Tooth filling with plastic

introduction

Around carious defects to remove and the affected tooth Being able to provide permanent care afterwards is one thing Tooth filling necessary. After the attending dentist the Caries completely removed and the resulting hole (cavity) has drained, he can fall back on different filling materials.

Basically, the Dentistry differentiated between rigid and plastic materials.

Plastic filling materials are introduced into the tooth in a deformable state, adapted to the specific tooth shape and only then hardened.
Rigid materials however, they have to be made in the laboratory using an impression.

Both amalgam and plastic fillings belong to the group of plastic tooth fillings, while so-called inlays or onlays belong to the rigid types of fillings. A dental filling made of plastic can be made quickly and easily in the practice.

In cases where the carious defect extends to the Pulp is enough to protect the Nerve fibers first placed an underfill. The dentist uses a drug to do this Calcium hydroxide- Base, which has a calming effect on the nerve fibers and is intended to stimulate the formation of new dentin.

With an extensive Tooth filling must have a so-called die attached and fixed with small wedges.

Then the tooth has to be drained and a connection between the natural tooth structure and the plastic has to be established.
The attending dentist can then gradually insert the filling material into the cavity bring in. In order to prevent the material from falling out early, it is advisable to gradually introduce small amounts of the material and allow it to harden.
With this method, it takes longer until the entire tooth is filled, but it can usually be determined that the plastic tooth filling can remain in the tooth longer.
After the cavity is completely filled, the surface of the filling material can be adapted to the natural tooth shape.

Advantages of the plastic filling

advantages When choosing a suitable filling material, several factors have to be weighed against each other.
Amalgam fillings are comparatively inexpensive, are in most cases even covered by health insurances without additional payments and can withstand the stress of chewing pressure.
However, due to their color, they are quite unsightly and can tooth Only stabilize to a limited extent in the case of high loss of substance.
Composite fillings (Plastic fillings), on the other hand, can be adapted to the natural tooth color and are almost invisible to the layperson. Furthermore, no organ-damaging properties of the filling material are known from time to time, including the occurrence of allergic reactions or other incompatibilities can hardly be observed.

Both in the durability, as well as in the resistance to the chewing pressure loads, are Dental fillings made of plastic - equivalent to amalgam fillings nowadays. In addition, plastic fillings have a stabilizing effect on the filled tooth if there is a large loss of substance. This fact is due to the fact that the plastic (Composite) stuck to the tooth substance and thus the pressures acting on the tooth are better distributed.
In contrast to amalgam-filled teeth, a tooth with a plastic filling usually does not show any increased temperature sensitivity.

Disadvantages of the plastic filling

To meet the demands of a high quality Filling material to meet are Plastics (Composide) extremely expensive to manufacture. The cost of producing one gram of plastic suitable for filling corresponds roughly to the price of one Grammes Gold.

In addition, both the treatment process and the subsequent grinding in of an optimal plastic tooth filling are very complex. For these reasons it is easy to see that such a filling has its price. In addition, the costs for the production of a plastic filling are only partly borne by the statutory health insurance companies.
The patient has to go for one Difference amount come up yourself. In addition to the high cost, the susceptibility to discoloration is another disadvantage of composite fillings.

The cost of a plastic tooth filling is quite variable within Germany. It is important for the patient to know that the health insurances only cover a part of this filling material. See also below under "How expensive is a plastic filling?"

In addition, plastic fillings discolour Smokers or with frequent coffee and tea consumption with time. This is not the case with ceramic fillings.

How expensive is a plastic filling?

The statutory health insurance companies plastic tooth fillings actually have Not in your Service catalog. But there is Exceptions.

Plastic tooth fillings are usually tooth color, that means when looking at it with the naked eye no difference should be discernible between the filling and the tooth.

In Primnzip, the statutory health insurances only pay the costs that would arise if a patient opted for a tooth filling amalgam decides. Amalgam fillings are still considered to be Standard supply. And that's exactly what the statutory health insurance companies pay for.

Dental fillings are an exception plastic in the Anterior region. Here are the costs from the legal Health insurance borne because a dental filling made of amalgam is not aesthetically pleasing.

Dental fillings made of plastic, unlike amalgam, must be in a Multi-layer technology getting produced. For that is more time necessary and that too Material is more expensive. Therefore, in this case, the dentists require one from the patient Co-payment. This means that the patient has to pay the costs that go beyond the amalgam filling. Depending on the size of the filling and the amount of work that is required, you can up to 150 euros in costs for the patient. Exactly how high the costs are varies from dentist to dentist.

Shelf life of plastic fillings

When it comes to the fillings plastic it is a material that has an intimate relationship with the tooth, which means that it sticks very firmly to the tooth and is therefore also very close. Bacteria can no longer slip into the gap between the tooth and the plastic tooth filling and destroy the tooth. This means that a properly manufactured plastic tooth filling has a very long shelf life.

The plastic tooth filling is very sticky firmly on the tooth and stabilized thereby the tooth. This extends the shelf life of the tooth and the tooth filling equally.

Because the Plastic does not loosen through chewing or saliva can become, it will not become less. The durability can therefore be regarded as very high. The durability of the plastic tooth filling is further extended by the fact that No plaque or bacteria or hardly on plastic deposit. The plastic is very smooth and therefore offers little hold.

The durability a plastic filling can through insufficient dryness during filling of the tooth reduced become. If the dryness is not given, the plastic can break down not firmly attached to the tooth and this creates gaps through which bacteria can get into the tooth.

Because of this, when filling Rubber dam used. This is a rubber blanket that is stretched over the patient's mouth and only the tooth to be filled or its neighboring teeth are not covered by the rubber. On the one hand, the other teeth protected and on the other hand he can saliva do not bother during filling and the Keeping dry is guaranteed. If it is not possible to place a rubber dam, you are done Cotton rolls and careful suction to achieve a relative drainage.

Are there any allergies to plastic fillings?

Tooth fillings made of plastic usually consist of a kind of modeling clay that is placed in the tooth. The mass is then irradiated with ultraviolet light to allow it to harden. The plastic tooth fillings are light-curing.

The plastic tooth filling contains acrylates. If you are known to be allergic to acrylates, you should refrain from using a plastic tooth filling.

Very few people suffer from an allergy to acrylates, as acrylates can be found in numerous objects in our everyday life. It is more than rare that people actually develop an allergy to their plastic tooth filling and then show clear symptoms. Usually another tooth filling, a crown or braces can be identified as the cause of the allergy.

Once a plastic tooth filling is attached to the tooth, the saliva can no longer detach any components. But without released components that are absorbed into the body's own cells, no allergy can be caused.

Tooth fillings made of amalgam are much more dangerous in terms of health. When chewing, tiny particles of mercury can be released and absorbed into the body. High levels of mercury in the body in many amalgam fillings are not necessarily uncommon.

Tooth fillings made of plastic can be regarded as harmless to health. It is more than unlikely that they cause an allergy.

Ceramic compared to plastic filling

In principle there is no ceramic fillingssince ceramic one rigid material is that it always has to be fired in the furnace at very high temperatures or cut out of a prefabricated block (CAD / CAM technology). It is then about Ceramic inlays, so Inlay fillings, the ones from Dental technician made in the laboratory are then used by the dentist. The patient has to go to the dentist's appointment at least twice until the ceramic insert is fixed in the tooth.

Ceramic has the advantage that it can be used as an inlay filling Stabilize tooth can. It's very stable and the colour can perfectly adapted to the individual tooth color become. Such an inlay filling made of ceramic is used when the defect in the tooth is very large.

Ceramic gives bacteria a bad hold, so they can grow Not with time discolored but actually keeps the same color in the mouth for the rest of its life. A prerequisite for this is, however Ggood oral hygienewhich includes the regular use of dental floss.

Of the Disadvantage of a ceramic inlay they are a lot higher cost compared to the plastic filling (approx. 600 €) that longer waiting time and that they cannot be repaired. In addition, a ceramic insert filling that is only slightly too high leads to wear of the tooth compared to the other jaw, because Ceramics essential is harder than the enamel. Temporomandibular joint problems are the result.
