Which of the following is not desirable in complete denture occlusion
1 Minimum occlusal contact areas for reduced pressure in comminuting food
2 Functional lever balance by favorable tooth to ridge crest position
3 Balanced occlusal contacts bilaterally for all eccentric movements
4 Anterior incisal contacts during all posterior masticatory functions and para
function
Prosthodontics
Answer: 4
Explanation: Anterior incisal contacts during posterior
masticatory functions are not desirable because they can lead to instability and
improper function of the complete denture. Ideally, posterior teeth should
provide the primary occlusal contacts during chewing, while anterior teeth
should not interfere with these functions. This helps maintain a balanced
occlusion and prevents excessive wear or damage to the denture.
Before construction of the complete denture, patient"s natural dentition is evaluated because it helps in
1. Establishing vertical dimension
2. Arranging the teeth in balanced occlusion
3. Selection of form, shape, and size of the artificial teeth
4. All of the above
Prosthodontics
Answer: 3
Before construction of the complete denture, the patient's natural dentition is evaluated because it helps in all of the above: establishing vertical dimension, arranging the teeth in balanced occlusion, selection of form, shape, and size of the artificial teeth.
The primary function of the compensating curve, incorporated in complete
dentures, is to provide
1 stability in centric relation
2. balanced occlusion during lateral movements of the mandible
3 an esthetically pleasing denture
4. balancing occlusal contacts during protrusive movements
Prosthodontics
Answer: 4
Explanation: The compensating curve is designed to ensure
that occlusal contacts are balanced during protrusive movements, which is
essential for maintaining stability and function of the complete denture. This
curve helps to distribute occlusal forces evenly and prevents tipping or
dislodgment of the denture during functional movements. The other options do not
accurately reflect the primary purpose of the compensating curve.
The most important advantage of incomplete dentures, is the
1 low cost of their fabrication
2 less time required for their construction
3 preservation of the health of the TM joints
4 preservation o the maximum amount of ridge bulk with minimum of trauma and
swelling
Prosthodontics
Answer: 4
Centric jaw relation is made
1. At established vertical dimension
2. Before the vertical dimension is established
3. At a greater level than established vertical dimension
4. No relative to the vertical dimension
Prosthodontics
Answer: 1
Centric jaw relation is made at established vertical dimension.
The mean denture bearing area in the edentulous mandible is approximately
1. 12.25 cm square
2. 16.25 cm square
3. 18.12 cm square
4. 20.25 cm square
Prosthodontics
Answer: 1
The mean denture bearing area in the edentulous mandible is approximately 12.25 cm square.
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.

4. Their position is not fixed
Prosthodontics
Answer: 2
Fovea palatine are situated in the soft palate.
