Final; Principles of Occlusal Equilibration

Question 1

What are the two main goals of occlusal equilibration

Answer 1

1. to improve functional and esthetic relationships between maxillary and mandibular teeth
2. to eliminate TMD

Question 2

Permanent occlusal therapy is indicated only when what

Answer 2

there is significant evidence to support that the occlusal condition is an etiological factor

Question 3

The best choice is to perform the least amount of dental alterations that will fulfill treatment goals; what are the for different treatments ranging from least to most invasive

Answer 3

1. selective grinding
2. fixed prosthodontics
3. orthodontic therapy
4. orthognathic surgery

Question 4

What is one major spot on the teeth you would not grind

Answer 4

the functional cusp; the functional cusp takes up 60% of a tooth

Question 5

What location on the mandibular and maxillary teeth is important to note

Answer 5

lingual slope of the buccal cusp (mand)
bucal slope of the lingual cusp (max)
These slopes vertically overlap in ideal occlusion; a location for selective grinding if need be

Question 6

This will determine whether a patient undergoes selective grinding, fixed prosthodontics, or orthodontic treatment

Answer 6

the rule of thirds; the point of contact determining the procedure

Question 7

What five factors influence treatment planning

Answer 7

symptoms
condition of the dentition
systemic health
esthetics
finances

Question 8

This is a proceed in which the occlusal surfaces of the teeth are altered to improve the overall contact pattern

Answer 8

selective grinding

Question 9

When is selective grinding appropriate

Answer 9

only when alterations of the tooth surfaces are minimal so that all corrections can be made within the enamel surface

Question 10

The shorter or longer the slide is; the more likely that selective grinding can be accomplished within the confines of enamel

Answer 10

shorter the slide

Question 11

When the slide has a great what component, it becomes difficult to eliminate within the confines of enamel

Answer 11

horizontal

Question 12

Tooth alignment and the centric relation slide are more easily evaluated on what

Answer 12

mounted casts

Question 13

Where is selective grinding performed first so the final results can be visualized

Answer 13

on the mounted casts

Question 14

Selective grinding is like this analogy

Answer 14

hammer and anvil

the functional cusp is the hammer so do to grind away it; only like deepen the fossa/slopes, etc. of the occlusal table

Question 15

What are the three steps to take when determining mandibular excursions

Answer 15

locate teeth in the arch
determine if it moves
identify the movement

Question 16

If the deviation in closing is forward which inclines should you grind

Answer 16

MUDL
mesial upper
distal lower

Question 17

If the deviation on closing is toward the cheek, which inclines should you grind

Answer 17

BULL
buccal upper
lingual lower

Question 18

If the deviation on closing is toward the tongue, which inclines should you grind

Answer 18

LUBL
lingual upper
buccal lower

Question 19

If the deviation on opening is from non-working interferences such as the path from centric toward the tongue, what inclines should you grind

Answer 19

BULL
buccal upper
lingual lower

Question 20

If the deviation on opening is from non-working interferences such as a crossbite with balancing interferences, what should you grind

Answer 20

BULL

both the buccal incline of the upper and the lingual incline of the lower

Question 21

If the deviation on opening is from working interferences such as the working side pathway, what would you grind

Answer 21

LUBL

lingual incline of buccal and buccal incline of lower

Question 22

If the deviation on opening is from protrusive interferences such as the protrusive pathway, what should you grind

Answer 22

DUML
distal upper (more often)
