Dental crowns are caps that cover a tooth or a dental implant. Dentists often recommend crowns as a way to support broken, weak or misaligned teeth. Dental crowns can also be used to cover a tooth that is heavily worn or heavily yellowed. They can also be used in conjunction with bridges to strengthen multiple teeth. When it comes to the materials from which crowns are made, you have several possible options, including metal-ceramic, full zircon, e-max. Another option that is now available to some people is a zirconia crown. Zirconia crowns are made from zirconium dioxide, a very durable type of metal that binds to titanium, although it is categorized as a type of ceramic crown.
We are equal in front of the dentist, but the dentists between them are different.
1)Manually prepared zircon: This type of zircon is prepared manually by means of a simple apparatus similar to that of copying keys.
2) Zircon prepared with Cad-Cam: This type of zircon is prepared in a computerized way, the tooth model is scanned by an optical reader, then the computer prepares the three-dimensional model and the modeling is done, then a computer device brakes and prepares the zirconium, all this is done in a computerized way and without being touched by hand. The advantages of this method are:
a-Strength and resistance to chewing
b-Maximum compatibility with the tooth and gums as a result of the computerized process
c-Greater aesthetics, as it has 60% light transmission.
3) Recently, a type of zircon has appeared on the market which is stronger than metal, it is prepared from pre-sintered zinc (hardened-hardened) zircon, it has maximum resistance and strength and longevity.
4)Composite (nano technology)
These types of composites (plastic filling material), are more aesthetic can be easily polished, have a tooth-like appearance, are more durable and resistant to breakage or discoloration. Used for aesthetic filling of the first teeth, veneers (composite laminate) as well as all other works. These are layered imitating the structure of the tooth and offer maximum aesthetics.
