What is a dental crown and when is it used?
A dental crown is a prosthetic restoration that imitates the shape, color and size of a tooth. Its purpose is to restore the lost function of the teeth, to return each tooth to a perfect condition, and in combination with implants, rehabilitation is also possible for patients who are completely toothless. Therefore, the installation of dental crowns is used as a permanent solution for large fillings, caries, tooth crown fractures, as well as in cases of distinct tooth irregularities, in places where you are missing teeth or in patients who are completely toothless.
The dental crown is combined with both veneers and bridges, depending on the needs of the patient. That is why it is very important that the doctor and the patient decide together what is best for the patient and only then the work is started.
Types of dental crowns
Dental crowns used in modern dentistry can be ceramic or metal-ceramic. Ceramic crowns are made only of high-strength ceramic materials, namely zirconium dioxide (ZrO2).
Metal-ceramic crowns are made of metals – chrome, molybdenum and palladium. Metal is less expensive, stronger and easily joined with ceramics.
However, ceramic metal-free zirconium crowns have an advantage due to the complete absence of allergic reactions, and they also have an advantage when choosing a color because zirconium can be dyed in any desired color.
The process of making dental crowns
Crowns can be made by hand in a laboratory or in a CEREC machine. The advantage is making the crown in CEREC machines because the crown is created on the basis of a 3D scan and thus we get maximum precision.
The procedure of installing dental crowns involves grinding the teeth and taking an impression. Dental crowns can take 7 to 10 days, during which time the patient wears temporary acrylic teeth that allow him/her to perform normal daily activities.
Making crowns in a CEREC machine allows everything to be completed in one day.
The crowns are permanently fixed on the dental supports, they do not come off and enable the normal functioning of chewing and speaking.
Durability of dental crowns
The durability of dental crowns depends on many factors, such as the experience and skill of the dentist, properly ground teeth, oral hygiene, and the quality of the material.
When a large number of teeth are missing or the existing ones are in poor condition, various types of prostheses are suggested.
FAQ
Let’s answer your most frequently asked questions.
With metal-ceramic crowns, the base is a metal alloy on which a ceramic coating is applied to hide the metal for aesthetic reasons. Due to aging and other physiological changes, there is a possibility that gray marks may appear on the contact between the crown and the body of the tooth.
This cannot happen with a metal-free crown because the inside of the crown is made of tooth-colored ceramic materials.
If you have healthy teeth, but you are not satisfied with their color, appearance, or one of them is irregular or chipped, you are a candidate for this type of therapy.
With proper maintenance of dental hygiene, crowns can last over 20 years.
