I have a bimax protrusion and want it gone, what should I do? Have braces, should I extract teeth or opt instead for IPR?

Originally went to get braces to correct an overbite. My teeth looks better but my side profile bothers me. My lips protrude and my profile is very full and convex in naturd. I'm mid treatment & my orthodontist told me I have a bimax protrusion and that I need teeth pulled (most likely bicuspids) to fix it. Should I extract teeth or opt instead for IPR?
