Dental Restoration with Pin Abutments
Pin abutments become necessary when the tooth defects have progressed so far that the natural tooth crown is largely or completely missing. With the help of posts, a durable connection between the root and the tooth crown can be constructed.
Parapulpal posts
If a tooth is vital and still has enough tooth structure, parapulpal posts can also be used. These posts are then anchored around the pulp cavity to stabilise a filling.
Root posts
Root posts are posts that are anchored directly into the root. Such posts are used for root-treated teeth.
The root posts are made of different materials, such as titanium, zirconium, glass fibre… The appropriate pre-drill provides the optimal space so that the post gets a good hold in the tooth root. With a special bonding agent, the root post is then firmly inserted.
High-quality root posts have a good bending elasticity, which corresponds to the natural tooth. In this way, the naturally occurring forces and tensions of the tooth crown and root can be balanced out.
An abutment is placed on the post and then a dental crown is made in the dental laboratory to completely restore the function and shape of the tooth. This restorative measure is also considered a minimally invasive treatment method, as the only alternative would be tooth removal.
