Invisalign™
These look like small colourless gumshields, and are almost invisible. Treatment with them involves a series of thin, clear, precisely customised aligners that gradually move the teeth. Each aligner is worn for about 2 weeks, and a series of aligners are used until the teeth are straightened. The aligners are worn full-time, and taken out only for eating and brushing. They are suitable only in specific orthodontic cases.
