Human face is the most sophisticated complex parts of the whole body. Three dimensional approaches should be emphasized to evaluate the face in vertical, transverse, and sagittal planes. The three keystones for facial beauty are 1. correlated facial and dental midlines. 2. pupil-leveled occlusal plane. 3. concerted zygomatic arch.
Orthognathic movement should accomplish the best facial esthetics by moving maxillomandibular complex in three dimensions. How to incorporate these three dimensional orthognathic movements into the reconstruction of orofacial function, facial and dental esthetics and dental occlusion will be illustrated.
