BRIDGE DENTAL

Tooth serves as a connecting element for a fixed partial denture is called a pillar . The artificial tooth that is based on a pontic abutments. The pontic is connected to the retainers fixed partial denture, it is onlays or crowns are cemented to the abutment teeth preparations. Intracoronary restores lack of retention and endurance needed to be used as retainers for fixed partial dentures. The connectors between the pontic and the retainer can be rigid (ie castings welded joints or connectors) or non-rigid (ie, precision attachments or stressbreakers).

A section is the space between natural teeth must be filled with the bridge. The ridge the edentulous ridge area that relies on the pontic. An intermediate pier abutment tooth is found between two pontics and supports so that each pontic is attached in turn to another abutment tooth. The term unit when applied in the field of bridges, refers to a retainer or a pontic. Thus a bridge with two retainers and pontic would have three units.

CORONA.

A crown is a restoration cemented extracoronary covering the outer surface of the clinical crown.

Can be completely made of gold alloy, or some other metal rust, with fired ceramic on metal, all-ceramic, resin and metal, or acrylic resin only. If one is of some parts of the clinical crown, the restoration is called partial coating crown.

Inlays can be used as single restorations for occlusal-proximal lesions or lesions Gingival extension with minimal to moderate. Can be made in gold alloy or ceramic. When modified with a coating occlusal restoration onlay intracoronary called and is useful to rebuild those back teeth that have a more extensive injury and require restorations, occlusal-distal half broad.
