Installation of a dental crown

Igor Osadchiy Articles 03.02.2025 7 min 22
Installing dental crowns is an important dental procedure designed to restore the functionality and aesthetics of teeth. It may be necessary in cases of significant tooth damage, after caries treatment, due to trauma, or certain bite pathologies. There are many types of dental crowns that need to be carefully considered before making a decision.

Dental crown installation in modern dentistry: goals and objectives

An artificial dental crown is a construction used to restore the shape, function, and aesthetics of a damaged or lost crown part of a tooth.

Crown installation aims to achieve the following goals:

  • Restoring tooth structure.

In some cases, installing a crown is necessary to prevent further destruction, for example, after removing large carious cavities or pathological wear;

  • Improving aesthetics.

Artificial crowns help conceal various defects (color changes, chips, slight crookedness, etc.);

  • Restoring functionality.

Crown installation is directly related to restoring chewing function and is necessary for proper load distribution across all teeth;

  • Stabilizing the dental arch.

Installing dental crowns on implants or prepared teeth can prevent shifting of adjacent teeth and help maintain proper bite.

Dental crown installation: indications

The practice of widespread use of artificial crowns in dentistry has existed since the beginning of the 20th century. The construction is not accidentally popular: it has not only a wide range of applications but also a long list of indications.

Dental crown installation: indications

Name Description
Deep caries Crown installation is necessary to restore the lost tooth structure when caries has led to significant destruction of the crown part (30% or more)
Root canal diseases Endodontic treatment (root canal treatment) often requires significant removal of crown part tissues. In such cases, installing an artificial crown instead of a large filling is recommended to preserve the tooth and protect it during chewing loads
Fractures and cracks A crown is indicated for cracks, fractures, or other mechanical damage that may threaten tooth integrity
Aesthetic improvement request A crown conceals various defects: changes in color, shape, size, etc.
Deformity correction In cases of tooth development anomalies such as dysplasia and fluorosis, crowns help restore proper shape and size
Prosthetics after tooth loss Used in implant-based prosthetics
Wear prevention Indicated for protecting severely worn teeth, especially in cases of bruxism and/or pathological wear
Malocclusion Crown installation can help with bite correction by restoring dental arch functionality

Contraindications for dental crown installation

Despite the fact that artificial crowns can perform a number of tasks and solve a whole range of dental problems, there are also limitations to their use. Many patients strive to save the tooth at any cost and insist on crown installation, but there are contraindications where crown use is impossible or inappropriate.

Name Description
Unstable periodontal tissue Mucosal diseases such as periodontitis can lead to tooth loss. If periodontal tissues are inflamed or severely damaged, crown installation will not solve the underlying problem and may lead to further complications
General medical contraindications Some systemic diseases (e.g., severe cardiovascular diseases, diabetes, oncological diseases) can make the crown installation procedure risky. In such cases, prior consultation with the appropriate physician is required
Improper tooth positioning If teeth are positioned incorrectly or significantly shifted, this can complicate crown installation and cause bite problems. In such cases, orthodontic treatment before crown installation may be required
Psychological factors Some patients may have mental disorders or phobias related to dental procedures, making crown installation inadvisable

Classification of artificial dental crowns

By material:

  • Metal-ceramic crowns: consist of a metal base and ceramic coating.
  • Ceramic or press-ceramic crowns: made entirely from ceramics.
  • Zirconia crowns: made from zirconium.
  • Metal crowns: made entirely from metal (usually gold or special alloys).
  • Composite crowns: made from composite materials that can be colored in various shades.

By construction:

  • Solid crowns: made from a single material that fully covers the tooth.
  • Layered crowns: consist of different materials, such as metal-ceramics, where the metal base is covered with ceramics.

By manufacturing method:

  • Traditional crowns: manufactured in a dental laboratory based on impressions or tooth models.
  • CAD/CAM crowns: created from special blocks using computer modeling and milling.
  • Mock-up crowns: made from fast-setting medical polymer by the prosthodontist directly in the office.

By indication for installation:

  • Permanent crowns: installed on teeth for long-term restoration of their function and aesthetics.
  • Temporary crowns: used for temporary tooth restoration before permanent crown installation.

By area of application:

  • Crowns for front teeth.
  • Crowns for chewing teeth.

Advantages and disadvantages of different types of crowns

Metal-ceramic crowns.

Advantages:

  • Strength: the metal base provides high strength and durability, crown installation on living teeth is available.
  • Aesthetics: ceramic coating allows achieving a natural appearance and matching color.
  • Wear resistance: possess good operational characteristics and are resistant to mechanical loads.

Disadvantages:

  • Transparency: unlike fully ceramic crowns, metal-ceramics may be less transparent, which can negatively affect aesthetics when installed on front teeth.
  • Corrosion: the metal base may be subject to corrosion over time.

Ceramic crowns.

Advantages:

  • Aesthetics: have a very natural appearance due to good transparency and can be colored in various shades.
  • Biocompatibility: ceramics do not cause allergic reactions.

Disadvantages:

  • Cost: generally more expensive compared to crowns made from other materials.

Zirconia crowns.

Advantages:

  • Strength and durability: zirconium has high strength, making crowns very resistant to mechanical loads.
  • Aesthetics: have high transparency and natural appearance, making them suitable for both front and chewing teeth.
  • Biocompatibility: do not cause allergies.

Disadvantages:

  • Installation difficulties: due to material rigidity, installation may require greater precision and skills from the doctor.

Metal crowns.

Advantages:

  • Strength: high strength and durability.
  • Wear resistance: resistant to wear and handle loads well.

Disadvantages:

  • Aesthetics: metal crowns have a characteristic color and are very noticeable in the mouth.
  • Potential allergic reactions: some patients may experience allergic reactions to metal components.

Composite crowns.

Advantages:

  • Cost: generally less expensive compared to ceramic and zirconia crowns.
  • Aesthetics: possibility to choose color and texture.

Disadvantages:

  • Fragility: less strong and wear-resistant.
  • Color change: tend to lose color.

  • examination and diagnostics;
  • tooth preparation;
  • impression taking;
  • temporary crown installation if necessary;
  • manufacturing;
  • permanent crown installation.

Advantages: durability and ability to choose various materials (metal-ceramics, zirconia, ceramics).

Disadvantages: requires several visits and temporary crown installation.

CAD/CAM dental crown installation technology: involves using computer technologies for crown design and manufacturing.

Crown installation stages:

  • examination and diagnostics;
  • tooth preparation;
  • tooth scanning with 3D scanner or impression taking;
  • temporary crown installation if necessary;
  • computer crown modeling;
  • manufacturing;
  • installation.

Advantages: fast manufacturing, high precision, and comfort.

Disadvantages: cannot be used in case of complete tooth absence.

Dental crown installation: pricing

The price of dental crown installation varies depending on the region, type of crown, and chosen clinic. In Kyiv, for example, the price of crown installation is higher than the national average due to higher levels of service and specialist qualifications.

On average, dental crown installation prices across Ukraine range from 13,000 to 20,000 hryvnias. The cost of metal-ceramic crown installation may be lower than fully ceramic or zirconia crowns. It should also be noted that crown installation prices in Kyiv may include additional costs, such as temporary crown installation or dental consultation.

The price range for dental crown installation in Kyiv is as follows: metal-ceramic — 10–15 thousand hryvnias, ceramic — 15–20 thousand hryvnias, zirconia — 13–19 thousand hryvnias, metal — 3–5 thousand hryvnias, temporary composite — 3.5–4 thousand hryvnias.

Questions

Yes, in cases of significant damage, a high degree of destruction, or bite dysfunction, installing crowns on all of a patient’s teeth is possible.

A turnkey crown installation involves performing all stages of crown installation in one clinic: from the initial examination to the final result verification.

Crown installation is usually not painful as it is performed under local anesthesia. The tooth preparation process may cause minor discomfort, but overall the procedure is painless.

Manufacturing and installing crowns takes from one to several visits. With the traditional method, the process may take 1–2 weeks.
