Q

• Elimination of occlusal errors in non-anatomical teeth

A

o First adjustment is posterior maxillary with very fine sandpaper

Q

Mandible resorbs 4x slower than maxilla T o F

A

False

23
Q

T o F maxilla absorbs inwards, while mandible absorbs downward and forward.

A

*T

24
Q

The foundation for odentogenic restoration is ———— of the patient.

Attitude, personality, desires, essence.

A

desires

25
Q

• Problems with Mastication- Incisor support limited, so

A

canine area is better for “incising”; smaller portions easier to chew and some foods will be off limits (extremely hard/chewy/sticky foods)

26
Q

o Disharmony in occlusion →

A

lesions

o Lesions on palate and crest of residual ridges are usually small, well circumscribed and indurated

27
Q

o Hyperemic lesions- due to

A

bone spur, area of exostosis or foreign body; usually presents later

28
Q

o Severe irritation- detaching of overlying mucosa especially on the

A

mylohyoid ridge, cuspid eminences, alveolar tubercles and bone exostoses; due to denture flange during insertion and removal of denture or friction during function

29
Q

o Hypertrophy- occurs in

A

midpalatal suture area, small nodules develop due to poor fitting prosthesis with poor retention

30
Q

o Insufficient interocclusal distance →

A

generalized soreness of crest and slopes of ridge along with pain in elevator muscles of mandible

31
Q

o Commisural chelitis- inflammation of

A

angles of mouth due to excessive interocclusal distance (closing down too much in CO)

32
Q

• Usually lack of retention in retromolar pad area =

A

anterior dislodging

33
Q

o Dislodgement during rest is usually due to

A

underfilling/inadequate seal/ too much or too little saliva
• Slow loss of retention → saliva
• Sudden loss → mechanical problems

34
Q

Elevate 2nd molar by 1.5mm to

A

emulate curve of spee

35
Q

Class II or III, consider using

A

monoplane occlusion

36
Q

Monoplane can be unstable if

A

condylar guidance is steep.

38
Q

——— is the starting point for an esthetic evaluation

A

Facial midline

39
Q

Maxilla resorbs ——-, mandible resorbs ——–

A

inward

downward and outwards

40
Q

With the lips at rest, a youthful appearance of an unworn dentition will display between

A

2 and 4 mm of the central incisors.

41
Q

When the Patient smiles the smile curve should fall within

A

50-80% of the distance between the upper and lower lip.

42
Q

Average W/L ratio for the central incisors is

A

75-80%.

43
Q

Order of checking

A

Denture base, borders, occlusion, phonetics, polish, instruction, recall

44
Q

Sublingual crestal area

A

overextended

45
Q

remount - use wet guaze to

A

block out undercuts

46
Q

Place two cotton rolls on the first molar denture teeth and have the patient close on these cotton rolls for 5 minutes. This allows

A

optimal denture adaptation and seating the PPS area.

47
Q

Concave parts of mandibular denture aid in

A

retention

48
Q

Maxillary contours aid in

A

speech

In the canine premolar area there should be a gentle concave contour of the denture base extending from the palatal surface of these teeth to the horizontal shelf of the palate. (“s” sounds)

49
Q

Horizontal plaster and land areas are lubricated prior to the second pour to

A

facilitate separa6on of the flask

50
Q

Diatorics added for

A

mechanical reten6on - drilling into the bottom of a denture tooth before adding acrylic

51
Q

If the cast has undercuts, a small amount of

A

dough is placed into the undercut areas before the trial pack.

52
Q

Thin plas6c sheet is placed between the

A

two halves of the flask until the final press.

53
Q

Sibilant sounds: mand travels

A

downward and forward. Greatest in class II. IO = 5 mm with sibilant sounds. This tells you that: VDO is insufficient.
