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.
