A porcelain fixed bridge is used to replace a missing tooth or teeth. They are fixed (cannot be removed) and are often made of porcelain or a porcelain with a substrate made of Alumina or Zirconia. The types of fixed dental bridge include conventional, cantilever resin-bonded and implant supported.
The conventional and cantilever bridges require shaping of the teeth surrounding a missing tooth. Crowns are then placed on the shaped teeth and attached to an artificial tooth. A resin-bonded bridge requires less preparation of adjacent teeth and if often used to replace front teeth. The porcelain bridge is used to restore the functionality and aesthetic when one or several teeth are missing with an aesthetic custom-designed restoration. Either way, it is very sturdy and long lasting.
Just like a crown, a porcelain fixed bridge requires sending a regular or digital dental impression of the teeth prepared by a dentist to a dental laboratory for fabrication the bridge. The method of fabricating porcelain restorations may differ in the lab depending on what type of porcelain (ceramic) is used. The bridge can then be inserted at a subsequent dental appointment.
Using this method allows a lab technician to use superior restorative materials and techniques to fabricate a strong crown as well as his artistry skills to create a life like restoration, which would not be possible inside the mouth. Talk to your dental care team to determine if you are a good candidate for a porcelain crown.
