All Ceramic Method Of Dental Crowns

By: Anne Fields

Dental crown is one of the earliest forms of dental restoration procedures used to restore damaged tooth. According to the cosmetic dentist hollywood, common materials used for dental crowns include gold. But because of today's advanced technologies and unrelenting efforts to further improve practices, dental crowns aren't only available in gold, but also in metal-free materials, particularly with ceramics.

Methods of ceramic restorations

*

CEREC - The CEREC method of fabricating all-ceramic restorations involves electronically capturing and storing a photographic image of the prepared tooth and, using computer technology, crafting a 3D restoration design that conforms to all the necessary specifications of the proposed inlay, onlay or single-unit crown; there is no impression. According to the cosmetic dentist hollywood, over 95% of the restorations made using CEREC and Vita Mark I and Mark II blocks are still clinically successful after 5 years. Further, at least 90% of restorations still function successfully after 10 years.

Empress - Similar to a lost-wax technique, the empress is a specially designed pressure-injected leucite-reinforced ceramic which is pressed into the mold by using a pressable-porcelain-oven, as though the final all-ceramic restoration has been "cast." The Empress can be utilized for anything the lost-wax technique can be used for, in addition to veneers (which would not be made of cast metal).

Procera - Procera AllCeram, owned by Nobel Biocare, is a CAD/CAM based method which produces a crown by overlaying a very durable ceramic coping of either alumina or zirconia, referred to as a "core", with Vitadur Alpha porcelain. Introduced in 1991, Procera can now be used to produce crowns, bridges and veneers.

Comparison of All-Ceramic Restorations and Gold

Inlays, onlays and all varieties of crowns can also be fabricated out of ceramic materials, such as in CAD/CAM technology. Although naturally-colored and thus perhaps more aesthetically pleasing than gold, and obtained with less time spent at the dentist's office (CAD/CAM technology allows for immediate, same day delivery of the restoration), ceramic restorations, according to the cosmetic dentist hollywood, cannot be finished, polished or burnished at the margin as gold can, and thus possess a significantly lower level of marginal adaptation than gold.

In addition, the mechanical properties of gold that make its restorations superior to that of amalgam or composite, including but not limited to the properties of stress, strain, fatigue, creep, compressive and tensile strengths, modulus of elasticity, biocompatibility, elastic and plastic deformation, resilience and toughness, also make it superior to the ceramics utilized in CAD/CAM technology as well as the other all-ceramic restorations. According to the cosmetic dentist hollywood, all-ceramic restorations may appear to be more beneficial than gold, but long term benefits are certainly restricted to that of aesthetic concerns, which is a subjective issue that should be seriously weighed against the considerable benefits of gold.
