WHAT IS THE PURPOSE OF A DENTAL CROWN?
Dental crowns are used in aesthetic dentistry to cover teeth that have been injured, fractured, devitalized (dead), or badly deteriorated and no longer have enough good tooth structure to sustain a filling or a veneer. Crowns can strengthen and improve the appearance of these teeth, especially if several of their surfaces need to be replaced. The artificial crown is similar to a cap that is glued over a real tooth.
When it is still feasible to salvage teeth that have lost significant tooth structure but where the pulp is not damaged and a root canal treatment may be conducted, dental crowns are suggested. As a result, in order to consider crown implantation, the tooth root must still be “usable.”
Before the crown is placed, it is sometimes essential to create and install a post that is anchored in the root of the tooth. When the natural tooth structure is damaged as a result of a root canal, a post is also necessary. In these cases, the post is critical for the crown’s appropriate support.
Artificial crowns, like veneers, can repair a variety of minor dental flaws. They are used in a variety of contexts, including:
Restoration of decaying or fractured teeth, since they may fully cover a damaged tooth, as opposed to veneers, which just cover the front part of the teeth;
Teeth that have changed color over time, “dead” teeth (devitalized after a root canal), teeth with massive fillings, or malformed teeth;
Standardizing the color, form, and function of the teeth to improve the look of the smile.
ARTIFICIAL DENTAL CROWNS ARE A TYPE OF FIXED PARTIAL DENTURE.
THE BENEFITS OF CROWNS
They have the same aesthetic look and function as genuine teeth.
They are as robust and solid as real teeth and let you to eat virtually properly.
Unlike removable dentures such as complete or partial dentures, they are permanently bonded (cemented) in the mouth. They are more stable than other forms of dentures because they are fastened in the mouth.
CROWNS IN DIFFERENT STYLES
There are three types of dental crowns that are commonly used, each with its unique production method:
Ceramic-metallic crown; composite resin crown; ceramic-ceramic crown
The yellow gold crown is still in use, though it is rarely seen. Because it is not aesthetically pleasing, it is typically put on posterior teeth that are not visible when a person grins. It is, nevertheless, highly resistant and does not wear down the opposite arch’s teeth.
THE METALLIC-CERAMIC CROWN
The metal-ceramic crown is made up of two unique materials: a metal alloy for the base (also known as the “skeleton” of the crown) and ceramic for the primary prosthesis.
The ceramic-metal crown is extremely durable, implying that it will last a very long time. It is chosen when the operating conditions are more complex and other crown production techniques are ineffective. It is also less expensive than other forms of crowns.
The downside of this style of crown is that the metal base shows through when the gum wears down and resorbs over time, which is regarded unattractive.
The visual consequences of crown installation are mostly determined by the material utilized to create it. Some materials cost more than others.
Because the injured tooth must be ground down to make room for the crown, crowns are an irreversible procedure.
