Dental Crown in Dubai

Contraindications

Restoring teeth with crowns is an effective, safe, time-tested method. However, in some situations, it is not used. Here are the main contraindications.

Relative

The procedure should be carried out with special caution if the patient has:

• Foci of chronic inflammation in the tissues surrounding the tooth root – fistulas, cysts, granulomas;
• Root canals, the filling of which is done inadequately.

Crown installation is possible only after treating caries and other tooth and gum diseases.

The procedure is also not performed:

• During pregnancy and lactation;
• If the patient is under 18 years old – exceptions are possible, but a serious justification is required, and the decision remains with the doctor.

Absolute

The procedure is not carried out in the following cases:

• Allergy to metal – the dentist will try to offer an alternative solution, such as non-metal ceramics or E-max glass-ceramics;
• Occlusal anomalies, especially with the incisors of one row overlapping the other;
• Bruxism – spasms of the masticatory muscles, causing the patient to involuntarily clench their jaws, grind their teeth;
• Pathological mobility of teeth of the 3rd degree;
• Advanced periodontitis;
• Nervous, mental disorders that prevent the patient from adequately responding to the doctor's actions.

Which Crown to Choose for a Tooth

Several important factors are considered when choosing:

• Strength, durability of the material from which the prosthesis is made;
• How well its characteristics match the teeth that need to be replaced;
• Aesthetic properties;
• Cost.

Products made of zirconium dioxide are considered the best solution. They can be installed in the smile zone, used to replace chewing teeth. Non-metal ceramics are suitable for restoring front teeth units. During the consultation, the doctor will offer available options, talk about their features, advantages, and disadvantages.

Stages of Installing Dental Crowns

The installation is carried out in several stages, following consultation and preliminary preparation.

Visual Examination of the Patient

At the first appointment, the doctor examines the patient to assess the condition of the oral cavity and determine the extent of tooth decay, whether bite correction is needed, and whether there are signs of tooth and gum diseases that need to be treated. Additional diagnostics are ordered, usually including computed tomography (CT) and radiography. Some tests may be required. Diagnostics serve several purposes:

Preparation

The dentist takes impressions of the patient's teeth, which technicians in the laboratory will use to make crowns. They can also be manufactured based on images taken with CT and radiography. This approach allows for the creation of orthodontic structures of the necessary anatomical shape, ensuring they do not cause discomfort when used.

Before installation, it is necessary to:

• Treat caries and other diseases, eliminate inflammation in the oral cavity;
• Fill the root canals;
• Perform professional teeth cleaning to remove hard plaque and other deposits from their surface.

Directly before the procedure, anesthesia is administered. Local anesthesia is usually used, but general anesthesia or sedation can also be applied.

Nerve removal (pulpotomy) is not always performed. Modern dentistry suggests that it's better to preserve the neurovascular bundle to ensure full nutrition of the dental tissues. This way, the tooth under the crown will not decay and will function as a support for a long time.

Using a Post

This option is used if it is necessary to strengthen a severely damaged tooth. The post is a rod made of metal, carbon fiber, or fiberglass. It is inserted into the root canal, then fixed with dental cement. Active posts with threads, which are installed by screwing, are also used.

Using a Core Build-up

If the tooth is severely damaged and its tissues are insufficient for forming a core, an artificial substitute - a build-up - is used. It is fixed on one or several posts and serves as a non-removable prosthesis, over which the doctor places a crown.

Supported by an Implant

In this case, the surgeon first implants an artificial root – a metal rod capable of withstanding significant load – into the jawbone. The implant connects to the crown through a special intermediary element, the abutment. A screw connection is usually used.

When Crowns Cannot Be Placed

Orthodontic structures are usually not installed on severely damaged teeth. For example:

• The height of the remaining tooth above the gum is no more than 2-3 mm – the problem may be solved with a core build-up;
• The tooth is heavily affected by caries that has penetrated deep and reached the gum level;
• The teeth have lost stability due to periodontosis.
