Invisalign/Class 3 Bite- do I need elastics? Will my bite get worse if my teeth start moving? (photos)

Hi! I am doing Invisalign after 4 consultations, I found the Dr. on the Invisalign site. I was told I have class3/end to end bite and moderate crowding and can be fixed with IPR on molars/bottom teeth. I was told by first consult that I would need to wear bands, however the Dr. I am moving forward with said no bands needed as it can cause TMJ issues. My question is- can my issue be fixed with Invisalign/IPR/and no bands? I don’t want jaw issues or a worser bite!! Help!
