What is a dental pin and why is it used in dentistry?

A tooth, susceptible to a disease and not receiving treatment, begins to deteriorate. If the damage is extensive, installing the seal will not help, but you can restore the tooth with a pin.

Some patients scare this technology, mainly because of not very aesthetic photos of the installation process itself. In fact, there is nothing terrible in this procedure, if you understand more.

Design and function

The pin is a rod made of strong material that is installed directly into the root canaltooth. It is a support that helps to maintain your own tooth root and do without its removal.

Both removable and non-removable dentures can be installed on the pin, as well as restorative materials. There are factory designs and made on an individual impression for an individual patient.

The installation of the rod is necessary not only to preserve the natural tooth root, but also to ensure that the dentition is not deformed, and the jaw does not lose its original contour.

Indications and contraindications to the

installation In dentistry, the pin setting in the tooth is prescribed at the following indications:

• tooth weakened by a neglected carious disease or pulpitis;
• tooth crown destroyed more than half;
• need to create a support for the subsequent installation of the prosthesis;
• process of implantation, implying the subsequent return of the tooth to the alveolus after removal of the infectious focus.

It is also necessary to comply with two conditions that allow the installation of the rod.

• the root wall should be thicker than 2 mm;
• root canal can be sealed to 2/3 and give it the shape of a cylinder.

As a contraindication, a number of factors distinguish:

• the presence of periodontal inflammation or its damage;
• tooth crown in the frontal part completely absent;
• roots are short and thin, which makes the rod installation impossible;
• presence of granuloma and cyst;
• blood diseases, especially those that affect its coagulation;
• diseases of the nervous system and mental disorders;
• pregnancy.

Most contraindications are somehow associated with other diseases of the oral cavity, so it makes sense to first eliminate all current problems, and then think about restoring the tooth. In the case of pregnancy, surgery can be postponed, well, in other situations it will be necessary to look for a different method of restoration.

Types of pins

Support rods differ in the manner of their fixation, the composition of the product and the form. Depending on the material, the following types of pins for teeth are distinguished:

1. Anchor is made from an alloy of gold and platinum or palladium. Variants of a lower price category suggest the use of stainless steel, brass, titanium. Such a pin can have two fixing methods. On the body of the active rod is made a special thread, thanks to which the pin is screwed into the channel. The method has drawbacks - it can lead to the destruction of the tooth during the installation, so it is used only in those cases where a full restoration of the crown is required. Installation passive type occurs with the help of medical cement. This method is used if the tooth has not yet collapsed to the end.
2. Fiberglass rods are a relatively recent discovery that allows you to make pins that are hypoallergenic. This is an appropriate option for patients who are allergic to any metal. Also, these products are made more lighter and more elastic, give less stress on the root and can be installed in one visit. If necessary, the rod can be removed without problems.
3. Carbon are made of carbon fiber and are the most aesthetic and durable. With such a design, the risk of a root fracture is practically absent.
4. Parapulpic view is a metal structure coated with a polymer mass and is used for additional support.
5. The cultured tab is a microprosthesis that can help even when the tooth is completely destroyed. On top of such a design is covered with a crown. It is made by individual casts, taking into account the relief of a particular tooth root, so for some time you will have to wait until the tab is ready.

• standard and the most common variant is the conical and cylindrical ;

• the level of location of the affected site relative to the position of the gum;
• the role of the tooth and the load on it - whether it is standing alone or enters a supporting structure for installing a bridge prosthesis.

It is also important to take into account the patient's health and the presence of allergies to him or her on metals or other materials.
