Well-defined angles, vertical and hori- zontal lines around the forehead and mouth, and sunken eyes. The subjects’ faces were cat- egorized into four main types by their facial characteristics and the first impression they make on others, as follows: The study included a computer analysis of 91 full-face smile photographs of 42 male and 49 female subjects aged between 18 and 30 years. ![]() For the purposes of this study, four main facial types were defined. By mathematical modeling, statistical models are generated by which we determine the facial type de- fined by perception, impression, and beauty rather than by facial symmetry or anthropol- ogy. This study analyzes the facial characteristics that play an essential role in making the first impression on others. Such an analysis then enables the creation of a digi- tal design for the prosthetic restoration of the anterior teeth. The aim of this study was to create math- ematical modeling to generate statistical models that reliably and quickly identify a person’s facial type while smiling. The relationship between how people define themselves, the first impression they make on others, and their facial characteris- tics has implications for how people interact socially in the modern world.4 The expres- sion on a person’s face creates the first im- pression with others and has a high social value.5,6 ![]()
