Terms used in fixed partial dentures

Abutment is a tooth to which a bridge is attanched.

Retainer is a crown or other restoration that is cemented to the abutment. The terms retainer and abutment should not be confused or used interchangeably.

Pontic is an artificial tooth as part of a bridge.

Span is the space between natural teeth that is to be filled by the bridge.

Saddle is the area of the edentulous ridge over which the pontic will lie.

Pier is an abutment tooth standing between and supporting two pontics, each pontic being attached to a further abutment tooth.
