Crown is needed when the original crown of the tooth has been demaged that it can not be repaired with filling. With crown we repair the visible part of the teeth functionally and aesthetically. If we will have enough tooth material, we can make construction. Sometimes tenon construction is needed in order to the stable strenghten, which will be fixed in the root canals. The crowns can be metal-based, metal-free, temporary and permanent crowns. The metal-based crowns can be molded crowns, full and part-covered crowns. The covering materials are composite-based materials ( mixture of resin and ceramic filling material) or ceramic is used. Finally, a special firing happens on 800-900 ° C, and an adhesive oxide layer will be formed. The fixed bridge is a denture with which the teeths that remedy the defects will be fixed on the remained teeths, in certain cases on the roots or on the the implants that replaces them.

Crowns and bridges can be made from the following materials:

• ceramic metal: the ceramic veneering will be covered on the nickel free metal frame
• zirconium: Completely metal-free solution
• press ceramic: completely metal-free and one of today’s most aesthetic and stable prosthesis

In case of proven metal alergy avoid the use of allergenic material, therefore we will offer you a solution individually.

The advantages of the metal-free (zirconium) crown:
They serve the restoration of the front teeths and the chewing organ. The frame is made of zircon which are high-precision and strenght castings. The ceramic layers are burned onto these frames. The opacity of the bridge is the proof that the bridge is metal-free. The color of the ceramic will be selected individually in every case. Like this the bridge is:

• completely metal-free, so it does not cause metal allergy,
• stronger than metals, tooth-colored and allows the light through
• porcelain veneer completely looks like the natural enamel
• natural aesthetic effect
• the most optimal light transmission
• there is no gray gumline
• because of the strong frame polynomial bridge can be made of it
• because of the computer technology, it’s highly precise and accurate

Disadvantage:

• more expensive than conventional metal-ceramic solution
