Tab input KK: indications, types, contraindications

The post-and-core Tab allows the dentist to restore full functionality of severely damaged tooth of a patient. Part of the product is placed in the root of the tooth, and the other part is on the surface and is a support for crowns, which will be established in the future.

General information

Tab post-and-core may be molded, in other words, one-piece or collapsible. Products are modeled individually for each patient, which is a good contrast to the pattern in the size and shape of the pins. Such a prosthesis is widely used to restore the integrity of teeth.

Tab post-and-core can be an independent type of prosthesis. But most often it is a reliable basis for high-quality fixing of the crowns. Service life of such products is not less than ten years, nozzles, made of precious metals, serve up to twenty years or more.

Readings

In the dental practice this element is installed in the following cases:

• Progressive destruction of the apex of the tooth (over 60%) when health condition of the root canal (otherwise the tab is post-and-core is not installed).
• The need to strengthen the dentin before applying the crown.
• Strengthening of dentin prior to installation of the bridges.

Contraindications

Tab on the tooth can't be installed in the patient in the presence of such contraindications:

• Low-quality perennial channels.
• Complete degradation of the channels.
• Cyst.
• A Granuloma.
• Inflammation that affects the tissues of the tooth.
• Unhealthy tooth mobility.
• The Manifestation of allergic reactions to the materials used.

How is the installation?

The Healing process is long, due to strictly individual approach. In the dental laboratory for each patient is made its own tab on the tooth. Minimum installation is one week. Be aware that quality work is carried out in specialized conditions (good dental, clinic with dental office). You cannot refer to doubtful professionals.

What to expect from your doctor during your first visit?

Primary visit to the dentist is accompanied by a complex of measures:

• Remove cavities with caries.
• If necessary, carried out the manipulations of root canal treatment, including pulp removal, treatment of oral antibacterial drugs (tab can be fixed on teeth with multiple roots or one, as long as they were healthy and strong).
• Holding the filling.
• Preparation of the root canal orthopedic. The doctor carries out a deep drilling reaching the roots. In the vacant cavity is subsequently inserted this type of pin.
• The Dentist takes an impression of the working tooth and the next, placed on the opposite jaw. This approach allows us to simulate perfect tab. Modern used computer modeling. In this case, the hardware scans the jaw, and the product is created using a special robot.
• Implementation of the provisional filling of teeth.

Second visit

Following the visit to the doctor means to perform such manipulations:

• The Removal of the temporary filling.
• Re-cleaning of the cavities and channels, drying.
• Post-and-core tab for tooth is fixed with special solutions.

Modeling the coronal portion can be implemented in two ways. First - by means of a surface-coated tab composite that can be performed during re-admission. If you need to conduct a more durable and high-quality restoration, from the top of the pin, the cast is removed, which is sent to the dental technician (it uses the services of any dentist). Prosthetics is carried out later.

A Third visit is carried out if necessary. Post-and-core tab for tooth covered with a crown.

Products

The Main function of these elements is to strengthen the tooth. For the manufacture of the tabs are engaged the most reliable and durable materials, which define the functionality:

• Made of precious metals. Usually gold is used, which is characterized by strength and durability. The disadvantage of this type one – prohibitive costs.
• The Oxide of zirconium, titanium tabs. Such materials are characterized by high strength and is completely biocompatible with the human body. Patients practically does not develop allergic reactions. Zirconium products are characterized by high aesthetics. The disadvantage is that when you remove the tabs (for whatever reason) it must be drilled out along with the tooth.

  

• Cobalt-chromium. Tab can cause allergies, but it is a very good option, based on the ratio quality/price.
• Ceramic. The element has a high aesthetic parameters, but the strength is poor. Usually these tabs are used to restore front teeth.
• Metal. The product has a metal core andthe ceramic shell. Such a post-and-core tab for a crown cheaper than ceramic, and at the same time much stronger.

Product Benefits

Setting tab has the following positive characteristics:

• The Doctor is able to restore even those teeth which are very badly damaged at the top.
• Tab is fixed with a permanent filling material, which prevents the development of carious lesions on the border of the dentin and the actual item.
• Best strength.
• The bit can be replaced without extracting the product (aesthetic dentistry).
• Prosthetics when you need support for bridges and crowns.
• The Dentist has the discretion to change the direction supragingival surface relative to the pin when correcting anomalies position of individual teeth.
• Aesthetics.
• Used for restoration of lateral and anterior teeth.
• Stump inlay will be under the crown securely locked.
• High Quality product has the anatomical form and tight to any cavities. This ensures a uniform load distribution.
• Large range of materials.
• Reliable fixation of crowns.
• Long service.

Collapsible or solid?

Cast stump inlay will often be used to restore those teeth that have only one root. Portable products recommended to install on mnogogrannyj teeth. Disposable models consist of core and pin, and a stump serves as a simulation of the coronal portion of the tooth, which then installs the crown. This design can be molded in parts and as a whole. If the patient is required to install bridges or partial dentures, cast tab allows you to avoid grinding the adjacent teeth. Such systems are more expensive than portable counterparts.

Manufacturer kultovyh tabs

Most attachments are manufactured in accordance with the following algorithm:

• Pre-prepared tooth, the cast is removed. Be aware that the preparation for an inlay is implemented with the help of a drill. The result is a ready-made cavity under the nozzle, which has an individual configuration.
• The cast, working in the laboratory, the technician makes the tooth model (usually of plaster).
• Conducted the scan area of the prepared model with the teeth.
• Implemented a computer simulation of the tab.
• Computer transmits the three-dimensional product model on the milling machine where it is cut.
• Nozzle are fired in special furnaces.
• The Product fixed on the tooth of the patient.

Multi-tabs

The Manufacture of these elements in the dental laboratory is no different from the production of simple single-rooted tabs, but on the condition that the channels of the tooth are parallel.

If this requirement is not fulfilled, in case of detection of dual teeth you can use tabs, in which there is one complete and a second additional pin. It will be included in the modified or artificially generated second channel.

If the tooth is three-channel, there is a need for the installation of portable structures. The most simple but reliable way of fabrication of these elements is modeling a monolithic shaft with channels for arranging additional. Such manipulation will allow to solve the problem in most cases. When you install the doctor should choose the main root for the implementation of the core pin. Work on the restoration of a tooth begins with him.

What is the difference between the tabs from the pins?

The Pin is a template design, which is a screw. It is installed in the root of the tooth. Metal under pressure can damage the weakened walls of the tooth roots, which causes loosening and falling out. Post-and-core nozzle evenly distributes the load, which eliminates the negative effects.

Requirements root

As noted above, post-and-core pin tab can be set only if a 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 greater length than the height of the tabs. The walls of the area should be of adequate thickness not less than 1 mm. This will allow the system to withstand chewing pressure. Well, if the gum was at least some part of the dentin.

The Dentist grinds off all the remaining walls of the tooth to 1-2 mm. the Tab should now cover the remaining tooth stump. In some cases, requires cutting the gums. This helps to expose the subgingival portion of the root. After these manipulations and the installation of temporary fillings, the patient must wait approximately 14 days to the coagulated phase epithelization.

Rehabilitation and recovery

Before the prosthetic tooth is exposed to preparation, so after installing the tabs can develop complications such as pulpitis or secondary caries. In a number of clinical pictures is evident soreness. To avoid such effects, it is necessary to exactly follow the doctor's recommendations.

Care tabs

After installation is complete, it is necessary to observe simple rules of hygiene:

• Twice-Daily brushing.
• Forcleansing the tooth with an installed construction and adjacent gums better to use brushes with soft bristles. Furthermore, it is shown to use special dental brushes, floss, which will help to keep clean the spaces between teeth.
• After eating, the oral cavity need rinsing with warm water or a dental solution that freshens breath and has anti-inflammatory action.
• Twice a year shows the examination by a specialist (prevention).

Costs of prosthesis

This method is quite expensive. The dependence of the price from the materials listed below:

• Post-and-core tab (price indicates lower limit) single-rooted metal – 2000 rubles.
• Tab duckorama metal-from 3000 rubles.
• Ceramic nozzle – from 12,000 rubles.
• Tab of Zirconia-from 15000 rubles.

Conclusion

Only an experienced, qualified specialist, working in appropriate conditions (licensed dental, clinic with dental office), able to carry out all manipulations at the proper level. For dental health do not save, and an appeal to the practicing dentist will eliminate the need for repeated prosthesis.
