Q

fovea palatini (4)

A

unique to humans
coalescence of mucous glands
one on each side of midline
are in general area of the vibrating line. much individual variation. only a guide

26
Q

fovea palatini is in the area of the

A

vibrating line

27
Q

median palatine raphe (midline palatine suture) (2)

A

a bony midline structure, no cushioning effect

may require relief when covered by a denture

28
Q

rugae (2)

A

secondary denture support area

resists anterior displacement of denture

29
Q

incisive papilla (3)

A

landmark for the setting of anterior teeth
pad of CT overlying nasopalatine canal opening
not tolerant of pressure from denture

30
Q

palatal vault form

A

ideal is medium depth, with well defined sugar in anterior

31
Q

if ridges are severely resorbed,

A

inform the patient

u shaped, v shaped

32
Q

torus palatines mau require

A

removal (if on the vibrating line, need to make a posterior seal)

33
Q

where is the posterior palatal seal found

A

distal to junction of hard and soft palates

34
Q

posterior palatal seal

A

glandular and fibrous connective tissue which may be slightly compressed without harm

35
Q

purpose of the posterior palatal seal

A

retention of maxillary CD

36
Q

functions of the posterior palatal seal (4)

A
  1. completes border seal of max CD
  2. compensates for dimensional changes in processed resin
  3. gives firm contact with tissues of soft palate which reduces sagging
  4. presses into tissue making posterior border less conspicuous to tongue
37
Q 
house classification of soft palates 
class 1
class 2
class 3
A 
class 1: >5 mm tissue available, ideal
class 2: 1-5 mm tissue available, adequate
class 3: <1 mm tissue available, poor
38
Q

hoses classifications

A

classification of the soft palate according to hope it drapes

39
Q 
tolerance and location:
class 1 
class 2 
class 3
A 
class 1: easiest to tolerate, broadest range, hardest to locate 
class 2: most common, middle
class 3: easiest to locate, hardest to tolerate
40
Q

mandibular arch anatomy (3)

A

labial frenum
labial vestibule
buccal frenum

41
Q

buccal frenum may contain fibers which attach to “—”, structure at corners of mouth where 8 muscles converge

A

modiolus

42
Q

buccal shelf (4)

A

area posterior to buccal frenum
denture base should cover completely
between height of the ridge and external oblique ridge
resorbs more slowly

43
Q

primary denture bearing area of mandibular denture

A

buccal shelf

44
Q

pterygo mandibular raphe (3)

A

connects from hamulus to the mylohyjid ridge
when prominent, can cause pain, or loosening
requires relief groove if prominent

narrow, ligamentous band extending form pterygoid hamulus ti posterior part of mylohyjid line
buccinator m and superior pharyngeal constrictor muscle fibers enter
limits length of max and mandible CDs

45
Q

retromolar pad (3)

A

soft pad containing glandular tissue
inverted pear shape, posterior border
created from carrying after extractions

an important landmark in removable pros
a triangular pad of soft tissue at posterior end of mandibular residual ridge

46
Q

retromolar pad contents (5)

A
  1. loose submucosa
  2. glandular tissue
  3. fibers of buccinator and sup. pharyngeal constrictor muscles
  4. pterygomandibular raphe
  5. temporalis muscle tendon fibers
47
Q

what happens if retromolar pad is not covered by denture base?

A

excessive resorption of residual ridge

48
Q

lingual frenum (2)

A

anterior attachment of tongue

overlies genioglossus muscle

49
Q

mylohyjid ridge (2)

A

origin of mylohyjid muscle which influences length of lingual flange
can be prominent and or sharp, requiring relief

50
Q

alevolingual sulcus

A

space from lingual frenum to retromylohyoid curtain in posterior

51
Q

retromylohyoid space (3)

A

distal end of lingual sulcus
area posterior to the mylohyjid muscle
good seal aids in retention and stability

52
Q

anatomy of the DL vestibule (5)

A
  1. mylohyjid muscle
  2. palatoglossus muscle
  3. superior constrictor muscle
  4. pterygomandibular raphe
  5. buccinator muscle
53
Q

retromylohyoid fossa

A

denture flange adapts laterally close to body of mandible, producing typical S curve

54
Q

residual ridge (2)

A

a secondary support area

size decreases with time

55
Q

pressure on ridge results in

A

blood supply interrupted, bone resorption

56
Q

we want to minimize pressure and speed out the pressure onto a wider support base, also known as the

A

selective pressure technique

57
Q

resorption is more severe on which arch?

A

mandible than maxillary

58
Q

how long to remove dentures per day

A

8 hr/day to allow tissues to rest

59
Q

proper impression techniques (3)

A

record tissues at rest
denture base extensions using maximum support area
place pressure on those areas that can withstand pressure

60
Q

reducing pressure on residual ridge (2)

A

clinical remount and occlusal refinement at delivery of dentures to patient
no contact of opposing anterior teeth in centric relation
