Porcelain fused to metal dental crowns have the following layers: enamel, body dentin, gingival dentin, opaque and metal coping.

Porcelain fused to metal dental crown

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.

All Ceramic Fixed Partial Denture with CAD CAM milled Zirconia Framework

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.

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 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.
