not easily visible, and because they could be removed, they caused less inconvenience in daily life such as eating and brushing teeth.

Convenience and time savings

The number of clinic visits was lower, which saved time and money. Conventional orthodontic treatment required visits every 4 weeks for appliance adjustments, but clear aligners only required visits every 2 to 4 months. In addition, the appliances could be cleaned, making them hygienic and making dental care easier.

Less pain and easier adjustment

Because they were made of a soft material, they caused less irritation to the teeth, and the discomfort felt when first wearing them was also minimal. They also did not interfere with pronunciation, so they did not disrupt social life. For these reasons, at the time, the number of patients preferring clear aligners also increased at Euljiro Dental Clinic, but it was still best to consult with medical staff before deciding whether it was the right case for treatment.

Invisalign treatment proceeded in the following stages:

  1. Planning and scanning stage

First, the oral condition was examined, and the path of tooth movement was identified through X-rays and dental plaster models. After that, a 3D oral scanner was used to create a digital image of the teeth.

  1. Appliance fabrication stage

Based on the digital images, the movement path of the teeth was calculated using Invisalign software, and custom clear aligners were fabricated accordingly. During this process, the post-treatment appearance could be previewed through computer simulation.

  1. Wearing stage

The fabricated aligners were worn in sequence. In general, it was recommended to wear them for 20 to 22 hours or more per day. They could be removed only when eating or brushing teeth.

  1. Visit and checkup stage

Patients visited the dental clinic periodically so the appliances could be adjusted and the movement of the teeth could be checked. Usually, they visited every 2 to 4 weeks, but the interval could vary depending on the speed of tooth movement.

  1. Completion and retention stage

When tooth movement was complete, the orthodontic appliances were removed and a retainer was worn. The retainer had to be worn for a certain period to prevent teeth from shifting back.

  3. Dietary precautions: While wearing the appliance, chewing food or eating hard foods should be avoided.
