Hi!
Let's share some questions about complete dentures. here are my sugesstions:

Which of the following structures affects the
thickness of the flange of a maxillary complete
denture?
A. Malar process.
B. Coronoid process.
C. Mylohyoid ridge.
D. Zygomatic process.
E. Genial tubercle.

During the fabrication of new complete dentures,
which of the following can be modified to achieve
the desired occlusion?
1. The compensating curve.
2. The orientation of the occlusal plane.
3. The cusp inclination.
4. The condylar inclination.
A. (1) (2) (3)
B. (1) and (3)
C. (2) and (4)
D. (4) only
E. All of the above.

A patient with complete dentures complains of
clicking. The most common causes are
A. reduced vertical dimension and
improperly balanced occlusion.
B. excessive vertical dimension and poor
retention.

C. use of too large a posterior tooth and too
little horizontal overlap.
D. improper relation of teeth to the ridge and
excessive anterior vertical overlap.


A maxillary complete denture exhibits more
retention and stability than a mandibular one
because it
1. covers a greater area.
2. incorporates a posterior palatal seal.
3. is not subject to as much muscular
displacement.
4. is completely surrounded by soft tissue.
A. (1) (2) (3)
B. (1) and (3)
C. (2) and (4)
D. (4) only
E. All of the above.

In patients wearing complete dentures, the most
frequent cause of tooth contact (clicking) during
speaking is
A. nervous tension.
B. incorrect centric relation position.
C. excessive occlusal vertical dimension.
D. lack of vertical overlap.
E. unbalanced occlusion.

To improve denture stability, mandibular molar
teeth should normally be placed
A. over the crest of the mandibular ridge.
B. buccal to the crest of the mandibular
ridge.

C. over the buccal shelf area.
D. lingual to the crest of the mandibular
ridge.

A patient wearing complete dentures complains of
tingling and numbness in the lower lip bilaterally.
This is often an indication of
A. allergy to denture base material.
B. impingement of denture on mandibular
nerve.
C. defective occlusal contacts.
D. impingement of denture upon mental
nerve.

E. neoplastic invasion of the inferior
mandibular nerve.

Following the insertion of complete dentures,
a generalized soreness over the entire
mandibular alveolar ridge can be caused by
A. Inadequate interocclusal distance.
B. impingement on the buccal frenum.
C. high muscle attachments.
D. excess border thickness.

In an edentulous maxilla, the direction of
resorption of the alveolar ridge is
A. upward and palatally.
B. upward and facially.
C. uniform in all directions.
D. upward only.


Upon examination of an edentulous patient, it
is observed that the tuberosities contact the
retromolar pads at the correct occlusal vertical
dimension. The treatment of choice is to
A. reduce the retromolar pads surgically
to provide the necessary clearance.
B. reduce the tuberosities surgically to
provide the necessary clearance.
C. construct new dentures at an
increased occlusal vertical dimension
to gain the necessary clearance.
D. proceed with construction of the
denture and reduce the posterior
extension of the mandibular denture
to eliminate interferences.


Vestibuloplasty is a preprosthetic surgical
procedure used to
A. facilitate reliable impression making.
B. provide adequate posterior inter-arch
space.
C. allow placement of teeth over the
residual ridge.
D. increase the supporting surface area

In complete dentures, the external oblique line
is used as a guide for the
A. position of the posterior teeth.
B. height of the occlusal plane.
C. termination of the buccal flange.
D. termination of the lingual flange.

Extreme resorption of an edentulous mandible
can bring the alveolar ridge to the level of the
attachment of the
A. buccinator, styloglossus and
geniohyoid muscles.
B. mylohyoid, buccinator and
styloglossus muscles.
C. superior constrictor, mylohyoid and
buccinator muscles.

D. mylohyoid, buccinator and
genioglossus muscles.
 
hi!one of the question says that if at an established vertical dimension of occlusion...max tuberosity inteferes with retromolar pad area....the treatment modality is to limit the posterior extension of the mandibular denture to avoid that interference......but dont u think if we decrese the area coverage of mandibular denture.that will result into decresed retention ,so why cannot we reduce the tuberosities surgically to avoid it.......
can anyone plzlerify my doubt......thanks.gag
 
Hi!
nobody intersted in complete dentistry questions?
Come on! please do post your suggestions...

Please somebody explain....I have the same doubt.
 
Excessive vertical dimension may
result in
1 poor denture retention.
2 Drooping of the corners of the
mouth.
3 Creases and wrinkles around the lips.
4 Trauma to the underlying supporting
tissues.👍

The distal palatal termination of the
maxillary complete denture base is
dictated by the
1 tuberosity.
2 fovea palatinae.
3 Maxillary tori.
4 Vibrating line.👍
5 Posterior palatal seal.

Placement of maxillary anterior teeth
in complete dentures too far
Superiorly and anteriorly might
result in difficulty in pronouncing
1 "f" and "v" sounds. 👍
2 "d" and "t" sounds.
3 "s" and "th" sounds.
4 Most vowels.

Treatment of choice for a patient with a
maxillary complete denture with severe
bilateral tuberosity undercuts is to
1 remove both tuberosity undercuts.
2 Reduce the tissue bilaterally.
3 Reduce the tissue on one side only, if
possible. 👍
4 None of the above. No treatment is
necessary


The error that most frequently contributes
to poor esthetics of dentures is the
practice of placing maxillary anterior teeth
1 following the smile line.
2 Too far below the lip line.
3 Directly over the edentulous ridge.👍
4 Too far to the facial of the edentulous
ridge.
5 Too far to the lingual of the edentulous
ridge.

correct me please if I am wrong.
