This patient has severe crowding on the maxillary arch. The occlusal view will show that the arch was so crowded that not all the teeth were able to fit in the natural arch of the dentition. 23 months of braces aloud the crowding to resolve and for the arch form to develop into a more natural and stable arch form. In this case from the front we can see the crowding but can also see that the midlines (where the two front teeth touch) are off from the upper and lower arches. So along with correcting the crowding the final picture also show that the midlines were aligned!
