Selecting & Setting Teeth - 40
cervical necks lie at or above this line. If shorter teeth are selected, the esthetic result
will be compromised.
Palatal Midline - With a pencil (NOT an indelible stick) and a straight edge, draw a
line through the middle of the incisive papilla and the mid-palatal raphe, extending it
onto the land area of the cast. Check your occlusal rim for symmetry about this
important midline. If it is not symmetrical, adjust the rim prior to sending it to the lab
for placement of teeth.
Distal aspect of the incisive papilla - In the edentulous maxilla, a line drawn
perpendicular to the palatal midline, passing trough the distal aspect of the incisive
papilla should normally intersect with the cusp tips of the canines. Draw this line
with pencil and a straight edge, on the cast, extending out to the land area. It will
provide verification that your tooth size selection was correct. Additionally, it will
provide another line to verify the symmetry of the wax rim and denture tooth setup.
On average, the facial surface of the central incisors should be approximately 8-10
mm anterior to this line.
