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.
It is usually easier to record the vertical dimension for RPD patients as
1. there are usually some teeth remaining
2. the patients are usually young with neuromuscular control
3. pre-extraction records are usually available
4. the physiologic rest position is usually unaltered
Prosthodontics
Answer: 1
Explanation: The vertical dimension of occlusion (VDO) is easier to establish in patients with removable partial dentures (RPDs) because they typically have some natural teeth remaining. These teeth provide reference points for occlusal relationships and help in determining the appropriate vertical dimension. The presence of remaining teeth allows for better tactile feedback and aids in achieving a more accurate and functional occlusion. The other options, while they may have some relevance, do not directly contribute to the ease of recording VDO as effectively as the presence of remaining teeth.
Which survey line is placed in the occlusal third in both near and
far zones?
1) Medium survey line
2) Low survey line
3) High survey line
4) Diagonal survey line
Prosthodontics
Answer: 3
The high survey line is characterized by being positioned in the occlusal third of the tooth in both the near and far zones, which is important for determining the contour of the tooth.
While taking impression of flabby fibrous tissue on maxillary ridge for complete denture care is taken to
1. Use a tray with spacer
2. Not maintain intimate contact with tissues
3. Use a close fitting tray
4. Follow normal procedures
Prosthodontics
Answer: 1
While taking an impression of flabby fibrous tissue on the maxillary ridge for complete denture, care is taken to use a tray with spacer.
An overextended mandibular denture will be dislodged as a result of function of
1. Masseter
2. Temporalis
3. Buccinator
4. Lateral pterygoid
Prosthodontics
Answer: 1
An overextended mandibular denture will be dislodged as a result of the function of masseter.
Encroachment into the freeway space results in
1. Irreversible bone changes
2. Irreversible soft tissue inflammation
3. Both soft tissue and bone changes which are reversible
4. Reversible soft tissue inflammation and irreversible bone changes
Prosthodontics
Answer: 4
Encroachment into the freeway space results in reversible soft tissue inflammation and irreversible bone changes.
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 primary advantage of an immediate denture is that the patients can continue with their social activities without any embarrassment.
The direction of the resorption of the maxillary ridge
1. Downwards and buccally
2. Upwards and lingually
3. Downwards and lingually
4. Upwards and buccally
Prosthodontics
Answer: 2
The direction of the resorption of the maxillary ridge is upwards and lingually.
