21
Q

The Non-working pathway of the mandibular cusps positioned over the maxillary teeth…

A

22
Q

The non-functional area is ________ than the functional area.

A

Larger

23
Q

Path of the Left working cusp (centric cusp) during laterotrusive movement of the distolingual cusp on the maxillary first molar?

A

Through the lingual embrasure between the first and second premolars.

24
Q

Path of the non working mesiofacial cusp on the maxillary first molar during laterotrusive movement

A

Mesiofacial grove to the central fossa, and through the lingual groove of the mandibular first molar.

25
Q

Name the boarder movements of the most superior, anterior, and inferior in the sagittal plane respectively.

A

Maximum intercuspation
Maximum protrusion point
Max opening point

26
Q

Name the most anterior, posterior, and Lateral boarder movements in the frontal plane

A

Posterior: Centric relation
Anterior: max protrusion
Lateral: Extreme Right/Left Lateral movement

27
Q

The boarder movement in the frontal plane that is not visible

A

Centric relation is obscured by maximum intercuspation

28
Q

The correlation of all movements at the condyle level.. Where all movements cross eventually.

A

Centric Relation

29
Q

Factors that determine the hight of cusps and depth of

Fossa.

A

Vertical factors

30
Q

Factors that influence the direction or location of the ridges and groves and placement of cusps.

A

Horizontal factors

31
Q

Determines the amount of vertical movement the mandible can go through.

A

The steepness of the angle of the lingual surface of the anterior teeth.

32
Q

Every point on the mandible will move away from the horizontal reference plane if…

A

The PCF (condyle joints), and the ACF (anterior teeth) have the same angle.

33
Q

The factor that limits the movement of the nonworking condyle.

A

Morphology of the medial wall of the fossa, and the tempromanbular ligament of the working fossa.

34
Q

The two fixed variables in occlusal morphology

A
  1. Condyle guidance angle

2. Mandibular lateral translation, aka Bennet Movement

35
Q

What happens when a tooth is further away from the axis of rotation.

A

The wider the angle formed by the latter/mediotrusive pathways.

36
Q

As mandibularlaterl translation increases…

A

The angle between two the two latter/mediotrusive pathways also increases.
