Test 1.2

Question 1

temporomandubular joint is innervated by the _____ nerve that provides motor and sensory inntervation to the muscle that control it. This is primarily the _______ ______

Answer 1

Same, Trigeminal nerve

Question 2

What is most of the innervation of the temporomandibular joint provided by?

Answer 2

Auriculotemperal nerve (75%)

Question 3

in addition to the auriculotemperal nerve, what other innervation is there for the temporomandibular joint?

Answer 3

(sensory) deep temporal and massenteric (V3)

Question 4

Primary vascularization for the temporomandubular joint is provided by?

Answer 4

superficial temporal branch and the external carotid artery

Question 5

The condyle recieaves vascular supply through its _______ _____ from the inferior alveolar artery and ________ _______ from other branches that perforate the head from various angles

Answer 5

marrow spaces, feeder vessels

Question 6

Three traits of the maxillary arch

Answer 6

Larger, Wider, Esthetics are embedded more in the maxillary arch then in the mandible.

Question 7

What are the only two teeth to only have one opposing tooth?

Answer 7

mandibular central incisor, maxillary third molar

Question 8

Traits of the plane of occlusion (4)

Answer 8

• Ideal plane not flat (flat plane allows for too many contacts on posterior teeth)
• proper plane of occlusion will permit simultaneous functional contacts to occur
• Curved plane allows maximum use of tooth contacts during function
• the teeth are stratigically positioned in the ARCHES at varied and coordinated degrees of inclination

Question 9

How much less force is exerted on premolars then the third molars?

Answer 9

approximately 50% less force

Question 10

What is considered a MORE STABLE occlusal contact?

Answer 10

Occur between a cusp tip and the depth of a fossa, or between a cusp tip and a flat surface

Question 11

What is considered a LESS STABLE occlusal relationship?

Answer 11

When contacts occur on cuspal inclines

Question 12

Class 1 Ideal occlusion

Answer 12

• Ideal 1st molar relationship

- Ideal canine relationship

Question 13

Class 1 Malocclusion

Answer 13

• Ideal 1st molar
• NON-IDEAL canine relationship
• Rotated or overinclined teeth

Question 14

Class 2 malocclusion

Answer 14

• Distally positioned first and canine relationships

- Excessive anterior horizontal overlap

Question 15

Class 3 malocclusion

Answer 15

• Mesially postiioned first molar relationship and canine relationships
• negative horizontal overlap

Question 16

occlusal contact should occur between a cusp tip and…

Answer 16

the depth of an apposing fossa (cusp-fossa occlusion)

Question 17

Review slide

Answer 17

19 on marginal ridge location

Question 18

What are some side effects of Bruxism?

Answer 18

EXCESSIVE WEAR, FRACTURES, and other signs and symptoms of occlusal disease

Question 19

What is termed the “NON-WORKING SIDE”?

Answer 19

the left or opposite side (when moving mandible to the right)

Question 20

Describe the working vector

Answer 20

parallel to the lingual groove and travels toward the tongue

Question 21

What is the NON-FUNCTIONAL PATHWAY?

Answer 21

The area that the mandible CANNOT normally move into.
