Class II with moderate deep bite and crowding
Age: 25 years Gender: female Chief complaint: Crowding in the upper and lower jaw
Skeletal tendency to class II
Class II ecteeth and molar ratio bilaterally
Weak crowding in the upper jaw (4 mm)
Weak to minor crowding in the mandible (3 mm)
Displacement of the lower midline:
Moderate deep bite: 4-5 mm
Retroclined upper front teeth
Number of aligners:
Top: 20 aligners (2 phases) and 2 refinements (1 phase).
Bottom: 20 aligners (2 phases) and 2 refinements (1 phase)
Total treatment time:
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.
Correction of the midline shift by 4 mm. Resolution of crowding with the help of ASR. Further adjustment of overjet and overbite.
