How Clear Aligner Works

Clear Aligners work like other orthodontic appliances — they use pressure that slowly moves the teeth and reshapes the supporting jaw bone. Clear Aligners are designed to make small movements at a time, by putting gentle pressure on your teeth. That pressure is transferred through your roots to your jaws.

The process is quite simple: First, the doctor records the shape from the patient’s teeth by using impressions or scans. The doctor prescribes the way the teeth should be straightened and submits the case to WhiteSmile Clear Dental Cloud.

Based on the doctor’s instruction, Whitesmile Clear produces a digital model of teeth progressing from crooked to straight. These models are printed with a 3D printer and utilized to produce clear plastic material known as aligners. The patient snaps the aligners onto their teeth and wears all of the daytime and night. Consuming them out merely to eat, drink and brush their teeth.


The aligners are very clear, most of the people don’t even notice them. Each and every single aligner is applicable light pressure to a particular tooth, pushing them closer to the specified position. Let’s take a good look at how this functions. Each tooth is surrounded by a periodontal ligament. This ligament is surrounded by fluid and tiny fibers that link up the teeth to the surrounding bone fragments.

Once the aligner is put on, the teeth will experience orthodontic force. This force will induce compression of teeth ligament on one side and tension on the other side. Thus, bone resorption will occur on the compression side while bone apposition will occur on the tension side. The biological cascade of resorption and apposition of bone around the roots will allow teeth movement by mechanical force.

The pressure from your aligner squeezes the blood vessels on a single part of the ligament and dilates them on the other. After 8 hours of sustained pressure, the compressed ligament responds to this stress by producing enzymes and chemical messengers. After one of the pressure, those chemicals begin to stimulate the production of bone cells called Osteoclasts and OsteoblastsOsteoclasts break down the bone near the compressed ligament.

Meanwhile, Osteoblast constructs new bone fragments on the opposite side of the teeth preventing them from being too loose. If the pressure from the aligner is disrupted for virtually any considerable period of time, the procedure needs to start over completely from the beginning. That is why it is important to put on aligners at least 22 hours every day, Specially the first few days of the new stage. If the bone fragments do not get reshape, the teeth won’t continue to be straight.

Once the bone fragments throughout the teeth finish rebuilding, it is time to take out the existing aligners and proceed to the next set. This level of rebuilding may differ considerably between individuals — it often takes longer for adults than it does for kids and adolescents. Every single aligner moves the teeth a bit further until the patient reaches the final stage, as well as the treatment method, are completed.
