Indication for Full Coverage Crowns
A dental crown is a type of fixed prosthesis used to restore the structure of a tooth or replace a missing tooth — in which case it is fitted over a dental implant. In addition, it has the advantage of being very resistant and restoring the functionality and aesthetics of the patient's smile and can be made from different materials.
What is a full-coverage dental crown?
The tooth is divided into the root (the part below the gum) and the crown (the part above the gum, or the visible part of the tooth). So, when we talk about a fixed prosthesis treatment that uses a dental crown, it means that an artificial version will replace the natural one.
In this way, the prosthesis can be placed to protect a weakened tooth, cover one that has lost part of its structure or even fill a gap. It is, therefore, an option for you to smile safely again and be able to chew and speak normally, as your jaw will be complete again.
When is the placement of a full-coverage crown recommended?
Treatment with dental crowns is widely used in dental clinics, as there are several indications for their placement, such as:
- after a large restoration in a cavity treatment, for example, when little tooth structure remains;
- restoration of a tooth that has suffered a fracture;
- protection of a weakened tooth;
- dental implant treatment, in which the piece is placed on top of the titanium post;
- coverage of a tooth that has undergone root canal treatment;
- connection of a prosthesis;
- covering of a discolored or misshapen tooth.
What are the main materials used?
When it is recommended to place a crown, many patients have doubts about which material to use. The tip is to talk to your dentist, evaluating the pros and cons of each option.
Ceramics
These are pieces made of porcelain, offering excellent resistance and aesthetic results, as their color closely resembles that of a natural tooth. To ensure they are placed and fit perfectly, it may be necessary to wear down the tooth structure a little. Ceramic may not be the most suitable material for people who suffer from bruxism, that is, have the habit of grinding their teeth, especially while sleeping.
Metal ceramics
For those who need more resistance in the dental crown but do not want to give up the aesthetic advantages of porcelain, one option is the metal-ceramic piece.
In this case, the porcelain is reinforced with a metal structure, ensuring a stronger and more durable prosthesis. or its placement, wear on the tooth structure is moderate.
Resin
The color of crowns made of resin also resembles the natural color of teeth, but it is a material that can be quickly damaged.
Base metal alloy
There are also pieces made of a metal alloy. They provide high resistance to the tooth and do not require much wear on the tooth structure for their placement. However, they have a major aesthetic disadvantage, as they have a color that stands out in the smile, compromising the appearance.
Acrylic
This component is often used to remodel yellowed teeth or teeth with serious impacts. It is an easy and cheap material to produce. This impacts the value of the crown, which is more affordable. Another advantage is the aesthetic result, which is similar to natural teeth due to the appearance of acrylic. However, the resistance is not as high.
Gold
This valuable metal can also be used to apply crowns. You've probably seen this in pirate movies. In real life, it provides a better fit to the gums than other materials and is quite resistant. Since its color cannot be changed, it draws a lot of attention to the smile, in addition to being expensive.
Zirconia
This component has advantages such as resistance and satisfactory aesthetic results. Since the zirconia crown does not contain metal, light can pass through it normally, giving it a more natural appearance. It also does not suffer from the appearance of stains.
