[Line of cutting edges of the upper teeth and its conformity with the contours of nose and lower lip while smiling].
Observations were carried out--visual and via photos--of 180 subjects (83 males and 97 females) in order to establish the incidence of coincidence between the line of the cutting edges of the upper front teeth with the contours of the base of the nose and the lower lip while smiling. It has been established that the total configuration of the cutting edges is perceived visually as a curved wave-like line, whose arch, in the majority of the cases, does not correspond to the form of the nose but, most often, coincides with the contuour of the lower lip. Attaining of the mentioned harmonious conformity between those two linesis recommended in the working out of aesthetic prosthetic constructions.
