Exposure of Maxillary Incisors
In facial esthetics, the upper incisors are directly associated to the upper lip in relation to important aspects, such as the length of the upper lip, teeth size, intrusion extrusion leve and vertical development of the maxilla.
In resting position and under normal conditions, depending on the size of teeth, the maxillary incisors must be exposed some 2 mm or 3 mm in relation to the upper lip stomion.
The exposure of the incisors at the end of ortho treatment is as important as the position of structures, upper lip, lower lip and soft menton.
One of the main signs of facial aging is the falling of facial tissues , such as the upper lip covering the upper incisors reducing the exposure of upper incisors.
The opposite takes place in the lower. As the patient gets older, the mandibular incisors will bemore exposed.
Characteristics of “aging” may be delayed by means of a good orthodontic planning.
