Hello @Joew111 the next fields are the best on the market to my knowledge
The Shark Teeth Clinic
Negentropic Maxilla Masterwork
Negentropic Marquardt Masterwork
I have all three. For me it seems to be a long term process. Maybe because i’m already in my 40’s. The way i understand it is that physical changes take way more time than others especially bone structures. The harder the structure the more time it takes. I hope this helps.
