What is a pin in the tooth and what is this dental element for?

Modern dentistry can restore the dentition in the smile zone in a dozen ways.Each of them allows to solve a specific clinical problem.For example, if there are chips on the teeth, then the defect is easiest to fix with the help of veneers.With carious tooth decay, you can and should use tabs.But if the tooth has no support or it is too weak, then dentists use dental pins to solve the problem.

What is a pin in the tooth?

What is this can be understood from the following description: pin-dental element in the form of a needle , used for fixing a completely or partially destroyed tooth in the channels.Using this element allows you to restore the tooth in the event that its outer part is preserved at least 20%.

The tooth pin is used in the following cases:

• The destruction of the outer tooth crown.
• When it is required to stop further tooth decay after caries treatment.
• In case you need to create a support for installing a bridge prosthesis.

A pin in the tooth is often used as a basis for tooth restoration using composite materials.Its use makes it possible to accelerate and facilitate restoration work.Moreover, the use of a pin removes restrictions on the load on the restored tooth.

Advantages and disadvantages of using

The main advantage of this technology is the ability to restore even severely damaged teeth.The base of the tooth will remain untouched.Its does not have to be replaced with an implant.In fact, the tooth pin allows you to avoid the removal of a completely or partially destroyed tooth.

The use of pins does not interfere with the root system of the front teeth.As a result, dentists ensure that foreign objects will not irritate the mucosa, as is the case with removable dentures.This is very important for people with hypersensitivity and allergy to certain dental materials.

Another undoubted advantage of using dental pins is a significant service life.The vast majority of dental pins have a guarantee of 10 years, but in practice their life is often 20 years.True, this is only if the spoke was not overloaded.

Due to the fact that the tooth pin can be made of different materials , you can choose the solution for any situation.For example, you need to install a ceramic denture.Naturally, the metal here will be superfluous, since it will shine through the material of the crown.The problem is solved using a dental pin made of fiberglass.This is a light material that does not affect the appearance of the prosthesis.

• has the following disadvantages:
  • There is always a risk of caries around the pin.In this case, the disease will be found only at the last stage.
  • The excessive strength of the pin can cause its displacement during operation, which will damage the prosthesis and the roots of the tooth.To solve the problem, you have to remove it with the tooth.
  • By the end of the life of the needle, the prosthesis will necessarily protrude.This will lead to the need for a complete tooth extraction, because otherwise it can not be restored.

  There is another little mention of a dent in the tooth by a dentist - the price.Of course, the spoke stands cheaper than the crown or implant , but often you need to install several pins at once and it can hurt to hit the wallet.What materials are used to make dental pins?

  According to the type of materials used, the spokes are divided into two groups.

  Metal

  Alloy spokes are the most common.For their manufacture are used: titanium, stainless steel, gold, palladium and various alloys.Selection of a metal for the manufacture of the spoke is done taking into account the characteristics of the patient's body.In particular, the reaction of the patient's body to a particular material is determined.

  All metals used to make rods are hypoallergenic.That is, rejection reaction is extremely rare.The most popular is gold.The fact is that for this metal practically there are no allergic reactions of .Therefore, if the dentist is unsure of the reaction of the patient's body to a particular material, then a choice is made in favor of gold.

  Naturally, gold is used only in the form of an alloy.In its pure form, it does not have the proper characteristics to perform the necessary functions.

  Titanium knitting needles are used in case of severe tooth decay.The fact is that in terms of its strength characteristics this material has the greatest strength.The problem of titanium rods is their minimal plasticity.That is, with significant loads, they easily damage the crowns and holes of .

  Other metals are only used when the patient has money for them.

  Non-metallic

  This group includes spokes made of fiberglass, carbon fiber and dental ceramics.

  Glass fiber knitting needles are very durable and light.At the same time they have sufficient flexibility and elasticity.This makes them almost the best choice, because under load they can bend, but then they will certainly return to their original position.

  Externally fiberglass pins are translucent , so they are great for tooth restoration in the smile zone.

  Carbon-plastic knitting needles are practically not used today.The fact is that their advantage in the form of good elasticity is leveled by insufficient strength.After the appearance of fiberglass, this material gradually disappears from dentistry.

  Ceramic knitting needles.They have neither the elasticity nor the strength.So for what do dentists like them?For aesthetic properties.Pins made of this material do not stand out against the background of other materials.This is clearly seen in the photo.

  Types of pins by fixation type

  By the type of fastening the spokes are divided into active and passive .

  Active pins are distinguished by the presence on their surface of special grooves, providing a reliable attachment inside the channel.This pin is simply screwed.

  This view is only used if you have not previously expanded the channel.

  The advantage of active spokes is the reliability of their fastening and durability.Disadvantage - the complexity of installation and excessive pressure on the tooth tissue in the installation site.

  Passive pins are suitable for tooth restoration after serious damage.This needle allows you to treat teeth after tooth decay.It is not a secret that after treatment of this disease there remains a large hole , in which the active pin is not fixed.And the passive spoke itself is useless in such a situation.Therefore, dentists fill the hole with cement, into which the spoke is put.The installation technique can be seen in the photo.

  The passive pin is installed very easily, but here for strength and reliability of fastening it is much inferior to the active colleague.

  Contraindications to the use of

  pins Before installing dental knives, dentists must perform a series of analyzes of for the following contraindications:

  • Any blood diseases that negatively affect coagulation.
  • Menstruation, because at this time a woman develops a hormone that reduces blood clotting.
  • Nervous diseases.
  • Periodontitis.
  • Caries.
  • Cysts and granulomas
  • Insufficient thickness of the root.

  Possible complications

  Unfortunately, even in the case of an ideal installation, the remains at risk for complications of .

  The most terrible problem is the rejection of a foreign object of organisms.The first signs of this complication are manifested just a few days after the operation.Coping with the problem can only be removed and replaced by a spoke.

  Most often after the installation of the pin develops such a complication as periodontitis.The cause of inflammation usually become errors dentists during work.

  The patient himself can provoke a complication if he does not follow the rules of hygiene.Brush your teeth need to start as early as the second day after the operation, rather than wait for complete healing.

  Virtually all patients after the installation of the pins are marked by swelling and pain.They pass within the first week after the operation.

  Price

  It will not be superfluous to know about how much a pin is in the tooth.The price for this item depends on the material and type.The most expensive are fiberglass - 1500 rubles per piece .The most affordable price for metal spokes is 600 rubles.In the event that the dental pin was manufactured on an individual order, its price may increase by 300 rubles.
