How EASY BRACES  acts as a habit breaking appliance ?

The oral screen like structure enveloping the teeth buccally / labially help in treating the mouth
breathing or thumb sucking habits.  This allows for the child to shift from oral to nasal breating,
which in turn allows the nasal passages to develop and the plate to descend.  The maxillary arch
therefore tends to develop into a shallow arch and a U shaped arch develops due to the parabolic
natural like shape of the appliance.  Promotion of development of a U shaped arch allows an
increase in the inter-canine dimensions of the mandible, thereby allowing resolution of mandibular
anterior crowding.
Small projections on the labial aspect of the oral screen like structure in the region relating to the
mandibular anteriors (labial grip), behaves as a lip bumber or mentalis stretcher, which in turn
deactivate an over active mentalis muscle, thereby allowing a mandibular anterior flat arch to
develop into a rounded one and thereby increasing arch perimeter.  It also allows the perioral
group of muscles to become normotonic thereby ensuring a lip seal.  A tongue spikes has also
been incorporated in the maxillary palatal aspect, which is used to train aberrant tongue habits
such as retained infantile or tongue thrust cases.  Thus, the imbalance of forces acting on the
developing arches if any from the lingual aspect are also taken care of.  The tooth channels for
upper and lower teeth are designed in such a way so as to behave like an activator guiding the
teeth into the occlusion.
