Why is it necessary to place a post and core to make a dental crown?

The post and core is an important part for installing a prosthetic crown to replace a tooth that has been badly destroyed, usually as a result of decay or fractures. In cases where it is possible to preserve the root with root canal treatment, the core is installed inside the root to support the prosthetic crown.

The core is the internal reinforcement part of a dental crown

This is an important stage in providing support and strength to the porcelain dental crown. See more about dental core materials. If the crown were installed without a core, the prosthesis would probably not be able to withstand the masticatory effort and consequently its duration would be shorter.

See also this article on our blog which talks a little more about root canal treatment, core and porcelain crown. Today, the reinforcement core (dental post) can be made from various types of materials: from metal to zirconia, fiberglass and carbon fiber.

The choice of material depends on a number of factors, such as the location in the dental arch and the masticatory load that the crown will be subjected to.

The metal core is considered more resistant (especially suitable for the most hidden and used area of the arch), while zirconia is considered more aesthetic because it is white (suitable for the most visible area, i.e. the front of the arch).

The prosthetic crown can be made from two different materials: resin (plastic with a metal core) or porcelain (with a metal or aesthetic core). Porcelain is more resistant and aesthetic than resin.

How treatment is carried out:

In some cases, root canal treatment is performed to preserve the root;
The root and tooth are prepared to receive the core;
When made of metal, the impression is taken directly inside the root;
When in zirconia, the post is cemented into the root;
A core mold is taken to prepare the prosthetic crown. At ImplArt, this mold can be made conventionally (with putty) or digitally using intraoral scanners;
The crown is installed on the core;
The duration of the procedure varies, as it depends on the complexity of each case. For some people it can be carried out in a Day Clinic.

Advantages of the technique:

The dental crown restores chewing ability as well as the aesthetics of the smile;
The appearance of this type of prosthesis is very similar to natural teeth, so it is indistinguishable when fitted;
Your smile will be beautiful and complete again, free of unsightly spots such as cavities, metal restorations, absences, etc;
The roots are protected and healthy;

dental core and crown — Why is it necessary to place a post and core to make a dental crown?

Dentures are very durable, but they may need to be replaced after a few years. This need is verified during regular visits to the dentist’s office.

In cases where teeth are weakened and it is no longer possible to rebuild the tooth with a crown, dental implants are recommended. If you have any questions, please make an appointment or contact us. We’ll be happy to help you.

Porcelain crown for implants – Day Clinic

What is a porcelain crown on a dental implant?

The placement of a porcelain implant crown is one of the procedures that ImplArt Odontologia can carry out with the convenience and agility of Day Clinic Dentistry in São Paulo.

A porcelain crown is a type of fixed prosthesis with a shape, color and functionality very close to that of a natural tooth, to be fitted over a dental implant. The dental implant is a titanium pin that replaces the root of a lost tooth and supports the prosthesis.

The porcelain crown on dental implant is certainly capable of restoring a beautiful smile and chewing safety for people who have lost one or more teeth, including the root, for some reason. Because it is made from state-of-the-art materials, the porcelain dental implant crown is highly aesthetic, resistant and durable.

ImplArt Odontologia uses the metal-free technique to make porcelain crowns. The advantage of this technique is that the internal structure of the crown is reinforced with zirconia. It is a white material, therefore free of metals and invisible inside the prosthesis, which gives the prosthesis a much more aesthetic result and no dark spots. These materials are also very resistant.

How is the porcelain implant crown made in the Day Clinic?

At ImplArt, the design of the porcelain implant crown is computerized and executed on 3D printers. The design of crowns is completely personalized for each person, quickly and conveniently. This is thanks to our complete structure, which includes a multi-specialized team and our own digital prosthetics laboratory equipped with computerized systems such as Cerec Sirona and 3Shape.

More translucent and resistant cubic zirconia crowns

Translucent cubic zirconia is an evolution of conventional dental zirconia. Dental zirconia is increasingly being used as a material for making a dental crown or even for a fixed prosthesis on dental implants. Translucent Zirconia has certainly come to revolutionize the way dental prostheses are made, since it uses modern computer graphics resources to design the prostheses, and modern 3D milling machines to sculpt them. This makes treatment faster and more comfortable for the patient.

In addition, Zirconia is the most resistant material compared to other types of crowns and allows for results with a high degree of naturalness, being the most similar to the appearance of natural teeth.

Zirconia can also be used on implants, protocol prostheses and partial prostheses.

Why is dental zirconia an excellent material?

First and foremost, one of the greatest advantages of the Pure Zirconia dental crown is its strength and durability. In addition, its modern execution method, which doesn’t require the old mass moldings and only uses a 3D scanner, makes the treatment much more comfortable for the patient. It is therefore an excellent option for those who want metal-free treatment, a situation that is highly valued today with biological dentistry.

These zirconia structures can be used both for implant prostheses, types of crowns on implants and for crowns on natural teeth. One of the pioneering companies in the development of durable and aesthetic zirconia dental prostheses is the Austrian company AmannGirrbach. Now it is introducing a new type of dental ceramic: Zolid FX translucent cubic zirconia.

It is a fully biocompatible material used to make first-rate prosthetic crowns, not only single-unit, but also bridges of up to 3 units. The main characteristics of Zolid FX are its super-high translucency, high strength and long-term stability.

It is therefore a strong alternative to the already established lithium disilicate (glass ceramic), and can therefore be especially suitable for cases that require high porcelain crown strength. Cubic zirconia crowns can be installed both anteriorly with excellent aesthetics and posteriorly. They can also be used in dental implant treatment.

What is the manufacturing process like?

The Zolid FX cubic zirconia crown is made using computerized CAD/CAM equipment. It starts with milling the rough block on a 3D printer to the shape of the tooth. The zirconia crown is finished with the manual addition of colors and shading so that the crown has natural visual characteristics, like the neighboring teeth. The pure zirconia crown is super aesthetic and is up to 10 times stronger than ordinary (feldspatica) porcelain.

Translucent cubic zirconia crowns are suitable for bruxism patients due to their resistance

Bruxism is an oral functional disorder characterized by involuntary grinding or clenching of the teeth. The excessive force generated by bruxism can cause not only muscle and joint pain in simpler cases, but also the destruction of part of the tissues (bone and gum), enamel or the structure of the dental crown in more advanced cases.

It is important to remember that before your permanent porcelain crown is made, you will receive a temporary crown. This is used to check the aesthetics and chewability of the permanent crown.

However, bruxism can be just as damaging to the structures of prosthetic crowns made from certain materials. For this reason, there has always been a need to develop prostheses with increasingly resistant and stable materials, and at the same time aesthetic (without metals in the structure).

The translucency and strength characteristics of Zolid FX are fundamental to making the prosthetic crown very comparable to natural teeth. The result is extremely aesthetic crowns and restorations with high strength and long-term stability.

ImplArt Dental Clinic only works with materials of the highest quality, developed by serious companies. For example, AmannGirrbach, which only introduces materials and equipment to the market after carrying out numerous tests and research.
