Occlusal Considerations

Question 1

what are the baseline for evalulating patients occlusion?

Answer 1

• teeth
• TMJ
• Musculature

Question 2

What are the goals for direct restorations

Answer 2

• minimize trauma
• preserve structures
• promote longevity
• restore mastication

Question 3

in most clinical situations occlusal contacts on direct restorations are

Answer 3

created in MIP and excursive movements

harmony with pt occlusion

Question 4

what is the static relationship between the incising amd asticating surfaces of the max and man teeth or tooth analogues

Answer 4

occlusion

Question 5

the static and dynamic contact relationship between occlussal surfaces of teeth during fuction

Answer 5

articulation

Question 6

you need to ______ pt occlusion before starting tx

Answer 6

understand and evaulate

Question 7

for optimal functional occlusion posterior teeth (stationary)

Answer 7

• mulitple even bilateral and simultaneous contacts
• mandible in CR
• axial loading

Question 8

the teeth in the posterior are loaded

Answer 8

axial

Question 9

axial loading

Answer 9

forces directed over the long axis of the tooth

Question 10

what happens if teeth are not loaded axial?

Answer 10

• cracks/ fractures
• tramua to PDL and bone
• wear on the teeth
• possible trauma to TMJ

Question 11

for optimal functional occlusion anterior teeth (stationary)

Answer 11

• lighter contacts than post
• ot loaded axial (can’t high loads)

Question 12

why should anterior teeth have contacts?

Answer 12

• if they do not they will super erupt
• wont happen equal so can cause shifting

Question 13

what are the optimal occlusal relationships for excursve movements?

Answer 13

• canine guidance
• anterior guidance

Question 14

laterotrusive side (right lateral movement)

Answer 14

canines on this side guide the movement

working side

Question 15

mediotrusive side (right lateral movement)

Answer 15

no teeth should contact on this side

Question 16

if teeth contact on the mediotrusisve side they would have

Answer 16

off-axis loading

Question 17

If in excursive movements, canine guidance and anterior guidance
are not present, then ____________

Answer 17

OCCLUSAL INTEFERENCES are present

Question 18

what is an unwanted (or premature) interocclusal contact

Answer 18

Occlusal Interference:

Question 19

what are the two Philosophies for Interocclusal Contacts?

Answer 19

• Cusp-Fossa contacts
• Cusp-Marginal Ridge contacts

Question 20

in cusp-fossa Each functional cusp occludes

Answer 20

fossa of the opposing tooth

Question 21

cusp-fossa is a tooth to

Answer 21

Tooth arrangement

Question 22

when is cusp-fossa used

Answer 22

when restoring both
opposing quadrants of teeth

Question 23

in Cusp-Marginal Ridge Each Functional cusp contacts

Answer 23

the marginal ridges
of opposing pair of teeth or fossae of opposing teeth

Question 24

Cusp-Marginal Ridge is a one tooth to

Answer 24

two teeth arrangement

Question 25

The majority of natural dentitions have

Answer 25

Cusp-Marginal Ridge

Question 26

Cusp-Marginal Ridge is commonly used for

Answer 26

single restorations

Question 27

The cusp-marginal ridge occlusal relationship allows for

Answer 27

**some **cusps to occlude onto marginal ridges and some others to occlude
into fossae.

Question 28

The cusp-fossa relationship allows

Answer 28

only for each cusp to occlude
into one fossa.

Question 29

this is

Answer 29

cusp-fossa

Question 30

this is

Answer 30

cusp-marginal ridge

Question 31

what are the four inclines present on all cusps?

Answer 31

facial, lingual, mesial, and distal

Question 32

what is a non optimal occluusal contacts

Answer 32

rounded cusp

Question 33

Create a ____________, halfway up a cuspal incline, that is ____________, to serve as a cusp seat

Answer 33

plateau; perpendicular
to the long axis of the tooth

when not in ideal postion

not normal location

Question 34

you can use _______ to evalulate occlusal contacts

Answer 34

shim stock

Question 35

what area do you need to adjust if this is the contact

Answer 35

B

Question 36

when removing the high spot in what do you remove

Answer 36

only the center of the mark (bull’s eye)

Question 37

what teeth guide protrusive movement?

Answer 37

anterior teeth
