Dental crowns
Dental crowns extend the life of teeth with significant damage. After repeated restorations, they cannot be restored with inlays. Dental crowns are fixed dentures that are put on top and fixed to the dental part with cement. They are created similarly to the natural element - the shape, enamel color and texture are identical.
When do you need a dental crown?
Crowns are indicated in the following cases:
- 50% or more of the tooth tissue is affected by decay;
- Cracks and damage are present;
- Significant changes in the color of enamel;
- Significant wear and tear on the enamel;
- Significant aesthetic defects (malpositioning, distortion).
Crowns allow for the correction of aesthetic defects and enhancement of the functional capability of the teeth.
Crowns are not placed under the following conditions:
- Age under 16 years of age;
- Gum disease;
- Thinning enamel (usually found on lower frontal teeth).
Types and advantages of dental crowns
Dental prosthodontists during the development of the denture industry used a variety of materials to produce crowns. These were miniature metal dentures, titanium, plastic, sprayed and composite dentures. In modern dentistry, metal-ceramic, metal-plastic and metal-free crowns are popular.
These advanced products for protecting teeth do not cause allergies and do not have a negative impact on the gums. Crowns fit perfectly on the tooth surface and look natural.
Metal-free crowns are available in several designs.
- Pressed ceramic. Teeth made of this material have a natural look, texture and shine. The tooth row of dentures and its own elements looks identical, so a beautiful smile for the patient is guaranteed. The disadvantage of ceramics is their brittleness, which is why they are not placed on chewing teeth. Such crowns are placed on the frontal teeth. If used with care, they can last more than 15 years.
- Dioxide-zirconia crowns. These crowns are very durable, so they are suitable for placement on occlusal teeth. The application of this type of crowns does not require the teeth to be prepared, and they last for more than 20 years, making them look natural. An additional advantage is their use in dental bridges.
- Aluminum oxide crowns. This is an innovative material that looks the most aesthetic compared to other types. They are characterized by low strength, so they are placed on the front teeth. Aluminum oxide crowns have no contraindications. They are non-allergenic and have a long service life.
- Metal-plastic crowns. Products are made from nickel, chromium, cobalt compounds and are covered with plastic.
Metal-ceramic miniprostheses are made of the same material as metal-plastic crowns, only the top is covered with ceramic. The metal frames, which are translucent, are hidden by the ceramic shoulder mass. Such designs are considered temporary. The lifespan of these crowns is limited due to their increase in size and change in shade.
In orthopedic dentistry, it is customary to classify crowns according to the surface area they occupy. They can be full crowns (telescopic, with pins) and partial crowns (equatorial, final, three-quarter, half-crowns).
The process of dental crowns installation
Prior to the placement of crowns, the dentist performs a comprehensive examination of the patient's oral cavity. Based on the results of the examination, the dentist draws up a treatment plan, identifies contraindications and advises the patient on the choice of the type of structures. The orthopedist-dentist makes an X-ray of the jaws, which assesses their condition. If any irregularities are detected, treatment procedures are prescribed, and tartar and plaque are removed. The next step is preparing the tooth - the nerve is removed, the root canals are filled, and the tooth is grinded down to fit the crown. Grinding takes about an hour, as the dentist removes the tissue in layers and reshapes the tooth. The step is completed by taking an impression of the tooth and transferring the impression to the lab for fabrication of the crown.
Dioxi-Zirconia restorations are designed and fabricated using CAD/CAM technology. The information is transferred to the milling machine where the crown is made. This innovative method makes it possible to obtain high-precision designs.
The next stage is characterized by a fitting of the crown. If the denture fits the parameters and the patient has no complaints, the restoration is cemented in place. Sometimes a temporary fit can be made to study the results, and then the crown is placed permanently.
The stages of fabrication and placement of the dental crown last from 5 days to 2-3 weeks. The period depends on the patient's oral problems, type and complexity of the treatment. During the treatment process, the patient is fitted with plastic dentures. All manipulations are performed under anesthesia - the patient will not feel pain or discomfort.
When is dental crowns contraindicated?
Dental crowns are prohibited in the following cases:
- identification of chronic periodontal disease;
- bruxism;
- weak tooth enamel;
- small teeth;
- abnormal bite and placement of the teeth.

It is worth restoring a lost tooth as early as possible, because delaying such a process can lead to unpleasant health consequences and undesirable costs in the future.
Patients who seek help for tooth loss too late unwittingly start the process of destruction of other adjacent teeth, because the load during chewing is not evenly distributed.
Dental implantation is one of the most reliable and effective procedures that allows you to restore one or more teeth.
The method of dental implantation is now very popular, because it helps patients to restore lost teeth both in the upper and lower jaws without grinding pine teeth, which is always carried out during prosthetics (crowns).
With implantation, the number of lost teeth does not matter. Dental implantation is considered to be the only right way out of care for everyone, because the healing rate of implants today is over 99%!
