Dental implants are artificial teeth which are placed as an alternative to partial or complete crown in your mouth. When be placed and properly integrated into the bone, implants may then be fitted with a number of different prostheses.
The Cost of dental Crowns
Crowns have a relatively much higher fee when compared to direct tooth. As mentioned above, the higher costs are associated with the materials and compounds contained in your crown. The cost of a crown may be vary in different countries. However, a dental crown must be cheaper in Asia country than in North America and Europe in most cases. In general, a porcelain dental crown may cost about 20% more than full gold crowns, and the time-consuming processes of the dental operation is also an important reason for this comparison.
Types and materials
There are many different methods of crown fabrication contribute the difference of price of a crown. We can roughly summarize some common material which made a crown and shows the difference of cost on the market.
Full gold crown
Although referred to as a gold crown, this type of crown is actually composed of many different types of elements, including but not limited to gold, platinum, palladium, silver, copper and tin.
Porcelain-fused-to-metal (PFM) crowns consist of a metal coping that is for a full gold crown. The Porcelain fused-to-metal crowns may conform to the proper dimensions of the restored tooth except for the facial surface of the tooth.
Besides to metal and porcelain, there are some more crowns have been developed to fill the different needs of patients with the improvement of dental technology.
new so called "all-ceramic crown" with glass to produce what was then thought to be a superior product.
Owned by Nobel Biocare, is a CAD/CAM based method which produces a crown by overlaying a very durable ceramic coping of either alumina or zirconia.
A specially designed ceramic pressed into the mold, as though the final all-ceramic restoration has been "cast." The Empress is also used for dental veneers.
The current leader in CAD/CAM crown manufacturing in the Northern is CEREC. The CEREC method of fabricating all-ceramic restorations is by computer system to generate a three dimensional image of teeth. After selecting the proper features and making various decisions on the computerized model, the dentist directs the computer to send the information to the computer system which will mill the restoration from to match the patient's tooth.
