The first step in surveying the casts for RPD is
1) Establishment of guiding planes
2) Establishment of undercuts for retention
3) Establishment of tooth contour for aesthetics
4) None of the above
Prosthodontics
Answer: 1
The initial step in surveying casts for an RPD is the establishment of guiding planes. These planes are essential for determining the path of insertion and removal of the denture, which in turn affects the overall stability and function of the prosthesis. Once the guiding planes are established, other steps such as identifying undercuts for retention and aesthetic considerations can be addressed.
