The front teeth require special attention, because they are in the visible zone, the slightest defects are visible on them. It is believed that cermet on the front teeth is one of the most reliable and effective options for the reconstruction of the dentition. This is the most commonly used method of prosthetics. Its distribution is due to not too high price, durability and excellent aesthetic qualities.
A cermet crown is a fairly simple design, which consists of a frame made of metal and several ceramic layers. The frame can be made of different materials. Typically, platinum, gold, chromium, cobalt and nickel are used for its manufacture. Its thickness is up to 0.5 cm. Cobalt-chrome alloy is the most common of those currently used, followed by nickel-chrome. They combine well with gum tissue and are relatively inexpensive.
Platinum or gold frames last much longer, have better aesthetic qualities, but a much higher price. Ceramics is applied layer by layer to the frame made, and after applying each layer, it is fired in a special furnace at a temperature of 950 degrees. The result is a particularly strong bond between ceramic and metal. This ensures structural integrity over time.
Cermet on the front teeth has a number of indisputable advantages:
- great appearance;
- strength and reliability of the structure;
- long term of operation; such crowns made on the basis of inexpensive metals can last more than 10 years, and with a gold or platinum frame - more than 15 years;
- quite reasonable reasonable price.
However, not everything is as rosy as we would like. Ceramic metal on the front teeth has disadvantages:
- To establish such a crown, the tooth is sharpened very much;
- the incisor or fang is depulped before the installation of the crown (the nerve is killed) - the tooth remains more fragile than the “living” one under the crown.
Cermet on the front teeth is installed after a thorough preliminary preparation. First, an x-ray examination is performed. This is necessary in order to completely eliminate inflammation at the top of the tooth. If inflammation is detected, then the tooth must be cured and only then prosthetized. If there are old fillings in the teeth, it is necessary to find out how well they are installed. If defects are found, the channels are cleaned and refilled with filling material.
The tooth is carefully depulped. This is a prerequisite for anterior teeth having one common root. If necessary, caries is healed. In some cases, the installation of a
stump tab under the crown may be considered. If the tooth is half destroyed, a pin is inserted into its canal, and then the crown part is
extended with filling materials.Cermet tooth crown is installed after thorough grinding of the tooth. This is a lengthy process that must be performed with meticulous precision to ensure high quality prosthetics.
If you want to have beautiful front teeth, cermets, prices for which on average in Russia are about eight thousand rubles, the most suitable option. Do not spare money for a quality “reconstruction” of your smile. You will get the expected result and will enjoy it for many years.
