The cost is based on each unit. A unit represents a tooth. The bridge will have a minimum of two anchor teeth. Typically, an anchor tooth on each side of the missing teeth/tooth.
Bridges: patients have two options for materials used to make the units on the bridge, either Zirconia or Porcelain Fused to High Noble Metal (PFM).
Porcelain fused to high noble metal (PFM). PFM bridges and crowns can be thought of as a hybrid as they are made from both all -metal and all-ceramic materials. A metal alloy is used to create a thin thimble-like “cap” that fits snugly over the tooth. Porcelain is then fused over the substructure to form the shape of the unit or crown and give it a white tooth-like appearance. Porcelain-fused-to-metal restorations have a 50+ year track record of providing lasting and durable service.
01. Advantages of PFM
• Even if some of its surface layer of porcelain fractures off, the metal substructure underneath will characteristically stay intact thus maintaining the crown’s seal over, and reinforcement of, the tooth. In comparison, the full thickness of an all-ceramic may fracture, thus compromising both functions.
02. Disadvantages of PFM
• For posterior teeth that show (like premolars and 1st molars) the added strength that a PFM offers might make its possibly just-average appearance an acceptable tradeoff.
• PFMs require a greater amount of tooth reduction (trimming) than their all-metal and Zirconia counterparts.
• Some people are allergic to the metals used.
• Corrosion is sometimes a concern with these materials.
