Principles
of a Perfect Smile!
|
1.
Proportion of Centrals.
The width divided by the length of your upper two front teeth
should be between 75% and 80% or ideally 77%.
|
2.
Golden Proportion of Upper Anterior Six Teeth.
On a two dimensional picture these teeth should have specific
ratios when comparing the lateral upper teeth. |
3. Midline and Arch Alignment.Your
two front teeth should be in the middle of your face. The arch
alignment should be perpendicular to the midline or parrallel
to your eyes providing your eyes are balanced.
|
4.
Axial Inclination.
All your teeth should be slightly mesially inclined.
|
5.
Incisal Edge Line vs. Lower Lip Line.
If your lower lip has a pattern 1 character, then the upper teeth
should follow along the upper lip.
|
6.
Contact Points.
These get progressively closer to the gingiva as the teeth go
posteriorly.
|
7.
Arch Form.
If one was to draw a line through the centre of the cuspids, the
line should bisect the incisive papilla. If this line is posterior
to the papilla the arch form will be too narrow. If this line
is anterior to the papilla the arch form will appear too flat
in appearance.
|
8.
Gradation.
The teeth should appear to get shorter as one looks posteriorly.
|
9.
Gingival Symmetry.
The gums on one side of your mouth should look exactly like the
other side. When someone is smiling we should see no more than
3 mm of gum tissue.
|
10.
Gingival Contour. When
a line is drawn from the gingiva of the cuspid to the gingiva
of the central, the gingiva of the lateral should be 1 - 2 mm
lower than this line.
|
11.
Gingival Zenith.
The highest point of the gingiva should be just distal to the
long axis of the cuspid and central teeth but should be right
on the long axis with the lateral tooth. |
