Treatment objectives and treatment plan
The primary treatment objectives were to achieve class I canines and
molar bilaterally and reduce the overjet and overbite. Additional
objectives were to relief the crowding in both arches, correct the upper
arch form, restore a pleasant smile with optimal lip line and smile arc,
achieve lip competency and enhance the patient’s profile. It was
desirable to reduce the overjet and correct the class II relation by
distalising the upper molars and retracting the upper incisors. Since
the patient presented with a deep bite, measures to prevent bite
deepening were undertaken. The patient had high aesthetic demands and
asked for more esthetic alternatives to fixed appliance therapy. A
treatment approach with Clear Aligner Therapy was the appliance of
choice using Invisalign aligners (Align Technology Inc, Santa Clara‚
CA‚USA). All procedures have been performed in accordance with the
ethical standards laid down in an appropriate version of the Declaration
of Helsinki.
