There are many who say that the smartest man to have ever lived was Albert Einstein. He is certainly one of the most famous of the great thinkers and his intellect contributed massively to the advancement of science.
A partial is a dental prosthetic (artificial tooth or teeth) that can be removed from the mouth somewhat like an orthodontic retainer. A bridge, on the other hand, is a dental prosthetic that's permanently anchored inside the mouth. Partials are sometimes referred to as RPDs (removable partial dentures). They're often selected as an inexpensive option over a bridge or dental implant for replacing lost teeth. Most partials work in a similar way: Artificial teeth are placed on a molded base to which metal clasps are added.
A removable partial denture is also known as a removable dental bridge. A removable dental bridge fills the gap between two healthy teeth and consists of replacement teeth attached to a gum-colored plastic base. Removable partial dentures are connected by a metal framework that helps keep them in place.
