Articulation And Occlusion Lecture 2

Front 1

True of False, you must specify what type of occlusion you are talking about. In other words, saying "occlusion" is not as specific as "occlusion of the teeth"

Back 1

True

Front 2

Occlusion of the teeth is a (static/dynamic) position

Back 2

static

Front 3

The rotating condyle is on the (working/balancing) side

Back 3

working

Front 4

The rotating condyle is on the (laterotrusive/mediotrusive) side

Back 4

laterotrusive

Front 5

The working side is the synonymous with (laterotrusive/mediotrusive)

Back 5

laterotrusive

Front 6

The orbiting condyle is on the (working/balancing) side

Back 6

balancing

Front 7

Balancing side is synonymous with (non-working/working) side

Back 7

non-working

Front 8

The orbiting condyle is on the (laterotrusive/mediotrusive) side

Back 8

mediotrusive

Front 9

The non-working side is the synonymous with (laterotrusive/mediotrusive)

Back 9

mediotrusive

Front 10

What is the name of the movement where one juts the jaw forward?

Back 10

protrusive

Front 11

What does CR stand for in terms of occlusion?

Back 11

Centric Relation

Front 12

Centric relation a term that describes the position of the ___ in the TMJ

Back 12

condyle

Front 13

The does CR say about the position of the teeth?

Back 13

NOTHING! Only has to do with position of condyle in TMJ

Front 14

What does ICR stand for in terms of occlusion?

Back 14

Intercuspal position

Front 15

Is it CR or ICR that has to do with the position of the teeth?

Back 15

ICR

Front 16

True or False, most people have ideal CR and ICR at the same time

Back 16

False, 90% do NOT

Front 17

Which of these describes a one-to-one tooth occlusion?

cusp-fossa
cusp-marginal ridge

Back 17

cusp fossa

Front 18

Cusp-marginal ridge is (1 to 2 / 1 to 1) tooth occlusion

Back 18

1 to 2

Front 19

Which is a more desirable occlusion?

cusp-marginal ridge
cusp-fossa

Back 19

cusp-marginal ridge

Front 20

Mutually protected occlusion is also called ___ guided occlusion

Back 20

canine

Front 21

What type of occlusion is ideal?

Back 21

mutually protected occluson

Front 22

In mutually protected occlusion, what teeth hit on the laterotrusive side? Mediotrusive side?

Back 22

laterotrusive - canines only
mediotrusive - no teeth at all!

Front 23

What type of occlusion involves all facial cusps of the lateriotrusive side?

Back 23

unilateral balanced occlusion

Front 24

In unilateral balanced occlusion, what teeth hit on the laterotrusive side? Mediotrusive side?

Back 24

laterotrusive - all facial cusps
mediotrusive - no teeth at all!

Front 25

What type of occlusion is ONLY used for denture patients?

Back 25

bilateral balanced occlusion

Front 26

In bilateral balanced occlusion, what teeth hit on the laterotrusive side? Mediotrusive side?

Back 26

laterotrusive - all facial cusps
meriotrusive - all posterior teeth

Front 27

In optimal occlusion, the condyles are in their most super (posterior/anterior) position, resting on the (anterior/posterior) slopes of the articular eminences

Back 27

anterior, posterior

Front 28

There should be heavier contacts on (anterior/posterior) teeth

Back 28

posterior

Front 29

During protrusive movements, the (anterior/posterior) teeth should disclude immediately

Back 29

posterior

Front 30

During lateral movements, the (mediotrusive/laterotrusive) side is discluded immediately

Back 30

mediotrusive

Front 31

mutually balanced occlusion, unilateral occlusion, and bilateral occlusion are examples of (static/dynamic) occlusion

Back 31

dynamic

Front 32

cusp-marginal ridge occlusion and cusp fossa occlusion are examples of (static/dynamic) occlusion

Back 32

static

Front 33

Which is the most ideal occlusion? (pick one # and one letter)

1. mutually protected occlusion
2. unilateral balanced occlusion
3. bilateral balanced occlusion

A. cusp-fossa
B. cusp-marginal ridge

Back 33

1B

mutually protected, cusp marginal ridge occlusion

Front 34

*What are the 7 requirements of optimum occlusion?

Back 34

1. Both the right and left condyles are in a supero-anterior position in fossae.

2. The articular disc is properly interposed.

3. There is even and simultaneous contact of all teeth.

4. Lighter contacts occur on the anterior teeth than on the posterior.

5. Occlusal forces are directed down long axis of teeth.

6. During laterotrusive movement, the mediotrusive side is discluded immediately.

7. During protrusive movement, all the posterior teeth are discluded immediately.
