Exploring the Variety: Types of Dental Crowns and Their Benefits

Crowns are tooth-shaped caps that cover a damaged, cracked or broken tooth to restore its appearance, shape and strength. There are many different types of crowns, but the most important factor is what’s best for your individual needs.

Feldspathic porcelain has a translucent quality and can be bonded directly to the natural tooth surface (transmitting the underlying tooth colour) or layered over a core. They are very durable and withstand biting and chewing forces well.

Ceramic

Ceramic crowns are popular with patients who prioritize the aesthetics of their restorative outcome, as they look closest to a natural tooth. They are also ideal for bruxers and those with metal allergies as they are free of mercury, unlike some types of metallic dental crowns Antioch TN.
Ceramic crowns can be fabricated using either porcelain-fused to metal

(PFM) or solid ceramics such as IPS e.max. PFM crowns are very durable and provide a great fit, as they require less of the natural tooth to be filed down. However, they are not the best choice for front teeth due to their metallic appearance.

IPS e.max crowns are fabricated from biocompatible lithium disilicate ceramic glass ingots and have a high flexural strength of 400MPa. They can be pressed or milled and a veneer placed on top to create a highly aesthetically pleasing result. These are excellent choices for anterior restorations and can be crafted as monolithic full-contour or as conventional pressed ceramic crowns.

Zirconia

Zirconia crowns are incredibly strong. In fact, they are a popular choice for the back teeth because of their durability, especially since they can withstand the pressure that is placed on these types of teeth from chewing and grinding. Unlike porcelain, zirconia is not prone to chipping or fracture.
In addition to their strength, zirconia dental crowns antioch tn also look more natural than PFM or porcelain restorations due to the lack of metal. Zirconia also allows dentists to be more conservative in their preparation which results in less of the original tooth being removed.

Another great advantage of zirconia is its stain resistance. Zirconia resists staining better than most other materials, which means patients can enjoy their favorite foods (including dark berries, caramel-colored sodas, coffee, tea and tomato-based sauces) without worrying about discoloration to their crowns. This makes them a great choice for people with sensitive teeth. However, patients still need to brush and floss their crowns regularly in order to avoid plaque build-up that can cause tooth decay and sensitivity.

Emax

Emax dental crowns Antioch TN are made of lithium disilicate glass ceramic. These are the newest in crown technology, offering superior durability and aesthetics. This material is also very translucent, allowing it to conceal discoloration well, even in darker teeth.

A material’s ability to withstand impacting stress is known as its flexural strength. In a clinical context, this affects the amount of biting stress that the restoration can withstand and its overall durability. It also impacts the capacity to construct long-span bridges and total wall thickness of the finished restoration.

This is one of the main differences between IPS e.max and zirconia: a greater flexural strength supports more versatile, less-invasive dentistry. In addition, IPS e.max can be fabricated to form multiple types of restorations including inlays, onlays, veneers and screw-retained anterior bridges as well as short-span bridges for missing front teeth. It’s also compatible with existing dental work, and is a great option in areas of the mouth with high esthetic demand.

All Resin

These crowns are mainly used as temporary crowns and are a metal-free alternative to stainless steel crowns. They can be mixed in a range of shades to match the natural teeth colour and therefore are more aesthetically pleasing. They are a cost-effective solution for restoring baby teeth which have undergone pulp therapy (baby root canals) and are expected to be lost when the permanent tooth erupts.

A major disadvantage of this type of crown is that it is more prone to chipping if a patient is not careful or eats hard food. This can lead to a crack in the chewing surface of the tooth and allow bacteria to enter the cavity.
These crowns are usually made of feldspathic porcelain and can be bonded directly onto the natural tooth surface (which transmits the underlying tooth color through the porcelain) or layered over a pre-built core. These crowns are more brittle than porcelain fused to metal crowns and they also lack the support of noble metals so are more prone to fracture than other dental crown types.
