25
why might someone need anti-fungal
no teeth causes folds in mouth
26
what is checked in the intraoral examination of the tongue
size (normal vs large) | Position (normal vs retracted/retruded-35%)
27
what happens to the denture if the floor of the mouth is near the level of the ridge crest
retention and stability is severely compromises
28
what does hyperactive Floor Of Mouth do to a denture
Reduces retenetion and stability
29
what happens to the floor of the mouth if great ridge resorption
Floor of mouth in sublingual and mylohyoid regions spills over the ridge
30
what shape of residual ridge is best
U shape is most favorable for retention and stability
31
favorability of V shaped residual ridge forms
Unfavorable
32
favorability of Flat/shallow/knife edge residual ridge forms
Unfavorable
33
what happens to the dneture with flat/shallow/knife edges residual ridge forms
Resorbed ridges | Poor resistance to lateral forces
34
what happens to denture if maxillary tuberosity is hypermobile
Allows the denture to move
35
problem with maxilary tuberosity that is enlarged with fibrous tissue
the maxillary occlusal plane may be placed too low
36
what must be done with enlarge and fibrous maxillary tuberosities
surgical reduction may be necessary to create adequate interocclusal space for denture bases and teeth
37
why would you do ridge alveoloplasty
Accomodation of Complete denture | Reduction in pressure ulcers
38
Class I soft palate
Large and normal in form with a relatively immovable band of resilient tissue 5-12mm distal to aline drawn across the distal edge of the tuberosities
39
Class II soft palate
MEdium size and normal in form | relatively immovable band of tissue 3-5mm distal to a line drawn across the distal edge of the tuberosities
40
Class III soft palate
the curtain of tissue turns down abrutly 3-5 mm anterior to a line drawn across the distal edges of the tuberosities
41
what are hamular notches
Maximum posterior extent of the maxillary dneture
42
what forms the distal limit of the buccal vestibule
Hamular notches
43
what happens if you over extend the denture from the hamular notch
Inflammation and pain
44
what happens if you under extend a denture in relation to the hamular notch
Non-retentive denture
45
problem with mandibular dentures ridge
Less surface area for retention
46
tongue and floor of mouth to mandibular denture
interfere with retention
47
where is the keratinized attached mucosa of the mandibular ridge
onfined to the alveolar ridge
48
what happens if youover extend a mandibular denture
displaced
49
resorption rate of mandible vs maxilla
mandible is 4x faster
50
what makes up the buccal shelves
Dense cortical bone
51
do the buccal shelves resorb
No, due to muscle attachment
52
problem with frenum in the mandibl
can affect denture extensions
53
what is the retromolar pad
Triangular pad of tissue at the distal end of the residual ridge
54
what is found under the retromolar pad
dense cortical bone due to muscle attachment reistant to resorbition
55
why does the retromolar pad matter to dentures
must be covered for suppor and lack of long term cortical bone resptions Creates peripheral seal
56
what does the retromylohyoid space determines
The posterior extension of the mandibular denture lingual flange - determines stability and retention
57
what does Prognosis based on
``` bearing surface anatomy ability to reproduce CR Tongue Position Floor of mouth posture Neuromuscular control Dental history Psychological classification ```
58
what should preliminary impression do
Accurate rep of anatomical lands that permites fabrication of properly extended custom tray
59
what to do if someone has really problemmatic extraoral features
talk to a specialists
60
facial form may help with what
Class I, II, and III in addition to the shape of teeth
61
how far can mucosa displace
2mm
62
can you do dnetures on someone with a problem
No
63
ideal ridge shape
Class I
64
CLass II ridge
High palatal vaul, compromising retention
65
Class III ridge
ovoid, xombo of I and II
66
what is the appointments order for Dentures
1. examination, diagnoses and preliminary impressions - custom tray fabrication 2. definitive edentulous impressions - master casts poured 3. Maxillomandibular relationship - teeth are placed in 4. esthic try-in for CR, VDO verification 5. Delivery
67
setting time for alginate
3-4 min
