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.
To allow space for the dentures, most tuberosity reduction require
1. Only soft fibrous tissue removal
2. Large part of the bone to be removed
3. Removal of bone always
4. Reduction of bone always on both sides
Prosthodontics
Answer: 1
To allow space for the dentures, most tuberosity reduction requires only soft fibrous tissue removal.
What does the term "block out" refer to in the context of dental
surveying?
1) The removal of teeth
2) The elimination of undesirable undercut on the master cast
3) The process of cleaning the cast
4) The application of wax to the cast
Prosthodontics
Answer: 2
Block out is the process of eliminating
undesirable undercuts on the master cast before duplication, ensuring a better
fit for the prosthesis.
The primary advantage of an immediate denture is that
1. centric relation (CR) is easier to record
2. less ridge resorption occurs as the ridges are subjected to early function
3. the patients can continue with their social activities without any
embarrassment
4. artificial teeth can be set in identical Positions as those occupied by the
natural teeth
Prosthodontics
Answer: 3
The patients can continue with their social activities without any
embarrassment is indeed a significant advantage of immediate dentures. The
immediate placement of a denture allows individuals to maintain their confidence
and appearance, which can be crucial for their psychological well-being and
social interactions. Patients do not have to go through a toothless phase, which
can be traumatic and affect their self-esteem. This statement is the most
relevant to the immediate benefit of having an immediate denture.
Main advantage of RPD over fixed bridge in replacing bilateral lost teeth
1) Cross arch stabilisation
2) Aesthetics
3) Less expensive
4) Comfort of the patient
Prosthodontics
Answer: 1
Cross Arch Stabilization: RPDs provide cross arch stabilization by distributing the forces of mastication more evenly across the remaining natural teeth and the edentulous (toothless) regions of the arches. This is particularly beneficial when there are missing teeth on both sides of the mouth. An RPD connects to the teeth on both sides of the mouth, which helps maintain the alignment and stability of the remaining dentition. In contrast, a fixed bridge typically relies on the adjacent natural teeth for support, which can result in increased load and stress on these abutment teeth. This additional stress can potentially lead to issues such as tooth decay, root fracture, or periodontal disease if not managed properly.
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
Kennedy Class IV is characterized by a single
edentulous area that crosses the midline and is located anterior to the
remaining natural teeth. It is the only class that is purely anterior.
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.
