Anterior guidance and aesthetics in prosthodontics.

Aesthetic determinants in prosthodontics are related to imprecise and often vague objective and subjective factors. Anatomic and functional studies indicate parameters of form, position, and contour of anterior teeth and the incisal guide angle. The final aesthetic composition is best determined by a continuing, ongoing evaluation designed to help the patients actively develop a perception of their own self-image and aesthetic potential. Incisal guide factors are determined independently of condylar elements. The final occlusal scheme is developed and coordinated with both the condylar and incisal guide elements.
