Class II Growth
- Class II Molar & Canine Relationship Bilaterally
- O.J= 6mm , O.B = 5mm
- Deep overbite
- Increased curve of Spee
- Bilateral maxillary posterior crossbite
- Maxillary constriction, narrow palate
- Sever upper anterior crowding, mild lower anterior crowding
- 2mm shift of lower midline to the left side
Diagnosis
- Skeletal class II due to mandibular retrognathism
- Dental class II div.1
- Bilateral maxillary posterior crossbite due to maxillary constriction
- Deep over-bite associated with the increased curve of Spee
- Sever upper dental crowding, mild lower anterior dental crowding
Treatment Plan
- ENT consultation
- A maxillary bilateral expansion, RME, using hyrax expander.
- Fixed orthodontic therapy associated with class II mechanics
- Reduction of the deep bite by levelling curve of Spee using lower incisor proclination rather than extraction because they are severely retroclined
