The Invisalign method is simpler than its predecessors, requiring only one set of impressions and photographs of the teeth, taken during an initial consultation.
These impressions are used to create a three-dimensional computer projection of how the teeth could be moved incrementally, forming the basis for developing a series of custom-made aligners designed to accomplish this movement.
Invisalign aligners are manufactured at the Align Technologies dental laboratory using computer-aided design/computer-aided manufacturing (CAD/CAM) processes. The aligners are sent to the dentist, who typically dispenses them in groups of one or two at a time during regular check-up appointments (about every four to six weeks) so that treatment can be properly managed. Each aligner must be worn in its specific order for about two weeks, during which time it moves the teeth in small increments of about .25 millimeters to .33 millimeters. Although the aligners are removable (for eating, drinking certain beverages and brushing/flossing), they must be worn at least 20 hours a day in order to reposition the teeth successfully.
A typical Invisalign treatment requires 20 to 30 aligners for both the upper and lower teeth. Most adults complete their treatment in less than one year. However, treatment time depends on the specific alignment problem.
Invisalign is currently approved for adults and teenagers with completely erupted permanent teeth who can faithfully follow the directions for treatment – how long they have to wear the aligners each day, what they can and cannot eat and drink, seeing their dentist for follow-up appointments, etc. For example, dentists recommend that you drink only water while wearing Invisalign trays, to prevent staining of the plastic. If you do not follow treatment recommendations, you may compromise treatment success.
Simpli5 clear braces are a fast and simple orthodontic aligner system intended for minor correction of the front teeth and can be used to straighten both the lower and upper sets of teeth. Simpli5 does not rely on traditional brackets and wires, and is therefore suitable for correcting minor cases of misalignment and spacing problems. It is also perfect if you would like a clear brace treatment but does not require the intensity of Invisalign invisible braces.
However, for more than a little straightening, there may be other orthodontic treatments more suitable.
