SMILE LINE -
The shape of your teeth should follow your Smile
Pattern. For a Commissure Smile the convex curve through
the six upper anterior teeth should follow the curve
of the lower lip

|
DOMINANCE OF THE CENTRAL INCISORS
- Your two maxillary incisors (2 front teeth)
should be symmetrical and their width should be 80%
of their height with a perpendicular midline
|
 |
|
SILHOUETTES -
The curve of your maxillary incisors (2 front
teeth) should match or silhouette the curve of the laterals
(teeth beside front teeth). The laterals should silhouette
the cuspids (eye-teeth) and so on.
|

|
PROGRESSION OF MAXILLARY INCISAL
EMBRASURES - The embrasures between the maxillary
centrals (2 front teeth) should be the smallest with
the respective embrasures gradually getting larger to
the cuspid (eye-teeth). This creates the illusion of
delicate laterals.
|
 |
|
PROGRESSION OF CONTACTS
-
The contact points should follow the smile line
and silhouette the lower lip.
|
 |
|
AXIAL ALIGNMENT - The
vertical axis should be perpendicular and begin to angle
mesially (toward the centre) from midline to posterior
teeth.

|
GINGIVAL ZENITH -
When you are smiling we should see no more than
3mm of gum tissue. Also the gum crests between teeth
should follow the smile line.
