19
Q

What is the unfavorable interarch space?

A

Too little space or too much space (torque lever is applied to denture bases)

20
Q

What is the ideal ridge form?

A

Square to gently rounded

21
Q

What is the unfavorable ridge form?

A

Tall, thin, undercut

22
Q

What is the ideal mm of tuberosities?

A

ideal: 5-6mm
minimum: 4mm

23
Q

What happens if you have unilateral or bilateral undercuts?

A

Unilateral - may be ok
Bilalteral - may need surgical correction

24
Q

What happens if you have sharp area of ridge?

A

Surgery needed

25
Q

What is a palatal torus?

A

Bony enlargement at midline of hard palate

26
Q

What is the frequency of palatal torus?

A

20-25% of population
More prevalent in women
Maximum size in 3rd or 4th decade

27
Q

When should a palatal torus be removed?

A

Large and fills palatal vault
Is undercut
Encroaches on vibrating line
Pnt is concerned that its cancer

28
Q

What is mandibular tori?

A

Dense cortical bone covered by a very thin layer of mucous membrane

29
Q

What is mandibular tori susceptible to?

A

Irritation from denture base

30
Q

What is the best treatment for mandibular tori?

A

Surgical removal

31
Q

What is the ideal depth of the palatal vault?

A

Medium depth with well-formed rugae

32
Q

What happens to a flat palatal vault?

A

Poor resistance to horizontal movement of denture

33
Q

What happens to a high, narrow, deep palatal vault?

A

Rapid break of peripheral seal and poor retention

34
Q

What is an ideal border attachment?

A

Muscle/frenum attachments are 10mm or more from crest of ridge

35
Q

What is an unfavorable border attachment?

A

Attachments near crest of ridge and may interfere with peripheral seal

36
Q

What are major impact areas of the tongue and complete dentures?

A

Border seal
Tooth placement
Speech

37
Q

What is normal tongue position?

A

Fills floor of mouth
Lateral borders lie on post. alveolar ridge
Apex approximates ant. alveolar ridge

38
Q

25% of edentulous patients have…

A

Retruded tongue
- border seal is absent
- stabilizing influence of tongue is absent
- retention/function of mandib. CD difficult

39
Q

What does an enlarged tongue cause?

A

Constant dislodging force on mandibular denture
- adaptation to denture may require MONTHS of dedicated effort

40
Q

What plays an important role in denture retention?

A

Saliva

41
Q

What are some things we should know about a pts denture history?

A

Years edentulous?
Previous dentures/current dentures
Successful
Expectation? Attainable?
Multiple sets of dentures made in a short time - not a good sign

42
Q

What should you do with existing dentures?

A

Evaluate and make impressions

43
Q

What is the prosthodontic diagnostic index?

A

A tool that every clinican can use to communicate to colleagues and patients the challenges each patient present with his or her unique dental condition

44
Q

What are prosthodontic diagnostic index checklist items?

A
  1. Bone height mandibular
  2. Residual ridge morphology of maxilla
  3. Muscle attachments in mandible
  4. Maxillomandibular relationship
  5. Conditions requiring pre-prosthetic surgery
  6. Limited inter-arch space
  7. Tongue anatomy
  8. Modifiers
45
Q

Describe the PDI classifications for compelte edentulism

A

Class I — straightforward.
Class II – denture-supporting anatomy degraded.
Class III - anatomy degraded; surgical revision
needed; additional factors present.
Class IV – most debilitated edentulous condition
