Q1: When border molding a mandibular custom tray that will be used for a final denture impression, the
distolingual extension is limited by the action of the:
A. superior constrictor muscle
B. masseter muscle
C. lateral pterygoid muscle
D. buccinator muscle
Answer: superior constrictor muscle
Q2: The primary reasons for obtaining the most extensive areal coverage for a mandibular complete denture are:
A. to increase the capacity of underlying structures to withstand the stress due to biting force and to improve
appearance
B. to provide balanced occlusion and to increase tongue space
C. to increase the capacity of the underlying structures to withstand the stress due to biting force and to
increase the effectiveness of the seal
D. to improve retention and to increase tongue space
Answer: to increase the capacity of the underlying structures to withstand the stress due to biting force
and to increase the effectiveness of the seal
Q3: A reline is indicated on any denture when the diagnostic information indicates that a reline will effectively
solve the patient's chief complaint—when the denture base adaptation is the major defect in the prosthesis.
A reline is contraindicated when there is excessive overclosure of the vertical dimension—a large decrease in
vertical dimension. In this case, new dentures are indicated at the proper vertical dimension.
A. both statements are true
B. both statements are false
C. the first statement is true, the second is false
D. the first statement is false, the second is true
Answer: both statements are true

C. 24 hours after delivery
D. 48 hours after delivery
Answer: 24 hours after delivery
Q5: Inadequate vertical dimension of occlusion may cause:
Q6: All of the following are true regarding the placement of maxillary central incisors in complete dentures
EXCEPT one. Which one is the EXCEPTION?
wt
A. long axes should be perpendicular to occlusal plane
B. arranged directly over the ridge
C. placement controls midline, speaking line and lip support arrange directly over the
ritge
D. are responsible for helping to make "F" and "V" sounds
Answer: arranged directly over the ridge
Q7: A patient who wears a complete maxillary denture complains of a burning sensation in the palatal area of
his/her mouth. This is indicative of too much pressure being exerted by the denture on the:
A. incisive foramen
B. palatal mucosa
C. hamular notch
D. posterior palatal seal
Answer: incisive foramen
incisive foramen
burning of the palatal area due to

incisive foramen
,Q8: The treatment plan for a patient indicates that both mandibular and maxillary immediate dentures are to be
fabricated. The ideal way to do this is:
A. fabricate the maxillary immediate denture first
B. fabricate the mandibular immediate denture first
C. fabricate the maxillary and mandibular immediate dentures at the same time
Answer: fabricate the maxillary and mandibular immediate dentures at the same time
Q9: The first step in the treatment of abused tissues in a patient with existing dentures is to:

B. reline the dentures X
C. educate the patient
D. excise the abused tissues
X
Answer: educate the patient ee the edition
Q10: The most important benefit of an overdenture (root-retained denture) is:
A. the psychological comfort of avoiding the loss of all teeth
B. the continuous functional feedback for the neuromuscular system from proprioceptors in the periodontal
membrane
C. the preservation of the alveolar ridge
D. the improved support and stability for the denture
E. the increased retention of the denture
Answer: the preservation of the alveolar ridge
Q11: Which sounds help determine the labiolingual position of the anterior teeth?
A. linguoalveolar sounds or sibilants (such as s, z, sh, and ch)
B. fricatives or labiodental sounds (such as f, v, or ph)
C. the b, p, and m sounds
2
D. linguodental sounds (such as this, that, or those)
Answer: linguodental sounds (such as this, that, or those)
linguodental sound this that those

, Q12: Whistling in a speaking denture patient may be caused when:
A. vertical overlap is not enough
B. the area palatal to the incisors is improperly contoured
C. horizontal overlap is too much
D. all of the above
Answer: all of the above
Q13: A patient has worn a complete maxillary denture for 8 years against mandibular anterior teeth (the
remainder of the mandibular teeth are missing). She complains of looseness of the denture. Examination of the
mouth shows an excessive amount of hyperplastic tissue at the anterior part of the maxillary ridge. The maxillary
denture teeth do not show below the upper lip. Radiographs show poor bone structure in the anterior part of the
maxillae. The principal cause of difficulty with her maxillary denture is:
A. fibrous tuberosities
B. too great a vertical dimension of occlusion
C. a lack of posterior occlusion
D. the maxillary denture teeth that were used are too short
Answer: a lack of posterior occlusion
a lack ofgo.tw
Q14: The primary indicator of the accuracy of border molding is:
y
A. adequate coverage of tray borders with the material used for border molding
B. contours of the periphery similar to the final form of the denture
C. stability and lack of displacement of the tray in the mouth
D. uniformly thick borders of the periphery
Answer: stability and lack of displacement of the tray in the mouth
Q15: The ultimate support for a maxillary denture is the bone of the two maxillae and the palatine bone.
The palatal rugae are a primary support area as well.
A. both statements are true
B. both statements are false
C. the first statement is true, the second is false
D. the first statement is false, the second is true
Answer: the first statement is true, the second is false
