Candida

Question 3

Immediate dentures- 2 popular protocols

Answer 3

Conventional
Interim

Question 4

Conventional –

Answer 4

reline the immediate denture after
healing and ridge stable (6 months) ONE denture

relining/relifting is done

the denture is intended to be relined to serve as the long term prosthesis

Question 5

Interim / transitional –

Answer 5

aim is to use for short
period, then it is replaced by the definitive
prosthesis when healing is complete TWO dentures

new CD is made

after healing is completed, a second, new complete denture is to be fabricated as the long term prosthesis

Question 6

Immediate Complete Dentures
Advantages
(3)

Answer 6

Prevent patient embarrassment
Provide guide for optimal esthetics
Provide guide for OVD

maintenance of pt appearance
cicumoral support, muscle tone, OVD, jaw relationship, and face height can be maintained, the tongue will not spread out as a result of tooth loss
less postoperative pain as extraction sites are protected
easier to duplicate (if desired) the natural tooth shape and position
adaptation easier, speech and mastication are rarely compromised, and nutrition can be maintained
availability of tissue conditioning material
pt psychological and social well being is preserved

Question 7

Immediate Dentures
Disadvantages
(4)

Answer 7

Increased complexity – impressions, CJR
Lack of clinical evaluation of trial denture-anterior esthetics
Increased maintenance
Greater # visits = more cost

immediate dentures are a more challenging
the anterior ridge undercut (by the presence of remaining teeth) may interfere with the impression procedures
the presence of different numbers of remaining teeth in various locations frequently leads to recording incorrectly CR
no dentures tooth try in precludes knowing what the denture will actually look like on the day of insertion
more chair time, additional appointments, and therefore increased costs

Question 8

explanation to the pt concerning immediate dentures (4)

Answer 8

do not fit as well as normal CD
the pain of the extractions, in addition to the sore spots caused by the immediate denture, will make the first week or two after insertion difficult
difficult to eat and speak initially
the esthetics may be unpredictable bc an anterior try in is not possible

Question 19

Border-molded custom tray
Presence of teeth makes — more difficult

Answer 19

border molding

Question 20

Max. – Mand. registrations
(2)

Answer 20

Presence of anterior teeth may make OVD determination easier
Malposed, drifted, mobile teeth would make CJR registrations more
difficult
