Bemerkungen
- After 27 aligners in both arches, the patient was Class I canine on the right side and 3 mm Class II
canine on the left. - Aligner wear compliance was good and oral hygiene was
excellent. - The majority of the crowding in both arches was resolved during
the mandibular advancement phase. - The bilateral posterior open bite present
would be closed by additional leveling of the curve of Spee, along with lingual
root torque of the upper anterior teeth. - By reducing the anterior interference's,
the mandible would be able to auto rotate into a better Class I relationship. - Additional Aligners Phase: One set of Additional Aligners was used, which
lasted 9 months (19 U/L stages, weekly aligner changes.) - Reverse curve of Spee was added to the set-up of the lower arch to correct the deep bite
and remove any heavy anterior occlusion, in order to close the posterior
open bite. - A 4 oz. Class II elastic was worn on the left side only for just
6 weeks, from aligner stages 14 to 19 (with Precision Cuts on the upper canine
and the lower first molar), to complete the sagittal correction to Class I. - All remaining rotations were fully resolved during Additional Aligners. The
total treatment time for this patient was 21 months (11 months for the
mandibular-advancement phase, 1 month for transitional aligners awaiting
Additional Aligners, and 9 months for Additional Aligners with standard
Invisalign treatment), which is well within the expected treatment time for
this severity of Class II malocclusion.
