It is a conservative treatment system that is applied to the empty space without doing any preperations to the adjecent teeth.
Recently, glass fiber-reinforced resin-bonded composite backfill bridges started to be applied for prosthetic restorations with aesthetic purposes. It is a conservative (preserving tooth tissue) application that can be used for a long time.
The biggest advantage of these fiberglass bridges is that they can be applied quickly in the clinic and they are bounded stongly. They are strong bridges and they are aesthetic because they do not have metal infrastructure.
They can be used in anterior and posterior regions.
Between the front and rear teeth a fiber substrate is glued and filled with composite material.
