q1

Question 1

The plane of occlusion is the plane that would be established if a line were drawn through all the buccal cusp tips and incisal edges of the mandibular teeth and then ______ into a plane to include the lingual cusp tips and continuing across the arch to include the buccal and lingual cusp tips of the opposite side.

Answer 1

broadened into a plane

Question 2

The occlusal table represents approximately ____% of the total buccolingual dimension of the posterior tooth

Occlusal table is positioned over the _____ axis of the tooth structure.

Answer 2

50% to 60%

long axis

Question 3

Supporting cusps aka

Answer 3

centric cusps, functional (Maxillary palatal and mandibular buccal cusps)

Question 4

Guiding cusps aka

Answer 4

non-centric, guiding, shearing

Question 5

When posterior ____exists, the mandibular lingual cusps occlude in the central fossae of the maxillary teeth and the maxillary buccal cusps occlude in the central fossae of the mandibular teeth.

Answer 5

cross bite

Question 6

The Guiding Inclines(GI) of the maxillary teeth are thesurfaces responsiblefor thecharacteristics of _____.

Answer 6

anterior guidance.

Question 7

The area that supports the major forces of mastication is?

Answer 7

OCCLUSAL TABLE

Question 8

Mandibular MotionWhat are we looking at when the mandible moves ?

Answer 8

1) Teeth
2) Condylar movement

When the mandible moves BOTH the teeth and the condyles alsomove in space, obviously since they are both components of the mandible.

Question 9

What are we doing to analyze mandibular movement ?

Answer 9

We are tracing or recording these movements (tooth and condylar movements) from 3 spatial planes (Sagittal, Frontal & Horizontal)

Question 10

Five Factors of Mandibular Movement

Answer 10

1)Initiating position (Centric Relation)2)Types of Motiona)Rotationb)Translation3)Direction of Motion (Planes)4)Degree of Movement5)Clinical Significance of Movements

Question 11

Condylar position is most anterior when

Answer 11

mandible is at maximum opening

Question 12

Answer 12

Border movements ALWAYS start in CR in ALL planes

Question 13

Functional border ALWAYS starts in ____

Answer 13

Functional border ALWAYS starts in MIP (ICP )

It is tear shaped

Question 14

Answer 14

Left lateral superiorborder starts at CR
