[Case of bimaxillary protrusion and lip evaluation on cephalogram].
One of the goals of orthodontic treatment is to obtain the best balance and harmony of facial lines, especially it is important to retract the lip in bimaxillary case. A 12-year and 4-month-old boy was first seen with the chief complaint of excessive lips protrusion. We treated him by the edgewise method for 34 months, and evaluated the change of facial profile. Excessive lip protrusion was eliminated, and arch leveled. Overjet and overbite were reduced. Mandibular growth increased the prominence of the chin, and reduce the protrusion of the lower lip.
