Q

What is the PIP sequence?

A
  1. dry denture surface

Q

What should you remove on the cast after applying paste?

A

islands of pink

Q

How should you check the phonetics?

A
  • check the thickness of the maxillary palatal portion (a common problem is excessive thickness)
  • reevaluate the position of the maxillary anterior teeth
  • if everything appears normal it nay be a matter of time for the patient to adapt
  • open vertical dimension of occlusion

Q

Why does a patient gag?

A
  • palate excessively thick
  • palatal extension too long
  • lack of tongue space (teeth set too far to the lingual)

Q

What are sources of occlusion errors?

A
  • Resin shrinkage when processed
  • Ill-fitting temporary record bases
  • Change of OVD on the articulator
  • Inaccurate max-mand. records by dentist
  • Incorrect arrangement of teeth
  • Overheated when polished
  • Water absorption (expands 1-3%)
21
Q

Since numerous sources of occ. errors exist, what should the dentist assume?

A

Errors exist and work to find it

22
Q

What does technique for cheking occlusal errors require?

A

A willingness to see the error

23
Q

What happens if you simply tell patient to close the jaw and observe contacts?

A

The error is unlikely to be detected

24
Q

What is occlusal harmony?

A

Patient comfort
“efficient” function (20% of natural teeth)
Preserve supporting tissues

25
Q

How should you occlude the completed dentures first?

A

Hand occlude

26
Q

What should you look for beyond the tooth contacts?

A

Posterior flange contacts

27
Q

What should you do prior to making the record?

A
  • seat the posterior paltal seal
  • place two cotton rolls between the posterior teeth and have the patient bite down for 5 min
28
Q

How do you make the clinical remount?

A
  • make interocclusal record
  • remount dentures on articulator
  • refine occlusion on articulator
29
Q

When is clinical remount and occlusal refinement done?

A

Before final delivery of the dentures

30
Q

What do occlusal errors deform?

A

The supporting tissues and conceal the errors if postponed

31
Q

What allows the dentures to move?

A

Resiliency of tissues
Misleading articulating paper markings result

32
Q

What interferes with paper markings?

A

Salive on teeth

33
Q

What does intraoral occlusal “adjustment” require?

A

Reoeated patient cooperation
- some can cooperate, others cannot

34
Q

What should you use as extra security during the intraoral occlusal adjustement?

A

Denture adhesive powder

35
Q

What are advantages for clinical remount?

A
  • reduce patient participation
  • dentist sees better what to do
  • stable working foundation; bases not shifting on resilient tissues
36
Q

What does absence of saliva create?

A

More accurate marks with articulating paper

37
Q

Where should grinding be done?

A

Away from patient. This prevents patient objections to “mutilating my new teeth”

38
Q

What is desired occlusion?

A

Simultaneous contact of all posterior teeth in the retruded mandibular position (CR)

39
Q

What should be absent in desired occlusion?

A
  • contact on anterior teeth
  • deflective interferences in eccentric movements
40
Q

How should you evaluate the cameo surface acrylic thickness?

A
  • observe intraorally and extraorally
  • use pressure indicator paste
  • make measurements
  • seek patient feedback
41
Q

What should you do for the patient at each appointment?

A

Educate

42
Q

What is the difference between an explanation and an excuse?

A

The time they are provided
- explain the limitations of dentures as mechanical substances for living tissues

43
Q

What is an explanation

A

Before the problem

44
Q

What is an excuse

A

After the problem

45
Q

What are instructions given to patients after denture delivery?

A
  • strange feeling of fullness in lips and cheeks for a few days
  • mandibular denture more difficult to use than maxillary CD
  • increased flow of saliva first few days
  • speaking approves with practice – read newspaper aloud everyday
  • expect sore spots during break in period
  • return to clinic for adjustements. Don’t adjust dentures at home
  • remove dentures at night and store in water
46
Q

What are instructions to give regarding chewing?

A
  • normal chewing takes about 2 months
  • begin with softer foods that are cut into smaller pieces
47
Q

How is control of the dentures accomplished by?

A

Manipulation with the tongue, lips, and cheeks

48
Q

How should you teach the patient to position the tip of their tongue?

A

Next to the lingual surfaces mandibular anterior teeth (have the patient say “e”)

49
Q

What should the patient use for extra security?

A

Denture adhesive powder AS NEEDED, during the first month

50
Q

What is care of the prosthesis?

A

Brushing (over a sink with water or a washcloth in it), soaking in a container, remove any adhesive

51
Q

What is care of the mouth?

A

Gingival massage, tongue brushing with a soft toothbrush
