Figure 1: Facial profile silhouettes with varying manipulated anteroposterior skeletal relationships. (1) M6 and F5 representing the straight profile with no manipulations, (2) M3 and F2 representing the profile with a retruded maxilla, in which the sole change made was the posterior positioning of the maxilla, (3) M5 and F1 representing mandibular retrognathism through posterior positioning of the mandible, (4) M1 and F4 representing mandibular prognathism; with the anterior advancement of the mandible, (5) M2 and F6 representing protrusive maxilla with anterior advancement of the maxilla, (6) M7 and F3 representing the bimaxillary protrusion, in which both the upper and lower alveolar segments were advanced with slight lips protrusion, (7) M4 and F7 representing the bimaxillary retrusion in which both alveolar segments were posteriorly positioned to mimic a flatter profile
