A crown is a cap that is designed to cover the entire damaged tooth. It not only provides support and strength to the tooth but is also used to improve the shape and appearance of your smile. It can also be cemented to an implant and provides the necessary structure and function. Today all porcelain crowns are considered the most beautiful crown that a tooth can get. Porcelain is a kind of ceramic built by firing and stacking and ceramic refers to porcelain only.
Pure porcelain is the only crown which gives the desired translucent look to the tooth. They are translucent in color and generally, their color is influenced by the tooth under them.
Uses of crown
If your tooth is damaged but not lost, a crown can be used to restore its shape, appearance and function. You may need a crown if you have a root canal, a large filling in a tooth or a broken tooth.
A crown, also called a cap, is a hollow, artificial tooth used to cover a damaged or decayed tooth. The crown restores the tooth and protects it from further damage. Crowns can also be used to cover a discoloured or misshapen tooth. A tooth that has been fixed with a crown looks and works very much like a natural tooth.
Advantages of the best porcelain crowns in Tehran
Porcelain crowns can be matched to the color of your natural teeth. Crowns can also be made from cast gold, base metal, and porcelain fused to metal. These materials are stronger than porcelain and may be recommended for molars. Usually, people prefer porcelain bonded with metal as it is both aesthetically pleasing and durable.
- Transparent and true to nature and aesthetically appealing
- No allergic reactions and highly biocompatible and reduced sensitivity
- Alignment and form correction is possible
- Ideally suitable for patients who have reduced space inside their mouth and are looking for that natural looking tooth
Types of all porcelain crowns in Tehran
There are various types of these crowns and they are mentioned below.
E Max – layered
E Max is the newest type of cosmetic material used for porcelain dental crowns and porcelain veneers. Just like conventional porcelain fused to metal crowns, they are made with two layers. There is a strong and durable supporting layer called the coping. A lifelike top layer is applied on top of the coping by an ceramic artist to match the restoration to the natural teeth.
Emax is the preferred ceramic system for anterior teeth. It is both bio-compatible and has the long term wear pattern like that of enamel. Emax can be used for minimally prepared veneers or crowns as thin as 0.2mm. It makes beautiful restorations that are 2.5 to 3 times stronger than the other glass-ceramic systems used today.
E Max – Monolithic Porcelain crowns
E Max Monolithic is a one layer system using only the coping layer. The E Max coping is beautiful on its own. It does not use the weak top layer and is more resistant to chipping.
Usually it is the custom top layer of ceramic that is the weak link with all-porcelain systems. E Max monolithic is a good choice to create porcelain crowns suitable for nighttime bruxers or tooth grinders.
Zirconium
Zirconium crowns are considered to be the ultimate in strength. This ceramic is used to make one or two layer restorations. The coping is extremely strong but is opaque and ugly. Two layer versions can be made to be attractive but are no stronger than E Max layered.
The base coping is milled and has a weaker baked on top layer. This top layer is used to make the restoration attractive and lifelike. The thicker the top layer the less you see of the coping underneath. More drilling allows the veneer to mask the opaque bright white coping.
Empress Porcelain Crowns
Empress can be made with the appearance of natural teeth. Due to lack of strength, Empress is losing popularity. This ceramic has two layers, a medium strength coping, and a weaker baked on top layer. The top glass layer is hand stacked and fired onto the pressed base coping beneath. Blessed with only modest strength, Empress should never be used in grinders.
Cerec and Sirona | Trading Quality for Speed
Cerec and Sirona milling technology is growing in market share. The brand names Cerec and Sirona are “in the dental office” CAD milling machines.
Onlays or caps are milled from monolithic ceramic blocks. These tooth shaped caps can be created in one visit. They can only be customized by using surface stains that wear off over time.
The popularity of these low priced milling machines is growing in average dental offices. There are three benefits that motivate dentists to use this inferior system. Cutting out the lab technician fees creates a financial incentive. The technology appears to be impressive to the patient. Temporary crowns are not needed.
Porcelain Crowns Vs Fused Metal Crowns
Porcelain fused to gold or other metals can provide a similar aesthetically pleasing natural look as porcelain crowns; gold-based crowns are layered with a porcelain coating which gives the crown a more natural appearance since the gold base under the porcelain isn’t visible. You should know that while this type of crown is very strong and durable, it can chip and expose the metal underneath. While there are reasons to use this type of crown, it may often be a better choice to use a more standard porcelain crown.
Porcelain Crowns Vs Gold Crowns
Gold crowns are often recommended for your molars or the teeth in the back of your mouth, due to the stronger bite and grinding forces of those teeth.
They are also used when the decay or breakdown of the tooth or teeth being capped is so severe that porcelain or other types of dental crowns won’t work. While gold dental crowns are extremely strong, they can be quite visible when you smile or laugh, and of course the metal doesn’t exactly match the look of your natural teeth. Like other kinds of dental crowns, gold crowns have similar characteristics to your natural teeth, meaning they will wear down over the years and may need to be replaced.
If you have gold dental crowns (or any other type of dental crown), you should have them checked regular for signs of wear, chipping, or other issues.
Porcelain Crowns Vs Zirconia Crowns
Zirconia or zirconium metal crowns are another common option. Zirconia crowns are made of an opaque material which looks similar to porcelain, although it is thought that sometimes thought that they don’t look as natural as porcelain does. Porcelain and zirconium crowns are used and applied in fundamentally the same way using similar techniques to craft and place the crowns.
Zirconia crowns became popular several decades ago and they contain approximately ninety percent zirconium oxide, which does lend them some strength and resistance to chipping, cracking, and discolouration. They do provide a somewhat natural appearance, but lack the flexibility and customizability of porcelain crowns.
Porcelain Crowns Vs Veneers
Both porcelain crowns and veneers are used to improve the appearance of your teeth, especially if you have damage or discolouration on your front or more visible teeth.
However, veneers are generally used for more aesthetic improvement since they are made from super thin porcelain and only bonded to the front of the tooth – they don’t necessarily involve strengthening the tooth.
Rather, veneers just improve the appearance and shape while porcelain crowns encase the entire tooth and help to protect damaged teeth in addition to helping create a better aesthetic for your smile.
You should always talk with your dentist about your options for improving the health, strength, and appearance of your teeth. They will be able to advise you as to the best options for improving, strengthening and otherwise making your teeth the best they can be.
Placement of the best porcelain dental crown in Tehran
Sometimes when you need a crown, you may also need a root canal treatment; however, this is not always necessary. Root canal treatment is only required when the cavity is deep and extends to the pulp where the nerve is located.
Since crowns are used when large areas of the tooth become decayed or damaged, dentist may need to insert a post-and-core foundation into the tooth. To prepare the tooth for a crown, your dentist will file down the tooth to accommodate the prosthetic. If you have selected an all-metal crown, less of the tooth surface needs to be eroded as these crowns are thinner than porcelain-based ones.
Your dentist will then isolate the tooth away from the gums and other teeth. He will make an impression of your tooth using a putty-like material, which sets into shape within five minutes. Alternatively, dentists may also use digital technology to take impressions for the crown.
These impressions are then sent to a laboratory where the crown is fabricated. While it is being made, we will place a temporary crown on your tooth. The temporary crown is fixed in place by weak cement which allows dentist to remove it easily. Once the permanent crown has been made, dentist will remove your temporary crown and test the permanent crown. Sometimes the crown needs some small adjustments and polishing. Once it is completely ready, it is fitted into place.
HOW LONG DO CROWNS LAST?
The average lifespan of a crown is usually 15 years, although they can last much longer if they are taken care of properly. In some cases, the crown remains fine, but the tooth on which it is fitted develops a cavity. Brushing and flossing regularly can help prevent plaque buildup and make your crown last longer.
Are Dental Crowns or Porcelain Crowns Painful?
Not with an experienced dentist who has successfully placed many porcelain and dental crowns! You will be under local anesthesia and medicated while your tooth or teeth are prepped for the crown and when the crowns are applied.
Once the first appointment is over and the temporary crowns are placed, you may feel some sensitivity in your gums and around the non-permanent crown.
Upon the placement of the permanent crown you may feel some discomfort (that’s usually described as a small pinch) but the procedure will be performed under local anesthetics and topical numbing agents will be applied as well.
After the placement of the permanent crown, you may have some soreness and you will need to stick to soft foods for a while after the crowns are installed, but there should not be any significant or lingering pain.
What To Expect After a Porcelain Crown Procedure
After you get your porcelain crowns installed in Tehran and your mouth is healed, you can proceed to eat and drink as you normally do, along with brushing and flossing your crown the same way you take care of the rest of your natural teeth.
You may want to switch to a toothpaste meant for sensitive teeth for at least a while after the crown procedure as well. You should be aware that it may take a while to get used to the feeling of the crown in your mouth; if the feeling persists for several days or a week you may need to visit your dentist for an adjustment to ensure that the new crown fits your bite perfectly.
How Do You Care For Dental Crowns?
While porcelain crowns and other types of dental crowns cannot get cavities, you still need to ensure your upgraded teeth are properly cared for, including regular brushing and flossing (the same way you care for your other natural teeth).
You can still get cavities and tooth decay underneath a porcelain or other type of crown if you do not practice proper dental hygiene.
Keep in mind that crowns can still stain, especially if you regularly consume things like coffee and red wine that tend to stain natural teeth as well.
Teeth whitening products do not work on caps or crowns, so if you want to whiten your natural teeth, you may need to discuss that with your dentist and possible replace or update your crown with white teeth caps.
How much do porcelain crowns cost in Tehran?
Costs vary with the time, expertise, and materials used. Early in a dentist’s career, he/she will choose the quality level that they want to practice at. The ceramist quality level and cost will match. Typically, a high end dentist will take more time, have better technique, and use better materials. They will work with a more expensive dental laboratory. Full porcelain crowns are more expensive than metal or porcealin fused to metal crowns. However their natural look and durability compensate for the higher price.
