Bridges are fixed dental prosthesis that are attached to the adjacent tooth mechanically by cement. The advantage of a bridge is it is fixed.Hence there is increased comfort. In case of long span edentulousspace when there is not enough tooth to support the bridge, Implants could be placed to support the bride.The bridge could be either screwed or cemented onto the implant.
The bridges can be made of metals like cobalt-chromium,Gold and Titanium, Porcelain fused to metal, aesthetic all ceramics and newer Zirconia. The CAD-CAM system has changed the old system of casting and now more precise adaptation and aesthetics of the bridge are achieved by laser sintering andmilling.
