1
Q

What are the goals of occlusal Equilibration

A
  • To improve functional and esthetic relationships between maxillary and mandibular teeth
  • To eliminate TMD
2
Q

When should you perform permanent occlusal therapy?

A

Only when significant evidence exists to support that the occlusal condition is an etiological factor

3
Q

What are difference ways to perform occlusal therapy?

A

Selective grinding
Fixed prosthodontics
Orthodontic therapy
Orthognathic surgery

4
Q

Orthognatic surgery

A

A combination of ortho and surgery

5
Q

What are factors influencing treatment planning?

A
Symptoms
Condition of the dentition
Systemic health
Esthetics
Finances
6
Q

Vertical overlap

A

The functional cusps of teeth overlap

  • buccal slope of maxillary lingual cusp
  • lingual slope of the mandibular buccal cusp
7
Q

What is the rule of thirds

A

divide the slopes of the cusps into 1/3s, and whichever 1/3 the contact is in will tell us what sort of therapy to do

8
Q

Contact is in the inner 1/3

A

Selective grinding can help

9
Q

Contact is in the middle 1/3

A

Fixed prosthodontics can help

10
Q

Contact is in the outer 1/3

A

May need ortho

11
Q

Selective grinding

A

A procedure by which the occlusal surfaces of the teeth are altered to improve the overall contact pattern
Appropriate only when alterations of the tooth surfaces are minimal so that all corrections can be made within the enamel structure

12
Q

Selective grinding on shorter cusp slides

A

More likely can be accomplished within the confines of the enamel

13
Q

Selective grinding on longer cusp slides (with flatter teeth)

A

Becomes more difficult to eliminate the interference within the confines of the enamel

14
