Materials used to create dental bridges include porcelain fused to metal restorations, all-ceramic and zirconia bridges.
Porcelain Fused to Metal Bridge
A porcelain fused to metal bridge has a thin metal substructure covered with porcelain. Traditionally, most bridges were fabricated this way as the results look good and are durable. However, a porcelain fused to metal bridge is not quite as aesthetically pleasing as a metal-free restoration. The metal can create an opaque effect as light cannot pass through the bridge.
All-Ceramic Bridge
An all-ceramic bridge made from a material like e.max provides a stunningly lifelike restoration that is highly suitable for restoring front teeth where aesthetics are critically important. The materials used for these bridges replicate real teeth very closely, and because they are entirely made from porcelain, light can pass through unobstructed. All-ceramic bridges are ideal for front teeth and are typically used to create three-unit or three teeth bridges. They can be less suitable for larger bridges.
Zirconia Bridge
Modern zirconia bridges also look extremely lifelike and are extremely strong. These bridges are suitable for anywhere in the mouth, including for people with bruxism. A zirconia bridge can restore multiple missing teeth. Full-arch zirconia bridges can restore an entire set of upper or lower teeth using dental implants for support.
