Movement of Teeth in Invisalign Teeth Straightening Treatment

Several millions of people all over the world have successfully undergone invisalign treatment to make their smile more beautiful. Yet a large number of prospective patients have not been able shake off their doubts about the cutting-edge teeth straightening technology. Conventional metal braces have been around for ages. Therefore, people already know a lot about it. Whereas invisalign is a pretty recent invention and so it is obvious that people are curious to know more about it.

The cutting-edge align technology

The invisalign technology performs its work in a way that is not only easy to understand but also interesting. In this context it is important to touch up with its history in brief. 

Invisalign is owned by Align Technology. Back in 1997 the founders of the organisation had gathered in California with the aim of sharing knowledge to facilitate invention of a technology that not only straightens but also repositions teeth effectively.

A couple of years later, invisalign clear aligners first came into the market. Thus, the year 1999 stands as a landmark in the history of modern orthodontic teeth straightening. Since then, several millions of people from all over the globe have been benefitted from this technology with straightened teeth and more beautiful smile. In a rough estimate out of those several millions, near about 2 million have been teenagers.

Process of orthodontic teeth movement

People fondly call the aligners that are used in invisalign invisible braces. It is perfectly right to call by that name. As the name suggests the aligners practically remain invisible inside the mouth while improving your smile. Conventional braces are made of shiny metal and they stick out prominently from the mouth. In contrast to that the modern technology offers clear transparent aligners, made of high-quality flexible plastic that, are nearly invisible inside the mouth.

Clear transparent aligners move the teeth similar to the way conventional braces do. Thus, it is also justified to call these aligners as invisalign braces. Both the modern and conventional orthodontic teeth straightening procedures have a common goal. They gradually and comfortably move the teeth into proper or desired positions. This shifting or reposition is never achieved overnight but over a period of time.   But there is a subtle advantage to speed up the treatment process for invisalign users. They can keep wearing the braces for 22 hours a day and that speeds up teeth movement. Unfortunately, patients using conventional braces have no such advantage to facilitate faster teeth movement.

The inherent mechanism

Let us resort to little physiology to understand the exact mechanism that facilitates repositioning of the teeth. The teeth remain connected to the jawbone through a periodontal ligament. The ligament is formed of a collection of fibres that contain a type of protein called collagen. The fibres in the ligament technically hold the teeth to the bone underneath.

The collagen fibres remain connected to a tooth root while the fibres on the other side of the periodontal ligament get attached to jawbone. The fibre in the ligament makes a sling around the teeth as well as holds those in place. As a result, the teeth are capable of limited movement to respond the force associated with biting.

The technology is ever improving

Our teeth have a dynamic nature. They keep changing because of the impacts of periodontal ligament, jawbone and cementum. When you bite down, the act resonate tension as well as compression. The resonance is relayed to the periodontal ligament through the protein fibres. Tension stimulates cementum deposition in the bones while compression leads to dissolution of the bone and the cement. These contrasting things keep happening to help the teeth maintain balance as well as to hold them in their respective positions.

Thus, every time you look in the mirror you may see your same smile. But the fact is it is constantly getting changed although you may not be able to register that.

Repositioning teeth through natural processes

Invisalign technology utilises the natural processes or phenomena that keep occurring in the mouth. The clear transparent aligners gently manipulate the forces of compression and tension to reposition the teeth. The process continues smoothly over a period of time. Before the transparent plastic aligners facilitate teeth movement, processes of cementum and resorption of the bone take place. Even deposition of new bone takes place.

Throughout the duration of your teeth straightening treatment with invisible braces you change to a new set of aligners every couple of weeks. Each new set facilitates about 0.25 mm of repositioning of the teeth in the first 72 hours or three days. To be precise only the periodontal ligament will move that much and not the supporting bones.

In order to have a lasting effect of the repositioning of the teeth the supporting bones also have to move. These bones are the ones that will hold the teeth in their shifted positions. It may take up to a couple of weeks for the ligament fibres to supply sufficient quantity of cementum to hold the bones in their new position. In Invisalign teeth straightening treatment patients typically have to use a set of aligner for two weeks.

Shifting the teeth to new position is relatively easy, but maintaining that position is rather difficult. This is where the necessity of wearing the aligners for sufficient length of time each day proves important. If you neglect wearing the braces for the suggested length of time your teeth are more likely to relapse or move back to the initial position. This situation is absolutely unwanted as that extends the time of your treatment. 

How can you avoid a relapse? Skilled and knowledgeable orthodontists providing Invisalign treatment at Chatfield Braces emphasise, there is just no better alternative to wearing the invisible transparent aligners 20 to 22 hours a day. Not only this ensures the treatment is effective and on right track but also each set of aligners is doing its expected job to the optimum level.
