Photopolymer fillings: what is it, reviews
Nowadays, few, where you can find any other filling materials in addition to the photopolymer or the so-called light-curing. Of course there is the state dental clinics, which put the fillings are chemically curing, i.e., dry themselves under the influence of temperature of the oral cavity. But very few of them. Light cure materials, due to their content of the photopolymer. The seal hardens under the influence of special UV light. Their use is very widespread. And they have a number of advantages:
- The ability to choose the appropriate color;
- To give the necessary form;
- Have good adhesive properties;
- To restore all groups of teeth.
What are and when to use
Any photopolymer fillings is a composite material. Themselves composites differ among themselves on macrolipasemia, micro-filled, minneapoline, hybrid and compomers. Also they are solid and flowable. Are special syringes. They are applied with special tools, because it is impossible to do, due to the fact that the material sticks to the tool. The flowable polymeric seals are very convenient to use when you restore interdental contact point and the filling of the cavities of the fifth class in black, that is the cervical area. They lie evenly and fit snugly, creating a solid contact with the tissues of the tooth. They are very convenient to use. Excluded the possibility of imposing more than necessary.
Solid photopolymers very good restoration, especially the front teeth. Due to its plasticity they can be given any shape and thus to reproduce the anatomic form of the tooth planiruyuschegosya. They need to be applied in layers, if the cavity is extensive. Because the rays from the lamp may not reach deeper layers. The thickness should not exceed 2-3 mm. we need first to Shine through the enamel to the polymer material fit snugly to the wall. And then on top of it. So fixing will be better.
The formation of cavities for light-curing materials
When placed the usual filling, the cavity must be formed strictly according to the rules, depending on the class of caries. This is due to the fact that a link is created between the tooth and seal only mechanical. And composite, thanks to its composition still can chemically interact with tooth tissues. The only requirement is the creation of a fold or bevel the enamel wall at an angle of 45 degrees across the cavity. It is necessary for the best adhesion and hide the edges of the fillings in enamel. Accordingly, it is necessary the removal of all infected dentine. Be sure to carry out the dissection with the water supply to the dental tissues are not overheated. In extreme cases, you can take frequent breaks, but it is less reliable.
Installation technology light-curing composite materials
As is clear from the above, photopolymer fillings put differently. Other plombochki establish one portion and dentist only have time to stamp it. Because they are frozen within one to two minutes. And then ground off the excess and polished. And to set the light things a little differently. Step by step it will look like the following:
- Anesthesia, if required;
- Dissection of carious cavity;
- Medicated treatment;
- Isolation from saliva and drying;
- Etching of the enamel;
- Washing and drying;
- The application of the adhesive;
- Installation of the filling material layers;
- Grinding and polishing.
Depending on the depth of the process may require a different material, as an insulating and lining. In those cases where the affected layers of the dentin they must be isolated. But if the cavity is very deep and there was only a thin wall, first put the medical material, and then isolating. Etching of the enamel can be carried out before insulation, and after it. Because etching gel phosphoric acid has an effect on tooth enamel. It should be applied on absolutely dry surface to achieve the desired effect. Hold twenty seconds, then washed with the same, simultaneously collecting all of the liquid saliva ejectors. As strange as it may sound, you need to dry those 20 seconds.
After that, adhesive is applied to the system. Its a bit sprayed a weak stream of air from a pistol, to get all the surfaces and slits. Gleaming light bulb. Time depends on the manufacturer. Is usually from 20 to 40 seconds. The same applies to the seals. It must be put into the cavity a little bit. Better not to hurry with this case. Imposing piece by piece it formed a beautiful blombacka, which aesthetically will not differ from their natural teeth. After this is the final stage. If the seal overstates the bite, that is great, then ground off the necessary places. Where to define a special clean piece of paper. Then polished to give a natural Shine and smoothness.
Much depends not only on the material, the doctor and his competence, but also from the patient. Of course, even among the photopolymer may be such that less durable. If the material set is good, it should last for about five years, maybe even seven.
If a filling fell out immediately, it can mean either a mistake of a doctor during treatment or it’s the fault of the patient, which do not comply with these tips. In the first case, a more frequent cause is the violation of adhesion due to ingress of liquid, saliva, blood, etc. Also, if the dentist neglects his work, he can set the seal of poor quality. In such cases, dentists, therapists usually give a one year warranty. If during this time the seal fell, despite the fact that the patient has complied with all rules for the care, specialist sets the seal again for free. In any case, you should turn to a trusted dentist.
What can and what can not after the installation of filling material of photopolymer
In addition the installation of light seals and require appropriate care. If the patient will follow all the recommendations, then the seal will last for years to him.
- A big plus is that you can eat immediately after sealing, instead of waiting for two hours, as in other cases. But in the first few days is to abandon the ink products. Because only the installed seal can absorb the dyes, and she immediately darken and become visible. It is better to suffer for a few days. The same applies to solid hard food.
- Also desirable to use a liquid and chewable products. They can cause loss of material.
- You can’t chew nuts, crackers, eat solid fruits and vegetables if you have made the restoration of anterior teeth.
- Moreover, it is forbidden to eat the skin, biting your nails and to keep teeth solid object.
- Be sure to clean as well as your own.
- Go to a professional cleaning every six months. But be sure to warn the periodontist that has light seals and specify their location. Otherwise, ultrasonic cleaning can create a crack or chip on the surface of the filling material.
If to observe all recommendations of the doctor, the seal will long to please.
