Q

What is the sequence for using pressure indicating paste (PIP)?

A

Q

Why would gagging occur during the insertion appointment?

A
  • palate excessively thick

Q

What are the possible problems with phonetics during the insertion appointment?

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

Q

What are the sources of occlusion errors during the insertion appointment?

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%)
16
Q

What are the three parts of occlusal harmony?

A
  • patient comfort
  • efficient function (20% of natural)
  • preserve supporting tissues
17
Q

What percent of natural teeth function do dentures have?

A

20%

18
Q

Why should you hand occlude the completed dentures first before trying in the patient?

A

look for posterior flange contracts beyond tooth contacts

19
Q

Prior to making the record you should…

A

place two cotton rolls between the posterior teeth and have the patient bite down for 5 minutes (deprograms them)

20
Q

What are the simple steps to do a clinical remount?

A
  • make interocclusal record
  • remount dentures on articulator
  • refine occlusion on articulator
21
Q

Clinical remount and occlusal refinement are done before what?

A

final delivery of the dentures

22
Q

Occlusal errors will deform the supporting tissues & conceal the errors if what is postponed?

A

clinical remount and occlusal refinement

23
Q

What can interfere with paper markings during occlusal adjustment?

A

saliva

24
Q

What can be some problems that can occur with doing an intraoral occlusal adjustment?

A
  • resiliency of tissue allows dentures to move
  • misleading articulating paper marking
  • saliva interferes with markings
  • patient cooperation is a must
25
Q

What are the advantages of a clinical remount?

A
  • Reduces patient participation
  • Dentist sees better what to do
  • Stable working foundation; bases not shifting on resilient tissues.
  • Absence of saliva = more accurate marks with articulating paper.
  • Grinding may be done away from patient. This prevents patient
    objections to “mutilating my new teeth.”
26
Q

What is the desired occlusion for the insertion appointment?

A
  • Simultaneous contact of all posterior teeth in the retruded mandibular position (CR)
  • Absence of contact on anterior teeth
  • Absence of deflective interferences in eccentric movements
27
Q

What should you evaluate on the cameo surface acrylic?

A
  • thickness intraorally and extraorally
  • Use pressure indicator paste
  • Make measurements
  • Seek patient feedback
28
Q

What are some instructions you should give to the patient at the denture insertion appointment?

A
  • strange feeling of fullness in lips and cheeks
  • mandibular denture more difficult to use than maxillary CD
  • increased flow of saliva for the first few days
  • speaking improves practice
  • learning to chew takes about 2 months (begin with softer foods)
  • be patient
  • use denture adhesive powder for extra security
  • expect sore spots
  • remove dentures at night and store in water
  • return to clinic for adjustments
29
Q

How long does it take to learn how to chew properly with dentures?

A

2 months

30
Q

What is the oral hygiene needed for dentures?

A
  • Care of the prosthesis-brushing (over a sink with water or a washcloth in it), soaking in a container, remove any adhesive
  • Care of the mouth-gingival massage, tongue brushing with a soft toothbrush
