Before registering face bow transfer, it is necessary to determine
1. Physiological rest space
2. Incisal guidance
3. Centric relation and centric occlusion
4. Terminal hinge axis opening
Prosthodontics
Answer: 4
Before registering face bow transfer, it is necessary to determine terminal hinge axis opening.
The most desirable temporary record base for an edentulous patient is the one
made from
1. shellac, reinforced with a 12 gauge stainless steel wire
2 cold cure resin by the sprinkle on method
3. polystyrene in a thermal vacuum machine
4. cold cure resin by the noncompression dough technique
Prosthodontics
Answer: 2
Explanation: The cold cure resin by the sprinkle-on method
provides a stable and accurate temporary record base for edentulous patients.
This method allows for better adaptation to the oral tissues and ensures a more
reliable fit during the recording of jaw relations.
Effective alternation in the abutment with short clinical crowns for proper clasp retention can be achieved by
1) Proper guiding planes
2) Restoring with full crown
3) Altering the height of contour
4) All of the above
Prosthodontics
Answer: 2
When dealing with short clinical crowns in RPD abutment teeth, restoring the teeth with full crowns can provide additional retentive surfaces and support for the clasp. This can be particularly useful when the available undercuts are limited, thereby enhancing the overall stability and retention of the prosthesis.
Closest speaking space in normal jaw relations is approximately
1. 0 to 1.5 mm
2. 1.5 to 3 mm
3. 3 to 6 mm
4. 6 to 9 mm
Prosthodontics
Answer: 2
Closest speaking space in normal jaw relations is approximately 1.5 to 3 mm.

1. Condylar inclinations
2. Compensating curve
3. Incisal guidance
4. Cuspal inclinations
Prosthodontics
Answer: 3
Of the four factors affecting balanced occlusion in complete dentures, which of the following can be altered by only a slight amount: incisal guidance.
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.
