The basic aim of dentistry is to preserve natural teeth as long and as far as possible. However, tooth preservation is not possible in all cases of dental treatment.
Various causes can lead to the fact that a dental prosthesis is unavoidable. Tooth loss can be the result of untreated caries or periodontitis, underlying diseases can attack teeth and jaws, external influences such as accidents can lead to tooth loss. In the vast majority of cases where comprehensive dental prostheses are required, the patients are older. Often the poorer bone substance is one of the causes.
But even in younger years it can come to losses of teeth. What is even more often the case is the necessity of tooth fillings. Very few people in this country can have a healthy set of teeth without any filling.
Dental fillings are one of the most commonly used dental conservation measures, especially when it comes to tooth decay. If the damage to teeth is too far advanced, crowning them is often a good solution for tooth preservation. The tooth is then ground, preserved with the root and covered with a crown that makes it look natural and protects it from tooth loss.
Materials for plastic dental prostheses and fillings
Modern dentistry has many different materials available for dental prostheses, fillings and crowns. These include
- Gold alloys,
- and plastic.
The aim of the continuous improvement of the technical possibilities for dental prostheses and fillings is, of course, above all to achieve a long durability. At the same time, dental prostheses and fillings should be well tolerated, and they should look as good as possible like natural teeth.
The latter is particularly successful with ceramics because they are translucent, show no discoloration and withstand the stresses well. But plastic has also caught up in dentistry. Modern plastics for dental fillings and dentures are much stronger and more durable than they used to be.
In recent decades, many people have opted for plastic dental fillings because amalgam had acquired a bad reputation as a result of a number of reports. Plastic for dental fillings and dentures has several advantages. One of these is good formability. Another advantage is the cost factor.
Even very high-quality and modern plastics are generally cheaper than, for example, ceramics or gold alloys. Although plastics still show slightly greater abrasion than some other fillings and tooth replacement materials, they have now achieved excellent durability.
In order to achieve better hardness, quartz, glass and other additives are added to the plastics for dental prostheses and crowns today, which additionally harden the plastic. In addition, the plastics can now also be very well adapted to natural teeth in terms of shade. Plastic is not translucent like ceramic. Therefore, there can still be slight differences even with very good fitting, but some of them are already negligible. A dental prosthesis made of this material is particularly inconspicuous when a prosthesis is made of it, a partial denture or a veneer with several crowns in the anterior denture.
Allergies and care for plastic dentures
It can happen that people react allergically to plastic or certain components, especially when large dental prostheses are required. In principle, the dentist should be informed about all known allergies during the conversation about a dental prosthesis, but also about the material of fillings and any treatment at all.
Anyone who is highly allergic will generally be advised by a dentist to have an appropriate dental prosthesis and fillings that certainly do not cause any reactions. Should any allergic reactions occur with a prosthesis made of plastic, this can be remedied by an exchange or other treatment.
This is easier with a crown or dental prosthesis than with a filling. However, fillings are rarely so large that they cause reactions. This is more often the case with a larger prosthesis restoration.
Modern plastics are largely free of side effects. The care of plastic dentures does not differ from the usual care of teeth and dentures. In the case of fixed dentures, the usual dental care can be carried out. However, it is particularly important to avoid too much pressure when brushing and too hard brushing.
