Restoration of a tooth without prosthetics - building on a pin

Restoration of teeth in modern dentistry involves many methods.

One of them is font extension.

During restoration, the severity of tooth damage does not play a decisive role.

Therefore, the build-up can be carried out even with the complete destruction of the crown.

The main condition is the presence of a healthy root.

Most recently, a completely destroyed tooth was removed. But today, dentists rarely turn to such manipulation.

Modern preparations and technologies make it possible to recreate a destroyed tooth. For example, by building on the font. How is aesthetic restoration performed?

Pin - a rod that is installed in the root canal and is a support for the future tooth. An artificial structure is built up on it. The determining factor is the material of the pin.

Indications

Dentists recommend restoring in the following cases:

• the presence of cracks and chips on the enamel of the tooth;
• creation of a supporting structure for the subsequent installation of orthopedic prostheses;
• malocclusion;
• severe caries;
• mechanical trauma to the tooth.

Contraindications

There are few contraindications, but you should also familiarize yourself with them:

• restoration with a completely destroyed root part;
• acute inflammation of the gums;
• thin root walls (less than 2 mm);
• the presence of a cyst or granuloma.

Running caries is also a contraindication. However, after treatment, restoration of the tooth is possible.

What are dental pins and their purpose is described in more detail in the video.

Species and types

Depending on the desired result, the degree of complexity of the deformation and violation of the tooth, several types of pins are distinguished. In addition, features in fixation and shape are noted.

Classification by material of manufacture

There are metal and non-metal pins. Their main function is strong fastening and reliability.

metal

Similar products are designed to reinforce the tooth. Metal alloy provides high strength and full biocompatibility.

Unique processing completely eliminates oxidation:

1. Titanium anchor pins. Titanium is neutral for humans and does not cause allergic reactions. Thanks to the protective film, oxidation is completely excluded. Anchor pins made of titanium are highly durable. This allows them to be used as the basis for a three-dimensional structure.
2. Brass- it is an alloy of zinc and copper. Possesses low strength and reliability. The main disadvantage is low anti-corrosion properties. Some pins are covered with gold plating, but this does not give the desired effect. Because the spray layers are damaged during the installation of the pin.
3. Precious metals(gold, silver, platinum, palladium, etc.) are widely used in dentistry. Provide rigidity and reliability of a design. They are well combined with the body and quickly take root in the tissues.
4. Palladium is a precious metal. Has good characteristics. Does not cause allergies.
5. Stainless steel has low corrosion resistance, low strength, and significant chemical activity, which can manifest itself in the form of allergic reactions.

non-metallic

They are used as a basis for all-metal crowns and for highly artistic restoration of teeth. They have high light transmission.

1. Ceramic. From an aesthetic point of view, they are an ideal material for extensions. They have high strength and sufficient rigidity. Made from white material. However, they have low elasticity and connecting ability.
2. Fiberglass. Lightweight, flexible and durable construction. After a long load, they regain their shape. The translucent, white shade of the rod is ideal for restorations. One of the most popular materials used in building.
3. carbon fiber. Stretchy, durable carbon fiber is durable. They take the main load, transferring its small part to the base. Today it is one of the modern and optimal types of pins.
4. Gutta-percharods have high tissue compatibility. Durable and elastic. A reliable form, even after the expiration of time, is not destroyed. Made from hypoallergenic, non-toxic material.

By forms

The shape of the pin also plays a role in the effectiveness of the procedure. It is selected according to the anatomical features of the structure of the tooth.

Consider the main forms of pins:

1. conical shaperepeats the anatomical structure of the tooth. Due to this, the risk of fracture of the dense walls of the root is significantly reduced. Provides strength and good retention of restorative materials.
2. Screw posts are used when most of the crown is preserved. For this form, good patency of the canals is important. The pin is not only screwed in, but also fixed with a special solution.
3. Cylindrical pin - the simplest. But its shape does not match the anatomical features. The risk of perforation is very high. Designed for teeth with short and massive roots.
4. Cylindrical pin intermediate type. It, in comparison with a cylindrical one, is more durable and stable (compared to a conical one).

Fixing Methods

The extension on the pins also differs in the type of fixation. The procedure is carried out in two ways:

• the active method is the most reliable. The shaft of the pin, with the help of a thread, is installed and fixed in the hard tissue of the tooth. Used for severe damage;
• passive method- the pin is installed and fixed with the help of additional materials. Used to strengthen teeth.

Advantages

Tooth extension on the pin has a number of advantages:

• no need for prosthetics;
• relatively low cost of the procedure;
• restoring the beauty of teeth in case of malocclusion;
• the possibility of recreating the functionality and shape of the damaged tooth.

Flaws

Any method has its drawbacks, and building on a pin is no exception:

• incorrect installation of the pin affects the development of caries;
• some metal products are subject to corrosion;
• in some cases, the removal of the pin is not possible and the entire tooth is removed;
• over time, the walls of the tooth become thinner, which entails the need for repeated restoration.

Installation

The extension process is carried out in several stages:

1. Initial preparation of channels. They are processed and cleaned.
2. The root is being prepared. With the help of special tools, the desired size of the hole for the pin is recreated.
3. The pin is inserted carefully. The rod must fit tightly into the dentary, which makes the design reliable.
4. The product is fixed with filling materials. Particular attention is paid to the root tip.
5. Crown formation. After fixing the rod, the process of creating the shape and size of the damaged tooth begins.
6. Final finishing. To achieve a natural effect, an artificial tooth is ground.

Correct installation of the pin allows you to restore all previously lost tooth functions.

Complications

Even with the most insignificant procedure, complications can occur that are independent of the professionalism of the dentist:

• inflammatory process on the gums;
• possible swelling of the gums;
• the presence of pain;
• with improper hygiene, inflammation of the tissues of the oral cavity is possible.

Care after restoration

Several rules must be followed:

• after the procedure, the doctor will prescribe a rinse with antiseptic agents;
• the first days when brushing your teeth, you need to exclude the area with the extended structure;
• before going to bed, clean your teeth with a floss;
• Every 6 months you need to see a doctor.

Complete hardening of the extended tooth occurs within a few days. During this period, it is not recommended to drink coffee or strong black tea, drinks and products, which include both synthetic and natural dyes.

Price

Each patient is interested in the price of building. The full amount consists not only of the procedure, but of the list of services necessary for its implementation.

The table shows the price of products and additional services in rubles.

The final processing and fitting of the tooth are already included in the cost of extension. After an initial examination with a dentist, you can find out the final cost of the procedure.
