Because of the great length of this clasp it must be designed with additional sup port, usually in the form of an auxiliary bracing arm. Which clasp is this?
1. Ring clasp
2, Combination clasp
3. Fish hook clasp
4. Multiple circlet clasp
Prosthodontics
Answer: 1
A ring clasp is a type of clasp used in removable partial dentures that encircles the abutment tooth. Due to its length and the potential for movement, it often requires additional support, typically provided by an auxiliary bracing arm, to ensure stability and retention of the prosthesis. This design helps distribute forces more evenly and prevents dislodgment during function.
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

A non-rigid or semi-rigid connector is indicated in some posterior bridges
1) When span of the bridge is long
2) When draw of the retainers cannot be achieved due to non-parallelism of the abutments
3) When the abutment teeth are parallel in short span of bridge
4) None of the above
Prosthodontics
Answer: 2
Non-rigid or semi-rigid connectors are used in dental bridges when there is a need to accommodate non-parallel abutments (option 2). This design allows for some movement between the components of the bridge, which can help in achieving a better fit and function when the abutments are not parallel.
The primary advantage of implant supported prosthesis is
1. decreased bulk of the prosthesis
2. improved phonetics
3. maintenance of alveolar bone
4. improved proprioception
Prosthodontics
Answer: 3
Explanation: Implant-supported prostheses have the advantage of maintaining
alveolar bone due to osseointegration. This helps preserve the natural bone
structure and reduces the risk of bone resorption that is common with
traditional complete dentures, which can lead to changes in the patient's facial
profile over time.
