K Clear Case
Class II moderate deep bite with crowding
Age : 25 years old
Gender : Female
Chief complain : crowding in upper and lower teeth
Class II skeletal tendency, class II canine and molar relation bilateral. Mild crowding in upper jaw (4 mm), slight to mild crowding in lower (3 mm).
Lower midline shift: 5 mm
Moderate Deepbite: 4-5 mm
Retroclined upper front teeth
Number of aligners:
Upper: 20 aligners (2 phases) and 2 refinement (1 phase refinement)
Lower: 20 aligners (2 phases) and 2 refinement (1 phase refinement)
Align upper and lower teeth, achieve class I molar and canine relationship. Midline shift correction. Deepbite correction and proclining the upper front teeth, achieving a stable Overjet and overbite.
Advanced attachments have been used to level the curve of Spee and extrude the molars slightly. Class II elastics were used with more forces on the left side.
Resolved the crowding, slightly deviated class I canine and molar relationship, stable overjet and overbite. Midline shift correction by 4 mm.
Decrowding with the aid of IPR.
Adjusting the Overjet and overbite.
Double retention was used at end of treatment.
