A dental crown is a tooth-shaped cap that is placed on top of damaged teeth. It restores a tooth’s strength, size, and appearance. A crown is a long-term restoration that can correct major problems like fractures, decay and severe sensitivity.
A dental crown can be made from various materials including metals, porcelain, and resin. The cost of a crown depends on its material and type.
All-ceramic crowns
All-ceramic crowns offer strength and a natural appearance. They can be used to restore fractured, decayed and worn teeth. They can also be used to cover dental implants. They are available in a range of shades to match the colour of your teeth. They are often recommended for front teeth but can be used on other teeth too.
These dental crowns Antioch TN are made of a ceramic core and veneers. They are sometimes prone to delamination and fracture of the veneers.
Feldspathic porcelain is a traditional and standard porcelain material that can be bonded directly to the tooth (which transmits the underlying natural tooth colour through the crown) or layered over a pre-built core. Leucite reinforced pressable porcelain offers lifelike translucency and can be fabricated to match the shade of adjacent teeth. The monolithic ceramic crown is milled from a uniform block using a CAD/CAM machine and is extremely hard but less aesthetic than the bi-layered type.
All-porcelain crowns
All porcelain crowns are a ceramic tooth restoration that comes closer to matching natural teeth than other types of crown. They can be coloured in many different shades to match the colour of your surrounding teeth. They are very strong and durable, and will last a long time if well maintained. They also do not stain like other materials, so they require less maintenance. We offer a variety of different all-porcelain crowns for our patients.
The all-porcelain dental crowns Antioch TN offered by VC Dental are made through a process that is much more precise than the traditional resin/composite crowns. First, the crown is shaped and an impression is taken using digital scanning or reliable putty-like impression material. This model is sent to the laboratory where the new crown will be fabricated. The crown is then bonded to the existing tooth. There are several all-porcelain crowns available including Procera, Empress, IPS e.max, and Lithium Disilicate. Procera crowns are a type of high-strength pressed ceramic with an aluminium oxide core that has a superficial layer of feldspathic porcelain that is custom layered on top.
Feldspathic porcelain crowns
Dental crowns are coverings that fit over damaged, decayed or unattractive teeth. They can also replace missing teeth, preventing the shift of surrounding teeth into the empty spaces (called malocclusion) and alleviating problems such as jaw pain and temporomandibular joint (TMJ) disorders. In general, a crown requires less of the original tooth structure to be removed than dental veneers and can last longer.
Feldspathic porcelain has a high translucency and closely resembles the color of natural teeth. However, it is not as strong as lithium disilicate or zirconia ceramics.
Solid-sintered monophase ceramics are made by directly sintering crystals without any intermediate matrix. This makes them much stronger than traditional crown materials and can withstand large biting forces. They can be fabricated using a number of methods, including injection molding and hot pressing. However, they are difficult to work with and require higher temperatures and sintering shrinkage techniques. This is why they are best suited for inlay and onlay restorations.
Metal crowns
Metal crowns are a sturdy restoration that can withstand the biting and chewing forces of the back teeth. They are also less invasive than other types of crowns and can preserve more of your natural tooth structure. However, they can cause sensitivity to hot and cold liquids because the metal conducts heat. They are also not suitable for patients with a history of metal allergies.
Metal alloys are typically used to make dental crowns Antioch TN and they can last for years. They are also a good choice for out-of-sight molars. They are durable and do not chip easily, but they are not as attractive as porcelain crowns and may show through your smile when you smile.
Most metal crowns contain noble metals like gold and silver, but some contain nickel or mercury. These metals do not interact well with the body, and nickel can tint gums green and cause a severe allergic reaction. The mercury in some metal alloys may even leak into the bloodstream, causing a variety of health problems.
