Smile Design
|
|
|
1. Horizontal
Symmetry: Draw an imaginary
horizontal line through the centre of
both your pupils and another horizontal
line between the tips of your canine
teeth. Ideally, these two horizontal
lines should be parallel. Often, one
side slopes down. |
|
|
|
2. Vertical Symmetry:
Draw an imaginary vertical
line through the centre of your face.
This mid-line should run through the
centre of your eyes, nose and chin.
Ideally, the mid-line should also run
through your two central incisors thus
making the central incisors a mirror
image of each other. |
|
|
3. Smile Width:
Ideally, a wide smile will show your
first molar to first molar tooth. Although
if you have a narrow smile you may only
see the front six teeth from canine
to canine. |
|
|
4. Smile Line:
Draw an imaginary curve along the bottom
of your upper teeth and compare it to
an imaginary curve of your lower lip.
Ideally, your smile should be curved
in order to look younger. |
|
|
5. Gum Line:
Draw an imaginary curve along the top
of your upper teeth. Ideally, only the
pink triangular parts of gum between
the teeth show. However, some people
show a lot more gum or the gum that
shows is uneven giving an irregular
gum line. |
|
|
6. The Golden
Proportion: This special proportion
was discovered by the Greeks and is
found in many areas of nature. Ideally,
the widths of each of the front teeth
compared to the next follows this special
proportion. |
|
|
7. Tooth Proportion:
Ideally the width of a tooth
should be approximately 80% of the length.
However for patients that wear/grind
their teeth, this ration is closer to
1:1 as the teeth have shortened and
become squarer. This is a way to measure
exactly how much tooth has been lost
over the years and is often used to
rebuild edges of teeth to their ideal
proportions and perfect smile. |
|
|
8. Embrasure
Space: These are the little
triangular like spaces between the tips
of the front teeth. Without embrasure
spaces, the teeth would look like flat
piano keys with no character to them.
Ideally, the embrasure spaces should
be smallest between the two central
incisors and gradually become larger
as you examine teeth further into the
mouth. An ideal feminine smile tends
to have more definite round embrasures. |
