What's in a pretty face? In our world, unfortunately, too much. As orthodontists our goal should be to provide our patients with a stable, functional occlusion. Consider, however, the importance of changing our patients' future by significantly improving their facial esthetics. The combination of a very narrow maxillary arch, three absent upper left incisors, and a protrusive lower jaw provide a platform for dramatic improvement in our patients' facial esthetics.
