Chief complaint: Crowding in the upper and lower jaw
Diagnosis
– Skeletal tendency to Class II
– Class II edentulous and molar ratio bilaterally
– Weak crowding in the maxilla (4 mm)
– Weak to slight crowding in the mandible (3 mm)
– Displacement of the lower midline: 5 mm
– Moderate deep bite: 4-5 mm
– Retroclined upper front teeth

Treatment goal
Alignment of the upper and lower teeth
Achievement of a Class I relationship of the molars and canines
Correction of the midline shift
Correction of the deep bite and proclination of the upper front teeth
Stabilization of overjet and overbite

Results and aftercare
Crowding resolved, minor deviation from Class I ratio of molars and canines. Overjet and overbite
stabilized.
Crowding resolved, minor deviation from Class I ratio of molars and canines. Overjet and overbite
stabilized.
Correction of the midline shift by 4 mm. Resolution of crowding with the help of ASR. Further
adjustment of overjet and overbite.
