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"
|
True
|
|
Occlusion of the teeth is a (static/dynamic) position
|
static
|
|
The rotating condyle is on the (working/balancing) side
|
working
|
|
The rotating condyle is on the (laterotrusive/mediotrusive) side
|
laterotrusive
|
|
The working side is the synonymous with (laterotrusive/mediotrusive)
|
laterotrusive
|
|
The orbiting condyle is on the (working/balancing) side
|
balancing
|
|
Balancing side is synonymous with (non-working/working) side
|
non-working
|
|
The orbiting condyle is on the (laterotrusive/mediotrusive) side
|
mediotrusive
|
|
The non-working side is the synonymous with (laterotrusive/mediotrusive)
|
mediotrusive
|
|
What is the name of the movement where one juts the jaw forward?
|
protrusive
|
|
What does CR stand for in terms of occlusion?
|
Centric Relation
|
|
Centric relation a term that describes the position of the ___ in the TMJ
|
condyle
|
|
The does CR say about the position of the teeth?
|
NOTHING! Only has to do with position of condyle in TMJ
|
|
What does ICR stand for in terms of occlusion?
|
Intercuspal position
|
|
Is it CR or ICR that has to do with the position of the teeth?
|
ICR
|
|
True or False, most people have ideal CR and ICR at the same time
|
False, 90% do NOT
|
|
Which of these describes a one-to-one tooth occlusion?
cusp-fossa cusp-marginal ridge |
cusp fossa
|
|
Cusp-marginal ridge is (1 to 2 / 1 to 1) tooth occlusion
|
1 to 2
|
|
Which is a more desirable occlusion?
cusp-marginal ridge cusp-fossa |
cusp-marginal ridge
|
|
Mutually protected occlusion is also called ___ guided occlusion
|
canine
|
|
What type of occlusion is ideal?
|
mutually protected occluson
|
|
In mutually protected occlusion, what teeth hit on the laterotrusive side? Mediotrusive side?
|
laterotrusive - canines only
mediotrusive - no teeth at all! |
|
What type of occlusion involves all facial cusps of the lateriotrusive side?
|
unilateral balanced occlusion
|
|
In unilateral balanced occlusion, what teeth hit on the laterotrusive side? Mediotrusive side?
|
laterotrusive - all facial cusps
mediotrusive - no teeth at all! |
|
What type of occlusion is ONLY used for denture patients?
|
bilateral balanced occlusion
|
|
In bilateral balanced occlusion, what teeth hit on the laterotrusive side? Mediotrusive side?
|
laterotrusive - all facial cusps
meriotrusive - all posterior teeth |
|
In optimal occlusion, the condyles are in their most super (posterior/anterior) position, resting on the (anterior/posterior) slopes of the articular eminences
|
anterior, posterior
|
|
There should be heavier contacts on (anterior/posterior) teeth
|
posterior
|
|
During protrusive movements, the (anterior/posterior) teeth should disclude immediately
|
posterior
|
|
During lateral movements, the (mediotrusive/laterotrusive) side is discluded immediately
|
mediotrusive
|
|
mutually balanced occlusion, unilateral occlusion, and bilateral occlusion are examples of (static/dynamic) occlusion
|
dynamic
|
|
cusp-marginal ridge occlusion and cusp fossa occlusion are examples of (static/dynamic) occlusion
|
static
|
|
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 |
1B
mutually protected, cusp marginal ridge occlusion |
|
*What are the 7 requirements of optimum occlusion?
|
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. |
