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

, 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
