Few things about dental fillings

 

One of the first and obvious results of caries is the destruction of the tooth crown (the tooth portion that will stand in the oral cavity) to form a cavity within the tooth, as a rule, significantly exceeding the size of external damage.

After surgical treatment of cavities of decay, which is to remove all damaged and softened tooth tissues, there arises a problem of restoring the integrity of the tooth crown, which in medical practice, as well as in everyday life, is defined by the term "filling".

 

Dental filling with plastic filling material

 The most common method of filling is usage of plastic mixtures, which solidify after being injected into the cavity. Among this group of materials the most advanced are photopolymers – materials which are polymerized (solidified) by irradiation of intense light. In our clinic for permanent filling we use solely photopolymers of different chemical composition. Application of the photopolymerization is a significant factor affecting the quality of filling, because it enables the doctor to "turn" the mechanism of polymerization (solidifying) of the filling at the particular moment when the work is completed. In addition there is a number of technical aspects in the process of filling, where the usage of photopolymerization mechanism leads to a significant improvement in the quality of treatment.

Thus, the application of photopolymers can significantly improve thequality of filling. But due to the fact that the is nothing absolutely perfect in this world, plastic materials, including photopolymers have disadvantages. The main of them is a polymerization shrinkage - a reduction in the amount of material in the process of solidifying.

This characteristic gives rise to microcracks between the filling and the wall of the tooth and eventually leads to the loss of the filling or the occurrence of secondary caries process in the depressurization place.

 

Non-plastic (solid) filling materials

Manufacturers of plastic filling materials are conducting tireless and successful struggle for the reduction of polymerization shrinkage, but a radical way to deal with this drawback is the use of non-plastic (solid) filling materials. This is a completely different method of filling, which provides preliminary manufacturing of the destroyed part of the tooth, followed by embedding it into the tooth cavity   with the help of some sizing agent. Therefore, such a design that is put into the cavity of the tooth is called inlay.

Material from which ​​these inlays can be made are: metal, ceramic (porcelain) or a composite (organic resin with ceramic filler).

This filling method is superior to plastic filling materials accordint to all indicators except for two: 1) the treatment duration; 2) the cost of treatment.

 

Summary

Thus, the transition to professional advice about choosing the method of filling: if time allows and the financial factor does not limit you – give preference to inlays. Historyof this type of filling is more than 100 years. Nowadays, nothing more perfectis invented. This is - the long-term stability and this is as convincing as clinical results.
