Question 1

Symptoms patient may report as atrophy to the mandibular ridge continues

Answer 1

• Dyesthesia if mand ridge has atrophied below mental foramen, pain, numness of lip
• Compromisisng support stability retention

Question 2

Relationship of contours of master impression to the final denture border

Answer 2

• Need to be the same
• If master impression is thick so will final denture and have too much fullness
• Border molding is imp to determine width thickness height of denture

Question 3

Effect of masseter muscle on width of buccal shelf

Answer 3

• Masseter can create a masseteric notch in the post aspect

Question 4

Structures on post border of max edentulous ridge 2

Answer 4

• Max tuberosity
• Hamular Notch/ Pterygomaxillary fissure

Question 5

Clues to be gained from existing dentures

Answer 5

• VDO, is corners of mouth are over closed inc VDO
• Size, color of teeth inclination

Question 6

Strategies in prothesis design to retard max and mand resorption

Answer 6

• Well adapted and properly extended dentures with proper occlusion
• Retention of residual tooth roots
• Osteointegrated implants
  *

Question 7

Kellys combination syndrome features and tx

Answer 7

• When an edentulous max opposes a partially dentate mand (ant teeth present)
• Syndrome
  
  • Resorption in the premax area
  • Hypertrophy or fibrous hyperplasia of max tuberosity
  • Occlusal plane problems
  • Steep ant guidance
  • No contacts in working, balancing or protrusive during chewing
    *

Question 8

Origin of the keratinized tissue at the crest of edentulous ridge

Answer 8

• Keratinized attached mucosa is the remnant of atttached gingiva that is left after extraction

Question 9

Annual exams for denture pts

Answer 9

• Fit of dentures
• Check for oral cancer
• Dentures should last 10yrs
• 3rd yr reline
• 6 reline

Question 10

Thorough intra and extra oral eval

Answer 10

• Lips and cheeks
• Lateral border of tongue
• Base of tongue
• Floor of mouth
• Tonsillar reegion and soft palate
• Oropharynx
• Neck lymph
• TMJ

Question 11

Relative size changes in arch form as bone resorption progresses

Answer 11

• Max
  
  • Arch form size decreases as bone resorption increases
• Mand
  
  • Arch form size increases as bone resorption increases

Question 12

Factors that change with age and factors that dont change with age relative to dentures

Answer 12

• Decrease with age
  
  • Denture support area, neuromuscular control, chewing force, salivary flow, healing capacity, quality of denture bearing areas,
• Doesnt change
  
  • Desire to have good function, esthetics, and comfort
• PRP/VDR remains relatively constant

Question 13

Are most pts satisfied with their dentures

Answer 13

• Only 5-20% are not
• Satisfaction influenced by
  
  • quality bearing area available
• Always check occlusion first if pt cmplains

Question 14

Signs and symptoms of pressure from denture base on incisive papilla

Answer 14

• Disruption of blood flow and impingement of nerves
• Pt complains of pain and burning sensation

Question 15

Coronoid processes effect upon the maxillary denture border

Answer 15

It can pressure the border of the max denture

Have patient move mand side to side while taking master impression to account for this

Question 16

Changes in facial apperance due to tooth loss

Answer 16

Loss of labial support causes upper lip to look deflated

Lower face squashed

Cheeeks suck in

Inc wrinkles

Appears older

Question 17

Retromolar pad predicts location of…

Answer 17

Mandibular occlusal plane

Question 18

Alginate impression limitations as a master impression material for dentures

Answer 18

• It is more coarse and heavy than PVS
• PVS gives more detail and less distortion

Question 19

How to deal with inflammatory papillary hyperplasia and inflammatory fibrous hyperplasia before making dentures

Answer 19

• Educate pt on removing the denture at night
• Inflammatory FIBROUS hyperplasia (epulis fissuratum)
  
  • surgical excision
• Inflammatory PAPILLARY hyperplasia
  
  • Secondary to poorfitting max denture
  • Mild- antifungal
  • Severe surgical excision

Question 20

What to achieve at wax trial denture placement appt 5

Answer 20

• Verify occlusal plane
• Labial fullness
• Overall apperance
• Phonetics
• VDO

Question 21

Gender specificity of denture tooth moulds

Answer 21

• Male
  
  • Rugged with square teeth and bold central incisors
• Female
  
  • Pronounced curvatures rounded point angles

Question 22

Age appropriate tooth selection

Answer 22

• Young
  
  • tapered, ovoid, rounf teeth
• Middle
  
  • Somewhere in btw
• Old
  
  • Square sharp corners

Question 23

Cusp height selection relative to ridge height

Answer 23

• Lower ridge–> lower cusp height needed
  
  • The poorer the record base stability, the less cusp height
• Flat (low) alveolar ridge=flat teeth (0 degree teeth) bc will have less retention of the ridge to handle high cusp interfernce. Flatter teeth–> less resorption
• Higher ridges (less resorption)= Either 0 or 30 degree teeth
• If present denture has anatomic teeth that arent severly worn and alveolar ridges are not severely resorbed–> cusped teeth
• Good residual ridge height–> Anatomic cusped teeth
• Poor residual ridge height–> Non anatomic flat teeth (monoplane teeth)
• Severe ridge resorption–> Lingualized

Question 24

Characteristics of lingualized denture occlusion

Answer 24

• n protrusive function cusps are protecting the marginal ridges
• Utilizes anatomic teeth for Max and modified nonanatomic teeth for mand
• Tilting forces neutralized
• Allor for increased functional forces in excursions

Question 25

0 degree occlusion

Answer 25

No tooth anatomy

Monoplane occlusion

The cusps of teeth are not present to help denture stay in lace
