Does anybody know anything about lava crowns?

I need to know how I can teach patients about lava crowns. They are the porcelin crowns with the zirconia coping inside. They are asthetic and beautiful crowns. If there are and Dentists out there or assistants or anybody in the dental field that know of these crowns and of good ways to teach patients about them some advice would be great. Thanks.

Lava Dental Crowns





Grinding your teeth, an improper bite, age, fillings and tooth decay can all be contributing factors in the wearing down, cracking or breakage of your teeth. If you suffer from this problem, dental crowns can be the solution. Dental crowns cover the entire visible surface of your affected tooth to add strength, durability and tooth stability.





Traditionally dental crowns were made of metal, more notable gold. With further development, ceramic (porcelain) dental crowns were developed to produce a more natural appearance. Significant advancements have since been made, with Lava dental crowns generating a considerable buzz in the cosmetic dentistry industry.





Lava dental crowns present an innovative computer-aided design/computer-aided manufacturing (CAD/CAM) technology to produce an all-ceramic crown on a zirconia base. Lava dental crowns were created by the need for all-ceramic dental restorations in the posterior region, which is an increasingly important aspect of dental care. Until Lava dental crowns, there were no real suitable ceramics or economic processing procedures available. With the new LAVA system, it will be possible to satisfy these demands in the future.





The Lava system is based on the machining of presintered zirconia, which, due to its outstanding mechanical properties, its biocompatibility, and its excellent esthetics in combination with a specially designed veneer ceramic, is the ideal candidate for these applications. Presintering is the process of heating of a compact at a temperature below the normal final sintering temperature to increase the ease of handling or shaping the compact. Zirconia is a high-tech ceramic material that is characterized by its outstanding stability and biocompatibility, as well as strength levels that are significantly higher than other all-ceramic materials. In addition to strength, Lava all-ceramic system restorations display excellent esthetics and precise fit characteristics. In combination with a corresponding CAD/CAM unit, the use of an easy-to-machine presintered ceramic material allows for the first time a reliable, fully-automated and thus, fast manufacturing of the Lava Dental Crown.





The advantages of Lava Dental Crown is summarized:





* Excellent esthetics and translucency


* Outstanding marginal fit


* Superior strength of zirconia with high fracture resistance


* 8 shades of zirconia framework


* Ideal for 3-unit bridge applications


* Successful 3-year clinical trial





The esthetics and biocompatibility of Lava restorations represent the optimum in all-ceramic systems. Many cosmetic dentists today are shifting towards the use of Lava Dental Crowns. They are surprised by the results - Excellent clinical margin, fit and stability, and superior aesthetics. Preparations require removal of less tooth structure, and cementation can be accomplished using proven, conventional techniques.





If you want a natural and lasting change to your smile while optimizing length, rotations and alignment problems, then Lava denture crowns can reshape and whiten your teeth and improve your smile dramatically.
