A dental crown is a prosthesis that is constructed to replace a damaged or lost tooth. It is performed by reducing the tooth on all surfaces so that the crowns can be fabricated over it. After tooth preparation, an impression is taken of the upper and lower jaw, so that a dental cast can be created from it. This cast is sent to the laboratory and the prosthesis or crowns are fabricated over them.
The preparation and the design principles involved in the fabrication of porcelain and ceramic crowns for teeth follow a very precise technical science about it so that they can provide an aesthetic and functional restoration. In other words, a properly planned and constructed prosthesis, should somehow feel, look and function like the natural tooth.
Porcelain and Ceramic tooth crowns can be prescribed to solve all kinds of dental issues:
*It can restore a badly carried or fractured tooth that is no longer restorable through traditional means, with a composite resin filling.
*When linked together, the bridgework can replace lost tooth or teeth. The existing natural teeth will be provide support and will hold the bridgework so that a gap can be filled with an artificial tooth.
*It can be constructed so that a patient can enjoy a more beautiful smile that is even in color. It is a perfect cosmetic consideration for those who have badly stained and discolored teeth. Extrinsic stains are deeply embedded in the hard tissues of the teeth and cannot be removed by normal scaling. Porcelain tooth crowns will perfectly mask the appearance of the tooth underneath it and make the smile more attractive.
*For a more permanent whitening effect, a patient can opt to have multiple ceramic or porcelain tooth crowns so that the whitening effect is more lasting and defintely more aesthically appealing.
*In lieu of the more complicated, lengthy and uncomfortable orthodontic treatment, multiple porcelain or ceramic crowns for teeth can be constructed so that a patient can have a properly aligned smile and bite. It can close gaps and spaces and straighten crowded, rotated and tipped teeth — so that a patient can feel more confident about his smile.
*It is the most ideal restorative treatment for teeth that received root canal therapy. Extirpating or removing the pulp renders the tooth more brittle and to prevent fracture and damage after a root canal treatment, porcelain tooth crowns are prescribed as the final restoration to afford the tooth more strength.
Ceramic vs. Porcelain Tooth Crowns:
There no big difference between porcelain and ceramic crowns for teeth. Both effectively satisfy patients’ aesthetic considerations because the material can be chosen carefully so that it matches the color and shade of any existing natural teeth. It is strong enough to support force and load and when it is reinforced by a metal of zirconium core, it is given even better strength to perfect function to the mouth of patients.
In a close comparison, surely ceramic crowns for teeth cannot rival the strength and power of porcelain tooth crowns, but they both offer superb capabilities.
