Frame metal ceramic crown is made from an alloy of metals, mainly cobalt-chromium or Nickel-chromium alloy by casting. Sometimes for casting metal cap used alloys of precious metals. These crowns look more aesthetically pleasing, but are much more expensive.
Metal cap layers are applied to the ceramic mass, each deposited layer is annealed in a special kiln. The use of ceramics with different physical characteristics, you will ultimately get a crown that completely mimics the optical properties of dental hard tissue. Ceramic is applied taking into account the anatomical shape of the restored tooth, therefore resulting in appearance the crown will match the natural tooth. It is possible to manufacture both single crowns and bridges. The service life of these products is 5 years, although they can last You much longer.

Most cements used in the prosthetic posterior teeth, but when it comes to the restoration of the front teeth, the alternative is prosthetics designs. These crowns can be represented in the form of pressed ceramics, made by technology E. max, or ceramic crowns on zirconium oxide. Crowns on zirconium oxide possess great strength and high aesthetics; they are much thinner, lighter than metal-ceramic counterparts. The cap is made of zirconium oxide milled with the aid of computer technology, completely eliminating the human factor. This ensures high accuracy of fit of this design. That is why the front teeth prosthesis preference is given to metal-free crowns on zirconium oxide.
An important issue with dentures is the condition of the root canal and surrounding tissues. The most frequently asked question in this case: "should I Leave You tooth crown alive?". To answer this question can only be a doctor, considering multiple factors. In Your first visit conducted x-rays of the tooth/teeth that will be covered by crowns. On sighting the prices you can determine the presence of inflammatory foci near the root apex, but if the tooth before that it was treated – the presence of filling material in the root canals and sealing quality. In the presence of inflammation the tooth is definitely subjected to endodontic treatment. If the root canals are sealed, and near the top is an inflammatory lesion, treatment option may become subseroasa operation – resection of the root with simultaneous cystectomy.
When ceramic prosthetics removed sufficiently large layer of hard tissue up to 1.5 mm compared to the tooth preparation for all-ceramic crowns (up to 0.6 mm). Such aggressive influence on a living tooth can cause overheating of the pulp, causing inflammation, therefore, to keep alive their teeth under the cermet is impractical.
The procedure for fabrication of metal-ceramic crowns occurs in several stages:
