Guiding planes
1) Determine the path of insertion
2) Determine the path of removal
3) Assure predicatable clasp design
4) All of the above
Prosthodontics
Answer: 4
Guiding planes are flat, polished surfaces on the abutment teeth that guide the RPD into place. They are crucial for the predictable placement of retentive elements such as clasps and for ensuring that the forces are transmitted along the long axis of the teeth, minimizing horizontal movements. Additionally, they help in the overall stability and function of the denture.
When acrylic resin is packed in the sandy stage, it may result in
1) Open bite
2) Porosity
3) Increased strength
4) All of the above
Prosthodontics
Answer: 2
Packing acrylic resin in the sandy stage, which refers to a stage where the material is not fully polymerized and has a grainy texture, can lead to porosity in the final product. This occurs because the incomplete packing can trap air bubbles, resulting in a porous structure that compromises the strength and integrity of the restoration.

post and ball head, is the
1. Zest anchor
2. Ackermann joint
3. Doder attachment
4. Quinlivan attachment
Prosthodontics
Answer: 1
Explanation: The Zest anchor is a type of precision attachment used in dental prosthetics that provides a secure connection between the prosthesis and the remaining tooth structure. It utilizes a female component cemented into the root and a male component that fits into it, allowing for a stable and retentive connection. The other options do not describe this specific mechanism.<br />
