Isolated recession on a labially prominent upper canine is noted. Examination revealed absence of keratinised gingiva in that area and the vestibule is shallow. The best mehtod to create zone of attached gingiva in this case
1. Free pedicle graft
2. Lateral sliding graft
3. Apically positioned flap
4. Coronally displaced flap

The pattern of mandibular movement of complete denture patients and those with natural teeth are
1. Same
2. Mandibular movement in complete denture patients are completely different
3. Mandibular movement is slow in CD patients
4. None of the above
Prosthodontics
Answer: 1
The pattern of mandibular movement of complete denture patients and those with natural teeth are the same.
If the clasp assembly is not being placed on a tooth adjacent to an edentulous
area, the minor connector must
be positioned
1. in the embrasure between two teeth
2. on the lingual surface of the tooth distal to the edentulous space
3. on the lingual surface of the tooth mesial to the edentulous space
4. on any tooth with a convex lingual surface
Prosthodontics
Answer: 1
Explanation: The minor connector should be positioned in the embrasure between
two teeth to provide adequate support and stability for the clasp assembly. This
positioning helps distribute forces evenly and maintains the integrity of the
prosthesis. The other options do not provide the same level of support.
Retromolar area should be covered in CD or distal extension RPD in order to
1. Provide the better marginal seal
2. To slow down the rate of resorption of alveolar bone in posterior area
3. Derive support from the underlying bone which is resistant to resorption
4. All of the above
Prosthodontics
Answer: 4
Retromolar area should be covered in CD or distal extension RPD in order to derive support from the underlying bone which is resistant to resorption.
What is the purpose of using undercut gauges in dental surveying?
1) To identify the amount of retentive undercut
2) To measure the size of the cast
3) To contour wax patterns
4) To clean the surveyor
Prosthodontics
Answer: 1
Undercut gauges are specifically designed to measure the amount of retentive undercut available on the cast.
Oral examination of an edentulous patient should include digital palpation. Why?
1. The arch form is more accurately evaluated
2. Undercut areas may be better evaluated
3. The ridge relationship may be better evaluated
4. None of the above
Prosthodontics
Answer: 2
Oral examination of an edentulous patient should include digital palpation to evaluate undercut areas better.
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.
