Post-and-Core Build-up With Composite Materials and Glass Fiber Posts
Glass fiber posts are a supportive means that helps restore the shape of the tooth when it lacks a sufficient tooth structure to retain the core. They are used in combination with a composite filling, which gets hard by curing it with a special light source.
Whether the procedure is needed, it is determined during a regular checkup. It is usually needed before restoration when two lateral walls of the tooth are missing. This approach of restoration is applicable only when at least 2 mm of the remaining tooth structure above the gum line is left – only then the restoration will be of high-quality and long-lasting. Then a dental crown is placed over the tooth.
How Is the Procedure Performed?
The procedure usually takes up to 1 hour; it can be done in a single visit.
Before this procedure, the patient should undergo root canal treatment. Then the posts are cemented, and the shape of the tooth is restored with a composite filling, which gets hard by curing it with a special light source. The posts are tightly anchored to the roots of the tooth and the filing – a compact, tight monoblock is obtained.
