PORCELAIN FUSED TO METAL PROSTHESIS – ADVANTAGES AND MANUFACTURING TECHNOLOGY
Thanks to the durability, strength, aesthetics and reasonable cost of porcelain fused to metal crowns, these crowns are widely used in modern dentistry.
The frame made of nickel-chromium or cobalt-chromium alloy creates the basis of the crown. On the top this frame is covered with several layers of ceramic paste and then the crown is subjected to firing in a special oven at a temperature of 800-900 degrees.
THE PROCEDURE OF INSTALLING PORCELAIN FUSED TO METAL CROWNS
Before the installment, if necessary, mucous membrane and teeth are treated.
The first preparatory stage in prosthetics is teeth facing which will serve as support for cemented bridge or an individual crown. The patient can make himself comfortable in a soft orthopedic chair with memory effect enabling to relax during all procedures. The procedure is performed under the constant supervision, since the thickness of peeled teeth should be enough to withstand the load during wearing crowns.
After preparation of the tooth stump the dentist makes cast model on the basis of which the dental technician produces the construction within a couple of days. During this period the dentists can offer to manufacture temporary crowns, if the installation of porcelain fused to metal is planned in the frontal area.
The next step is fitting a metal frame and a minor completion of the frame before applying ceramics in the dental lab.
Installation of crowns is carried out with special dental cement. Fixing a crown or bridge takes only a few minutes.
