Q

why is there minimal horizontal and vertical overlap in complete denture

A
  1. minimize forces applied to mand and max anterior ridges in centric
  2. create appropriate relationship of anterior teeth during production of siblant speech sounds
  3. create bilateral balance (so anterior teeth can function properly with most posterior occlusal schemes)

Q

how do you determine what angle teeth to use

A

look at condylar inclination, use teeth of same degree or less

e.g., if CI = 20 degrees, use teeth 20 degree or less

Q

what does balanced articulatin provide

A
  1. natural esthetics
  2. inciasal overlap
  3. centrilized occlusal forces
  4. better bolus penetration

Q

what are the 3 points of contact on anatomic occlusal plane

22
Q

macxillary occlusal plane should project where

A

1 to 2 mm below top of retromolar pad

23
Q

can you set teeth on the ascending ramus of the mandible?

A

NO

24
Q

where must mandibular posterior teeth be positioned

A

over the ridge

25
Q

what does buccal alignment mean

A

teeth should not be set beyond the vestibule. inner land area of cast is absolute limit.

canine and premolars are even
1st and 2nd molars are even

26
Q

what maxillary posterior tooth do you set first when mounting in class I relationship? why?

A

set 1st molar

horizontal overlap prevents cheek biting

27
Q

monoplane occlusion is also called what

A

“flat” occlusion

28
Q

what type of occlusion:
- decreaes lateral forces
- food stability
- good for class II or III patients
- patients that have ridge discrpancy
- simple
- horizontal overlap is critical

A

monoplane occlusion

29
Q

what occlusion:

  • verify maxillary teeth (except lateral incisors) are all on the plane of occlusion
  • both buccal and lingual cusps contact the plane of occlusion
  • correct monoplane mandibular arch
    set up on maxillary teeth before addressing
A

nonanatomic (monoplane) occlusal plane

30
Q

how to create bilateral balance with monoplane

A
  1. add balancing ramps to compensate for Christenen’s phenomenon to idealize stability of mandibular denture

or

  1. position 2nd molar about 15 degree up from occlusal plane
31
Q

what is the term use for the space that ocurs between opposing occlusal surface during mandibular protrusive movement

A

Christensen’s phenomenon

32
Q

maxillary lingual cusps should only contact what of the mandibular posterior teeth

A

central groove

33
Q

maxillary buccal cusps should have how many mm of space between lingual incline of buccal cusp and buccal slop of mandibular bucal cusp

A

1 mm

34
Q

what occlusal scheme are we using for setting posterior teeth in lab? how many degree

A

lingualized posterior teeth 15 degree

35
Q

there should be an ID size card space behind what tooth on both side

A

behind mandibular canines

36
Q

what cusp on what tooth is 0.5 mm above occlusal plane

A

DB/DL cusp of mandibular 1st molar

37
Q

what cusp on what tooth is 1 mm above occlusal plane

A

MB/ML cusp on mandibular 2nd molar

38
Q

what cusp on what tooth is 1.5 mm above the occlusal plane

A

DB/DL 2nd molar

39
Q

what type of occlusion are we setting teeth in lab

A

cross tooth, cross arch bilateral balanced occlusion

40
Q

maxillary buccal cusps should be flared how many mm

A

1 mm

41
Q

in dentures, what are carvings in wax that simulate the contours of the natural tissues that are being replaced by the denture (root anatomy, alveolar bone, gingival roll etc)

A

festooning

42
Q

benefits of a properly contoured denture

A
  1. improved esthetics (especially patient with a high smile line who displays a significant amount of gingiva)
  2. improve tolerance and comfort
  3. improve neuromuscular control and stability of the lower denture (lingual concavity & shape of the buccal shelf of facial side of denture)
  4. limit biting of the lip or cheek
  5. appropriate tongue space for normal speech articulation
43
Q

what must be flat or slightly convex to provide a more natural appearance and prevent food impaction

A

interdental papilla

44
Q

what posteriorly helps deflect the buccal mucosa away from biting surfaces

A

gingival roll

45
Q

what is very important in patients with high smile line (speaking and smiling)

A

gingival contours

46
Q

What are proper contours than minimize biting of lips and cheeks

A

lip contours

47
Q

what contour raises the lip and corner of the mouth

A

maxillary cuspid eminence - lip support and contour

48
Q

what eminences provide lip support and contour

A

maxillary and mandibular cuspid eminence

49
Q

T/F: thickness of labial flange impacts lip contours, this is developed during border molding the impression

A

TRUE

50
Q

what should the palatal thickness be

A

2-3 mm

51
Q

what contour promotes proper speech articular and reduce the incidence of gaggin

A

palatal contour

52
Q

what contour is placed on mandible to deflect food

A

posterior buccal bulge

53
Q

what contour on mandible facilitates stability and control of denture

A

lingual concavity

54
Q

when are you done with denture

A
  1. all teeth set and anatomically waxed
  2. pin at zero and holds shimstock with incisal guide table
  3. posterior teeth hold shim stock
  4. anterior teeth drag shim
