d) Subnasale to gnathion = lower facial height
measured when mandible is at rest position.
Because of dental wear and tear, facial height is lost during aging - a process known as “bite collapse.
8220;The loss of facial height because of bite collapse is only now just beginning to be considered in a tiny number of dental practices,” says Dr.
However, as we age the teeth wear down and the jaw recedes, leading to the facial height
[the area between the nose and chin] decreasing and the lower part of the face dropping.
Snap-On Smile is the non-invasive esthetic and diagnostic treatment option for applications including smile enhancement, as a vehicle for increasing facial height
(vertical dimension) and as cosmetic partial dentures.
The lack of teeth leads to decreased facial height, protruding lips and an undeveloped alveolar bone [Gorlin et al.
However, it is very important to obtain the correct vertical dimension as it will result in a less distinct facial appearance, as the vertical facial height is nearer to normal, the lips less protruding and sulcus mentolabialis less distinct.
Statistical analysis of the cephalometric measurements in the otitis media group and the control group revealed significant differences in the angle between the anterior skull base and medial skull base, upper facial height
, and anterior facial height
Romberg's disease), excessive facial height
, lop ears, cleft lip/palate, buck tooth deformity, anopthalmos and micropthalmos, anencephaly, "frog face" (Crouzon's disease), mocrotia, and colombomata of the lower eyelids.
Applications include using the Snap-On Smile as esthetic provisionals in implant cases, a vehicle for increasing facial height
(vertical dimension), cosmetic removable partial dentures, and even as a long-term smile enhancement.
OSAS patients tended to have a posteriorly positioned and posteriorly rotated mandible with a higher gonial angle, a longer lower facial height
, a greater mandibular plane angle, and a moderately retracted chin.
Face Lift Dentistry reverses years of wear and creates the ideal facial height
that enhances the patient's facial features.
