Glass fibre post (composite post)

A tooth after root canal treatment is more brittle and requires a solid foundation for reconstruction. A glass fibre post and core strengthens the tooth from the inside, allowing it to be safely rebuilt with a composite or a prosthetic crown.

What is a post and core and when is it needed?

A post and core is an element placed in the tooth's root canal after root canal treatment is completed. We use it when the damage to the tooth crown is so extensive that a composite reconstruction alone would not have sufficient support. The glass fibre post transfers chewing forces along the root, reducing the risk of fracturing the weakened tooth.

How the post cementation process works at Mabel Clinic

The procedure is performed after checking the tightness of the root canal filling, usually during a single visit. The dentist prepares the space in the canal, fits the post, and cements it adhesively, so that the post, cement, and tooth form a single, durable structure. Immediately after placement, we rebuild the crown portion with composite or prepare the tooth for an all-ceramic crown.

Why fibreglass instead of metal

Glass fibre posts have an elasticity similar to natural dentin, so they absorb chewing forces instead of accumulating stress, as was the case with rigid metal posts. They are also translucent, so they do not show through the restoration and do not compromise aesthetics, which is of particular importance in the smile zone. This is a modern standard for tooth reconstruction after root canal treatment.
