Beauty of an individual lies in their smile perfected by the full set of teeth in their mouth. According to modern thinking, people having clean and perfect number of teeth simply indicates that the person is in complete health. Having a missing tooth in one’s mouth leads to lack of confidence and difficulty to face the public.
Another concern is that people want to have their artificial teeth in place without being appreciated that it’s prosthesis. In earlier days there used to be only metal crowns and porcelain fused to metal crowns in place of their natural tooth to serve the purpose.
Dentistry has advanced to a greater extent contributing metal free crowns as prostheses. Metal-free crowns are a type of highly aesthetic restorations entirely made of ceramic. They can imitate natural characteristics of teeth, transmitting light like natural teeth. Although mechanical properties of Metal-free crowns are similar to those of metal ceramic crowns, their advantages are far more numerous in terms of compressive strength and aesthetics. In case of metal ceramic crown the only drawback is that over a period of years when the gums have receded, metal hue can be visible in broad daylight which is definitely not so appealing especially in case of front teeth.
Metal-free crowns are made of zirconium or lithium-disilicate ceramic. Crowns made of zirconium has exquisite mechanical properties. This white material is one of the most solid ones.
To conclude, metal ceramic crowns or even full metal crowns are no less in their functionality compared to Zirconia crowns. As the technology improves, dentistry is jumping heights for satisfaction of people.
