When you take the patient photo for cosmetic evaluation and imaging be sure to have the teeth slightly apart. This makes the incisal edges much easier to see and patients will notice the chipped and misaligned teeth. Plus it is much easier to drop in a smile from the library if the lower teeth are out of the way. Another tip is to be sure the occlusal plane corresponds to the library images. That probably means the photo is taken at right angles to the occlusal plane. If the photo you take is out of alignment with the library images when you drop in the library image it looks deformed.
