Comments

1.we started with a first phase of symmetrical mandibular advance , on the left the class II was greater, at this stage we programmed a leveling of the spee curve.
2. In a second phase we made left distalization and elastics to get the class I canine left.
3.The third stage was to improve the highlight and with superior IPR and achieve adequate over-ordering with pure lower incisor intrusion.
