Answer 2

right non-functional

Question 3

What border movement in the sagittal plane is the most anterior point?

Answer 3

maximum protrusion

Question 4

What border movement in the frontal plane is the most superior position?

Answer 4

maximum intercuspation

Answer 5

working movement

Question 6

When horizontal overlap changes, how does that affect vertical overlap?

Answer 6

remains unchanged

Question 7

As horizontal overlap increases, what occurs?

Answer 7

anterior guidance angle decreases

Question 8

Horizontal overlap results in less vertical displacement of the mandible. How does that affect posterior cusps?

Answer 8

flatter posterior cusps

wider

Question 14

The ___ the distance from the rotating condyle, the ____ the angle between the laterotrusive and mediotrusive pathways.

Answer 14

greater

wider
