Diagnosis and Etiology
A 13-year, 3-month-old-Asian male presented
to the University of Washington School of
Dentistry Graduate Orthodontic Clinic with
the following chief complaint: " he has some
crowding and missing a lower back tooth. "
His reported medical history was noncontributory,
and he received routine dental care at
a private pediatric practice in the suburbs of
Seattle. The mandibular right first molar was
extracted in 2017 due to internal root resorption,
and no space maintainer was placed.
Extraoral and Intraoral Findings
The patient presented with a dolichocephalic
facial pattern with a longer lower facial third.
He was relatively symmetric with equal facial
fifths. His smile arc was consonant with the
lower lip and showed 100% of his incisors
on full smile. His facial profile was convex
with an obtuse nasolabial angle and normal
nasolabial fold.
He presented with a Class II division 1 subdivision
(the left side was Class I) malocclusion.
He had an increased overjet of 5 mm, an
increased overbite of 4 mm, and a moderate
mandibular curve of Spee. His maxillary
midline was coincident with his facial midline;
however, his mandibular midline was 2 mm to
the right of the facial and maxillary midlines.
Both arches were ovoid in shape with a
moderate maxillary arch length deficiency of
4 mm. There was mild mandibular anterior
crowding (3 mm) with 2-mm spacing between
the mandibular right second premolar and
mandibular right second molar due to the
missing mandibular right first molar (Figures
1 and 2). The mandibular right second molar
was mesially inclined as it tipped in the mandibular
right first molar space.

Radiographic Findings
A panoramic radiograph at pretreatment
showed normal condyles of good cortication.
All third molars were developing. He was missing
the mandibular right first molar (due to
previous extraction) but otherwise presented
with a full completement of permanent dentition.
The mandibular right second molar was
tipped mesially into the edentulous space. A
1- × 2-mm ovoid radiopacity was present over
