Everything related to dental crown
Dental crown is one of the most common methods of tooth reconstruction. The cover is actually a cap similar to the crown of the tooth, which is supposed to play a role in chewing food instead of the crown of the tooth, that is why it can also be called an artificial crown.
The crown is the white part of the tooth that protrudes from the gum and you see it in the mouth. Another part smile and restore beauty to some teeth, veneers may be used. Some people believe that this treatment is painful, but we must say that no, the dental crown that is placed for denervated teeth does not hurt, but other cases will be painless with local anesthesia.

Dental veneers are made of different materials. Depending on the patient's needs and taste, its type is selected:
1. Coating All Metal, gold
Gold is one of the oldest dental restoration materials and has long been used as a filling or coating to restore function to teeth. Gold coating is the most resistant and strongest type of dental coating, and it is usually the most expensive type of coating in terms of cost.
In these veneers, the inner part of the veneer that is in contact with the dental tissue is made of gold and their outer layer is made of porcelain. Due to its unique properties, gold is considered the best restorative material or coating in dentistry.
There is no corrosion or discoloration in these veneers around the gums. The compatibility of gold with tooth tissue is very favorable and even improves over time with chewing pressure. These covers are considered excellent in terms of durability.
Advantages
- Very resistant to pressure and impact
- High durability and long life Compatibility with the human body without causing allergies and inflammation
Disadvantages
- High cost
- Gold color (in some cases)
2. Full ceramic coating
Ceramic coating is made in different ways. One of the latest methods of making ceramic veneers is the use of low-code digital technology, in which the design veneer is carved and made by a machine. You can choose this cover in any color you want.
Although its color can be changed according to the color of the patient's other teeth, please note that after the veneer is made and prepared, its color cannot be changed. In terms of resemblance to real teeth, ceramic veneers are the best option.
In cases where beauty is the main priority, covers that are integrally made of ceramic or porcelain create extraordinary beauty. All-ceramic veneers have a very favorable compatibility with the gums. All kinds of ceramics with high strength such as silicate and zirconia are used for these coatings. No color change or dark shade can be seen on the edges of these covers. Their durability is desirable and their beauty is extraordinary.
Among the advantages of ceramic coatings, the following can be mentioned:- High resistance against color change Compatibility with the human body without causing allergies and inflammation
- Beauty and white color
- Less resistance than metal coatings
- metal ceramic
3. Ceramic-metal coating.
Metal ceramic coating is known as PFM coating. Metal base veneers have a metal frame with a ceramic layer on top. Therefore, in terms of beauty, it is almost similar to all-ceramic coating.
The most common types of covers are those whose inner part is made of metal and their outer surface is made of porcelain. In these covers, a metal edge is usually visible behind the cover. Over time, with the analysis of the gums, it is possible for their metal edge to appear
Over time, due to corrosion, the metal edges may turn black or blue, creating a discolored appearance in the gums. In general, porcelain color in this method is less transparent than the real structure of the tooth.
The durability of these veneers is desirable if the patient's oral hygiene is very good.
Advantages of this type of covers:
- High resistance due to metal frame
- Lower wear compared to other covers

Covering steps dentist
Prescription cases of dental veneers
- All denervated teeth are prone to breaking (because the tooth becomes brittle after root denervation treatment and the flexibility of the walls is lost.) Dental veneers help the walls to resist the pressure.
- The form of the remaining walls of the tooth should be such that the filling material does not remain inside it, in this case, cover Teeth are needed.
- To make a bridge: two dental implant posts are used to replace 3 teeth, the covering is placed as a bridge between the two posts.
- Correcting the shape of the teeth: Dental veneers for the front of the mouth can straighten the teeth.
- Correcting the color of the teeth: dental veneers can make one or more discolored teeth more beautiful.
The amount of tooth sharpener for all types of dental veneers
To make any type of tooth cover, first it is necessary to shave some of the surface of the tooth and then make a molding of the shaved tooth, which is done with a much higher accuracy in the digital method instead of molding a 3D scan.
They need the most grinding (1.5 to 2 mm from all tooth surfaces)
- Zirconia crowns (Zirconia Crown)
It is necessary to shave the surface of the tooth about one millimeter.
- Full Zirconia tooth cover
They need the least amount of cutting (about 0.5 mm).
- Full metal tooth cover (Full Metal)
A tooth scraper of 0.5 mm is sufficient
continue Dental crown
The life of a dental crown depends on many factors, including:
- Personal oral and dental hygiene
- Repair quality and base tooth walls
- The quality of denervation of the root of the dental veneer
- Gum health around dental veneers
- Absence of premature chewing contacts and grinding teeth
- Complete fit of the dental veneer on the base tooth and gum
- Using the right cement to attach the dental crown
