What are fixed dentures?
Fixed dentures allow missing or damaged teeth to be replaced. They are fixed because they are permanently affixed, that is, they cannot be removed independently.
They are cemented to natural teeth.
Fixed dentures
Replaces missing teeth.
Restores destroyed teeth.
Improves aesthetics.
The types of fixed prostheses
Crowns.
Bridges.
Veneers.
Inlays.
Maryland bridge.
California bridge.
What are the advantages
Aesthetic and functional.
The benefits
Fixed prosthetics has the primary function of restoring full function to the existing tooth and replacing it if it is missing.
It improves and perfects aesthetics. It is the details that make the difference.
It facilitates daily oral hygiene by improving the anatomical shape of teeth.The best material for making fixed dentures is zirconium-ceramic: zirconium for the inner layer, ceramic for the outer layer.
The materials
It is a biocompatible material that provides solidity and strength to the prosthesis and, thanks to its translucency, is practically the same as a natural tooth.
Zirconium-ceramic capsules do not have black edges and it is very difficult to distinguish them from natural teeth.
In some cases lithium disilicate (inlays), a material very similar to zirconium ceramic, is used. Only in very rare cases is metal-ceramic (gold) used.
Types of fixed dentures
Single crown
The crown is a prosthesis for a single tooth that has lost a lot of tooth substance but still has a root. It is cemented to the appropriately prepared tooth (abutment). The crown makes it possible to recover a destroyed tooth and preserve it for many years.
Bridge
The bridge allows the rehabilitation of areas where a tooth has been lost by taking advantage of those still present. The bridge can be applied in a space between two existing, anatomically sound, firmly rooted teeth (bridge abutment teeth) that have been properly prepared.
The application of the bridge is an established technique without surgery. In cases where the abutment teeth are compromised, treatment and filing are necessary.
When applying a single block, daily hygiene may be more difficult but should be carried out thoroughly on a daily basis, using toothbrushes and super floss. It is important to maintain healthy abutment teeth.
Veneers
Veneers are thin ceramic foils that are cemented onto the outer (vestibular) surface of teeth that are visible when smiling.
The natural teeth are suitably prepared, with a light filing, to accommodate the veneers, removing a light layer of enamel, while retaining the larger part of the teeth.
