In the article, we will consider how teeth are made from zirconium.
Today, such a prosthetics technique as zirconium crowns is gaining more popularity and is deservedly trusted by dentists and among their patients around the world. Despite the fact that such technology for dental restoration has appeared in the arsenal of Russian dentists only recently, we can say with confidence that zirconium crowns are today one of the most aesthetic, reliable, safe and durable methods for restoration of incisors in history as a whole. These crowns are a kind of prosthetics using only advanced technologies in combination with careful quality control at every stage of production.
What are the benefits of zirconium teeth?
pros
Patients sometimes call such crowns zirconium teeth. And this is their middle name, which reflects various benefits. In fact, as a result of the use of the material from zirconium oxide does not differ in color or shape, as well as in light reflection from the native incisors of patients. Sometimes even relatives learn about prosthetics performed only from the words of the patient himself.

This ceramic has many advantages, thanks to the bioinert materials of zirconium oxide, and, in addition, to the special manufacture of the crowns themselves. To make zirconium products, it is not enough to possess only theoretical knowledge or manual skill and a minimum number of tools.
To produce teeth from zirconia, dental laboratories should have an impressive arsenal of high-precision equipment and specific tools. Zirconium crowns are produced in the factory on special equipment, which eliminates the slightest degree of error. After all, only such a product with a margin is able to withstand the load in the region of the front and lateral teeth. Next, we consider the more advantageous aspects that distinguish zirconium material for teeth:
- The presence of absolute bioinertness and compatibility with the tissues of the human body surrounding the substitute.
- The complete absence of allergic reactions to the material of the crowns.
- The degree of colossal strength.
- Absolute identity in terms of light transmission and many color characteristics.
- Rapid rehabilitation along with the lack of sensation of the presence of a foreign body in the oral cavity.
- Full resistance to deformation and abrasion.
Thus, on the basis of all these advantages, we can safely say that the advantages of zirconium crowns are more than obvious.
Cons of such prosthetics
All people are well aware that not every medicine is suitable for everyone. The same applies to zirconium teeth. This technique has its own contraindications for use:
- A relative contraindication is pregnancy, and, as a result, such a ban is only temporary,
- The presence of certain diseases of the psyche.
- The patient develops hypertonicity of the masticatory muscles in the form of gnashing of teeth in a dream.
- The presence of pathological foci of inflammation in the maxillofacial zone.
- The occurrence of certain types of bite pathology.
- The appearance of common severe diseases of the human body.
As you can see, there are many arguments against. In fairness, it is worth noting that most of the listed prohibitions on the use of zirconium crowns are contraindications to prosthetics with any materials.
When do dentists advise making such teeth?
But are zirconia teeth better or cermets? How to decide what is best for the patient in his case? To do this, you need to understand in which situations they install zirconium materials on their teeth:
- In case of poor aesthetics of hard tooth stones, and, in addition, due to darkening of the gums around old crowns.
- The patient has an individual allergic intolerance to prosthetics methods.
- Significant tooth decay along with injuries and chips of enamel.
- Partial absence of incisors in the patient. Zirconium is installed on the front teeth very often.
- Aesthetic prosthetics on dental implants.
- The presence of congenital defects of enamel.
- Imperfect shape of natural teeth.
The use of zirconium prostheses on the front teeth
Zirconium teeth in front are set according to the same principle as on the side incisors. And the only difference is that while waiting, while a substitute is made in the dental laboratory, the attending physician offers to put a temporary plastic structure. In the field of dentistry, it is well known that zirconium crowns on the front teeth are better not to choose completely from this material, but with a frame that should be covered with a thin layer of ceramic. In this case, the patient will not receive the effect of “toilet smile”, and his teeth will look as natural as possible.
Can zirconium be placed on chewing teeth?
Chewing teeth never fall into the area of a smile, so aesthetics are not so important for them. The main characteristics that chewing cutters should have are, first of all, strength and durability. Therefore, substitutes for these teeth can be made of an alloy of base metal (if there is no allergy to the material), as well as of cermet. Optimal use of zirconium dioxide. Such products are the most durable among all non-metal prostheses. In addition, the aesthetics of the dentition will not fail the patient in any situation (even if a person laughs or yawns with his mouth wide open).
How are these crowns made?
The production of zirconium tooth crowns is a complex and multi-stage process requiring special equipment called CAD / CAM. Actually, such a procedure is a fully automated process, from the stage of scanning the model in the equipment to the acquisition of the final product from zirconium dioxide.
It is worth analyzing the most important stages of such production. After taking all the required impressions by the orthopedist, the patient’s prints are sent to the address of an authorized dental laboratory in which the working models are made. Then these models are placed in a special 3D scanner. Thanks to his help, crowns on zirconium teeth are digitized, after which they are computer-simulated. Such a computer sample is exactly reproduced in automatic milling machines from a monolithic piece of zirconium, which is baked at the factory at the factory at a huge temperature.
Thus, the future zirconium crown acquires its frame, which is subsequently lined with a layer of ceramic mass, step by step reproducing the lost dental tissue. After completing all the technical steps, the finished product is sent to the clinic.
Preparation for the installation of crowns on the teeth
In this part of the article, we will mainly consider the process of preparing for prosthetics with zirconium crowns. In this case, as in the repair of an apartment, order is required along with a solid foundation for construction. During prosthetics, a well-cured abutment along with the absence of an acute or chronic focus of inflammation and well-sealed root canals serve as such a basis. It is advisable to carry out hygienic cleaning immediately before therapy and prosthetics of the incisors. Thus, the tooth surface must be carefully cleaned and ready for therapy.
Manufacturing steps
Now you should analyze the stages of prosthetics using zirconium crowns, for which, in fact, you should definitely be prepared when going to the dentist:
- Consultation along with drawing up a detailed treatment plan, taking casts for temporary substitutes.
- The preparatory stage for the prosthetics process. In this case, most often carry out therapeutic treatment in combination with sanitation of the oral cavity.
- Performing tooth processing under the crown with the imposition of temporary analogues.
- Taking a mold, determining the color scheme of teeth.
- The stage of manufacturing prostheses in the laboratory.
- Fitting and correction of the bite along with the coordination of the overall appearance with the patient.
- Fixation of crowns on special cement, which is similar to a liquid filling and ensures complete seamlessness along the ledge near the gums.
Types of crowns of this type
Today in the world there are only two types of crowns on teeth made of zirconium dioxide. The first of them is a prosthesis made entirely of this material, and the second is a structure in which the base and ceramic coating are combined. The second variety may have the best aesthetic properties. The fact is that it is much preferable to install zirconium combined substitutes on the front teeth. In the case when it comes to the procedure for prosthetics of lateral incisors, it is recommended to use orthopedic integral constructions. In order to achieve the desired shade of artificial enamel, dental laboratory specialists tint crowns, adding shadows with shine. As a result, it takes much less time to make such a prosthesis.
Prosthetics
It is important to emphasize that dental prosthetics can not be put off until tomorrow. True, no one is safe from the loss of incisors. The reasons for this loss are many: caries along with its complications in combination with injuries, periodontitis, and many other diseases of the oral cavity.
However, the main cause of loss is tooth decay with its immediate complications. According to statistics, more than eighty percent of the inhabitants of the entire globe use prostheses. The first prosthetics in the adult period of the average patient is performed at twenty-eight to thirty years.
So there is a need for a visit to the doctor and prosthetics. Orthopedics is a branch of dentistry that studies the causes of loss of incisors, and is engaged in restoring the integrity of dentitions using prostheses of different designs. It should be noted that this procedure can in no case be postponed until later, since with the loss of even one tooth, the total load during chewing increases, which applies to the remaining incisors.
Untimely prosthetics can cause dentition, along with pathological malocclusion and diseases of the temporal and mandibular joints, and this is not to mention defects in appearance and an absolute aesthetic lack of a human smile.
If even one tooth is lost, the proportion of functional overloads of the remaining neighboring incisors is about fifteen percent, which cannot but affect the duration of their overall service. In the event that the increased load resulting from the loss of teeth falls on the moving incisors, then the magnitude of the overload increases substantially to thirty to thirty-five percent.
In modern clinics, zirconium prosthetics are carried out using the latest materials, and, in addition, technological advances that make it possible to perform orthopedic constructions with great fit accuracy and minimal technological clearance, which makes prostheses not only convenient and functional, but also indistinguishable from your own teeth and aesthetically perfect.
Why is it worth installing zirconium on chewing teeth?
Zirconium crowns or cermets - what to prefer?
Patients often have the question of what is actually better: zirconium crowns or cermets? In order to answer it, it must be borne in mind that zirconium has many advantages over metal-ceramic designs. This material is much stronger, but it looks much more natural, so it is highly recommended to use it for the prosthetic procedure of the front incisors. Such material does not change color over time, and non-aesthetic metal strips do not appear at the dental base. In addition, zirconium is characterized by low thermal conductivity, in this regard, the material will not provoke an unpleasant sensation during the consumption of hot or cold food.
But, nevertheless, cermet has a huge plus, consisting in its cost. Turnkey zirconia products cost about four, or even five times more expensive than ceramic-metal constructions. This difference is due to the cost of consumables and the complexity of the technical process, but the aesthetic properties and durability of zirconium fully compensate for this. In any case, zirconium or cermet crowns - this is decided by each person individually, of course, not without the participation of an orthopedist.
How much zirconia costs for front teeth is of interest to many.
The issue of the cost of this prosthetics procedure
In order to say exactly how much a zirconium crown can cost, it is necessary to take into account a number of different factors that form its value. It is important to understand whether a tab is required for the crown, and how it will be installed on the implant or on your own tooth.
The cost of zirconium crowns in Moscow can vary greatly, which directly depends on the professionalism of the doctor and the level of dentistry in the selected clinic. On average, installing such products in Moscow today costs about twenty to thirty thousand rubles per tooth.
Having decided on their installation, it should be clarified what procedures are included in the price and how much more the patient will need to pay extra for the accompanying services. It will also be useful to clarify whether the selected dental clinic guarantees the installation of a zirconium crown. Next, we learn that in reviews people talk about such prostheses.
Reviews on crowns on teeth made of zirconium
Despite the high cost, more and more patients prefer the installation of crowns from zirconium. In the reviews, people write that this is by far the most successful solution.
You can also read in the comments that patients confirm the fact that zirconium dioxide is a very durable and wear-resistant material, and its shelf life is absolutely unlimited, and such prostheses can last a lifetime. In this statement, consumers have reportedly been convinced of their own experience.
Those who have been using them for a long time, in their reviews of zirconium teeth, report that the average life of such crowns, provided that they are properly maintained, ranges from fourteen to fifteen years, which is several times longer than the period of use of such metal-ceramic designs.
Thus, zirconium crowns that are perfect for teeth are considered one of the best solutions for restoring a beautiful smile. In such designs, aesthetics are combined at the same time with reliability and safety. In addition, prostheses have minimal contraindications for installation and will easily serve a person all his life.
