MDS PREP

When there is a prematurity in centric occlusion but not in eccentric or other movements, then reduce
1. Cusps of opposing teeth
2. Mesiodistal position of teeth
3. Opposing fossa or marginal ridge
4. None of the above

Prosthodontics Answer: 3

The amount of reduction required for a tooth for all metal crown restoration is
1) So that there is proper clearance between the teeth
2) So that the tooth architecture interferes with the arch of rotation
3) So that the tooth architecture does not interfere with the arch of rotation
4) At least 2 mm on all the surfaces

Prosthodontics Answer: 2

The pontic design of choice in the appearance zone of maxillary and mandibular bridge
1) Hygienic
2) Modified ridge lap
3) Saddle
4) Conical

Prosthodontics Answer: 2

In designing the occlusal rest seat, the floor of the rest seat should be inclined towards the
1) Buccal surface
2) Centre of the tooth
3) Lingual surface
4) Marginal ridge

Prosthodontics Answer: 2

Which type of RPD definitely requires an indirect retainer?
1) Class I, II RPD
2) Class II, IV RPD
3) Class I and IV RPD
4) Class III and IV RPD

Prosthodontics Answer: 1

A ledge is created on the lingual surface of the full cast crown to accommodate the lingual clasp arm. The greatest advantage is that it provides for
1) Appropriate contact
2) Appropriate undercut
3) Survey line
4) Guiding plane

Prosthodontics Answer: 4

The posterior palatel seal for a maxillary complete denture
1) Is placed immediately posterior to the vibrating line
2) Is placed immediately anterior to the vibrating line
3) Is not necessary if a metal base is made
4) Will vary in outline and depth according to the palatal form

Prosthodontics Answer: 4

An abutment tooth exhibiting an unfavourable survey line should
1) Be restored
2) Have unfavourable contours improved
3) Be by-passed in the framework design
4) Receive only a rest and not to be clasped
