Dent. Anatmy: ARTICULAR EMINENCE & OVERBITE/OVERJET Flashcards
Rule: The steeper the articular eminence, the ?
LONGER the posterior cusps MAY be to prevent occlusal interference in lateramovment
Steeper teeth
more overlap (increase overbite, decreased overjet)
What does NOT cause flattening of the posterior cusp tips?
Deep overbite
To increase anterior guidance, what would you do the vertical & horizontal overlap?
increase vertical overlap, decrease horizontal overlap
Increase in condyle steepness causes an ?
increases vertical overlap
Increase vertical overlap
steeper posterior cusp, increase in anterior guidance, more vertical component to mandibular
Increase contour of maxillary central incisors will do what?
Increase overjet
What happens to the right TMJ when the left canines go from normal occlusion to tip-tip occlusion?
Goes down the eminence
Curve of Spree
anterior-posterior Curvature of the Occlusal surface
Curve of Wilson
medial-lateral curvature of the occlusal surface
Sum of Curve of Wilson + Curve of Spee =
Compensating Curve
