dentist here! patient presented with proclination of u/l anteriors with open bite. congenitally missing 1 lower incisor. in spite of that , i felt i cannot reduce the bite and correct proclination without all 4s extraction. started treatment with all 4s extraction. mid treatment, I am afraid i would have more space than required in the lower arch. I feel guilty and devastated. I would like any input on how to correct this, or will the space be closed. will mild mesialisation of 2nd premolar and molar work in this case? any imput would be helpful
