MESSAGE BOARD 2 Definitely an Ext Case-But 4s or 5s? An extraction is the agreed-upon play, but Townies must decide which direction to go teenyortho Post: 1 of 14 Hi, all! Wanted to see what extraction patterns everyone is thinking of for this case: all 4s, all 5s, or even upper bis and those blocked-out lower laterals? n 5/18/2021 emac Post: 4 of 14 5/18/2021 Same here. Here is a patient I treated many years ago with U4s and L2s extracted. I just have these photos from a before/after book I made to show patients. Should work fine for you! n tracy47 Post: 5 of 14 5/18/2021 Your case looks great! My concern with L2s is that the current incisor inclination is retroclined. Also concerned about overretraction of upper incisors. n Fenrisúlfr Post: 6 of 14 5/18/2021 All 4s, invert the slots of the U2s and L1s (if the lowers have -VE torque). That can help split the difference and position the roots accurately. n Brbraces U4s/L2s for me. n Yeah, same here. Keep it simple. Less dental movedhmjdds I agree with Brbraces. This! n Post: 3 of 14 5/18/2021 ment equals less chance of getting a relapse. I would maintain the existing " retroclined " lower IMPA as well. If she happens to lose her lower retainers and not wear it for a few days (while waiting for the new one to be made), her lower anterior teeth will still look OK. n Post: 2 of 14 5/18/2021 ucla98 Post: 8 of 14 5/19/2021 NOVEMBER 2023 | 26 | ORTHOTOWN.COMhttp://www.ORTHOTOWN.COM
