Which of the following is likely to occur if the VDO is increased in a
complete denture patient?
1. Loss of lip fullness
2. Decreased nose-chin distance
3. Limited tongue space
4. Clicking of teeth
Prosthodontics
Answer: 4
Explanation: Increasing the VDO can lead to increased vertical clearance between
the teeth, potentially causing them to click during function. This can also
affect the patient's speech and the stability of the denture. It is important to
carefully evaluate and adjust the VDO to minimize these issues.

The main purpose of covering as much area as possible within functional limits by impression is to
1. Distribute the occlusal stresses and increase the peripheral seal
2. Increase the bulk of CD which helps to seat the denture
3. To increase the bulk of CD to prevent its fracture
4. All of the above
Prosthodontics
Answer: 1
The main purpose of covering as much area as possible within functional limits by impression is to distribute the occlusal stresses and increase the peripheral seal.
A single bilateral edentulous area located anterior to the remaining natural teeth is classified as Kennedy-Apple- gate
1. Class I
2. Class II
3. Class III
4. Class IV
Prosthodontics
Answer: 4

edentulous area that crosses the midline and is located anterior to the
remaining natural teeth. It is the only class that is purely anterior.
The occlusal plane for the complete denture patient is determined by
1. The face bow device which determines the occlusal plane
2. The position of the upper first molar
3. The height of the retromolar pad and anterior aesthetic height
4. None of the above
The occlusal plane for the complete denture patient is determined by the height of the retromolar pad and anterior aesthetic height.

Which of the following is least likely to occur when record bases are formed
from self-curing resins, on the master
cast of an edentulous patient without blocking out the undercuts ?
1 The borders will not be accurately reproduced
2 Record bases will exhibit instability in the patients mouth
3 The casts may be abraded when removing the record bases
4 Record bases may break when removing from the casts
Prosthodontics
Answer: 1
Explanation: When record bases are formed from self-curing
resins without blocking out undercuts, the most likely issues are instability in
the mouth, abrasion of the casts, and potential breakage of the record bases
upon removal. However, the borders of the record bases are typically
well-defined and can be accurately reproduced even if undercuts are not blocked
out. Therefore, option 1 is the least likely occurrence.
