A dental crown is the most effective way to save a tooth if it is worn down, cracked, or chipped. A crown helps to preserve the natural tooth's size, shape, and strength. Metals, porcelain, resin, and ceramics are among the most common materials used to make dental crowns. Another optional material, zirconia, has grown in popularity as a material for dental restorations. Zirconia crowns are made from zirconium dioxide. Its ceramic properties, as well as the fact that it is milled from a single block, make it a strong dental prosthetic. The procedure for placing a zirconia crown is essentially the same as for a traditional crown.
During the first appointment, the dentist prepares the tooth by removing any decayed or damaged areas of the tooth. After that, impressions of the prepared teeth are taken. Your new restoration is then created by a trained technician based on your unique oral anatomy. The tooth will be prepared by your dentist by removing the temporary crown and cleaning the surrounding area. Dental cement will be used to attach the crown to your natural tooth. Once it’s in place, your dentist will make any minor adjustments needed to ensure that it fits your bite comfortably.
Types of Zirconia Crowns:
There are three types of zirconia crowns available: solid zirconia, layered zirconia, and high translucent Zirconia:
- Solid zirconia, also known as “monolithic zirconia” is more stable than high translucent zirconia, making it more resistant to the impact of chewing forces. Monolithic restorations are best placed in the back of the mouth due to their high opacity. It’s also great for covering up darkened dental preps from previous dental treatments, like a post and core or an implant-supported restoration.
- Layered zirconia is more translucent and opalescent, making it ideal for anterior crowns. These layered porcelains provide the realistic translucence required for front teeth restorations. Lithium disilicate ceramic is layered on top to create layered zirconia. Both solid and layered zirconia crowns have the same strength and consistency as traditional restorations, but these have far better aesthetics.
- High translucent zirconia is much more durable than porcelain-fused-to-metal (PFM) restorations, while still retaining a natural, vibrant translucency. High translucent zirconia saves the patient’s time because no shading liquids or drying time is required. Restorations will always appear natural due to their inherent natural fluorescence under any lighting condition.
Several factors influence deciding which type of crown is right for you. These considerations include the location in your mouth where the crown will be implanted, the condition being treated, as well as your individual lifestyle and budget.
The advantages of zirconia dental crowns:
- Zirconia crowns do not contain any metal, making them biocompatible. This means they are less likely to cause the body to react or produce an immunological response such as inflammation.
- You won't have to worry about developing the common grey line around the edge of the tooth that is often seen with porcelain-fused-to-metal crowns.
- Zirconia crowns are strong enough to withstand the impact of chewing and biting forces applied by the back teeth.
- They are more split-resistant, stiffer, and stronger than glass ceramics and dental composites.
- Zirconia dental crowns require less tooth structure to be removed in order to be placed.
The disadvantages of zirconia dental crowns:
- The opaque appearance of a zirconia crown can make it appear less than natural and it's difficult to match the material color to your natural teeth
- The zirconia crown’s hardness may wear down opposing teeth.
The drawbacks of zirconia crowns are minor. However, when properly cared for, most dental crowns will last between five and fifteen years. Their longevity will be determined by your oral hygiene, among other factors. To increase their longevity, strict oral hygiene practices must be followed:
- Brush your teeth after every meal and floss regularly.
- Maintain oral hygiene by using antimicrobial mouth rinses and tongue scrapers.
- Don’t neglect dental cleanings and checkups. These dental visits can help keep teeth clean and bacteria-free, while also allowing the dentist to examine the crown's health.
