ALL CROWNS ARE GENARALLY MADE IN DENTAL LABORATORY WHERE IMPRESSION IS SENT TAKEN BY DENTIST.

TYPES OF CROWN:
1.ALL CERAMIC CROWN.
This are made of ceramic looks much like natural tooth structure mainly ued on anterior teeth for cosmetic reasons ,smile designing .are not of great strength when compared to metal or metal fused to ceramic crowns.There is a growing demand world-wide for cosmetic dentistry.

Anterior crowns and bridges are now being made from all ceramic materials such as Alumina, Zirconia and glass composites. These materials, are extremely strong, and allow light to refract through them offering a restoration of much higher vitality compared to a conventional porcelain bonded to metal crown . Three types or methods will be described below you can compare all ceramic crown with metal fused to ceramic crowns note the translucency

 

2.CERAMIC/PORCELAIN FUSED TO METAL CROWN.
METAL can be precious or non precious .
The majority of restorations within most practices is porcelain fused to either precious or non precious metal. It has been tried and tested for many years.
This product enables the technician to achieve high aesthetic results every time and a good match to adjacent dentition.
There are also lower fusing porcelains, which are slightly kinder to opposing dentition such as "Duceragold". "Duceragold" porcelain is used with a yellow bonding gold so a softer, warmer result can be achieved.

	CAD/CAM Titanium Framework	Porcelain & Gold

CAD/CAM Titanium Framework
Titanium are also used against precious alloy for crown Titanium allows an X-ray to detect if secondary caries is present beneath the restoration whereas precious alloy prevents detection of secondary caries.

Biocompatibility - Titanium is a fully proven material both intra orally as well as for more complex applications such as knee and hip replacements. This is not only substantially cheaper than precious alloy but also there will be no price fluctuations as is the case with precious alloy In other words Titanium’s suitability to replace precious alloy for crowns and bridges cannot be questioned!

3.WHITE METAL CROWN:
This are made up of nickel chrome cobalt alloy mainly looks like steel .this generally cheaper crowns used mainly in posterior tooth

4.METAL FUSED TO ACRYLIC CROWN:
This are nickel chrome cobalt alloy crown fused to acrylic resin to impart esthetic result .this are also generally cheaper compared to ceramic crowns .when affordibility is the reason you can go for this crown .

5.GOLD CROWN
The "full gold crown" is an excellent restoration for POSTERIORS. Gold stands alone as being one of the best restorative materials. Gold's disadvantage is its color, which distracts from a natural looking smile. That is why it is best used in areas of the mouth that are not seen in a full smile.

 

6.COMPOSITE CROWNS
Composites crowns have been formulated to withstand tensile and compressive stresses, abrasion and attrition, and are less abrasive to the opposing dentition than ceramics.this are new generation material used for dental restoration .


7.CAD/CAM DENTAL CROWNS:
Benchmark has invested in the leading CAD/CAM and system designed for use by the laboratory thereby allowing us to produce innovative designs to the highest sustainable quality.
CAD/CAM combines an optical impression technique with a computer-driven fabrication module in a single mobile workstation. The restorations are machined from industrially preformed blocks of either Alumina, Zirconia and Glass composite depending upon the application.

Our systems enable the clinician to offer patients a wide choice of restorations such as
a. Alumina and zirconia crowns, and up to 6 unit zirconia bridges whereas it is not possible to produce large     span bridge work from conventional systems.
b. Finished posterior crowns from glass composite.
