In adult cases of deep bite requiring retraction of the maxillary
anterior teeth, bringing about vertical intrusion using an
aligner appliance alone is considered difficult. The present
case involved a patient with Angle Class II, division 2 malocclusion,
presenting with the chief complaints of excessive gingival
display and crowding. Temporary anchorage devices were
placed in the maxillary alveolar gingiva, and intrusion of the
maxillary anterior teeth was performed using precision cuts
and traction via elastics in the anterior region of the aligner.
This report presents the treatment results that were achieved
in a short period of time using these mechanics.
