Kultevaya tab: indications for use, types, contraindications

The cult insert allows the dentist to restore the full functionality of the severely damaged tooth of the patient. Part of the product is placed in the root of the tooth, and the other part is located on the surface and is the support for the crown, which will be installed in the future.

General information

The core insert can be cast, in other words, integral or demountable. Products are modeled individually for each patient, which is a profitable difference from the template-sized and shaped pins. Such prosthetics are widely used to restore the integrity of the teeth.

The insert of the stump can be an independent type of prosthesis. But most often it is a reliable foundation, necessary for qualitative fixation of the crown. The service life of such products is at least ten years, nozzles made of precious metals, serve up to twenty years or more.

Indications

In dental practice, this element is established in the following cases:

• Progressive destruction of the apex of the tooth (more than 60%), provided that the tooth channel is healthy (otherwise the stump tab is not set).
• The need to strengthen the dentin before applying the crown.
• Strengthen dentin before installing bridges.

Contraindications

The insert on the tooth can not be installed to the patient if there are such contraindications:

• Poorly healed channels.
• Complete degradation of channels.
• Cyst.
• Granulomas.
• Inflammation that affects the tissues of the tooth.
• Unhealthy mobility of teeth.
• Manifestation of allergic reactions to the materials used.

How is the installation done?

The treatment process is long, which is due to a strictly individual approach. In the dental laboratory for each patient is made its own tab on the tooth. The minimum installation period is one week. It should be taken into account that quality work is carried out in specialized conditions (good dentistry, polyclinic with dental office). It is impossible to address to questionable specialists.

What can I expect from a doctor on my first visit?

The primary visit to the dentist is accompanied by a whole range of activities:

• Removal of cavities affected by caries.
• If necessary, manipulations for the treatment of the dental canal, including the removal of pulp, treatment of the cavity antibacterial drugs (the tab can be fixed on teeth with several roots or with one, the main thing is that they are healthy and strong).
• Carrying out sealing.
• Preparation of the dental canal with orthopedic care. The doctor conducts deep drilling, reaching the roots. In the released cavity, this type of pin will subsequently be inserted.
• The dentist removes the impression from the working tooth and the adjacent teeth placed on the opposite jaw. This approach allows you to model an ideally convenient tab. Computer centers are used in modern centers. In this case, the equipment itself scans the jaw, and the product is created using a special robot.
• Implementation of temporary tooth filling.

Second visit

The next visit to the doctor involves performing such manipulations:

• Seizure of the temporary seal.
• Re-sanitation of cavities and channels, drying.
• The culture insert for the tooth is fixed with special solutions.

Simulation of the crown part can be realized in two ways. The first is by lining the surface of the insert with a composite, which can be done during re-reception. If it is necessary to carry out a more durable and qualitative restoration, a mold is removed from the tip of the pin, which is sent to the dental technician (any dentistry uses it). Prosthetics are carried out later.

The third visit is carried out if necessary. The culture insert for the tooth is covered with a crown.

Types of products

The main function of these elements is to strengthen the tooth. For the manufacture of tabs, the most reliable and durable materials are attracted, which determine the type of product:

• Made of precious metals. Usually, gold is used, which is distinguished by its strength and durability. The disadvantage of this species is one - an excessively high cost.
• Oxide-zirconium, titanium tabs. Such materials are characterized by high strength and completely biocompatible with the human body. The patients practically do not develop allergic reactions. Zirconium products are highly esthetic. The disadvantage is that when removing a tab (for some reason), it must be drilled with the tooth tissue.

• A cobalt-chrome look. The tab can cause allergies, but this is a very good option, based on the price / quality ratio.
• Ceramics. The element has high aesthetic characteristics, but the strength leaves much to be desired. Usually, these tabs are used to restore the front teeth.
• Metal ceramics. The product has a metal core and a ceramic shell. Such a cult insert for a crown is cheaper than a ceramic one, and at the same time is much stronger.

Product Advantages

Setting tabs has the following positive characteristics:

• The doctor has the ability to restore even those teeth that are very badly damaged in the upper part.
• The insert is fixed with a permanent filling material, which prevents the development of carious lesions on the border of the dentin and the element itself.
• The best strength.
• The crown can be replaced without removing the product (aesthetic dentistry).
• Prosthetics are made when a support is needed for bridges and various kinds of crowns.
• The dentist, at his discretion, can change the direction of the supragingival surface relative to the pin itself when correcting the anomalies of the position of the individual teeth.
• Aesthetics.
• It is used for restoration of lateral and anterior teeth.
• The cultivated insert for the crown is securely fixed.
• The quality product has an anatomical shape and fits snugly against any cavities. This ensures an even load distribution.
• Large range of materials.
• Reliable fixation of the crown.
• Long service.

Demountable or solid?

A cultivated cast insert is often used to restore those teeth that have only one root. Collapsible products are recommended to be installed on multicore teeth. Non-dismountable models consist of a stump and a pin, and the stump serves as an imitation of the crown part of the tooth, where the crown is subsequently installed. This construction can be cast in parts and entirely. If the patient needs to install bridges or clasp dentures, the cast insert allows avoiding the grinding of adjacent teeth. Such systems are more expensive than demountable analogs.

Making of cultic tabs

Most attachments are made in accordance with the following algorithm:

• With a pre-prepared tooth, the impression is taken. It should be taken into account that the preparation for the insert is realized with the help of a drill. As a result, a ready-made cavity is formed under the nozzle, which differs in its individual configuration.
• According to the impression, acting in the laboratory, the technician makes a model of the teeth (usually of gypsum).
• The site of the prepared model is scanned with a tooth.
• The computer simulation of the tab is implemented.
• The computer transmits a three-dimensional model of the product to the milling machine, where it is sawed.
• The nozzle is fired in special ovens.
• The product is fixed on the patient's tooth.

Multi-root tabs

The production of such elements in the dental laboratory is no different from the production of a simple single-root tab, but on condition that the tooth canals are parallel.

If this requirement is not met, in the case of identifying two-channel teeth, you can use tabs in which there is one full and second additional pin. It will go into the modified or artificially formed second channel.

If the tooth is three-channel, it becomes necessary to install demountable structures. The simplest, but reliable way of manufacturing these elements is the simulation of a monolithic pin with channels for additional arrangement. Such manipulations will solve the problem in most cases. During installation, the physician must select the main root for insertion of the main post. Work on restoring the tooth begins precisely with it.

What is the difference between tabs and pins?

The pin is a template design, which is a screw. It is installed in the root of the tooth. Metal under the influence of pressure can damage the weakened walls of the roots of the teeth, which causes the loosening and loss. Kultevaya nozzle evenly distributes the load, which eliminates the negative consequences.

Requirements for the root

As noted above, the stump pivot tab can be installed only if the dentist is confident in the reliability of the root. In addition, it is necessary to exclude the development of inflammatory processes.

The root must have a longer length than the height of the tab itself. The walls of the section must be of sufficient thickness, not less than 1 mm. This will allow the system to resist chewing pressure. Well, if there is at least some part of the dentin over the gum.

The dentist stakes all the remaining tooth walls up to 1-2 mm. The tab should cover the remaining dental stump. In some cases, gum pruning is required. This helps to expose the subgingival part of the root. After such manipulations and setting a temporary seal, the patient should wait about 14 days for the coagulated site to epithelize.

Rehabilitation and recovery

Before the prosthesis, the tooth is dissected, so complications such as pulpitis or secondary caries can develop after insertion. In a number of clinical pictures, soreness appears. To avoid the occurrence of such consequences, it is necessary to follow the recommendations of the doctor exactly.

Care of tabs

After the installation is completed, you must follow the simple hygiene rules:

• Daily two-time cleaning.
• To clean the tooth with the installed structure and the adjacent gum, it is better to use brushes with soft bristles. In addition, it is shown to use special dental brushes, threads, which will help keep the gaps between the teeth clean.
• After eating, the oral cavity should be rinsed with warm water or a dental solution that refreshes the breath and has an anti-inflammatory effect.
• Twice a year, an examination is shown with a specialist (for the prevention).

Cost of prosthetics

This method is quite expensive. The dependence of the price on the materials of manufacture is indicated below:

• Kul'tovaya tab (price denotes a lower limit) single-root metal - 2000 rubles.
• Two-rooted metal insert - from 3000 rubles.
• Ceramic nozzle - from 12,000 rubles.
• The insert of zirconium dioxide - from 15,000 rubles.

Instead of concluding

Only an experienced, qualified specialist who works in appropriate conditions (licensed dentistry, a polyclinic with a dental office) is able to carry out all manipulations at the proper level. On the health of the teeth should not be saved, and the appeal to a practicing dentist will eliminate the need for repeated prosthetics.
