For the objective aesthetic analysis, the focal length is modified, starting from the first photograph (Fig. 6). For this parameter, the following classifi- cation criteria could be applied: _macro-aesthetics (extra-oral analysis of the face); _mini-aesthetics (extra-oral analysis of the mouth); and _micro-aesthetics (intra-oral analysis of teeth and gingiva). As regards the aesthetic analysis of the smile, the specific areas of the objective analysis that are pertinent to dentistry are as follows, based on that provided by a number of many authors: _Facial analysis: Frontal/lateral, determining mor- phological features, horizontal/vertical reference lines, vertical/horizontal facial proportions, golden ratio,horizontal/verticaldimensions,analysisofthe facial profile, and analysis of the lips, nose and eyes as regards position and size (Fig. 7). _Dental analysis: Dental composition, dental ar- rangement and position, dimensions, proportions, shapes, contours, margins, textures, surfaces, axial inclinations, inter-incisal angles, interproximal contacts and colour (Fig. 8). _Dento-labial analysis: Labial dynamics, smile line, widthofsmile,labialcorridors,occlusalplane,mid- line,andinter-incisalandcommissurallines(Fig.9). _Phonetic analysis: This is complementary to the dento-labial analysis and involves the recording Figs. 13a–f_Virtual modelling of dental forms with DDID.
