Contra-Indications
for the
Pre-Orthodontic Trainer
The
Reluctant Child/Parent
The TRAINER¨ is suitable
for most malocclusions but will not be of benefit if the child decides
not to use it on a daily basis. The child and parent must be motivated
to get a result, otherwise result will be minimal. Conversely, the motivated
child will produce amazing results.
Severe
Class III
Skeletal Class III
has a hereditary factor and mostly the child will not be able to wear
the TRAINER¨ . Restrict cases to mild or pseudo - Class II malocclusion.
Posterior
Cross Bite
The TRAINER¨ does
not have sufficient passive expansion capabilities to correct a posterior
crossbite. However, many of these cases are caused by oral habits and
will not be stable unless these habits (tongue, sucking and breathing)
are corrected. First correct the crossbite with transverse expansion,
then apply the TRAINER¨ program to correct the myofunctional habit and
the mandibular alignment (rotation).
Using the TRAINER¨
with removable (functional) appliances, such as this, can assist speed
and stability of treatment.
Complete
Nasal Obstruction
Always check a child
for a patent airway. The child should be able to breathe through the nose.
ie. a patent airway must be present. If there is complete or semi complete
nasal obstruction refer to otolaryngologist (ENT) for assessment.
Rule of Thumb:
Test child in chair with TRAINER¨ in place and lip over hole. If they
can keep it in place with lips together for 5 minutes or more - they are
not obstructed. Suggest ENT consultation, then the TRAINER¨ program -
if complete obstruction.
Do not try to fit
the TRAINER¨ into the child's mouth. Allow them to place it themselves.
