Class II Growth Case
- The patient is in the early mixed dentition period
- Class II Molar relationship bilateral
- Crowding in the upper & lower anterior dental arch
- Increased overjet (9mm as from the study model & clinical assessment)
- Deep overbite
- V shape upper dental arch showing maxillary constriction at the anterior region
- Most of the milky teeth are heavily filled with dental restorations(amalgam & composite) indicating questionable prognosis
Diagnosis
- Skeletal class II due to the vertical growth pattern of the mandible & counterclockwise rotation of the maxillary plane which may not be corrected by growth
- Dental class II div. 1 associated with deep over-bite
Treatment Plan
Two steps skeletal class II treatment by using:
- In the 1st step (orthopaedic Rx) to use class II functional appliance but after relief crowding of the upper & lower incisors in association with levelling & alignment by using 2×4 fixed orthodontic Appliance first which can be started at the early mixed dentition
- In the 2nd step at the permanent dentition period to use fixed comprehensive orthodontic appliance therapy
