Classification Case report
  • ABSTRACT
  • TITLE
 This case report was a 12-year-old boy with Class II division 1 malocclusion combined with mandibular retrusion associated with proclined upper and lower anterior teeth, deep overbite, and excessive overjet. The treatment object is upper arch retraction and guide mandible forward.
   Usually, class II malocclusion is one of the most commonly seen problems in daily orthodontic practice. And, the most common characteristic of Class II malocclusion is the mandibular retrusion.
Instead of complicated removable functional appliance, we delivered a clear anterior bite plate for bite opening to free the mandible
Additionally, muscle training, include bite force training and mandible forward muscle training, we requested patient to do it everyday . And then, class II elastic for upper anterior teeth retraction and mandible forward was applied.
After 27 months of orthodontic treatment, by overall superimpose, the correction of large overjet was achieved by retraction of upper anterior teeth and flaring of lower anterior teeth and mandible growth. The convex profile was improved and became more harmony.
