METAL-FREE AND PORCELAIN-FUSED-TO-METALL DENTAL CROWNS AND DENTAL BRIDGES

WHAT IS A DENTAL CROWN?

A dental crown is a fixed and personalized dental prosthesis prepared by a dental laboratory and installed by your general dentist. It has the outer shape of a natural tooth and serves to replace the original crown of your tooth. It fits on the stem of your original tooth or the dental implant abutment like a hat, covering and sealing it all around right up to the gum. Installing a dental crown can restore a tooth that is too damaged and can not be treated with a simple dental reconstruction such as a filling. If the tooth is not too damaged the installation of a dental veneer is also a possibility.

When do you need a dental crown?

  • To restore a decayed or broken tooth fot the crown completely covers the damaged tooth  

  • To support and protect a weakened tooth due to a large filling when there isn't enough left of the original tooth

  • To restore a discolored tooth after a root canal treatment, when the pulp of the tooth is removed and the tooth is no longer considered alive, it becomes darker, grayish with time

  • To reconstruct a deformed tooth, which can be the result of an accident or a dental malformation like cases of size, shape and structure defects

  • To restore chewing ability by aligning the teeth on both jaws

  • For aesthetic reasons to enhance appearance of your smile by restoring the normal size, shape, color and function of the teeth

  • To cap a dental implant

The dentist prepares a damaged tooth by trimming it to a size which allows the placement of the dental crown. The tooth, as a result, loses about half of its size. During the preparation for the installation of a dental crown the removal of the outer protective layer of the original tooth often results in the need for a root canal treatment of the tooth.

Types of dental crowns

The first stay for all our patients starts with a thorough examination in Hungary, where our dentist will explain the possibilities in your specific case and will formulate your personalized comprehensive treatment plan in accordance with your expectations. If the right solution for you is a dental crown or dental bridge, you have a choice of one of the following types. They are different in the materials used for the manufacturing, but it also makes a difference whether the crown is to be placed on an incisor or a molar. Aesthetics can also influence your decision as well as your budget for the dental rehabilitation.

Porcelain-fused-to-metal dental crowns

The porcelain-fused-to-metal dental crown is the traditional dental crown that has been used most during the last decades. It consists of a metal structure masked with a layer of porcelain reproducing the appearance of the original tooth. Your porcelain-fused-to-metal dental crown will be both resistant due to the metallic structure and will be aesthetic at the same time due to the outer porcelain layer. This crown is documented to be a lasting solution, it is a good value for money.

The external porcelain layer, which is translucent like our tooth, lets some of the light pass through towards the inner layer of the crown. The metal frame on the inside, however reflects some of the light giving a shadow effect to the dental crown. For this reason, it is not recommended for the front teeth. This effect exists also if the porcelain-fused-to-metal crown is placed on a molar, but since that's in the darker part of our mouth, it is a compromise that can be accepted in change for this reliable and affordable method.

The presence of metals, the material of the framework of the crown, can cause an allergic reaction. If you want a dental crown without any compromise, without the risk of allergy, you have to opt for metal-free crowns, such as all-ceramic dental crowns or zirconia dental crowns. This is also the case if you already have an allergy to metal or if you are allergic to several factors.

All-porcelain dental crowns

The all-porcelain dental crowns, often called full porcelain dental crowns are very high quality dental prosthesis. Porcelain is very similar to the enamel on a natural tooth so the all-porcelain dental crowns are more aesthetic than metal-ceramic crowns, it is one of their main advantage. It is a metal-free dental crown, made entirely of porcelain, which is a high quality dental ceramic. Ceramic is a fully biocompatible material. It does not present any risk of allergy, which means that the all-porcelain dental crown perfectly replaces a natural tooth. If you choose ceramic crowns made by our digital dental laboratory, no one will notice that your teeth are not natural.

The ceramic crown is however contraindicated in cases of abnormal contact between the upper and lower teeth. Porcelain is, in fact, more fragile than metals, and can break, chip off or be damaged more easily. Repeated contact with other teeth should be avoided. It is too fragile to resist pressure during chewing, so it is not recommended to use it for the back teeth. It is mainly used for the replacement of the front teeth.

Zirconia dental crowns

We can differentiate between two main types of Zirconia dental crowns. These are the all-Zirconia dental crowns, also called the full Zirconia dental crowns, and the porcelain fused-to-Zirconia dental crowns.

The material Zirconia which is zirconium oxide is the optimum material of present day restorative dentistry thanks to its exceptional properties. A Zirconia crown is lighter and at the same time stronger than a porcelain-fused-to-metal crown or a porcelain crown, it is however more rigid as well than the metal based crown. Zirconia is a material that is completely biocompatible with the human organism, very aesthetic and gives a natural appearance even without the porcelain layer. Zirconia crowns are more durable than the others, hence it is ideal for aesthetic restoration purposes. The smooth surface of a Zirconia dental crown reduces plaque accumulation. The Zirconia crown is available in several shades.

The preparation of a Zirconia crown is made with great precision with the use of the CAD / CAM (Computer Aided Design / Computer Aided Manufacturing) technique to have perfect results. The crown or the dental bridge is manufactured by a computer-controlled milling machine without manual intervention by the dental laboratory technician. This dental prosthesis is probably the most long-term solution of all the options in most cases. Moreover, thanks to the modern technology, all prostheses are not only prepared more precisely, but also in much less time than by traditional methods. The software used to design and make Zirconia crowns and bridges with the CAD / CAM technique even allows you to design the smile you've always dreamed of.

A Zirconia dental crown is a good choice to cap aesthetically any gray teeth you might have. Dentists advise Zirconia dental crowns and Zirconia dental bridges because it is not as light-transparent as porcelain, so the gray color of the titanium abutments of dental implants can be efficiently covered and blocked. Zirconia dental crowns and bridges are the optimal solution after having dental implants placed.

Dental bridges

A crown is a dental prosthesis, an artificial tooth to replace the original. In cases where there are several damaged teeth or missing teeth next to each other, the dentist will place a dental bridge which is a series of connected dental crowns. This dental bridge is normally placed on two pillars, which may be 2 trimmed teeth, each at the end position of the part to be restored, or of course it can be the abutment of a dental implant. As explained above, a Zirconia dental bridge is the best solution for caping dental implants because of the special translucency of Zirconia. It is perfect to hide the grey color of the titanium abutments.

The required size of a dental bridge also determines the choice of material. The properties of porcelain do not allow the use of an all-porcelain dental bridge of more than 3 elements since the stability and the resistance of the bridge can only be guaranteed up to 3 elements. If 4 elements are needed, it is necessary to choose either a porcelain-fused-to-metal bridge or a Zirconia dental bridge, the latter being the more aesthetic and more durable solution.

The higher cost of a Zirconia bridge will return by its long-term usage without any risk of allergic reaction and will provide the aesthetics that will make you smile. The longer warranty associated with Zirconia crowns and bridges is another reason to choose this option. For the front teeth, where aesthetics could be your primary concern, the use of an all-porcelain crown or bridge is a fair choice to be considered. In case of any uncertainty, our dentist will give you all the necessary professional advice so the best choice can be made in your personal case.
