she demonstrated excellent adherence
to the prescribed orthodontic treatment
plan. Her HFV compliance tracker showed
she missed only one day, and she reported
that she wore her aligners consistently
all day, every day except for meals, and
then quickly replaced them. She could
literally see the changes occurring in
photos, which kept her motivated to
stay on track.

A great finish requires and deserves
a great retention strategy. All prescribed
movements had been achieved as programmed, and after completing 4 days in
her final aligner, the patient thought her
job was done. She did not wear her final
38th aligner for 5 days before returning
for her next scheduled appointment.
Orthodontic relapse can occur quickly,
and the ideal lower anterior achieved by
Aligner 19 had already begun to slightly
shift. Fortunately, the high-frequency
device was able to help comfortably
seat the final aligner and effectively
"recapture" the lower incisors.
This occurrence underscores the
importance in clear aligner therapy to
provide clear instruction for patients
to remain in their last aligner until their
next scheduled visit, even if it is beyond
the normal prescribed wear time. The
patient now uses HFV for 5 minutes daily
in retention to improve bone density3
surrounding her dentition, helping to
preserve the Class I bite and beautiful
finish she'd dreamed of for years. ■
