How Do Clear Aligners Work?

The world has changed so much in the past 20 years, from the Internet, to Smart Phones to Clear Aligners.

Technology has come a long way and changed the way we do almost everything and Aligners are no different.

When Aligners first came out, they were extremely limited in what they could do and only very minor tooth movements could be performed. This meant that the majority of patients would not be a good candidate for Clear Aligners.


Fast forward 20 years and the technology has improved significantly. Now most patients can be treated with aligners; however, there is a catch. In order for Clear Aligners to be effective in creating a beautiful smile, the patient must wear them responsibly for around 20-22 hours a day.

How Do Aligners Move Teeth?

Custom Fit: Aligners are custom-made for each patient using 3D computer imaging technology. This ensures that they fit snugly over the teeth.

Attachments and Pressure Points: Unlike braces, which use brackets and wires, aligners apply force through clear, removable trays. In addition, small composite tooth colored “attachments” are bonded to certain teeth to act as anchors. These attachments help to create specific pressure points which guide the movement of the teeth.

Gradual Movement: Each set of aligners is slightly different from the one before. You wear each set for about 1-2 weeks, and each set is designed to move the teeth incrementally. This gradual, controlled force moves the teeth into the desired position.

Sequential Planning: The entire treatment process is planned in advance using specialized software by the Orthodontist. This plan dictates the sequence of movements that your teeth need to undergo, and each set of aligners is created according to this sequence.

Consistent Wear: For aligners to be effective, they need to be worn 20-22 hours a day. They should only be removed for eating, drinking anything other than water, and brushing teeth.

Biomechanical Principles: The force applied by aligners is based on principles of biomechanics. The aligners exert pressure on specific teeth, and the force is designed to stimulate cellular responses in the bone and periodontal ligament. This allows the teeth to move while the bone remodels around them.

Board Certified Orthodontists Dr. Nee & Dr. Cyrus in Escondido have taken specialized masters courses focused on specifically moving teeth with clear aligners.
