What is a Dental Crown?
A dental crown is a tooth-shaped “cap” that is fixed over a tooth — to cover the tooth and restore its shape, size, strength, and improve its appearance. The crowns fully encase the entire visible portion of a tooth that lies at and above the gum line, when cemented into place. Below are a few of the Dental Crowns we offer.
Zirconia crowns are 100% metal-free crowns made from zirconia. This material has flexural strength as high as metal-ceramic restorations but has an aesthetic and natural look due to its translucency. Being metal-free, it has no chance of gingival darkening and exposure of metal margins when gums recede. Our zirconia crowns are highly aesthetic as they are matched to the shade of the adjacent tooth. These are also the most robust material available for people with bruxism or grinding habits as they do not wear off. Thorough color penetration till the restorations ensures higher shade consistency and limits any shade variation after occlusal adjustment.
E.max crowns are the next generation ceramic crowns made of advanced pressed ceramic, formulated from lithium disilicate crystals. It has greater strength and natural-looking aesthetics. It is metal-free and biocompatible, eliminating dark margins. It has high strength, enhanced translucency, and resistance to fractures. It is indicated mainly for crowns in anterior teeth due to its superior aesthetics. Posterior single crowns can also be done. When versatility, dependability, and durability is of paramount importance, e.max crowns are the un matched choice.
Metal Ceramic Crown (PFM)
Metal ceramic, as the name suggests, is a combination of a metal base with porcelain coping. The metal base provides a natural hue of dentin from within, that is
complimented by porcelain coping. These can be made of high noble, semi-precious, or precious metal alloys. They are known for strength, versatility and have been in used by dentists for over 60 years. They have strength, integrity and marginal adaptation. Thus they are highly durable. These crowns have been known to have a longevity of 30+ years with appropriate oral hygiene practices. These can be used for both anterior and posterior crowns but preferable for posterior crowns due to high strength. It is essential to avoid these in patients with specific metal or alloy allergies.
Full cast gold metal crowns are known to be the most wear-friendly materials available. They can remain in the mouth without any wear or tear for decades. They are known to last up to 30 to 40 years with appropriate oral hygiene practices. They have excellent biocompatibility. Fewer microbes can adhere to the crown due to the highly polished surface and thin margins, resulting in high plaque resistance. Though they are known for longevity and durability, they are not aesthetic and are preferred in posterior regions. It is also essential to avoid these in patients with specific metal or alloy allergies.
CAD-CAM Temporary Crown
A temporary or provisional crown is a short term crown placed for an interim period. The temporary crown is designed using CAD/CAM technology to form an accurate tooth shape. A temporary crown is needed to protect the prepared tooth, prevent damage to the periodontal tissues and gingiva. They also serve to disguise the prepared tooth to a certain extent; until the final crown can be delivered. These CAD-CAM crowns are a fast and reliable way to save chairside time. Simultaneously, the hardness and resistance of this material are perfect for the preparation of provisional pieces.
