Treated at Yonsei Baro

DiagnosisCrowding in both arches. The upper right central incisor was flared forward and rotated, and the tooth beside it sat behind the arch. Lower incisors were crowded with the canines pushed outward. Upper and lower midlines did not match.

Treatment planSpace created without extractions, then upper and lower front teeth aligned with Invisalign and the midlines coordinated.

DiagnosisGrowing patient with crowding in both arches. The upper right canine and both lower canines erupted outside the arch. The upper front teeth covered the lower front teeth deeply (deep bite). No skeletal problem.

Treatment planFixed braces to bring the canines into the arch and correct the deep bite.

DiagnosisNot enough space in the upper arch, so both canines erupted high and outside the arch. The upper front teeth fully covered the lower front teeth (severe deep bite).

Treatment planSpace created without extractions to bring both canines into the arch, with the deep bite corrected using braces.
