Porcelain, resins and porcelain fused to metal are the classical and most often used materials in fixed partial prosthodontics. The teeth and presently – dental implants, used as support gives us very adequate prosthodontic rehabilitation.

Extracoronal Attachment is a type of precision attachment which involves two parts. The first half has a ball joint cantilevered from the abutment unit. The second part, is housed within the one piece casting framework. The attachment may involve a spring or an O ring or a similar component.

Veneer is a thin tooth shaped glass ceramics facing luted to the underlying tooth structure using a filled resin. Veneers, also known as laminates, are usually done for esthetic purposes – to mask discoloration and to correct malformations of tooth shape, spacing and tooth chipping.

Temporary Removable Partial Dental Prosthesis is incorporated into a total denture treatment plan for various reasons. Temporary removable partial dentures are typically made of acrylic resin with wire retention and may include other components to provide support.
Sometimes replacement of missing teeth is necessary for short period of time such as for the sake of appearance while tissue is healing. Various functions of temporary denture for the partial edentulism strive to achieve the temporary goals with minimum time and cost.

Flexible dentures are becoming very popular nowadays. They are marketed as permanent, unbreakable and retentive restorations. Flexible dentures cost is higher than traditional removable partial dentures, but many patients pay that extra because of esthetics. Dentures with flexible framework are undeniably more esthetically pleasing than dentures with metal framework. Another property of Flexible partial denture is it follows or flexes with the contour of your arch even when it’s ill fitting.

Porcelain fused to metal crowns are constructed in metal alloy with porcelain fused to either all or most of its surface. PBC, also known as ceramics fused to metal dental crown is indicated in situations whrere a stronger restoration is needed, such as the presence of minimal interocclusal clearance. Compared to all ceramics dental crowns, the strength of this type of restoration is excellent.

Cantilever Bridge, also known as Cantilever Fixed Partial Denture, is a prosthesis where the pontic (artificial tooth) is supported on one side only by one or more abutment teeth. The pontic is attached to a single or to two retainers splinted together but has no connection at the other end of the artificial tooth. The abutment tooth or teeth may be either mesial or distal to the edentulous space.

Fixed Moveable Fixed Partial Denture, as we define before, is a partial denture (bridge) with a rigid connector usually at the distal end of the pontic and a moveable connector that allows some vertical movement of the mesial abutment tooth. The movable connector (precision or semi-precision attachment) resists both separation of the pontic from the retainer and lateral movement of the pontic.
Segmented dental bridge has a fixed-fixed partial denture segment and a fixed movable partial denture segment.
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. This basic design of FPD has a minimum of three units that can be cemented in one piece. The abutment teeth are rigidly splinted together and must be prepared parallel to each other. Its retainers or crowns should have approximately the same retention as each other. This is to minimized the risk that forces applied to the fixed-fixed FPD will dislodge one retainer from its abutment, leaving the FPD suspended from the other abutment.

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. This will allow a small degree or limited movement between the rigid component and the other abutment tooth or teeth. This movable joint will give full support to the pontic against vertical occlusal forces, and will allow limited movement in response to lateral forces.
The advantage of fixed movable dental bridge is that both retainers do not need to be parallel.
