Non-metal porcelain crowns
There are many non-metal porcelain crowns in structures such as zirconium or alumina. After the examination, your dentist decides which non-metal porcelain will be used. While zirconium teeth are preferred for posterior teeth as it provides a durable and aesthetic appearance, other non-metal porcelain structures are preferred for anterior teeth.
The durability rating of zirconium crowns is 900-1400 MPa. Metal porcelains are resistant to about 800 MPa or less. It is also common to use zirconium for 3-4 unit bridges. Since they are the same color as your teeth, you will not see gray reflections in the gum area.
Zirconium is essentially a tooth-colored infrastructure material that supports the feldspathic porcelain overlying it. Its compatibility with oral tissues is much better than the alloys used in metal-supported porcelains. At the same time, due to its chemical properties, it is not affected by oral fluids and does not cause any discoloration, staining or gray stripes on the gums. Even if the gums recede, it does not lose anything from its aesthetics. Because of its high durability, it can also be used in bridge construction (except very long bridges) and in back areas. Although its light transmittance is slightly less than empress and feldspathic porcelains, it reaches aesthetically satisfactory levels with the use of the right zirconium system. Zirconium supported porcelains can be used in the construction of crown bridges on implants, these features distinguish them from other all-ceramic systems.
In what cases is Zirconium porcelain applied?
Zirconium porcelains can be applied in almost every situation where metal-supported porcelain can be used but aesthetic expectation is higher.
- Tooth discolorations
- Shape and position disorders
- Ruined teeth
- Implant crowns (veneers) and short bridges
- Posterior dental crowns (veneers) and bridges
Full Ceramic (Full Porcelain) Crowns (Veneer)
Porcelains are aesthetic materials that are perfectly compatible with oral tissues and do not cause allergies. Gray discoloration is not observed at the gingival level, as they do not contain metal in them (All-ceramic crowns) made entirely of porcelain. At the same time, their light transmittance is closer to the natural tooth and they give a similar appearance to the natural tooth even under different light sources. They are perfectly biologically compatible with the gums. Both aesthetic and biologically compatible restorations are obtained by using different reinforced varieties of all-ceramic crowns according to the region to be used in the mouth.
Do Zirconium Crowns stain? How should zirconium crowns be protected and cared for?
Zirconium crowns do not show serious discoloration as long as oral care is given. However, in patients with excessive smoking, tea and coffee consumption and who do not pay attention to oral hygiene, staining of natural teeth may occur.
Zirconium coating care is the same as the cleaning procedure applied to natural teeth. What should be done in daily dental care also applies to zirconium. For the maintenance and long-term use of zirconium prostheses, correct brushing technique and dental floss 2-3 times a day will be sufficient.
Do zirconium crowns damage the tooth?
In all types of crowns, that is, the teeth to be covered, the teeth need to be fixed a little and space must be made for the prosthetic tooth to be made. Therefore, a small amount of wear is made on the teeth for zirconium prostheses, but this amount is no more than for metal-supported veneers.
Zirconium has very high fracture resistance and durability. However, it is not correct to give a certain lifespan for the prosthesis. Because the user's muscle activation, abnormal habits and nutritional habits are as effective on the life of the prosthesis as the material used.
In which cases zirconium crowns are applied:
- If your teeth have been cut beforehand,
- If you have an unaesthetic tooth alignment due to split teeth,
- If you are uncomfortable with the dark band formed by metal-supported coatings in your mouth,
- If you have teeth with intense fractures,
- If your teeth look bad with old fillings whose color, structure and texture have deteriorated,
- If there is too much material loss in your teeth that the filling cannot fill,
- If you do not prefer orthodontic treatment for your crooked and crooked teeth to be aesthetic and healthy, we design your teeth with natural white colored and healthy new crowns with our zirconium crown treatment.
Are zirconium crowns as durable as metal-supported porcelain crowns?
There are some differences between metal-supported veneer and zirconium veneer, which are two different dental veneer methods. The prominent feature of metal supported porcelain teeth; Its durability is that it can be used as a bridge in long edentulous areas.
For example, if you have more than 2 cavities and a bridge is planned, metal-backed porcelain is preferred. This is because it can maintain solid structures and resistance for a long time. In its shortest definition, zirconium is actually a white metal. It carries many features of the concept of metal as an element. Aesthetically superior and more biocompatible. In terms of natural appearance, they have a more successful appearance than porcelain teeth.
Are zirconium crowns more aesthetic than metal-supported porcelain crowns?
Zirconium dental crowns are far ahead in terms of aesthetic appearance, tissue compatibility and naturalness. Of course, it should be noted that there are many quality options for this zirconium. If planning and measurements are done well, very long bridges are difficult to break unless built. More vivid, natural results are obtained.
Metal-backed coatings are opaque. The colors are cooler and duller than zirconium crowns.
Metal bridges are used to support the ceramic on which the tooth form will be formed in metal-supported crowns. In zirconium coatings, this layer is white in color and does not create a dark reflection from the gums. It transmits light.
What is the compatibility of zirconium chromiums with gums and their relationship with porcelain crowns?
In teeth with metal crowns, problems such as color reflection from the gums occur in the long term due to gingival recession. Zirconium coating is extremely compatible with gums and can be used for many years.
Long-lasting results are achieved with well-made coatings. It is not true to say that zirconium coating is definitely longer-lasting, but it is much more suitable for gum and oral health.
