What is better - a filling, an inlay or a crown to restore a tooth?

In this article, we will consider situations when a filling can be installed on a tooth, and in which cases it is better to give preference to a ceramic tooth inlay.

Caries is the most common dental disease for which people go to the dentist. It is ideal if it is possible to identify caries at the earliest stage of its development. But this is not always possible for various reasons. Caries occurs not only on a tooth that has not been treated, but secondary caries can also develop under a previously installed filling. Sometimes this destructive process develops so secretly that it is simply impossible to visually determine it yourself. Meanwhile, tooth tissues are affected more and more over time. In order to prevent such development of the disease, it is necessary to regularly use dental services for preventive examinations once every six months. A specialist during an examination will always be able to identify the presence of a disease using a visual examination and various modern methods of x-ray diagnostics.

The classic restoration of a tooth after treatment is the placement of a filling in a prepared cavity. But this method is good if there is a small cavity. When most of the tooth is destroyed, it is better to restore such a tooth with a ceramic inlay.

How does an inlay differ from a filling?

The filling is made of a plastic material that hardens and takes the desired shape. It is made and installed right in the dentist's office in one appointment. However, a filling will not help when the tooth is severely damaged. In this case, you will need a ceramic inlay. It is made in the laboratory using an individual impression. It not only closes the resulting cavity, but also exactly repeats the shape of the destroyed area of ​​the crown.

Advantages over fillings:

• Higher efficiency
  . It is possible to restore a severely damaged tooth. A filling is suitable only if the cavity occupies less than a quarter of the crown, and an inlay can restore from 25 to 60%;
• Naturalness
  . The inlay imitates the anatomical shape of the chewing surface. It is almost invisible, while the filling can be seen;
• Higher strength
  . Microprostheses do not develop cracks. A filling of this size would quickly crumble, so it is not suitable for restoring extensive damage;
• Durability
  . The tab will last 5–7 years. At the same time, it will remain unchanged and will not lose its original characteristics;
• Ensuring the prevention of secondary caries
  . Sometimes the filling can become infected again. The insert fits very tightly and does not shrink over time, so this risk is eliminated;
• Color fastness
  . The fillings have a porous structure, so they are easily stained by tea, coffee, and tobacco. Ceramics are not subject to color changes.

Flaws:

• They cost more;
• They take longer to produce. The filling can be placed in one visit to the dentist. And to install the tab, you will need 2 visits with a break for the manufacture of a microprosthesis in the laboratory.

Advantages and disadvantages of using stump inlays

The main advantage of stump pin inlays is the high reliability and durability of prosthetics. This design will firmly hold the installed dental prosthesis and, moreover, will allow for proper distribution of the chewing load. When using pin stump inlays, the risk of crown loss is reduced to zero.

Installing crowns on the stump inlay and pin allows you to increase the useful life of the prosthesis. In addition, core inlays help to obtain the ideal tooth shape and are suitable for restoration of anterior and chewing teeth.

There are only two disadvantages to the use of stump inlays - higher price and longer prosthetic time. On average, it takes about 2 weeks to make an inlay.

IMPORTANT: Only an experienced prosthetist can make a high-quality multi-root collapsible stump inlay. Therefore, it is so important to choose a clinic for your treatment that employs competent and qualified orthopedists and dental technicians and has its own, well-equipped dental laboratory. Our dentistry in Moscow, Firadent, 100% meets these conditions: your treatment with us will be carried out with impeccable quality and comfort!

Indications

The main use case is the treatment of caries. A ceramic inlay for a tooth is needed if its crown is destroyed by 25–60%. If the cavity occupies less than a quarter of the surface, then you can get by with a filling, but if more than 60%, then a crown is needed. Other indications for installation:

• Destruction of non-carious origin;
• The need to install a bridge prosthesis (microprostheses are placed on abutment teeth to increase their strength);
• Increased abrasion of enamel.

Contraindications

This type of microprosthesis cannot be installed in the following cases:

• bruxism (grinding teeth in sleep);
• steep slopes of hillocks;
• rapidly progressing caries;
• deep cavity extending into dentin;
• inability to ensure complete dryness of the field.

A relative contraindication is poor oral hygiene. In what cases is it not advisable to use:

• A cavity less than 1.5 mm deep (you can get by with a filling);
• The damage has affected the cervical area of ​​the tooth (the inlay will no longer help);
• The tooth is more than 60% destroyed (a crown is required);
• Milk tooth. It makes no sense to restore it using an inlay, since the life of the tooth is less than the durability of the microprosthesis. In addition, a vlkadka costs much more than a filling. Spending so much money to restore a tooth that will soon fall out is not advisable.

When is a filling needed?

If less than a third of the tooth is damaged, then in most cases the doctor restores it using filling materials. Modern photopolymer fillings
allow you to recreate the shape and color of a natural crown, add aesthetics to the surface, and adjust the position of the unit.

But in case of serious damage, a large filling is often (!) placed in the cavity, which will not withstand long-term significant loads. If a tooth has been depulped, then over time its walls become fragile and further destruction occurs. When the carious cavity is large, restoring the destroyed tooth crown with a regular filling is acceptable, but does not guarantee long-term preservation.

Types of tabs

Depending on the material of manufacture, they come in the following types:

• metal-ceramic
  - the most budget-friendly;
• ceramic
  – the most aesthetic;
• made of zirconium dioxide
  - the most durable.

These microprostheses are also classified depending on their position in the tooth. According to this criterion, the following varieties are distinguished:

• Inlay
  – the hole in the tooth is box-shaped, the inlay is installed inside it;
• Onlay
  – the overlay has an external side;
• Overlay
  – only one wall is preserved, the overlay replaces almost the entire crown;
• Pinlay
  – the inlay has additional cavities or pin inclusions for better fixation.

The type of inlay based on its position in the tooth is selected by the dentist after an initial consultation.

Types of products

Experts distinguish between two main types of orthopedic structures: stump and restorative. A ceramic core inlay is required to restore the tooth core for subsequent fixation of the crown. Most often it is used for prosthetics of incisors. Restorative structures are used for chewing teeth when one or two surfaces are damaged. In addition to high aesthetics, they are characterized by reliability and durability. Also, the tabs are distinguished by the material used. Below are the most common materials from which products are made.

• pressed ceramics. Products are produced using porcelain injection molding. The procedure is carried out under conditions of high temperature and pressure. Compared to orthopedic structures made of metal or zirconium dioxide, they are not as durable, but are ideal from an aesthetic point of view;
• zirconium dioxide. They are made by grinding finished metal oxide blanks. Grinding is carried out automatically using a ready-made impression (plaster model) of a damaged molar or premolar. Thanks to computer control, finished structures are characterized by high quality. Upon completion, the workpiece is fired, fusing the porcelain mass. Zirconium dioxide is a high-tech material for orthopedic structures, and therefore is in special demand. From an aesthetic point of view, such inlays are in no way inferior to porcelain products, and in terms of strength they are not inferior to metal products;
• metal. The metal most often used is gold or a silver-palladium alloy. Such designs are reliable, but do not have high aesthetics;
• metal ceramics. This is the latest orthopedic design, which is distinguished by high aesthetics, but at the same time cannot boast of proper quality. Due to thermal exposure, such products often fall out of the mouth. Most experts advise installing a structure made of zirconium dioxide or pressed ceramics rather than metal ceramics.

The process of manufacturing and installing inlays on a tooth

Dental prosthetics is performed in several stages:

1. Initial consultation
   . The doctor assesses the extent of destruction and draws up a recovery plan;
2. Hygienic teeth cleaning
   if necessary;
3. Selection of the required shade
   to match the enamel color;
4. Removal of tissues affected by caries
   , if the destruction was caused by this disease;
5. Taking an individual impression
   , according to which a microprosthesis will be made;
6. Closing the cavity with temporary material
   for the waiting period;
7. Making an inlay
   based on an individual impression in a dental laboratory;
8. Installation
   of the inlay and its fixation using special dental cement.

Thus, a tooth can be restored in 2 visits to the clinic. The first visit is a consultation, treatment of caries and taking an impression, the second is the actual installation.

Tooth restoration with a crown using metal-ceramics

An inexpensive solution is a one-piece tooth crown. It is durable and justified for molar prosthetics. The durable frame is covered with layers of ceramics. This design is aesthetic and convenient.

Tooth restoration with a metal-ceramic crown is a budget-friendly and reliable way to maintain the health of your teeth. The cost of a crown is 17,900 rubles per tooth. An impression is made that follows the contours of the natural crown, recording the characteristics of the bite, and a frame is created according to the obtained parameters. Each applied layer of porcelain coating is baked under high temperature.

If there is no healthy root, the tooth has long been removed, there are problems with the structure of soft and bone tissues, then the only way to return to your normal lifestyle and maintain health is implantation. Today there are methods for restoring a tooth crown, completely replacing a lost unit - in my clinic the cost of metal-free options is from 27,900 rubles

for a destroyed restored tooth (and
from 34,900 rubles
for a crown for an implant).

I, Dr. Samsakov, will produce ceramic tooth modules of any complexity, post-core and other types of inlays, “crown plus tooth root” modules using CEREC technology - cost from 27,900 rubles. per tooth The process will take about 1.5 hours.

Pros of ceramic inlays

A ceramic tooth inlay has many advantages:

1. High strength
   . An inlay, unlike a filling, significantly strengthens the tooth. Therefore, it is the preferred option if the tooth in which it is installed will be used as a support for a bridge;
2. Good aesthetic properties
   . Ceramics are translucent, so they successfully imitate the natural color of the tooth. It also exactly follows the normal shape of his crown;
3. The ability to fully restore the chewing surface
   . The inlay completely follows the anatomical shape of the tooth. This provides convenience when eating;
4. Hygiene
   . Glaze is applied to the tab as a finishing layer. It creates a glossy surface on which plaque does not accumulate;
5. Resistance to external factors
   . Ceramics does not darken over time, does not change color due to smoking or drinking coloring drinks;
6. Durability
   . A ceramic inlay will last longer than a filling – 5–7 years. There are also more durable inlays, for example, made of zirconium dioxide, but ceramic ones are more aesthetically pleasing compared to them;
7. No risk of secondary caries
   . Inlays, unlike fillings, do not shrink and adhere tightly to the tissue. This eliminates the possibility of cracks and the development of secondary carious lesions;
8. Easy replacement
   . When installing a new inlay after its service life has expired, there is no need to grind the tooth again. Caries does not develop under a microprosthesis of this type, so there is no need to remove the affected tissue.
9. Bioinertness
   . Ceramics does not absorb or accumulate any odors. There is no plaque deposited on it;
10. Hypoallergenic
    . Microprostheses made of pure ceramics do not cause any immune reactions;
11. No need for special care
    . Regular hygiene rules are sufficient.

Indications and contraindications for installation

Indications for tooth restoration using a ceramic microprosthesis:

• The need to restore chewing teeth that have a significant cavity formed as a result of caries or trauma, when it is impossible to eliminate the defect with filling. The technique is perfect even in cases where it is necessary to restore up to 50% of damaged tooth tissue.
• We are talking about replacing old large fillings. The need for tissue preparation, which involves the refilling procedure, will further enlarge the existing cavity and thin the walls of the tooth. Under such conditions, installing a new seal will not ensure reliability.
• There is a pathological abrasion of tooth tissues and, as a consequence, their destruction. Ceramics, which have increased strength, can completely prevent the loss of hard tissues due to their abrasion.
• Cases where the destruction of the coronal part of the tooth is great, it is possible to avoid depulping and covering the tooth with a crown.

You will have to refuse to use a ceramic inlay in the following cases:

• More than half of the destroyed tooth tissue needs to be restored. In this case, the only possible solution to save the tooth and avoid its removal is filling and subsequent installation of a crown.
• We are talking about baby teeth or numbers of eights. With such extensive damage to the wisdom tooth, surgical tactics are taken as the basis; removal will be required.

The main differences between a filling and a ceramic inlay

A ceramic inlay differs from a filling in a number of ways:

• The material from which ceramic inlays are made is similar in physical and chemical properties to natural tooth tissue, due to which microprostheses are significantly superior to any type of filling in terms of strength and resistance to abrasion.
• Regarding aesthetics, the ceramic inlay looks completely identical to the tooth tissues, matching them in color and transparency. At the same time, the filling may have a different shade.
• The inlay is used to restore chewing teeth with significant tissue defects. The filling is used for small, no more than 30%, affected areas, which is associated with insufficient hardness of the material. If you try to install a larger filling, it will not be possible to ensure a sufficient quality of its fit, which will lead to the risk of reoccurrence of caries. At the same time, if all preparatory measures were carried out correctly, a ceramic onlay will reliably avoid such complications.
• In terms of service life, ceramic inlays have clear advantages. If a filling guarantees preservation of the result for about 5 years, then with the help of a microprosthesis you can expect that the tooth will last over 10 years.
• If a filling is made directly in the patient’s mouth by a dental therapist, then ceramic microprostheses are created in the laboratory, and the entire process is controlled by an orthopedic dentist. The course of treatment takes longer, but thanks to the technological features of the technique, the specialist has the opportunity to install a microprosthesis more tightly than a filling.
• The method of restoring a tooth using a ceramic inlay is more expensive. However, this conclusion is not absolute, since in the long term the patient receives a more reliable and durable restoration result.

Types of tabs

Today, the most popular classification of ceramic inlays, developed by the American Dental Association ADA, is considered. According to it, the following types of tabs are distinguished:

Inlay – a microprosthesis is fixed inside the tooth. In this case, restoration of the tubercles is not expected; the tab is, as it were, sandwiched between them. Such features ensure its high functional performance and viability. However, these clinical prerequisites make it possible to use a filling quite successfully, so specialists take an extremely balanced approach to choosing an inlay.

Onlay - this option of an inlay is used if one or more cusps of the tooth are destroyed and need restoration. By using an inlay, some of the cusps on the tooth remain their own, and some are replaced with a ceramic microprosthesis. However, when carrying out a chewing load, an overturning moment may occur, which negatively affects the fixation of the structure. Only a specialist’s impeccable knowledge of the anatomy of the dentofacial system, thorough diagnostics and impeccable precision in the execution of work can ensure the required quality of restoration carried out using this method.

Overlay is an option in which the inlay covers all the cusps of the tooth, which ensures maximum fastening strength. In such a clinical case, the doctor will be faced with a dilemma whether to use an inlay or perform additional grinding of the tooth and install a crown.

Pinlay is a special version of the inlay, which involves the presence of a pin in its design, with the help of which better fixation of the entire structure is ensured. This option is suitable for any type of inlay, on any tooth.

How a ceramic inlay is created for teeth

The production of a ceramic inlay goes through several stages:

1. If necessary, the doctor removes the remains of old fillings, damaged tooth tissue, smoothes the walls of the cavity, which will ensure high-quality impressions and, in the future, a tight fit of the inlay. Then the resulting cavity is treated with medication.
2. Taking an impression. Since the inlay is a microprosthesis, it is to the dental laboratory that the finished impressions are sent.
3. The laboratory stage assumes that, based on the impressions obtained, the dental technician casts a plaster model, and then restores the lost part of the tooth using ceramic mass. The process consists of applying the material in thin layers and sequential firing in a special oven, where, in addition to high temperature, about 700 degrees, vacuum conditions are created. The color of the ceramic microprosthesis is selected individually, taking into account the basic tone of the patient’s enamel. The created product is carefully polished and handed over to the doctor. The use of ultra-precise technology and computer modeling techniques allows us to take this technology to a new level, significantly increasing the quality of the resulting product and the compliance of the microprosthesis with the cavity being restored. When creating an e.max Press ceramic inlay, standard impressions are not required. The doctor will receive the necessary information by scanning the tooth, nearby and opposite areas using a compact 3D camera. The software will be used at each subsequent stage, when creating a virtual model of a tooth, an inlay, as well as when turning a real model on a special milling module connected to a computer. By making an inlay using this method, using computer technology, the impeccability of the result will be guaranteed.
4. At the patient’s subsequent visit, the doctor tries on the finished microprosthesis. The specialist evaluates the fit of the tab and the contact with neighboring teeth. If no modification is required, attach it to the tooth using adhesive material.

Considering this entire multi-stage technological process, it becomes clear that such a complex design cannot be used inexpensively. In addition to direct manufacturing and payment for the services of a dental technician, the cost of diagnostics, tooth processing, taking impressions, selection of shape and color, and the purchase of expensive materials and ceramic mass are also involved in determining the price. Will increase the final cost and use of digital technologies.

Advantages and disadvantages of products

Ceramic inlays are significantly superior in quality to composite fillings. And this is due, on the one hand, to the physical and chemical properties of the material, and on the other hand, to the peculiarities of creating microprostheses. Based on these features, the advantages of ceramic inlays are:

• High manufacturing precision, which minimizes the risk of developing recurrent caries, guarantees the reliability of restorations and extends the life of the tooth. In fact, the inlay and the tooth become one. As a result of life activity, your own enamel is more likely to be destroyed than a ceramic inlay.
• Excellent aesthetic characteristics. Inlays are exactly identical to natural tooth tissue in appearance.
• High wear resistance. Ceramics are not subject to staining with food dyes and exposure to aggressive substances in the oral cavity.
• Lack of special care. It is enough not to ignore daily standard hygiene procedures and visit the dentist in a timely manner for a preventive examination and professional teeth cleaning.

Where is the best place to install ceramic inlays?

Considering the high costs of installing a ceramic inlay, the question of where it is best to carry it out is not idle. To fully obtain an aesthetic, reliable and long-term result, you need to use the services of the most qualified specialists who have extensive practical experience in installing such orthopedic structures. The specialists of the Dental Studio clinic in Moscow are the best solution.

Our dentists constantly, every day, prove their professionalism with the high-quality results of their work. Success is fully guaranteed when installing ceramic inlays. Using this technique, you can extend the life of a decayed tooth without installing a crown.

Types of ceramic veneers

At the moment, there are two types of ceramic veneers - from pressed ceramics and from ceramics made using a refractor. Essentially they have no differences, but they are installed and processed differently. Let's look at how ceramic veneers are made:

Pressed ceramic veneers

This method of making veneers involves first making a wax model, on the basis of which ceramics are pressed under high pressure. This allows you to very accurately convey all the features of the appearance of the patient’s tooth enamel and make the inside of the veneer exactly adjacent to the tooth.

Veneers made using a refractor

When manufacturing using a refractor, a special refractory base is first made, onto which ceramics are applied in layers, and then this structure is baked in a special oven.

IMPORTANT:

Specialists at the German Implantology Center can produce ceramic veneers of any type. Any veneers are made individually for each patient, and the quality of their installation meets the highest standards.
