Today, no one is surprised by the phenomenon ofdental implantation. The method of restoring lost functions is rightly in great demand among patients. However, before the operation, you should consult with a specialist. After all, you need to discuss all the moments, starting with how the training will be held, and ending with the discussion of which crown will be installed on the implant. All this information will allow the patient to feel more comfortable during the procedure and plan their costs in advance.
Types of implant crowns
The first design, which is made forThe implant is a temporary crown. It is designed to fill the void of the dentition for the period during which the permanent prosthesis is made.
After artificial root is enoughcaught, the specialist establishes a permanent crown. In modern clinics, pottery is commonly used. Such prostheses are made in several versions. It can be metal-ceramic and metal-free crowns.
Often used for the manufacture and zirconiumalloy. All these designs have their own characteristics, pros, cons and cost. In order to know what kind of crown to install on the implant, we consider them by type.
Temporary construction
What is the function of the considered prosthesis, exceptaesthetics? As we have said, temporary crowns on implants are put on for the period while they are making a permanent structure. Of course, the aesthetic moment is very important. In addition, during this time the formation of the edge of the gums after the operation. When the void in the maxillary arch is filled, no displacement of adjacent units and disturbance of the bite is observed. Another advantage is the uniform load on the entire chewing apparatus. The cost of temporary crowns is small. Therefore, they are always used at a certain stage of implantation.
Metal-ceramic crown on the implant
The most common and popular prosthesis.It is characterized by good appearance and durability. Also, metal ceramics perfectly proved itself in accordance with price and quality. This type of construction is practically no different from the prosthesis that covers the ground tooth. The difference lies only in the method of fixation. Such crowns are put only on metal abutments. What it is?
Abutment is a device that is screwed intoimplant It replaces the lost supragingival part of the tooth. And after it is installed, the orthopedist makes a cast for the subsequent manufacture of the crown. In conclusion, the specialist invites the patient to try on and fix the prosthesis.
Ceramic crown on the implant
In place of the old technologies come new methods.manufacturing prostheses. Porcelain crowns are made from pressed ceramics. We are accustomed to the fact that this material is characterized by fragility. To some extent this is the case. Therefore, it is used only for prosthetic frontal teeth.
Also for the manufacture of crowns used alloyzirconium dioxide and aluminum. The designs are characterized by durability and incredible similarity with real teeth. But the price is appropriate. But in this case, the costs will be fully justified. With proper care for such crowns, they can serve the patient up to 20 years.
Features of the installation of the crown on the implant
The whole structure will consist of several parts.
1. Implant.
2. Abutment.
3. Crown.
During the classic procedure after implantationArtificial root specialist screw abutment in it. This part replaces us with a polished tooth stump. This adapter is made of either metal or ceramic. A crown is put on top of the abutment.
There are also basal implants.They are used for a one-step procedure for restoring a lost unit of the dentition. Such an implant already has the supragingival part. So after implantation, there is no need to screw the abutment into it. You can immediately cover the crown in 1-3 days. Sometimes a specialist needs a little more time (up to 7 days).
Installation process
Put the crowns on the implants in two ways. There are two methods of fixation.
The first method is called "cement." The crown is put on a special glue.
The second fixation option is called "screw." Consider in detail these two methods of installing the crown.
Using screw fixing, the specialist connectsprosthesis with abutment outside the mouth. Then this team is inserted into an artificial root. Next, using a screw, the doctor performs fixation with the implant. With this method a small hole will be made on the crown (on the chewing part). After screwing a screw through it, it will be closed with a special composite mixture. The specialist selects it by color, so that after carrying out all the manipulations with the naked eye it is impossible to determine the place where the hole was made.
When cement fixation specialistScrew assistance screwed the abutment into the artificial root. After that, using composite glue, install the crown on the adapter. The composition has some depreciation properties. This distinguishes it from conventional cement and allows for reliable adhesion of surfaces. This is how the crown is placed on the implant.
Which fixing method is better and why?
Во всех европейских странах применяется винтовой method of fixing the crown on the implant. Experts consider it the most reliable, safe and convenient. If after installing the crown on the implant any problems occur with it, then they can be easily solved. Sealing material that is above the screw can be drilled. Thus remove the crown. This moment is especially important when the patient has an extended structure (bridge) fixed on several implants. The use of a screw fixation method will allow preserving the integrity of the entire bridge in the case when adjustments are required by one unit.
Why was cement fixation invented?
Earlier, when specialists in service are notIt was a high-precision technology, this method of fixation was necessary. The lengthy design, made with errors, could simply not be in the right places. For example, if the bridge is fixed on 3-4 implants in a screw way, it should be performed as accurately as possible.
Previously, the cement method of fixing smoothed allerrors of work of the orthopedist and dental technician. Today, with the necessary equipment, only a specialist with insufficient qualifications puts structures on cement. This method does not allow you to further remove the crowns one by one, if there is a need to make adjustments. So the patient must discuss with the doctor all the nuances of the operation in advance, up to the way in which he plans to fix the structure.
Timing
With simultaneous operation of the crown on the implantput in 2-5 days. But carrying out such a procedure requires compliance with certain conditions. Bone tissue must be dense enough. This will allow the specialist to securely fix the artificial root. And the fact that already in the first days the load is given to it when chewing food allows it to integrate even faster. In this technique, special basal implants are used, as well as conventional ones intended for a two-stage operation.
Place the crown on the implant duringprocedures in the classical way are expected in 2-4 weeks after implantation of the artificial root. It takes up to 14 days to order from the supplier and wait for the delivery of the required abutments. The rest of the time spent on making the crown.
The price of crowns made of various materials
Of course, the full cost will depend onmany factors. For example, it plays a big role, which clinic will choose the patient, and how the procedure will be carried out. The material from which the crowns are made, and the chosen type of abutment will also affect the price. We give the average figure for review.
Metal ceramics on a metal abutment will cost the patient about 15 thousand rubles.
Dental crowns on porcelain implants cost about 25 thousand rubles.
Zirconium constructions together with an abutment will cost the patient approximately 45 thousand rubles.
What determines the lifetime of the implants
Factors that affect the life of the structure can be objective (not dependent on the patient) and subjective (influenced by a person).
The first group includes the strength of materials and the qualifications of a doctor, compliance with technology during the operation.
The subjective factors that reduce the service life of implants include bad habits, weak immunity, chronic diseases, and insufficient oral care.
Usually, when a crown is placed on the implant,The specialist advises the patient in detail. At first, soft warm food was recommended to the person. The doctor may prescribe any antiseptic solution for baths. Brushing your teeth should be done promptly and correctly. Some people mistakenly believe that artificial materials do not need care. However, it is not. The patient should carefully monitor oral hygiene. Doctors recommend that you brush your teeth twice a day, paying particular attention to the border between the gums and the crown.
The use of dental floss increases the efficiency of the hygienic procedure.
If a crown is installed on the implant, it is necessaryvisit a doctor twice a year. This is done for preventive purposes, even if the patient is not disturbed by anything. It is worth noting that proper care will prolong the service life of artificial teeth. And even if there are any defects (chips, cracks) on the crown, all this can be easily corrected in the dentist’s office.
