A functional, good-looking solution when replacing a missing tooth can be a Three-Unit Bridge. With this type of bridge, an artificial tooth is connected to the abutment teeth on each end to dental crowns.
Three Unit Bridges can be made of gold, porcelain, or porcelain fused-to-metal. They are used to replace a missing front tooth by reducing the teeth on either side, taking into account that the amount and type of reduction varies slightly according to the materials used.
These types of restorations have several advantages. They are aesthetic, functional, predictable, reliable, and more affordable than dental implants. In addition, Three Unit Bridges require less time for final result, help to prevent teeth from shifting, and crowns supporting the bridge on each side serve as restorations for the adjacent teeth if they have damage or decay.
On the other hand, Three Unit Bridges require enamel removal of adjacent teeth, and if adjacent teeth have crowns, they have to be redone. Another disadvantage of these restorations is that tooth decay is a potential problem.
Placing a Three Unit Bridge usually takes two dental visits because it is custom-crafted in a dental laboratory. On the first visit, the dentist numbs the area, makes sure any tooth decay is removed, takes an impression to recreate the natural bite as accurate as possible, and places a temporary bridge. Finally, on the second appointment, the temporary bridge is removed, and the dentist cements in place the new bridge once the fit and bite have been checked.
