The most common reason why hyperplastic tissue is removed or reduced during construction of a complete denture because
1. It interferes with the arrangement of the teeth
2. It is unaesthetic to construct a denture on a hyperplastic tissue
3. It interferes with the stability of the denture
4. All of the above
Prosthodontics
Answer: 3
The most common reason why hyperplastic tissue is removed or reduced during the construction of a complete denture is that it interferes with the stability of the denture.
Which of the following is true regarding immediate complete dentures?
1. Dentures should be relined or remade in 6-12 months
2. The patient should not wear the dentures for the first 24 hours after
extraction
3. Anterior try in should be done
4. Teeth should always be placed in the same position as natural teeth
Prosthodontics
Answer: 1
Explanation: Immediate complete dentures often require relining or remaking due
to the significant bone and tissue changes that occur during the initial healing
phase after tooth extraction. The reline helps to adapt the denture to the new
contours of the alveolar ridge, providing a more stable and comfortable fit.
Postdam area serves mainly to
1. Prevent ingress of food and saliva beneath denture base
2. Preventing lifting away of denture during incising
3. Stabilize the denture
4. Both A and B

Answer: 4
Postdam area serves mainly to prevent ingress of food and saliva beneath the denture base.

4) None of the above
Prosthodontics Answer: 2
The half moon shape is ideal for canine rests as it provides adequate support and stability for the removable partial denture.

Acrylic resin posterior teeth along with porcelain anterior teeth should not be
used in complete dentures because
1. it produces resorption of posterior residual ridge as acrylic teeth wear
2 they cause resorption of anterior residual ridge
3. the combination produces harmful stress concentrations
4 This combination can be used
Prosthodontics
Answer: 2
Explanation: The combination of acrylic resin posterior teeth
and porcelain anterior teeth can lead to differential wear and stress
concentrations, which may cause resorption of the anterior residual ridge.
Porcelain teeth are harder and can create more stress on the underlying bone
compared to acrylic teeth, leading to potential resorption. Therefore, option 2
is the correct answer, as it highlights the negative impact on the anterior
ridge.
