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

Answer: 4
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 purpose of plane of orientation is
1. To serve as a guide in establishing occlusal plane
2. To aid in measuring height and length of posterior teeth
3. Both A and B
4. None of the above

Answer: 1
The purpose of the plane of orientation is to serve as a guide in establishing the occlusal plane.
FPDs are generally contraindicated and the missing teeth replaced with a RPD,
in patients less than
1. 17 years old
2. 10 years old
3. 30 years old
4. 46 years old
Prosthodontics
Answer: 2
FPDs are generally contraindicated for several reasons:
Growth and Development: Children are still in their
growth phase, and their jaws and teeth are developing. Placing a fixed
prosthesis can interfere with normal growth patterns and may require
adjustments or replacements as the child grows.
Eruption of Permanent Teeth: In younger patients,
especially those under 10, many of the permanent teeth have not yet erupted.
Using FPDs in this age group can complicate future dental treatments, as the
position of the teeth may change with the eruption of permanent teeth.
What does the term "relief" refer to in the context of dental
surveying?
1) The addition of material to the denture
2) The measurement of tooth height
3) The process of cleaning the cast
4) The reduction or elimination of undesirable pressure from specific areas
Prosthodontics
Answer: 4
Relief is important in denture design as it helps to prevent pressure points that could cause discomfort or tissue damage.
