Dent. Anatmy: ARTICULAR EMINENCE & OVERBITE/OVERJET

Question 1

Rule: The steeper the articular eminence, the ?

Answer 1

LONGER the posterior cusps MAY be to prevent occlusal interference in lateramovment

Question 2

Steeper teeth

Answer 2

more overlap (increase overbite, decreased overjet)

Question 3

What does NOT cause flattening of the posterior cusp tips?

Answer 3

Deep overbite

Question 4

To increase anterior guidance, what would you do the vertical & horizontal overlap?

Answer 4

increase vertical overlap, decrease horizontal overlap

Question 5

Increase in condyle steepness causes an ?

Answer 5

increases vertical overlap

Question 6

Increase vertical overlap

Answer 6

steeper posterior cusp, increase in anterior guidance, more vertical component to mandibular

Question 7

Increase contour of maxillary central incisors will do what?

Answer 7

Increase overjet

Question 8

What happens to the right TMJ when the left canines go from normal occlusion to tip-tip occlusion?

Answer 8

Goes down the eminence

Question 9

Curve of Spree

Answer 9

anterior-posterior Curvature of the Occlusal surface

Question 10

Curve of Wilson

Answer 10

medial-lateral curvature of the occlusal surface

Question 11

Sum of Curve of Wilson + Curve of Spee =

Answer 11

Compensating Curve
