Fixed Partial Dentures

Fixed Partial Denture is a prosthesis that replaces some teeth in a partially dentate arch, and can not be removed from the mouth nor replaced at will. Fixed Partial Denture, also known as FPD, replaces some missing teeth, for health, function and esthetic purposes.

Fixed Partial Denture can be classified in many ways. It can be based on its support:
1. Tooth Supported Fixed Partial Dentures.
2. Implant Supported Fixed Partial Dentures.

In Tooth Supported Fixed Partial Dentures, the natural dentition are used for the FPD abutments.

Dental Implants are used as abutments in Implant Supported Fixed Partial Dentures.

It can also be classified based on how it’s being supported:
1. Fixed-fixed Partial Denture.
2. Fixed-movable Partial Denture.
3. Cantilever Fixed Partial Denture.

Fixed movable partial denture is sometimes called as fixed free partial denture. It is a partial denture where the pontic is rigidly supported on one side, usually the distal end by one or more abutment teeth. On the other side, the abutment will contain a precision abutment, a stress breaking device.

Fixed-fixed Partial Denture, also known as fixed-fixed dental bridge, is a design of fixed partial prosthesis that has a rigid connector at both ends of the pontic.

Cantilever Fixed Partial Denture is a design of bridge where the artificial tooth is supported on one side only by one or more abutment teeth.

Fixed Partial Denture can also be classified on how it’s retained.
1. Cement Retained Fixed Partial Denture.
2. Screw Retained Fixed Partial Denture.

In Cement Retained Fixed Partial Denture, the prosthesis, crown, or crown and bridge is cemented to the abutments.

Screw Retained Fixed Partial Denture utilizes screws to secure the FPD to an implant or implants, or to a crown in certain cases like segmented bridge and screw assembled prosthesis.

Another classification of Fixed Partial Denture is based on its use:
1. Provisional Fixed Partial Denture.
2. Final Fixed Partial Denture.

Provisional Fixed Partial Denture, also named as Temporary Fixed Partial Denture, is primarily used as a protection of the abutments after tooth preparation and before the installation of the final FPD. It is also used to prevent physiologic movement of the abutments while waiting for the final FPD. Is is usually fabricated using acrylic resin.

Final Fixed Partial Denture, is the definitive prosthesis. It is usually made with ceramics or metal.

Pictures of Fixed Partial Dentures

Segmented Fixed Partial Denture

The photo above shows a Segmented Fixed Partial Denture. The first segment, is a Fixed-fixed Partial Denture. The second segment is a Fixed-movable Partial Denture.

Cantilever Fixed Partial Denture

The photo above shows a Cantilever Fixed Partial Denture. It replaces the missing lateral incisor. The abutment used is a premolar.
