Removable Partial Dentures

If several teeth are missing, or if adjacent teeth are not healthy enough to be abutments, a form of removable restorative device called a partial denture may be used. Partial dentures have (3) basic components in their design: (1) a framework that fits against the gums and other soft tissue of the mouth, (2) attachments connecting the framework to remaining natural teeth called clasps or rests, and (3) artificial, or prosthetic teeth mounted on the framework. Unlike bridges, partial dentures are not entirely supported by adjacent teeth but also by the gums and jawbones upon which the framework rests. A partial denture, whenever possible, is attached to the natural teeth to prevent loosening or shifting. Partial dentures can be designed to derive most of its support from the natural teeth, or some support from the teeth, but more support from gum and bone tissue, or all of its support from gum and bone tissue.
