hello hanan,
You had put across a couple of questions in prostho, have those been answered? Do you still have those questions?
thanks
Hi!
Here are my "famous"
😉 prostho questions. nobody wants to share
😛
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.
