Bemerkungen

In order to prevent the dislocation of the braces, I gave up the initial invisalign treatment after the extraction of the four first premolars。Without wearing any orthopedic device, it taked advantage of the growth advantage of teenagers to automatically align teeth.Half a year later we started a refinement to continue to align teeth and close the tooth extraction gap.
