Case Report

Treatment Results
The patient's chief complaint was addressed
and all treatment objectives were met, both
functionally and esthetically. The patient and
his family are extremely satisfied with the results
of his orthodontic treatment and with not having to pursue orthognathic surgery to close his
open bite.
Dr. Stephen Yoon
Dr. Yoon attended UCSF
for orthodontic residency
and is a Diplomate of the
American Board of Orthodontics.
He currently practices in the
San Francisco Bay area.

Skeletally, his mandible grew down and forward,
and slightly autorotated counterclockwise. Dentally, Class I molar and canine relationships with
ideal anterior coupling, overjet, and overbite were
achieved. Because severe open bite was partly a
dental problem due to his accentuated curve of
Spee in the maxillary arch and the severe proclination of his maxillary and mandibular incisors,
sufficient positive overbite was achieved without
orthognathic surgery. Extractions resulted in
great improvement in incisor display and interincisal angle.
Extraorally, the patient's profile improved greatly,
and lip incompetence and mentalis strain were
eliminated. The patient now reports he is able to
bite and clench harder than before the treatment. His open mouth posture habit was also
eliminated.

Editor's Notes
The keys to the success of this nicely treated case
include a consideration of the patient's growth
potential as well as taking advantage of counterclockwise rotation of the mandible with proper
vertical control. Good patient compliance also
played an important role in a successful treatment progress. This case illustrates the benefits
of having taken a conservative treatment
approach, even when orthognathic surgery
appeared to be the only way to achieve an ideal
outcome.
