Abstract
A case report on the orthodontic management of a
10-year-old female patient with Angle’s Class II Division
I malocclusion, 12 mm overjet, incompetent lips,
a deep bite and a lower midline shift to the right using
the Twin Block of Clark is presented. Treatment objectives
included reduction of the overjet and overbite,
obtaining a Class I molar and canine relationship, and
improving the patient’s profile. After a thorough patient
assessment, a two-phase orthodontic treatment
plan was chosen with myofunctional therapy using the
Twin Block constituting the first phase of treatment.
Second phase of treatment was to be carried out using
a preadjusted edgewise appliance system. Active treatment
with the Twin Block lasted for nine months. Patient’s
compliance with the appliance was good, and
an overjet reduction to 4.5 mm was achieved with an
improvement in facial profile after the first phase of
treatment. The Twin Block of Clark is a very good treatment
alternative in managing selected cases of Angle’s
Class II Division I malocclusion.
