How is a pin placed in a tooth?

Inserting a pin into a tooth is a common dental practice. As a rule, this method is used in cases where the outer part of the tooth crown is severely damaged. In order not to remove a tooth and not to put a prosthesis, a special rod made of metal or other materials is often used, which is fixed in the root of the tooth and holds the outer part. Sometimes the pin serves as a support for a removable or bridge prosthesis, while maintaining the roots of the tooth.

Advantages and disadvantages of pin installation

Arguments for":

• The main advantage of using pins is the ability to restore the hard tissue of the tooth completely, even with severe destruction. In this case, the tooth does not have to be replaced with crowns, prostheses or implants. The pin helps to restore the tooth completely, as well as restore the ability to chew. In addition, from an aesthetic point of view, the tooth is also restored and looks healthy.
• The use of a pin design allows you to save the root system of the tooth, preventing a foreign body from touching the mucous membrane. This is especially important for people who have intolerance to certain materials.
• Another advantage of this technique is its long service life. As a rule, post manufacturers and dentists give a guarantee for 10 years. However, as practice shows, in fact, the pins can remain intact much longer. In the absence of a heavy load and compliance with hygiene standards, the rods can last up to 20 years without replacement.
• Today, a large number of different pins are used in medicine, which may differ in material, color and size. This makes it possible to choose a design depending on the individual characteristics of the patient, so that it best suits the size of the tooth and other conditions.
• Even in cases where the pin is selected for a prosthesis made of ceramic - a material that looks translucent in appearance, you can choose the best option. Metal rods in this case, as a rule, are not used, since they are visible, which spoils the aesthetic effect. For ceramics, it is best to use fiberglass rods, they are less visible and allow you to maintain a beautiful smile.

Flaws:

There are also disadvantages to the pin placement procedure.

• If the work is done poorly, then caries can form around the rod in the tooth. With this design, it is extremely difficult to detect the onset of the development of the disease, since the patient does not experience pain due to the absence of nerve endings, and from the outside the tooth is closed by the rod itself. Therefore, for a long time it is impossible to understand that caries has appeared in the tooth.
• With a strong impact on the teeth, a displacement of the rod may occur. This, in turn, threatens to damage the prosthesis or expand the hole in which the rod is fixed. In this case, patients experience severe pain. In most of these cases, if any complications occur, the patient is prescribed an operation to remove the pin design along with the root part.
• In addition, it should be understood that over time, the rod will wear out the tooth, and in any case it will have to be removed. In such situations, extraction is only possible completely, along with the root of the tooth. As a result, the patient will still need an implant.
• There is another drawback of the pin installation procedure - its cost. Of course, the installation of implants or prostheses may require more funds, however, the pin design is also not cheap, and not everyone can afford it.

How is the procedure?

Installation of a pin in a tooth can be used for all teeth, including canines or incisors. In addition, this design is applicable to any degree of tooth decay, even when the entire crown has collapsed. The procedure for installing the pin is carried out in several stages:

1. Tooth and root canal preparation.
2. The introduction of the rod into the root canal so that it goes into the bone. This is necessary in order for the tooth to be as stable as possible.
3. Pin fixation using a seal.
4. Covering the pin with an artificial crown or a special tab.

The rod is immersed into the root canal by two-thirds. That is, the main part of the structure is located deep in the root canal, which ensures its fixation inside. The part that is outside is well fixed with a filling substance. As a result, the patient receives a restored tooth that normally performs the function of chewing.

Does it hurt to put a pin in a tooth?

Most patients who are going to have a post implantation procedure are worried about the pain of this method, because the post is screwed very deep into the root canal. At the same time, everyone is well aware of how unpleasant the procedures for treating teeth, drilling and installing a seal. However, in this case, do not worry. During the installation of the pin, the patient does not feel pain at all. And it's not even about anesthesia. Before starting the screwing of the pin directly, the patient is removed the pulp, that is, the nerve, after which all the channels are well clogged. As a result, nerve impulses simply do not enter the brain.

Of course, the patient has the right to ask to be given anesthesia, but in most cases, dentists recommend not to do this, because when the anesthetic effect wears off, there is a high probability of discomfort. According to the reviews of patients who have undergone this procedure, the rod is screwed into the tooth very quickly, literally in 1-2 seconds, while the patient does not have time to get any pain or discomfort at this time.

Which pin to choose?

Today, dentists offer a considerable number of different pins. First, they differ in the materials from which they are made. Metal pins are made of titanium, brass, steel, palladium and even gold alloys. Non-metallic pins made of fiberglass, carbon fiber or ceramics are also made.

In addition, pin installations may differ in shape, mounting method and composition:

1. Standard pins in the form of a cone or cylinder. Used for minor damage to the tooth.
2. Metal pins are used in cases where the tooth is severely damaged, titanium structures are most often used.
3. Fiberglass pins. Such designs are elastic, do not interact with prostheses or saliva.
4. Carbon fiber rods. The most modern model of pins. They have a number of advantages in the form of a uniform distribution of the load on the root canal, high strength and maximum therapeutic effect.
5. Anchor rods. Such structures are made of titanium, today they are considered the best option for tooth restoration.
6. Individual rods. Such pins are made based on the individual characteristics of the root canal, they are more reliable, as they are well fixed.

The use of dental pins is very common today. At the same time, the therapeutic effect of the procedure remains for many years. Installation of a pin - the ability to restore a tooth without root removal and the use of prostheses or implants.
