Question

When vertical overlap is increased, the cusps of the posterior teeth can be ___ and vice versa.

A) Rounded
B) Sharpened
C) Shortened
D) Elongated

Answer 1

When vertical overlap is increased, the cusps of the posterior teeth can be shortened and vice versa.

Step-by-step explanation:

When vertical overlap is increased, the cusps of the posterior teeth can be shortened and vice versa. The cusps of the posterior teeth refer to the pointed or rounded edges on these teeth. When there is increased vertical overlap, it can lead to wear and tear on the cusps, causing them to become shorter. On the other hand, if the vertical overlap is decreased, the cusps can become longer.
