Bridge (dentistry)

（重定向自Dental bridge）

A three unit porcelain fused to metal bridge (PFM) made by a dental technician.

A semi-precision attachment between teeth #3 and #4, with the female on #4. Note the lingual buttons extending, in the photo, upward on #2 (on the left) and downward on #4. These are used to grasp the crowns with a hemostat and make them easier to handle. They can also be used to aid in removal of the crown in case there is an excessive amount of retention during the try-in. They are cut off prior to final cementation.

The proximal surfaces of the pre-solder index abutment and pontic, showing lab-processed grooves for added retention of the GC pattern resin.

The abument and pontic joined with GC pattern resin in a solder index and reinforced with an old bur (lying horizontally across the occlusal surface of the copings).

A bridge is a fixed dental restoration (a fixed dental prosthesis) used to replace a missing tooth (or several teeth) by joining an artificial tooth permanently to adjacent teeth or dental implants.

Types of bridges may vary, depending upon how they are fabricated and the way they anchor to the adjacent teeth. Conventionally, bridges are made using the indirect method of restoration. However, bridges can be fabricated directly in the mouth using such materials as composite resin.
