Is Invisalign applicable in this case? I wore braces before only on upper jaw (two premolars extracted - you can see the gaps on pictures) but now the case is that lower teeth need correction in order to be able to reduce overjet... I was wondering if Invisalign can make the correction or I need to start braces therapy again... The reason I ask is the fact that many of the use cases that I see online are 'minor' comparing to my case...
