The Invisalign method is simpler than its predecessors, requiring only one set of impressions and photographs of the teeth, taken during an initial consultation.
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.
Smile shapers 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. Smile shapers 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.
