CEREC or Chairside Economical Restoration of Esthetic Ceramics has revolutionized the design and placement of dental crowns. To understand CEREC crowns, it is essential to understand what a dental crown is.
What is a dental crown?
Dental crowns are tooth-shaped dental prosthetics that are mounted over damaged teeth to restore their natural shape, size, color, and function. They are used to:
- Protect damaged teeth from breaking.
- Fix broken, fractured, and cracked teeth.
- Cover teeth that have lost their structure to decay.
- Restoring the color of stained and discolored teeth.
Traditional dental crowns require two appointments over a period of 3 weeks with the dentist to get installed in place. The process is quite long and cumbersome.
What are CEREC crowns?
CEREC or same-day crowns use a trailblazing CAD/CAM technology along with an advanced milling machine to complete the crown placement procedure in sixty to ninety minutes. The usage of state-of-the-art technology allows the dentist to fabricate crowns with great precision and less time.
What are the benefits of CEREC crowns over traditional crowns?
- CEREC crowns are crafted using advanced technology, which enables the dentist to create crowns with great precision and care.
- They are more natural-looking and easily blend in with the neighboring teeth.
- The material with which they are made does not irritate the gums and rests comfortably in the mouth.
- CEREC crowns look and function like natural teeth.
Partial crowns are also known as inlays and onlays. When a patient suffers from tooth decay or damage that does not warrant an extraction but cannot be treated with standard fillings, in such cases, dental inlays and onlays or partial crowns help restore the teeth to their original strength. Inlays and onlays or partial crowns are nothing but a modified version of standard fillings. Also known as indirect fillings, the material required for inlays and onlays or partial crowns is prepared in a laboratory, unlike the conventional fillings. The structures are a go-to procedure when the patient needs replacement or removal of old fillings.
What is the difference between Inlays and Onlays?
The primary difference between inlays and onlays is their area of application. While inlays are applied to the inside of the cusps of the teeth, onlays are applied to the biting surface and can fill more than one cusp across the tooth. Generally, inlays are used for small areas, while onlays repair large areas. However, both inlays and onlays are manufactured using materials like composite resins, gold, or ceramics owing to their durability.
How are partial crowns placed?
As stated earlier, inlays and onlays are manufactured in a separate dental lab before applying them to the tooth. Due to the preparation required, the procedure is divided into two stages:
The first visit to the dentist involves cleaning the affected area. The dentist numbs the affected area by applying a local anesthetic. Following this, the affected area is drilled and cleaned to get rid of the decay or damage and to prepare the tooth for an inlay or onlay. The next step in the procedure is to take an impression of the cavity formed in the affected tooth.
There are two ways to get the mold of the damaged tooth. The basic and most popular way is to use dental putty and fill the cavity to get a perfect mold. The second way utilizes digital imaging to analyze the size and shape of the inlay or onlay that is to be manufactured. The images or the mold are sent to the dental laboratory, where an inlay or onlay is crafted that would exactly fit the patient’s tooth.
As stated earlier, inlays and onlays are crafted using a variety of materials. However, the most preferred material is porcelain owing to its color, which matches the natural color of the teeth. The dentist then creates a temporary restoration to protect your tooth until the inlay or onlay is ready.
During the second appointment, the dentist removes the temporary restoration and ensures that the inlay fits perfectly. If the inlay or onlay fits in the cavity perfectly, the dentist binds them using a strong resin adhesive. The final step of the procedure involves polishing the inlay or the onlay to ensure a pleasing aesthetic finish.
The patient does not feel severe discomfort or pain during the procedure. In case the patient suffers from acute pain, they can take over-the-counter medication to relieve the pain.
What are the benefits of partial crowns?
Partial crowns are preferred over metal fillings for the following reasons:
- They are durable: The material used in crafting inlays or onlays ensures their durability. The hard-wearing and robust materials make the inlays and onlays last for as long as 30 years.
- Provide increased strength: Metal fillings are known to diminish teeth power by 50 percent. However, inlays and onlays help increase teeth strength up to 75 percent.
- Prolong tooth life: Inlays and onlays are known to prolong tooth life. Furthermore, the procedure shields the patient from the need for dental treatment in the future.
