What is a key reason why RPD is preferred over FPD?

RPD, or removable partial dentures, are often considered more hygienic than fixed partial dentures (FPD) due to their design and functionality. With RPDs, patients can remove the appliance, allowing for better access to their natural teeth and gums, making it easier to maintain proper oral hygiene. This can significantly reduce the risk of plaque accumulation and periodontal disease, which can be more challenging to manage with a fixed appliance that remains in place.

Patients using FPDs may find it more difficult to clean around the fixed components, as these prostheses do not allow for easy access to the underlying tissues. Therefore, while both options have their own benefits and potential drawbacks, the ability to remove an RPD facilitates better daily hygiene practices, making it a preferred choice from a health perspective.

Other considerations, like cost, maintenance, and aesthetics, play a role in choosing between RPD and FPD, but the ability to remove the RPD for cleaning is a significant factor in promoting better oral hygiene.
