There are many ways in which a tooth can be damaged: the crown might be fractured, there might be a large cavity, you might have an infection in the root, or a previous filling may fall out. It’s important, though, not to wait until the problem gets worse: make an appointment with your dentist as soon as possible. Your dentist will then examine your teeth and determine what needs to be done.
When too much of the crown needs to be drilled away because of a large cavity, the structure of the tooth gets compromised. It is the tooth crown that needs to be restored to ensure proper function and aesthetics.
Conventional restoration consists in preparing the tooth for a crown, which means that almost all of the enamel is cut away. This makes the tooth much more susceptible to further tooth decay and the whole structure weaker. Even though in theory the tooth is protected by the new crown, secondary decay sometimes develops which leads to further problems and eventually to the loss of the tooth. Secondary caries can also develop in restorations (or fillings) done with composite filling – due to polymerization shrinkage. This is why it is a good idea to reinforce large restoration: to ensure its durability and prevent the risk of secondary caries.
In biomimetic dentistry, the goal is to preserve as much of the original tooth as possible and, when this is not possible, to rebuild the tooth by mimicking the original structure.
This means layering different types of materials, especially composite materials and fiber reinforcement. If done well, such a restoration has the same architecture, characteristics, and even aesthetics as a healthy tooth. Reinforcing the restoration with Dentapreg UFM will result in a restoration resistent against chewing forces and polymerization shrinkage.
A root canal treatment is necessary when tooth decay progresses through enamel and dentin into the pulp and develops into an abscess.
An abscess is an extremely painful pus-filled pocket that forms at the end of a tooth’s root, as this is the very spot with many nerves.At this point, a root canal therapy is usually performed by your dentist or endodontist to remove the abscess and the infected pulp.
In order to retain an artificial crown of an endodontically treated tooth, the dentist will use a post and core technique to substitute the missing tissue and to build the crown on it. Conventional prefabricated posts (metal or glass) need drilling and often disproportionate removal of healthy root tissue, which weakens the root and leads to stress concentration in the root – and therefore can cause root fracture.
When drilled, the root canal is automatically weakened and at high risk of root fracture. Extremely subtle minimally invasive pins can avoid such risk – they don't require drilling and can adapt to any shape of a root canal.
Dentapreg PINPosts are thin, flexible and do not require drilling as they can be simply inserted into the root canal without weakening it and adapt to its shape and diameter. Also, the way they are arranged contributes to better distribution of the load from mastication (chewing), thus preventing the risk of root fracture.At the same time, they have all the advantages of fiber reinforced composites – they are metal-free, aesthetic and reliable.
