Since Invisalign uses a series of clear plastic aligners in order to straighten teeth, many patients wonder what exactly makes these aligners work. The answer is a combination of computer technology and physiological forces.
With Invisalign, your treatment is planned out completely in advance. The dentist will take X-rays, photos, and impressions of your teeth that he or she will then send to the Invisalign laboratory. Using this detailed imaging, the lab will create a 3-D model of your teeth. Using this model, the dentist will plan each step of your treatment. Each set of aligners represents one step of your treatment. Aligners are worn for two weeks at a time before being replaced with a new set.
Traditional metal braces also use physiological forces to move teeth. The difference is that the wires of the braces pull your teeth, while Invisalign aligners push your teeth. When the wires of the braces are made to fit your teeth, their natural impulse is to try and straighten back out. As the wires are trying to do this, they pull the teeth with them. When the aligners are being worn, they actually push your teeth into position due to the resiliency of the plastic design. Each set of aligners represents a subtle push of the teeth to be sure, but when all the pushes get added up, it results in the completion of the treatment.
