Lips, Teeth, Chin, and Smile Analysis
The basic elements of dental occlusion need to be known because of the important role played by the dental structures in supporting and shaping the lower third of the face. The sagittal, vertical, and transversal relationship of the two arches during occlusion, as well as any crowding, loss, or abnormal shape of the teeth should be noted as a matter of routine during the direct facial lower third examination.
