What is the most important factor in RDP design?

In the context of removable partial denture (RDP) design, choosing a clasp system that causes the least harm is crucial because it directly affects the health of the abutment teeth and the overall stability of the prosthesis. The clasp must provide adequate retention while minimizing any potential negative impact on dental structures. An optimal clasp system maintains the health of the gums and underlying bone, preventing issues such as root resorption or periodontal disease.

While the type of metal used, aesthetics, and the design of minor connectors all play significant roles in RDP design, they do not address the fundamental requirement of ensuring that the prosthesis functions effectively without compromising the integrity of the abutment teeth. Retention mechanisms that minimize harm contribute to both patient comfort and the longevity of the prosthesis, making this factor a primary concern in the design process.
