ACP PDI Complete Edentulism

Question 1

Type A maxilla form (5)

• Vestibule?
• Palate?
• Tuberosity?
• Pterygomaxillary fissure?
• Tori?

Answer 1

1. Vestibular vertical depth that resists vertical/horizontal movement of denture base
2. Palatal movement that resists vertical and horizontal movement of denture
3. Sufficient tuberosity definition that resists movement
4. Pterygomaxillary fissure well defined to establish posterior extension of denture base
5. Absence of tori/exostoses

Question 2

Type B maxilla form (4)

• Loss of what vestibule?
• Tuberosity/pterygomaxillary fissure?
• Tori?
• What kind of palatal vault morphology?

Answer 2

1. Loss of posterior buccal vestibule
2. Tuberosity/pterygomaxillary fissure poorly defined compromising delineation of posterior extension
3. Palatal/lateral tori are rounded and do not affect posterior extent of denture base
4. Palatal vault morphology resists vert/horizontal movement

Question 3

Type C maxilla form (6)

• Loss of what vestibule?
• Prominent what?
• Tori?
• Hyperplastic what?
• Palatal vault morphology?
• What about the post mylar space?

Answer 3

1. Loss of anterior labial vestibule
2. Prominent midline suture
3. Palatal/lateral tori with bony undercuts that do not affect posterior extension of denture base
4. Hyperplastic mobile anterior ridge that offers minimal support/stability
5. Palatal vault morphology that offers minimal resistance to movement
6. Reduction of post malar space during mand. opening and/or excursive movements

Question 4

Type D maxilla Form (5)

• Vestibule?
• Tori?
• Anterior ridge?
• Palatal vault?
• Prominent what?

Answer 4

1. Loss of anterior labial/posterior buccal vestibule
2. Tori rounded or undercut that interferes with posterior border of denture
3. Hyperplastic, redundant anterior ridge
4. Palatal vault does not resist vertical/horizontal movement
5. Prominent anterior nasal spine

Question 5

Type A muscle attachments

Answer 5

Adequate attached mucosal base w/o undue muscle impingement during normal function

Question 6

Type B muscle attachment

• Adequate attached mucosal base except where?
• What muscle attachment is high?

Answer 6

Adequate attached mucosal base in all regions except anterior buccal vestibule - cuspid to cuspid

High mentalis muscle attachment

Question 7

Type C muscle attachment
- Adequate attached mucosal base except where?

• What muscle attachments are high?

Answer 7

Adequate attached mucosal base everywhere except anterior buccal and lingual vestibules - cuspid to cuspid

High genioglossus and mentalist muscle attachments

Question 8

Type D muscle attachment

• Adequate attached mucosal base except where?
• What muscle attachments are high?

Answer 8

Adequate attached mucosal base only in posterior lingual region

All other regions detached

Question 9

Type E muscle attachment

• Adequate attached mucosal base except where?
• Cheek and lip movement = what?

Answer 9

No attached mucosa in any region

Cheek and lip movement = tongue movement

Question 10

At what overall Classification level do minor modifiers, psychosocial considerations, mild systemic disease with oral manifestations and localized soft tissue conditions begin?

Answer 10

Class 2

Question 11

What Classification is characterized by the need for surgical revision of denture supporting structures for adequate Prosthodontic function?

Answer 11

Class 3
