what is this called?
arch form
what is this called?
tooth alignment
what is this called?
Bilateral cross-bite
what is this called?
intercuspal position
what is this called?
molar relationships
what is this called?
incisor relationships
what are stagnation areas?
places where plaque bacteria can accumulate that is hard to clean
contact points between teeth are important for? 2
food displacement during mastication
arch alignment/stability
what is a marginal ridge?
elevated enamel that forms the mesial and distal borders of the occlusal surface of the teeth
each upper tooth contacts with what? 2
its lower antagonist
its distal neighbour
tooth alignment is determined by? 2
path of eruption
forces exerted on the teeth
what is the neutral zone (tooth alignment)?
the neutral zone is clinically important for what?
denture construction
the upper molar occlusal surfaces face?
buccally
the lower molar occlusal surfaces face?
lingually
what is this line called?
Curve of Wilson
which arch is slightly longer?

upper arch
the upper buccal cusps are ? to the lower buccal cusps
buccal
what is this called?
unilateral cross-bite
what is this line called?
