MDS PREP
The following aslo serves in guiding path of insertion and path of removal along with guiding planes
1) Minor connector
2) Occlusal rest
3) Major connector
4) Clasps
Prosthodontics
Answer: 1
While guiding planes are the primary elements that dictate the path of insertion and removal, the minor connector also plays a role. The minor connector helps in the overall stability and retention of the RPD by linking the major connector to the abutment tooth and distributing the forces more evenly across the denture base. However, its primary function is not to guide the path of insertion and removal as much as it is to provide additional support and strength to the RPD.
Which of the following is most likely to cause complete obturation of pulp space
1. A deep restoration without base
2. A deep blow to tooth where tooth was injured and not devitalised
3. Normal calcification process in middle age
4. A deep carious lesion
Prosthodontics
Answer: 2
Which of the following is most likely to cause complete obturation of pulp space: a deep blow to the tooth where the tooth was injured and not devitalized.
A complete denture wearing patient complains of tingling sensation in the lower premolar region. The ridges are resorbed. The most possible explanation
1. Pressure on the mucosa due to ridge resorption
2. Pressure on the mental foramen due to ridge resorption
3. Occlusal discrepancies due to ridge resorption
4. All of the above
Prosthodontics
Answer: 2
A complete denture wearing patient complains of tingling sensation in the lower premolar region. The ridges are resorbed. The most possible explanation is pressure on the mental foramen due to ridge resorption.
Selective grinding for equilibrating complete dentures is best accomplished after processing when the dentures are
1) Rearticulated using original jaw relation record
2) Rearticulated with a new series of jaw relation
3) Equilibrated in the patient"s mouth
4) None of the above
Prosthodontics
Answer: 2
Selective grinding is a technique used to adjust the occlusion of complete dentures. It is best performed after the dentures have been processed and rearticulated with a new series of jaw relations to ensure that the occlusion is accurate and reflects the patient's current jaw relationship. This allows for more precise adjustments to be made, as the original records may not accurately represent the current occlusal relationship after processing.
One of the following rules explains about the grinding of certain cusps to produce balance in lateral movements
1) Ante"s rule
2) Bull rule
3) Wolf"s rule
4) Cieszynski"s rule
Prosthodontics
Answer: 2
The Bull rule pertains to the concept of occlusal balance during lateral
movements in dentistry. It suggests that certain cusps may need to be adjusted
or ground to achieve a balanced occlusion, particularly in the context of
removable prosthodontics or fixed restorations.
Ante's rule (option 1) relates to the relationship between the anterior and
posterior teeth in occlusion.
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.
Occlusal rims for making the jaw relations aids in all of the following except
1. Determination of the centric relation
2. Determinatin of the overjet
3. Orientation of plane of occlusion or Camper"s line
4. Estimation of freeway space
Prosthodontics
Answer: 4
Occlusal rims for making the jaw relations aid in all of the following except estimation of freeway space.
Examination of patient revealed hyperplastic tuberosity touching the retromolar pad in mandibular rest position. You would like
1. Deepen the retromolar pad before construction of the CD
2. Reduce the tuberosity before constructing complete dentures
3. Both of the above
4. None of the above
Prosthodontics
Answer: 2
Examination of the patient revealed hyperplastic tuberosity touching the retromolar pad in the mandibular rest position. You would like to reduce the tuberosity before constructing complete dentures.
