As with other technological advancements in cosmetics, the ways to achieve a perfect smile have also become easier. When Invisalign® was introduced in 1999, orthodontists were skeptical about this technology. Almost 20 years later, the most advanced clear aligner system in the world has improved over 5 million smiles all over the world.
But have you ever wondered how these seemingly innocuous plastic molds of your teeth make your pearly whites fall in line?
The Science Behind Invisalign
The technology behind braces is pretty straightforward. You get a metal bracket around your teeth that will push them into proper position. The technology of Invisalign® is almost the same. According to Williams Orthodontics who provides Invisalign® in Canton, each custom-made aligner shifts your teeth slightly by using the right amount of force in the right place at the right time.
It’s more than that, though. The entire Invisalign® treatment starts with your orthodontist taking dental impressions of your teeth. Invisalign® technicians make a 3D model of your current teeth. From there, they create a step-by-step model on how to move your teeth. This will be their basis for creating each of your aligners.
Unlike braces, which you wear constantly, you’ll only wear each aligner for two weeks. With braces, you will be visiting your orthodontist every six weeks to have your braces tightened. With Invisalign®, each subsequent custom aligner has been designed to be tighter than the last one, creating the same result as braces. Each aligner puts pressure on your teeth so that at the end of two weeks, the teeth will have moved in a way that matches the straighter aligner. You do this until you reach the final set of aligners—the models of your perfectly straight teeth.
Achieving the perfect smile takes a lot of work but with the science behind Invisalign®, straightening the teeth has never been easier.
