Practice to acquire greater familiarity and skill will prove useful to the smile designer. In addition to the qualitative factors, the correct orientation of the patient’s face is absolutely es- sential. Some software on Mac operating systems allows rotation of the image with a simple move- ment of the fingers. In general, however, it is possi- ble to trace a bi-pupillary plane that the software will recognise as the horizontal plane to which to make reference for adapting the image. Another efficient method, with a dual function, is that of using the cropping grid. This offers the possibilityofcroppingthephotographtocentrethe image for use in ADSD. It permits us to align the bi- pupillary plane horizontally to check the symmetry in relation to the sagittal plane. There is another simple but efficient way: in- creasing the zoom on the photograph. The pupils will be more detailed and thus, by rotating the photograph,itwillbepossibletotakeasareference point the upper edge of the software window, onwhichtoverifythepupillaryalignment.Lateron, it will be possible by scrolling the image towards the top to examine the mouth and the teeth to verify the occlusal plane. _Mapping of the macro-aesthetics (face): having decided on the correct position of the face for a detailed aesthetic analysis and after a digital analysis, it is indispensable to mark the face and the smile with reference lines and areas, verifying symmetries and asymmetries (Fig. 18b). The first thing to do is to mark the reference points and morphological determinants (face marker); these should be saved in the project from the photo- graph because they are fixed anatomic topo- graphical points in both the extra-oral and intra- oral soft tissue, obviously bordering on the teeth and gingivae. From now on, it is essential to save thevariousADSDprojects.Inthismanner,weshall have immediately at our disposal the cardinal points of the topographic anatomy on which we shalllaterbasetheproportionsofthefaceinterms Fig. 18b_Mapping of the macro-aesthetics of the face.
