Core build-up

A core build-up is used whenever we have teeth severely affected by tissue loss and the remaining healthy part is insufficient to ensure their basic structural stability. Replacing the missing tooth structure through a core build-up will give us enough retention and support for safely placing a crown. The shape of the build-up will be idealized as much as possible, so that a more conservative preparation is allowed.

The most common causes that lead to the need for a core-build up are extensive tooth decay, large failing obturations and dental fractures. Sometimes the destruction is so large, that the pulp chamber is compromised. In this case, a root canal treatment is required first and to better secure the build-up, we might use an endodontically retained glass fiber post to anchor it to the remaining tooth.

What types of materials are used for build-ups?

In our clinic we like to use premium quality materials because they are long-lasting and this gives us confidence when placing a crown over the reconstructed tooth. Moreover, the risk of complications is significantly reduced.

There are mainly two types of materials that we use for direct restorations through build-ups:

• glass-ionomer cements
• composite resins.

Choosing one over the other is dependent mainly on whether the tooth has had a root canal treatment or not, but also on the treating doctor’s preference.

Glass-ionomer cements are a type of cement that can be prepared in the dental office and they usually contain minerals that strengthen the tooth and keep the pulp healthy. They also act as a blocking agent, as they prevent bacteria from spreading. They are mainly used for vital teeth.

Composite resins are filling materials that are shaped directly on the tooth surface and then hardened with a special blue light. They can be used both in vital and non-vital teeth. They are also compatible with glass fiber posts.

After getting a core-build up

After the build-up the tooth is strong enough to sustain a dental crown. A proper dental hygiene and regular check-ups will ensure that no decay evolves under the restoration. We also recommend a healthy diet with less sugary foods and more fruit and vegetables.
