Dental crown for implant: subtlety of installation

Today, no one is surprised at such a phenomenon as dental implantation. The method of restoring lost functions is by right in great demand among patients. However, before the operation it is necessary to consult a specialist. After all, you need to discuss all the points, starting with how the preparation will be carried out, and ending with the discussion of what kind of 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 crowns for implants

The first design that is made for the implant is a temporary crown. It is designed to fill the void of the dentition for the period during which a permanent prosthesis is made.

After the artificial root has taken root, the specialist sets a permanent crown. In modern clinics they usually use ceramics. Such prostheses are made in several variants. It can be metal-ceramic and metal-free crowns.

Often used for manufacturing and zirconium alloy. All these designs have their own peculiarities, pluses, minuses and cost. In order to know which one to install the crown on the implant, we will consider them by types.

Temporary construction

What is the function of this prosthesis, in addition to aesthetics? As we have already said, temporary crowns are placed on the implants for that period, while a permanent construction is being made. Of course, the aesthetic moment is very important. In addition, during this time, the gingival margin is formed after the operation. When the void in the jawbone is filled, there is no displacement of adjacent units and malocclusion. Another plus is a uniform load on the entire chewing apparatus. The cost of temporary crowns is low. Therefore, they are always used at a certain stage of implantation.

Cermet on the implant

The most common and demanded prosthesis. It is characterized by good appearance and strength. Also, cermets have proven themselves in accordance with the price and quality. This type of construction is practically no different from the prosthesis, which is covered with a sharpened tooth. The difference is only in the way of fixation. Such crowns are placed only on abutments made of metal. What it is?

The abutment is a device that is screwed into the implant. It replaces the lost supragingival part of the tooth. And after its installation, the orthopedist makes an impression for the subsequent manufacture of the crown. In conclusion, the specialist invites the patient to try on and fix the prosthesis.

Crown ceramic on implant

New methods of manufacturing prostheses are replacing the old technologies. Porcelain crowns are obtained from pressed ceramics . We are used to the fact that this material is fragile. To some extent, this is so. Therefore, it is used only for prosthetics of the frontal part of the teeth.

Also for the production of crowns, an alloy of zirconia and aluminum is used. The constructions differ in strength and incredible similarity to real teeth. But they also have a price. But in this case, the costs will be fully justified. With proper care of such crowns, they can serve a patient up to 20 years.

Features of the crown installation on the implant

The whole construction will consist of several parts.

1. Implant.

2. Abutment.

3. Crown.

In the course of the classical procedure, after the implantation of the artificial root, the specialist screws the abutment into it. This part replaces the sharpened stump of the tooth. This adapter is made of either metal or ceramic. Above the abutment is put on the crown.

There are also basal implants. They are used for a one-stage procedure to restore a lost unit of dentition. Such an implant already has a supragingival part. So after implantation, there is no need to screw the abutment into it. You can cover with crown immediately after 1-3 days. Sometimes a specialist needs a little more time (up to 7 days).

Installation process

You can put crowns on implants in two ways. There are two methods of fixation.

The first method is called "cement". Crown put on special glue.

The second version of the fixation is called "screw". Let's consider in detail these two methods of setting the crown.

Using a screw fixation, the specialist connects the prosthesis with the abutment outside the mouth. Then this composite structure is inserted into the artificial root. Then, with the help of 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 the screw is screwed through it, it will be closed with a special composite mixture. The specialist selects it according to color, so after carrying out all manipulations with the naked eye it is impossible to determine the place in which the hole was made.

When cementing the fixation, the specialist screws the abutment into the artificial root with the help of a screw. After this, using a composite glue, install the crown on the adapter. The composition has some damping properties. This distinguishes it from ordinary cement and allows to ensure reliable adhesion of surfaces. This is how the crown is placed on the implant.

Which fixing method is better and why?

In all European countries, a screw method is used to fix the crown to the implant. Experts consider him to be the most reliable, safe and convenient. If after installation of the crown on the implant with him, there are any problems, then they can be easily solved. The filling material, which is located above the screw, can be drilled. Thus, remove the crowns. Especially this moment is important when the patient has an extended structure (bridge) fixed on several implants. The use of a screw locking method will preserve the integrity of the entire bridge in the event that one unit is required for adjustments.

What is the purpose of cement fixation?

Earlier, when specialists were not equipped with high-precision equipment, this method of fixation was necessary. The extended design, executed with errors, could simply not become in the right places. For example, if the bridge is fixed on 3-4 implants by a screw method, it should be performed as accurately as possible.

Previously, the cement method of fixing smoothed out all the errors of the orthopedist and dental technician. Today, having the necessary equipment, only an expert with inadequate qualifications puts the designs on cement. This method does not allow you to further remove the crowns of one piece, if you need to make adjustments. So the patient should discuss with the doctor in advance all the nuances of the operation, up to the way in which he plans to fix the design.

Timing

With a one-stage operation, the crown on the implant is inserted after 2-5 days. But carrying out such a procedure requires certain conditions. Bone tissue should be sufficiently dense. This will allow the specialist to reliably fix the artificial root. And the fact that in the first days it is given a load when chewing food, allows him to integrate even faster. In this technique, special basal implants are used, as well as conventional implants designed for a two-stage operation.

Installation of the crown on the implant during the procedure in the classical way is expected in 2-4 weeks after the implantation of the artificial root. On order from the supplier and waiting for the delivery of the necessary abutments takes up to 14 days. The rest of the time is spent on making the crown.

The price of crowns from various materials

Of course, the full cost will depend on many factors. For example, the role that the clinic will choose the patient plays, and the way in which the procedure will be performed. The material from which the crowns are made and the selected type of abutment will also affect the price. We will quote the average figure for your reference.

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 structures together with the abutment will cost the patient about 45 thousand rubles.

What determines the life of implants

Factors that affect the life of the structure can be objective (independent of the patient) and subjective (the person's influence turns out).

The first group includes the strength of materials and the qualifications of the doctor, compliance with technology during the operation.

Subjective factors that reduce the service life of implants include bad habits, weak immunity, chronic diseases, insufficient oral care.

Usually, when the crown is placed on the implant, the expert consults the patient in detail. At first, a person is recommended soft warm food. The doctor may prescribe an antiseptic solution for the bath. Teeth cleaning should be done in a timely and correct manner. Some people mistakenly believe that artificial materials do not need care. However, it is not. The patient should carefully monitor the oral hygiene. Be sure to recommend that doctors brush their teeth twice a day, paying special 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 placed on the implant, you must visit the doctor twice a year. Do this with a prophylactic goal, even if the patient does not bother. It is worth noting that proper care will prolong the life of artificial teeth. And even if there are any defects on the crown (chips, cracks), all this can be easily corrected in the dentist's office.
