Hur man sätter tänderna på stift vilka typer av stift som används

Tooth enamel is not accidentally the most durable tissue of the human body, because it is on the enamel that daily significant mechanical loads occur.

Features of the chemical composition, as well as features of the histological structure allow the teeth to perform its function on a daily basis, undergoing significant mechanical effects.

However, the mechanical load( within reason, of course) is not the main threat to the integrity of the tooth.A much more serious threat is represented by sharp temperature changes, chemical factors, as well as omissions in matters of personal oral hygiene.

Due to the abundance of provoking factors and diseases leading to tooth decay, dental diseases are so common.In modern dentistry, it is customary to fight for the preservation of the organ to the last.

The most diverse methods of treatment are applied, but in some cases the pathological process goes too far, and then the only way out is prosthetics.Thanks to a number of advantages, the pivot method of prosthetics enjoys a stable popularity.

Tooth decay are factors contributing to the pathological process

Factors contributing to tooth decayenough.Conditionally they are divided into external and internal.

To external include:

1. Sharp temperature changes.With a rapid transition from low temperatures to high and vice versa, microcracks appear in the tooth enamel, in which suitable conditions are created for the vital activity of microorganisms, which significantly accelerate destructive processes.Excessive mechanical load.Hitting and excessive pressing also contributes to tooth decay - opening beer bottles with teeth is not the best idea.
2. Chemical exposure.One of the most aggressive factors affecting the dental tissues.A serious enough threat in the chemical terms is carried by many popular alkaline or acidic drinks, which threaten the health of the teeth even in the absence of sugar in them.
3. Inadequate oral hygiene.Insufficient or completely absent daily cleaning of teeth also greatly contributes to their destruction.

Internal factors include:

1. Genetic predisposition.Hereditary features of connective tissue, as well as genetically determined weakening in anti-caries protection, may lead to the fact that teeth will have to be treated despite proper nutrition and oral care.
2. Pathology of the metabolism, often associated with inappropriate nutrition.This can lead to the beginning of the processes of demineralization of dental tissues, and to reduce their stability.
3. Negative effects of certain procedures and medications.
4. Hormonal disorders, leading to disruption of mineralization of bone and dental tissue.This can be observed, for example, with various diseases of the thyroid gland.
5. Incorrect bite, which can lead to uneven distribution of load between different areas of the teeth, and provoke destruction of enamel areas experiencing more intense load.

Types of pins used for pin prosthetics

In modern dentistry, various materials are used for both filling and pins.They differ in strength, durability, the reaction of the body to the pin( there are immunologically inert materials, such as, for example, titanium, but some alloys can cause even allergic reactions) and cost.The following pivot options can be distinguished.

Anchor

This view is in turn divided into active pins and passive.The active version of the anchor pin is fixed in the root canal with the help of threaded threads( the active variant is tried less often, since when it is screwed in, there are often problems), the passive thread does not have and is fixed with special compounds.

Such constructions from alloys of various metals are made, actually the material in this case determines the cost - the pin can be made of alloys of platinum or palladium, or it can be made of titanium or stainless steel.

Fiberglass

This material is recognized as hypoallergenic, which is especially important if the patient's body reacts aggressively to metals.Also, this material is light and elastic, it can be easily removed if necessary.

Carbon fiber

The combination of mechanical parameters of pins from carbon fibers approaches the parameters of tooth tissues as much as possible.Also, when using this material, the probability of a root fracture is significantly reduced.

Culture tab

This design can be referred to as a microprosthesis, and is used when the crown is severely damaged.Each such tab is individual, as it is made from the impression of the affected tooth.The only drawback of this design - for such treatment is quite a lot of time.

Parapulp

These pins have a special design - the rod consists of a metal alloy covered with a polymer material on top.They are not installed in the cavity of the tooth, but serve to support the basic structure.

Installation of pins - indications and contraindications

Like any medical intervention, the installation of pins has its own indications and contraindications.

For indications in the case of this method of treatment include:

• Serious degree of destruction of the crown of the tooth, or its complete absence.
• Such designs can serve as a support for bridges.
• Mechanical strengthening of depulled teeth.
• For attachment of implantable teeth.Replantation is the installation of a previously removed tooth.

Contraindicated use of such structures in such cases:

• If there are untreated diseases of periapical tissues.
• In case of obstruction of the root canals.
• Too short roots, especially if their walls are considerably thinned, also make it impossible to install the pins.
• In case of atrophy more than three-fourths of the bone tissue of the alveolar process.
• A quarter root root, or the defect of any of its walls with dimensions of more than a quarter of the root's size, also makes it impossible to install the pin structures.

There are also a number of requirements for the condition of the root of the tooth, compliance with these requirements is necessary in order to install the pin without any complications, and the design has served as long as possible.

Roots must be:

• Sufficient length - more than the length of the crown to be installed.
• The penetration of the root canal should be sufficient for a length equal to the length of the pin to be installed.
• There should be no signs of acute or chronic periodontal inflammation.
• The root walls should be of sufficient thickness( more than 2 mm), in order for the structure to cope with the load transmitted through the pin during chewing.
• The root of the tooth must have sufficient stability.

Application of pins - advantages and disadvantages of the

method. Any treatment method has its advantages and disadvantages, based on which the specialist in each case chooses in favor of one or another technique.

The benefits of the installation of the pins include:

• The ability to restore hard tooth tissue even with a significant degree of its destruction.
• With this method of restoration, the root system of the tooth is preserved, which virtually eliminates the contact of the artificial material with the mucosa.
• When using fiberglass, it is possible to restore including front teeth.
• Significant durability of the tooth on the pin.
• Lower cost compared to a number of other methods, as well as the choice of material.

The disadvantages of the method are:

• Quite high probability of rapid tooth decay, as well as the development of a number of complications in the case of errors made during installation.
• In case you need to remove the pin, remember that most of the designs will likely be deleted along with the root, since they are fixed to it very firmly.
• If there are any errors in the installation process, caries may develop.
• There is a possibility of thinning of the remaining walls of the tooth, which after a certain time can lead to complete destruction of the tooth.

Possible problems with dental pins, features of care for such structures

Special care pin designs require unless in the first days after installation - do not recommend taking too solid food, eat nuts or seeds, and also use toothpicks.After a certain time, oral hygiene with such designs will not differ from that of a person with healthy teeth.

You should also remember that to prevent the development of diseases and complications it is necessary to regularly undergo a preventive examination.

Pain sensations are considered normal only the first days after installation.If the tooth with the pin began to hurt after a couple of months after the procedure, then this is a sufficient reason for contacting the dentist.

It should also be taken into account that it is possible to develop an allergic reaction to almost any of the materials used.This can manifest not only the local reaction of tissues, but also a general malaise, so in the first weeks it is desirable to monitor the body temperature.

Despite the relatively high strength, the pin can still break.In this case, you will have to apply for specialized care, since it is impossible to eliminate such a problem yourself, most likely, you will need a full prosthesis with the removal of the root.

The pivot method of prosthetics is a fairly common method of restoring even heavily damaged teeth.

The high reliability of the correctly installed structure, as well as the complete restoration of the tooth function, make it possible to use this method as a slightly more accessible method in comparison with a number of other methods of prosthetics.
