Dental crown.

 

 

Is a cap that is placed over a tooth and held in place by dental adhesive or cement, Crowns and fixed bridges are used to treat problems of decay, fractured teeth, malocclusion and to protect teeth which have had root canal treatment, or large fillings. They can also be used to change tooth color and shape.

 

Crowns are used for several reasons:

• As a protective cover for badly decayed teeth or fractured teeth

• As a permanent restoration for teeth with large fillings

• To correct minor problems in natural teeth like spacing and irregular shape or severe discolouration

 

Procedure.

When we have decided to go ahead with a full crown restoration, we will set aside 2-3

appointments for the entire process. Although the majority of crowning treatments

are completed in two visits, there is sometimes a need for a third visit to ensure its

proper fit.

On the first visit, the tooth will be reshaped by filing down the tooth so that the crown

can be placed over it. You will be given a local anaesthetic before this part of the

procedure so that no discomfort is experienced. Once the tooth has been reshaped, a

mold will be taken of that tooth and the surrounding teeth. This mold will be sent to a

dental lab so that your new crown can be made to fit the spot created for it and looks similar to the surrounding teeth. 

During your second visit to the office, we will proceed with the placement of your final restoration. This crown will be fitted comfortably into the mouth. We will make every effort to ensure that the new tooth feels exactly like one of your natural teeth. The final step in the process is to cement the crown into your mouth, leaving you with a beautifully restored smile.

 

What are types of Crowns?

 

Metal crowns.

In the middle of the last century, when other suitable prosthetic material did not exist, these

bits are used very widely. Metal crowns reliable and strong, but they have two major drawbacks.

First, look these crowns are not aesthetically pleasing. Secondly, metal allergy in humans is

often enough. Installing a large number of bits is contraindicated.

 

Gold crowns.

Gold - a material durable, easy post treatment and does not oxidize. These bits previously used no less frequently than metal, although the cost of such crowns have always been higher. The main drawback of gold crowns - apparently they are highly visible.

 

Metal-ceramic crowns.

For several decades, these crowns are the most common in orthopedics. These crowns are

very strong, but at the expense of spraying ceramic layer, to select the color of the tooth

enamel, they are practically invisible.

 

Ceramic crowns.

Used in orthopedics is not so long ago. The main advantage - high strength and looks completely identical with natural teeth. Of course, the cost of such crowns higher than cermet, however, when it comes to prosthetics front teeth, the dentists generally recommend installing this kind of crowns.

 

Zirconia crowns.

These bits are not made entirely of zirconium, ie zirconium frame runs only, the

deposition is made of ceramics. These crowns - a new orthopedics. At a cost of hard

to call cheap, but they are even more durable than metal-and thus the same aesthetic

ideal as a crown made of ceramic.

 

Plastic crowns.

It is clear that plastic - it is not the most durable material, so the data bits are used only as temporary. There are still bits of metalloplastmassy but in dentistry, they also are not widely used because of the rather limited lifespan.

 

Dental Bridges.

A bridge (also known as a fixed partial denture) is planned when one or more teeth are

missing and there are healthy teeth on both sides of the open space. With proper care,

your new bridge will increase your overall health and instill confidence for years to come. 

The materials used for dental bridges is the same as for dental crowns.
