Comments
- Our patient was just in CS3 vertebral maturation, so we started our case with a pre-MA phase (21 aligners) to level the curve of spee, expand, and de-rotate.
- Afterwards we did 4 MA phases, 3 of 2MM and 1 of 1.3MM, because I really prefer not to do several movements during MA.
- We are very happy because we achieved all our goals. Invisalign teen with MA is innovative treatment for growing patient and in my option the best way to treat Class II malocclusions with mandibular retrognathia. It's very comfortable and patient friendly.
