Dental Crowns

A dental crown is style of restoration that encircles or caps an entire tooth or dental implant. A common reason for a crown is to protect the tooth from a large cavity that may endanger an entire tooth. A crown is also used to make the tooth stronger and to improve the appearance of a tooth. They are ultimately very beneficial for the overall health of the tooth involved. A crown is usually adhered to the tooth using what is known as dental cement. They are made from a variety of materials.

Crowning a tooth is most often done by first preparing a dental impression of a tooth that has been prepared for crowning by a dentist. The impression is then used to construct the crown before it is inserted into the mouth during a follow up appointment. This is what is known as an indirect method of restoring teeth. It allows the dentist to work with the strong materials that are needed and use fabrication methods that take a substantial amount of time and intense heat, none of which that would be possible to do inside the patient’s mouth.

Advantages and Disadvantages of Dental Crowns
When it comes to a big decision regarding your health like whether or not to get a crown, one should always look closely at the benefits of the procedure versus the cost.

Perhaps the biggest disadvantages of a having a tooth restored with a crown is the fact that in order to prepare the tooth for the crown, most of it must be ground away. The cost for this type of indirect restoration is much more expensive than the direct restorations which are done inside the patient’s mouth.

The benefits of a dental crown include the fact that they are very durable, last a long time, and have a proven success rate as compared to other types of restorations or no treatment at all. It is usually significant damage to a tooth that makes a crown the best option and the other treatments available are not usually as effective.

Materials Used for Dental Crowns
There are a number of different techniques that a dentist uses to fabricate a crown and each technique uses a different material. Some of the techniques and materials are:

· Restorations that contain metal

o One example is a full gold crown that is made up completely of one piece of gold alloy. There are actually several different elements in this type of crown besides gold, including platinum, palladium, silver, copper, and tin.

o Another style is porcelain that is fused to metal. This gives the strength of metal and the more natural appearance of porcelain.

· Restorations without metal – Restorations that are completely ceramic are done with what is known as the chairside CAD/CAM method. A completely ceramic crown is created after taking a photographic image of the tooth and then making a 3-dimensional restoration with the use of computer technology. No impression is made of the tooth.
