I can’t say by just looking at photos that teeth extraction were necessary or not. X-rays of previous treatment would be more helpful. See your chin is prominent, towards Class 3 profile. If your problem is more of chin prominence then you can go for genioplasty (check google). As for your question, reversal can be done with help of Dental Implants. But you will need another Orthodontics treatment to create space for teeth reversal. First they will create spaces for extracted teeth, then they will put dental implant there.
