What is the difference between a removable partial denture designed with a bounded saddle versus a free-end saddle, and how does this affect support?

There is no clinical difference between bounded and free-end saddles A bounded saddle has abutment teeth on both sides of the edentulous span (tooth-supported); a free-end saddle extends distally with no posterior abutment (mucosa-supported distally), requiring careful consideration of support, retention, and path of insertion to manage differential tissue support A free-end saddle is always contraindicated in partial denture design Bounded saddles require implants for support; free-end saddles do not

Correct Answer:

A bounded saddle has abutment teeth on both sides of the edentulous span (tooth-supported); a free-end saddle extends distally with no posterior abutment (mucosa-supported distally), requiring careful consideration of support, retention, and path of insertion to manage differential tissue support
