Conventional gingival beveled attachments were placed on the labial and
lingual surfaces of the dentiton (upper labial attachments: #14, #12,
#11, #21, #22, #23, #24; upper palatal attachments: #13, #12,
#11, #21, #22; lower labial attachments: #34, #33, #32, #31,
#41, #42, #43). (Fig. 3) Forty-eight upper and lower aligners were
used to close the open bite, de-rotate and alleviate the crowding on the
lower anterior teeth.
