Amazing Ceramic Dental Crowns
Ceramic Dental Crowns are tooth shaped caps that are used to cover teeth. They are made of porcelain or ceramic.
People with crowns sometimes will have a dark line between their tooth and the gum line. This is because their crown has metal on the inside and is covered by a thin layer of porcelain to look like a tooth. The dark line you can see is a thin line of metal that is between the porcelain and the gum line.
Not all crowns have metal on the insides. Crowns made with Zirconia (a white metal like substance) have a white center, but there are many types of metal-free crowns on the market including Feldspathic, Zirconia, E-Max.
In the crown illustration, you can see the difference between a metal and ceramic crown. One is more dark on the inside – thus the tooth is usually more opaque and darker hue.
What’s the best crown available?
That is an unfair question – ask yourself what the best car available is? well it depends – are you racing or carrying a big load? is it for looks or function?
The same is true for crowns – some look better, some are stronger. And it also depends on who makes them. Keep in mind when choosing a crown that the materials used to create them effects their cost — and the quality of the crown. But the technicians who make them vary in quality and attention to detail. They can be a mass produced item or a detailed one-at-a-time crown.
What Crowns does Midtown Dentistry recommend?
We recommend the following crowns on a regular basis:
The Bruxzir crown is made from solid Zirconia and is the strongest crown on the market. Just look at the hammer test to see how strong it is.
The Bruxzir crown is especially good for back teeth that are prone to breaking due to heavy chewing forces. Older type crowns can break or chip under normal use. But this crown has not broken in over three years of use on hundreds of patients. It’s just that strong.
The downside to this crown is that it only comes in several colors – and can never be made to look like a real front tooth. That is why we do not use it for front teeth.
E-Max is a lithium disilicate glass ceramic that has optimized for great looks. This is the ideal material to make crowns for front teeth. It is glued to the existing tooth and looks amazing.
The downside to this crown is only that it is weaker – so we cannot make bridges or crowns where the biting force is great- like the back teeth.
